        <p>The aim of the current paper is to formulate a conception of pragmatic patterns characterizing the construction of individual and collective identities in virtual communities (in our case: the Twitter community). We have explored several theoretical approaches and frameworks and relevant empirical data to show that the agents building virtual communities are 'extended selves' grounded in a highly dynamic and compressed, linguistically mediated virtual network structure. Our empirical evidence consists of a study of discourse related to the Latvian parliamentary elections of 2010. We used a Twitter corpus (in Latvian) harvested and statistically evaluated using the Pointwise Mutual Information (PMI) algorithm and complemented with qualitative and quantitative content analysis.</p>

      <title>1 Introduction</title>
      <p>In this paper, we explore the pragmatics of political messages in Latvian Twitter
communication during the 2010 general election.</p>
      <p>The results contain a topical analysis of election discussions as well as an analysis
of hashtags and retweeted messages. The fast pragmatic dynamics in Titter
communication can be observed through hashtags, showing a rapid reaction of
Twitter users to the elections, while top retweets support the findings of content
analysis with regard to political sentiment. Content analysis reveals the possibility of
significant discrepancies in terms of the cognitive and physical distances between a
group and its individual members in their identity generation processes. In view of the
results, we propose a hypothesis that reveals correlations between a group and its
individual members, the richness of topics, channels of communication, frequency of
mention, and connotations and effects of messages.</p>
    </sec>
    <sec id="sec-2">
      <title>2 Theoretical Background</title>
      <p>
        We assume that the generation of identity takes place through two simultaneous and
mutually interdependent social categorization processes – belongingness and
differentiation [3,4]. Our study undertakes to examine these two processes in action,
constrained by two selection criteria: (
        <xref ref-type="bibr" rid="ref1">1</xref>
        ) Twitter messages only, and (
        <xref ref-type="bibr" rid="ref2">2</xref>
        ) messages
relating directly to national politics. The homogeneity of format and topic draws
attention to similarities and differences in content and in discourse strategies.
      </p>
      <p>Twitter is a particularly fruitful resource for this type of analysis because its brevity
constraint gives rise to an abundance of shortcut techniques including expressive
lexis, the use of abbreviations and hyperlinks for proper names and keywords. Rigid
information hierarchies reveal what users presume to be already known and/or shared
by their in-group, and are a fertile soil for the investigation of presuppositions,
cultural common ground, and cultural discrepancies [6,7,15]. This is especially
prominent in Twitter discourse about politics, a topic where speakers generally
exhibit willingness to report their opinions despite the fact that their perspectives are
often conflicting. Although political opinions are usually articulated explicitly,
belongingness to an identity group1 may be partly implicit [19].</p>
      <p>We focus on mechanisms of self-identification, formation and maintenance of
ingroups and their differentiation from out-groups. The findings attempt to answer the
following questions: 1) How are virtual political identities generated and maintained
in a condensed public mode of communication? 2) What are the pragmatic
instruments that help to achieve these processes?</p>
      <p>Twitter can also help to understand implicit social categorization. Typically,
research on social categorization is conducted using questionnaire or focus group
methodologies, mainly addressing explicit political categorization. This study has
incorporated some implicit factors of analysis, often crucial in political
communication. Approaching human-generated digital content as empirical material
for categorization analysis is not new (cp. [9]). Analysis of political messages on
Twitter, although not directly focused on categorization, is also provided by several
studies (cp. [22]). Several recent studies explore possible correlations between
election outcomes and the level of Twitter activity of politicians (US Congress: [14],
South Korea: [12]). This study, however, also analyzes political messages created by
media organizations and other active users.</p>
      <sec id="sec-2-1">
        <title>2.1 Collocations and concordance analysis</title>
        <p>Co-occurrence statistics allow to quantitatively project some of a word’s semantics
grounded in users’ categorization performance ([18]). Collocations show the relative
most frequent (sometimes stereotypical, implicit) social categories in communication,
but the research must be complimented with concordance analysis for semantic
complexity. Of course, the output of such a combination of methods concerns the
group (and not individual) patterns of social categorization, and pragmatic effects are
related to statistical frequency of language used in communities and not to individual
patterns of communication2.
1 We define identity as a continuous process where the sense of belongingness to a community interacts
with the desire to be a unique individual. A community has an internal and an external structure
(relationships within the group and relationships with other groups), and community identity can
generate polarization effects.
2 A pragmatic pattern is a typical way of using language in a linguistic community (e.g., in social media).

        <title>2.2 Political messages</title>
        <p>Studies show that people frequently have difficulty explicitly articulating their
ideology [19]. Thus self-report, focus groups, and questionnaires may often prove
inadequate for analyzing political categorization. Ideological labels, moreover, may
not correspond to subjective conceptions of beliefs, and undecided voters exhibit a
much clearer opinion via implicit tasks than via explicit ones [19]. Political categories
are distinguished above all by their extreme polarization (cp. [11,17]). On Twitter,
initially informative messages are modified to become increasingly polarized [23].</p>

        <title>2.3 The Latvian Parliamentary Election 2010</title>
        <p>The Saeima (the parliament of Latvia) is elected using a proportional multi-partisan
representation system for 100 seats. The 2010 election saw 13 competing political
parties or their alliances. Candidates from 5 parties were elected: 33 seats for “Unity”
(Unity), 29 seats for “Harmony Centre” (HC), 22 seats for the “Union of Greens and
Farmers” (UGF), and 8 seats each for the National Association “All For
Latvia!”“TB/LNNK” (NA) and “For a Good Latvia” (FGL). The turnout for the 2010
elections was 63.12% or around 967 000 people.

      <title>Methodology and Design</title>
      <p>
        The aims of this study are: (
        <xref ref-type="bibr" rid="ref1">1</xref>
        ) to build a feasible methodology using content and
structural analysis of social media (in particular, Twitter) with respect to political
communication; (
        <xref ref-type="bibr" rid="ref2">2</xref>
        ) to explore correlations between the election results and the
representations of political parties and their candidates in Twitter communication; (
        <xref ref-type="bibr" rid="ref3">3</xref>
        )
to explore the identity generation of political actors in pre-election communication on
Twitter.
      </p>
      <p>We collected a dataset of tweets covering the election week, performed careful
manual extraction work and numerous statistical comparisons. We also created
custom tools for analyzing Latvian Twitter content including a concordance tool. We
believe that this makes our results, in several respects, even more precise than, e.g.,
[22] who automatically translated their corpus of empirical data (German tweets) into
English and only then processed it with LIWC (Linguistic Inquiry and Word Count).</p>
      <sec id="sec-3-1">
        <title>3.1 Dataset</title>
        <p>The dataset consists of one week of Twitter messages (from 28-Sep-2010 to
04-Oct2010) from a subset of Latvian Twitter users, including 4 days before the election, the
day of the general election (October 2) and 2 days following the election. The total
size is 50'032 messages, consisting of: 50% regular tweets; 18% retweets; and 32%
replies. There are no publicly available official data about the total number of Twitter
participants in Latvia. According to local media experts, the estimate is approximately
40'000 users (November 2010).</p>
        <p>
          In order to choose a topically relevant set of Twitter accounts, we started with a
manually selected set that included (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) accounts of political parties and their
#MSM2011
candidates to the Parliament (Saeima); (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) accounts of media organizations, political
analysts, and other individuals who write about politics and the election; and (
          <xref ref-type="bibr" rid="ref3">3</xref>
          )
accounts of individuals most active in the Latvian Twitter-sphere. This formed an
initial set of 179 accounts to follow. We enlarged the set of accounts by (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) retrieving
tweets from the current set of accounts; (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) identifying new accounts mentioned in the
tweets collected; (
          <xref ref-type="bibr" rid="ref3">3</xref>
          ) filtering out accounts not related to Latvia; and (
          <xref ref-type="bibr" rid="ref4">4</xref>
          ) repeating this
process. The result is a total of 1'377 user accounts to collect tweets from.
        </p>
        <p>We did not choose a random sample to avoid large amounts of redundant data
consisting of ordinary discussions unrelated to our research interests - politics,
identity generation, and the media. This intentionally selected dataset allows for a
more precise analysis of the above research topics.</p>
      </sec>
      <sec id="sec-3-2">
        <title>3.2 Tweet Processing and Analysis</title>
        <p>Collected tweets are processed using the NLTK library [1]. The processing of tweets
consists of: cleaning the dataset; saving the full tweet data for structure analysis;
tokenizing tweets; replacing keywords, where we consolidate the various ways to
write the same word or expression and replace it with a single keyword identifier.</p>
        <p>Latvian is an inflected language in which the same word may appear in many
forms. In the keyword replacement step, we collapse these forms into one keyword.
We also replace different ways of writing the same expression (e.g. abbreviations and
full names of party names). Since there was no stemming or lemmatizing software for
Latvian that we could use, we created our own keyword replacement map for
keywords related to elections.</p>
        <p>
          Having processed the tweets, we performed: (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) content analysis in which we
examined the text content of Twitter messages; and (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) structure analysis, in which
we examine the metadata in tweets and associated with tweets. The main types of text
processing performed in the content analysis phase are concordance lookup, word
frequency analysis, and collocation (bigram) analysis. For collocation ranking, we
used the Pointwise Mutual Information (PMI) metric [16].

      <sec id="sec-4-1">
        <title>4.1. Representations of the candidates on Twitter</title>
        <p>We made a list of all 1234 candidates competing for seats in the parliament, exploring
their representations in selected tweets during the 4 days leading up to the election.
Since only a small part of all candidates were represented in Twitter communication
(in our dataset) four days before the election, we wished to compare our findings with
publicity coverage of the candidates in other media in Latvia.</p>
        <p>
          We identified 79 family names of the candidates occurring in collocations in the
Twitter dataset, and 170 family names of the candidates occurring in the media
monitoring dataset. We distinguish four groups of candidates: (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) those represented
both in Twitter and print media and news agencies (44 candidates or 3.56% of all the
candidates); (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) those who are represented mostly in Twitter (6.40%); (
          <xref ref-type="bibr" rid="ref3">3</xref>
          ) those who
are represented mostly in print media and news agencies (7.37%); and (
          <xref ref-type="bibr" rid="ref4">4</xref>
          ) those who
are mostly not represented in the media we studied (82.67% of all the candidates).
#MSM2011
        </p>
        <p>
          Further, we listed how many personal tweets, collocations and publications occur
with every of the family names in various time periods (the average number of
collocations of every family name of the candidates four days before the election is
4.68; later, we included only those (
          <xref ref-type="bibr" rid="ref9">9</xref>
          ) family names that are statistically significant
with respect to their number of collocations (n ≥ 4.68)). Almost all of these candidates
(except one) were elected1. They also represent 4 out of the 5 parties elected to the
parliament. We analyzed the split of the 100 elected candidates between four
previously distinguished groups of candidates. Our calculations show that 32% of
elected candidates correspond to the first group (represented in Twitter, print media,
and news agencies); 5% correspond to the second group (mostly represented in
Twitter); 42% correspond to the third group (mostly represented in print media and
news agencies); and 16% correspond to the fourth group (mostly not represented in
the media we studied). Based on all of the above, we have formulated a working
hypothesis: (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) the more thematically varied and (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) the more frequent the
communication, and (
          <xref ref-type="bibr" rid="ref3">3</xref>
          ) the more communication channels are used to mention a
candidate, the higher the probability that he or she will be elected to parliament.

        <title>4.2 Representations of the parties on Twitter, in print media, and by news agencies prior to the election</title>
        <p>
          For names of political parties (Table 1) we listed: (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) how many collocations occur
with each name; (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) how many publications from print media and news agencies
mention each name; and (
          <xref ref-type="bibr" rid="ref3">3</xref>
          ) the results each party has achieved in the election. Every
party with an above-average number of collocations in Twitter communication before
the election (8.46) is elected to the parliament. An exception is UGF, which was
elected despite a below-average number of collocations. We assume that the latter
was compensated in the long term by the highest number of publications in print
media and news agencies. However, with the high ranking of mention on Twitter
before the election (41 collocations), FGL obtained significantly fewer parliament
places than “Unity” or other political parties with a lower ranking of mention on
Twitter. Initially, it can be assumed that FGL was affected by relatively lower
publicity rates in print media and news agencies; but in fact, FGL had conducted a
more extensive advertising campaign than any other political party). Further
investigation points to an important qualitative factor. A review of collocations of
FGL and “Unity” in a detailed concordance analysis leads to the observation that the
“Unity” collocations feature more positive connotations than the FGL collocations.
This allows us to emphasize and modify our above hypothesis regarding the
candidates: (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) the more thematically varied and (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) the more frequent the
communication, and (
          <xref ref-type="bibr" rid="ref3">3</xref>
          ) the more communication channels a political party is
mentioned in positively, the higher the probability that it will be elected to the
parliament.

        <title>4.3 Identity-generation processes for political parties and individuals in</title>
      </sec>
      <sec id="sec-4-4">
        <title>Twitter communication</title>
        <p>Two political parties – FGL and “Unity” - have significantly higher rankings of
mention than other parties. Moreover, their candidates for the post of Prime Minister
(Ainārs Šlesers (FGL) and Valdis Dombrovskis (Unity)) have similar rankings of
mention. In spite of these similarities, the two have strikingly different election results
(“Unity” won the election and got 33 seats in the parliament, with Valdis
Dombrovskis approved as the prime minister, while FGL got only 8 seats in the
parliament). This led us to investigate more closely the identity generation of these
individuals and organizations through political categorization in pre-election tweets.
First, we identified 10 collocations of significantly high ratings for the four name
keywords. Secondly, we used concordance analysis to examine the semantics in each
collocation.</p>
        <p>We have listed in Table 2 what percentage of the topics bear positive, neautral or
negative connotations and how many topics are covered by each of the keywords. As
Table 2 demonstrates, the individual and the organization are categorized similarly in
the case of Šlesers and his political party FGL: both are more related to negative
topics than positive ones. The case of Valdis Dombrovskis and his political party
“Unity” is different: the individual is mostly categorized in positive or neutral topics,
while the political party is categorized in negative or neutral ones. This shows that the
generation of identity of an organization and that of its individual members may
#MSM2011
involve significant discrepancies in terms of cognitive versus physical distances4. In
this case, the cognitive distance between Dombrovskis and “Unity” is bigger than the
‘physical’ one. This may be in part due to the fact that the “Unity” election campaign
focused exclusively on Dombrovskis, promoting him as the principal benefit to the
voters. Thus the individual became more cognitively important than the whole (an
organization).</p>
        <p>
          This allows us to expand our hypothesis regarding politicians and political parties
as follows: (
          <xref ref-type="bibr" rid="ref1">1</xref>
          ) the more thematically varied and (
          <xref ref-type="bibr" rid="ref2">2</xref>
          ) the more frequent the
communication, and (
          <xref ref-type="bibr" rid="ref3">3</xref>
          ) the more communication channels are used to mention a
member of an organization (in this case, a politician) positively5, the higher the
probability that he or she will become cognitively more important than the
organization (in this case, the political party) and cause a shift in the perception of the
significance of the organization.
In this section, we analyze Twitter messages by examining implicit and explicit
metadata and structural information contained in tweets.
Hashtags were used in 2'238 tweets (4.47% of all tweets). In total, 750 different
hashtags were used 2'668 times. Most hashtags were used just once. 29.06% of
hashtags (218) were used more than once and 2.26% (
          <xref ref-type="bibr" rid="ref17">17</xref>
          ) were used at least 20 times.
        </p>
        <p>The most popular hashtag was #velesanas (“election”), used in 459 tweets (17.2%
of tweets containing hashtags). Other election-related hashtags that were used at least
20 times include #nobalsoju ("i voted"), #politsports (political sport), #pietiek
4 In the Spreading-Activation Theory, assuming a correlation between the collocational structure of the
corpus and the mental models of its users, collocational structure reflects the cognitive distance between
conceptual entities such as political parties and individuals. Indirectly connected nodes are more distant
than directly connected ones.
5 Using manual concordance analysis, connotations are determined and generalized according to three
categories (positive, neutral, and negative), determined individually for each tweet. Examples include:
“Friends, tomorrow I shall vote for Dombrovskis, because I trust his professionalism …” (positive);
“Šlesers doubts the objectivity of social media …” (neutral); “Dombrovskis: a protégé of corruption or a
racketeer?” (negative).
#MSM2011
("enough!"), #vēlēšanas (#velesanas with Latvian diacritics), #cieti (“solid” – a slogan
of FGL), #twibbon (twibbons were used to show party support).</p>
        <p>For the purposes of this paper, we limited Table 3 to hashtags related to politics.
Most of the top 10 hashtags on election day were related to politics (9 out of 10) and
appear in the table. Other days had less election-related tags, but also a lower hashtag
usage activity in general. The #velesanas (“election”) hashtag appeared the day before
the election and had a remarkable spike in its usage on election day and the day
following it, receding back to background level the day after that.</p>
        <p>Hashtags that retained popularity for at least 4 days in this 5 day period were the
journalism tags #pietiek and #ir. Both refer to publications seen by top Twitter users
as prestigeous and integral organizations for investigative journalism. The hashtag
#sleptareklama ("hidden advertising") coincided with the appearance of controversial
hockey-related advertisements that were suspected of containing hidden political
advertising. A creative usage of a hashtag is its syntactic integration into a sentence: a
notable example is using #ir, the magazine whose name literally means “is”, as a
verb: e.g., “There #is still time to form a new coalition”.</p>
        <p>Apart from the obvious purpose of attracting attention to major topics, hashtags
carry the connotation of familiarity with the object of the tag, be it a topic, an
individual, or an organization – at the very least, one must know what is worth
tagging. Tags help to define group identity in two recursive ways: by highlighting
issues considered important by the group, and by presenting the group as the kind of
community where such issues are considered important.

        <title>Analysis of Retweeting</title>
        <p>We considered a retweet any Twitter message that contains the string "RT
@nickname" (17.68% of the selected dataset). Most retweets start with "RT
@nickname", i.e. are marked as such and point to the original message. These results
shows more uniformity of retweet formats than reported in [2], possibly a result of
more officialized retweet functionality. For further analysis, we used retweets which
#MSM2011
contained information about the original tweet (i.e. 90.46% of all retweets). An
analysis of the top 20 most retweeted posts reveals that 70% of these posts are directly
related to the elections; 10% are loosely related; 20% are unrelated.</p>
        <p>There were 14 election-related messages among the 20 most retweeted messages.
Of these, the majority (8 out of 14) were satirical tweets criticising a political party or
a politician. Seven refer to FGL or its prominent members Ainārs Šlesers and Andris
Šķēle. Other parties mentioned in these retweets were HC and FHRUL (one tweet
each). The two most retweeted messages are related to the election.

        <title>Opinion leaders and in-group demarcation mechanisms</title>
        <p>The content of top retweets and hashtags reveals that the opinion leaders in the
Latvian Twitter-sphere, the in-group that enjoys the highest popularity and prestige,
can be vaguely defined as a group of centrists who see themselves as positioned
between two perceived polarities. The cognitive space, as regarded by the in-group,
can be characterized thus: to the left are krievi (“the Russians”), the parties and their
supporters commonly perceived as pro-Muscovite and representing the interests of the
Russian-speaking population (HC, FHRUL). To the right are nēģi (“the parasites” –
an imprecise translation of the word taken from a popular tweet criticising this group),
the nationalist alliance (FGL, NA) that the Twitter opinion leaders see as outdated and
highly corrupt, exploiting their privilege for personal gain. The in-group supports the
political alliance “Unity” and particularly its leader, Valdis Dombrovskis, who was
subsequently elected Prime Minister.</p>
        <p>The fact that the in-group appears to take a centrist position is significant: their
output is less polarizing than could be expected of a highly politicized group. Still,
there is a clear demarcation of the in-group from both out-groups described above.
This is achieved by the opinion leaders of the in-group through several
groupidentity-generating mechanisms and strengthened by the heightened emphasis on the
social self [4], typical of both online communities and political discourse.</p>
        <p>Manipulating cognitive distances is relatively easy in the dematerialized virtual
space, which facilitates impressions of togetherness and mutual identification within
the in-group, on the one hand, but also the distancing of the in-group from out-groups.
Perhaps surprisingly, the brevity constraint of Twitter messaging, rather than
complicating political categorization, can facilitate it: the format is well suited to the
in-group’s simplified tripartite view of the political space. Thus, through repeated
tweeting of negative content containing the letters “PLL” or “PCTVL” (acronyms of
the names of political parties on the two sides of the perceived spectrum), it is soon
enough to write “PLL” or “PCTVL” to evoke a cognitive frame [8] associated with
negative content. Clearly, the details of this content will be unique for each user; but
as long as there is a basic understanding of a commonality of reference – in this case,
of the negativity of the referents – a mention of a party acronym will effectively serve
as an invitation to ‘fill in the gaps’ with each reader’s own meaning [13].
#MSM2011</p>
        <p>Political jokes6, abundant in top retweets, work in a similar manner. Provided that
the humourous effect is usually achieved by inviting the audience to frame-shift
through an unexpected element [7], political jokes on Twitter are doubly rewarding
because they give the audience the feeling of belongingness through having
understood the frame shift without surrounding linguistic context and through a very
limited number of signs. Similarly to a hashtag, a retweet works recursively by
simultaneously flaunting an individual’s understanding (and hence his belonging to
the in-group) and helping to define his individual identity through the content of what
is understood and retweeted.</p>
        <p>Our corpus shows that power and control are very much the preoccupation of
Twitter users, and the independently formed, ‘grass-roots’ community of top tweeters
quickly forms their own behaviour canons. This is typical of online communities,
where a myriad of rules and expectations underlie seemingly free, chaotic
communication [10]. A popular political message on Twitter is at once an expression
of individual and group identity, an invitation to the in-group members to share the
opinion expressed, and a warning about the consequence of deviating from the
group’s norms. By way of illustration, a message retweeted 15 times reads: “I heard
that Šlesers won’t vote for PLL either, because they’re said to be thiefs” (our
emphasis). In addition to cleverly poking fun at the politician by suggesting he will
not vote for his own party, the message succeeds in conveying that the author will not
vote for Šlesers, that he assumes that his in-group members will not do so, and that
anyone who does vote for Šlesers will be seen as voting for a thief and undermining
his or her in-group membership. In short, Twitter conformity mechanisms are just as
compact as the medium itself.</p>
        <p>Yet without a conforming audience, such successful guidance toward a rigidified,
formal categorisation would not be possible (we may well judge the above message as
successful, since it is on the list of top retweets). The tension between individual
opinion and in-group identification (the personal vs. the interpersonal/social self) is
resolved through a balance of stereotyping processes: just as the political parties and
actors are stereotyped to fit into one of the few cognitive categories carved out for the
occasion of the election, so the individual members engage in a certain degree of
selfstereotyping [20]. Members will be more willing to overlook differences of opinion
and concentrate on their commonalities (real or imagined) when membership is seen
as beneficial, and particularly if the group is seen as working toward a common goal
of some sort – in this case, victory in the parliamentary elections [4]. Because
intragroup attraction on Twitter in the run-up to parliamentary election is ideational rather
than interpersonal, the in-group achieves a high degree of political cohesion in part
simply through perceiving itself as a cohesive unit.
6 An example that is comparatively demure and reproducible in an academic paper refers to the leader of
the party perceived as being in the “parasites” group: “A little boy falls. Šlesers helps him up. ‘So, I
guess now you will vote for me?’ ‘I only hurt my foot, not my head!’”.

      <title>Results and Conclusion</title>
      <p>We have formulated a correlation according to which three factors contribute to the
efficiency of political messages in the electoral discourse – in particular, for a given
collocation bigram: (a) the variety of thematic contexts of occurrence, (b) the
frequency of mention, (c) positive connotations. (While there are other factors
determining efficiency, this study has focused on popularity-oriented facets.) We have
therefore extended the results stated by [12, 14] regarding the correlation between
minority parties, Twitter activity, and election results. The dynamics of Twitter users’
interest in the event (the election) can be observed through hashtag usage and the
most retweeted messages. Top retweets, in turn, convey user sentiment toward
political parties and individuals.</p>
      <p>We have noted instances of discrepancy between attitudes toward individual
politicians as opposed to attitudes toward political groups, and observed that frequent
positive mention of individuals can lead to a heightened cognitive significance of this
individual, causing the perception of the significance of the relevant organization to
recede into the background.</p>
      <p>We envision possible applications of this work in analysis tools correlating Twitter
dynamics with the structure generated from the parameters: (a) the variety of
occurrence contexts, (b) the frequency of mention, (c) positive connotations
(generated semi-automatically). The items which fit into the highest ranking of such
analysis results can be further analyzed manually and a variety of pragmatic effects
(stereotyping, presupposition generation a.o.) might be observed.</p>
      <p>Finally, we can hypothesize that the user of a microblogging resource such as
Twitter extends the sphere of his or her cognitive processing by involving additional
interactive structures of communication. Thus, if we assume that the social
categorization in a community consists of (a) self-categorization as the most crucial
and basic level of identity building, (b) interpersonal communities of individuals, and
(c) large-scale social communities (e.g., national identity communities) including
subcommunities [4], we could argue that self-categorization involves a substantial
amount of extended cognitive processing offloaded onto the digital environment (in
our case, Twitter). In this sense, the results provided by our study can complement
research on the extented mind [5, 21]. A more detailed analysis of the extended self
and offloading effects in cognitive processing is a topic for another study.</p>
