      <abstract>
        <p>Following a shooting attack by two self-proclaimed Islamist gunmen at the offices of French satirical weekly Charlie Hebdo on 7th January 2015, there emerged the hashtag #JeSuisCharlie on Twitter as an expression of condolences for the victims, solidarity, and support for the magazine's right to free speech. A l m o s t s i m u l t a n e o u s l y, h o w e v e r , t h e r e w a s a l s o #JeNeSuisPasCharlie explicitly countering the former, affirmative hashtag. In this paper, we analyse 74,047 tweets containing #JeNeSuisPasCharlie posted between 7th and 11th January. Our network analysis and semantic cluster analysis of those 74,047 tweets reveal that the hashtag in question constituted a form of resistance to the mainstream framing of the issue as freedom of expression being threatened by religious intolerance and violence. The resistance was manifested through three phases: sharing condolences but indicating a reservation against the mainstream frame (Grief); voicing out resistance against the frame (Resistance); and developing and deploying alternative frames such as hate speech, Eurocentrism, and Islamophobia (Alternatives). The hashtag in this context served as a vehicle through which users formed, enhanced, and declared their self-identity.</p>

      <title>2.LITERATURE REVIEW</title>
      <p>
        In order to address the research questions above, the present
study draws upon a combination of three strands of work in the
current scholarship: the network characteristics of
Twittermediated discussion; the roles of hashtags in such discussion; and
the expressions of identity in social media activism. First, recent
years have seen a fast-growing body of literature concerned with
buzzing discussions on the microblogging platform Twitter and
how to examine them systematically. Given the range and amount
of data that researchers could mine from the platform, a keen
interest has been shown in employing network-analysis
approaches for a ‘bird’s eye view’. Himelboim and Han [
        <xref ref-type="bibr" rid="ref11">10</xref>
        ]
argued, through their case study of cancer-related discussion on
Twitter, that communities emerged from such discussion with
clusters of interconnected users and the information sources on
which they relied most. A 2014 special issue of American
Behavioral Scientist, particularly the contributions by Dubois and
Gaffney [5] and Xu et al. [
        <xref ref-type="bibr" rid="ref24">23</xref>
        ], showed that opinion leaders and
influencers could be metrically identified in Twitter-mediated
political discussions. The links formed between political
discussants on Twitter turned out to be considerably different
from those observed in the Web 1.0 environment or in
blogosphere, at least in the South Korean context, according to
Hsu and Park [
        <xref ref-type="bibr" rid="ref12">11</xref>
        ]. Mapping the landscape of Twitter activity has
provided unique insights into various issues of international
relevance. Lotan’s study of the 2014 Israel-Gaza conflict [
        <xref ref-type="bibr" rid="ref13">12</xref>
        ], for
example, visually demonstrated a distinct polarisation between
the pro-Israel and pro-Palestine sides with a negligible number of
bridging actors in-between. By tracing the Twitter network of
Western-origin Jihad fighters, Klausen [
        <xref ref-type="bibr" rid="ref15">14</xref>
        ] identified that certain
strategic roles were assigned to those fighters’ Twitter accounts.
Discussions on Twitter are speedy and unstructured and,
consequently, the organisational usefulness of hashtags has
attracted practical as well as academic attention. Bruns [3]
detailed out his methodological experiences and reflections of
handling Twitter data around a hashtag and highlighted that
hashtags are ‘shared conversation markers’, which require users
to include them in their posts deliberately if they wish to take part
in established conversations. Based on a comparison of various
hashtag-based communications, Bruns and Stieglitz [4]
concluded that different hashtags are associated with different
patterns of user behaviours. While crisis- and emergency-related
hashtags (such as #tsunami for the March 2011 tsunami in Japan
and #londonriots in 2011) have seen a dominant proportion of
retweets and URLs pointing outside Twitter, spectacle-oriented
hashtags (such as British #royalwedding in 2011 and #eurovision
for the Eurovision Song Contest in 2011) seem to elicit more
original tweets from users. Indeed, such findings from hashtag
studies are in line with the studies focusing on unravelling the
network properties of Twitter communications discussed earlier.
Siapera’s work on #Palestine [
        <xref ref-type="bibr" rid="ref20">19</xref>
        ] and Lorentzen’s work on
#svpol (for Swedish politics) [8], for example, point to
homophily and polarisation in hashtag-based discussions,
resonating Lotan’s findings cited above.
      </p>
      <p>
        However enthusiastic the participants in Twitter-mediated
political discussions may be, whether their participations lead to
any concrete outcomes is still an ongoing question. On the one
hand, some offer encouraging anecdotes of how Twitter has
facilitated protests in different parts of the world, such as one
against police brutality in Ferguson in Missouri, US, in 2014 [9].
A cautious voice, on the other hand, is that Twitter and other such
platforms make social movements ‘easier to organise but harder
to win’ by pushing them to scale up before they are ready for it
[
        <xref ref-type="bibr" rid="ref22">21</xref>
        ]. Nevertheless, what social media including Twitter can
certainly provide is a space for accommodating expressions of
identity at multiple layers. Bennett and Segerberg [2] suggested
that, in today’s large-scale ‘connective action’ (in distinction to
the traditional concept of ‘collective action’), political content is
often presented in the form of easily personalised ideas such as
‘Put People First’ (PPF) during the 2009 G20 London summit
protests or ‘We Are the 99 Percent’ during the Occupy Wall Street
movement in the US in 2011. According to the two authors, these
personal action frames are particularly inclusive and can be easily
passed across different platforms. ‘Identity’ here can be a
collective identity expressed within a limited time span like
during one TV programme [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ] or a series [7]. More relevantly to
the purposes of the present study, identity may refer to
individuality that used to be blended and lost in the presence of
the collectivity required in activism in the pre-social media era
[
        <xref ref-type="bibr" rid="ref19">18</xref>
        ].

      <title>3.METHODOLOGY</title>
      <p>
        Our dataset consisted of 74,074 tweets containing the hashtag
#JeNeSuisPasCharlie and published by 41,687 unique users
between 7th and 11th of January 2015. Due to the known limits
of Twitter free API [
        <xref ref-type="bibr" rid="ref18">17</xref>
        ], the data was purchased from Sifter, a
web application that provides, in partnership with Gnip,
searchand-retrieve access to every undeleted tweet in the history of
Twitter. The data gathered via Sifter was automatically imported
into a new DiscoverText project. It was then exported in CSV
format from there and was analysed using R.

      <title>3.1.Typology of contents and network</title>
      <p>The first tweet in the dataset was dated 7th January 2015, 1:46
PM in local time. The hashtag #JeSuisCharlie was reported to be
created at 12:59 PM on the same day, immediately following the
shooting that took place at around 11:30 AM. Tweets in our
dataset were written in various languages. Using the text
categorisation engine based on n-grams provided by the textcat R
package [6], we discovered that French (30%), English (25%)
and Spanish (12%) accounted for the majority of the tweets. It
was unsurprising that French was the most frequently used
language, but the proportion was smaller than expected,
indicating its reference to #JeSuisCharlie. Another interesting
characteristic identified was that 1,488 tweets (2%) were made of
nothing but the #JeNeSuisPasCharlie hashtag. 70% of the 74,074
tweets were retweets and 41% included URLs. Since retweets
account for almost three quarters of the dataset, we computed and
visualised a retweet network with a view to identifying central
users and their clusters if any. We also identified the most
recurring external sources (URLs).</p>

      <title>3.2.Topics</title>
      <p>
        In order to understand the main topics addressed, we applied the
text mining techniques provided by the textcat R package [
        <xref ref-type="bibr" rid="ref17">16</xref>
        ] to
the textual corpus of all tweets in the dataset. We lowered the
case of all terms in the corpus and cleaned it up by removing
auxiliary words in French, English and Spanish, as well as
punctuation marks and whitespaces. Additionally, we also
removed ‘jenesuispascharlie’, ‘charlie’, ‘charliehebdo’, ‘hebdo’,
‘jesuischarlie’ and created a document term matrix to calculate
the associations between the remaining words (N=36,030). After
removing sparse terms (i.e. the sparsity of a term is defined as the
percentage of documents with 0 occurrence; in the present study
a term was removed if its sparsity was higher than 98%), we
identified the most frequently used terms (N=17) and their
Euclidean distances, and created clusters of frequently
cooccurring terms.

      <title>3.3.Evolution over time</title>
      <p>
        To better understand the evolution of the topics discussed, with
particular reference to our third research question, we created a
by-minute time series (N=6,444, AVG TPM=11.5) of activity. We
also used the Breakout Detection R package, which had recently
been open-sourced by Twitter [
        <xref ref-type="bibr" rid="ref14">13</xref>
        ], to identify breakouts or shifts
in the mean of tweet per minute (TPM).
The Breakouts tool (used with the following parameters:
min.size=5, method=’multi’, beta=.001, degree=1, percent=0.25)
detected 14 breakouts (Figure 1), out of which it identified three
moments of high user engagement (Table 1).

Finally, on each subset of tweets created during one of the three
moments, we calculated, using the same procedure applied to the
entire dataset, a document term matrix of the most frequently
used terms. We then grouped those terms according to their
cooccurrences.</p>

      <title>4.DISCUSSION OF ANALYTIC FINDINGS</title>
      <p>
        Adopting the methods suggested in Bruns and Stieglitz’s study
[4], we used two standard Twitter metrics (i.e. ratio between
retweets and tweets and ratio between tweets with URLs over all
tweets) to compare #JeNeSuisPasCharlie with other previously
studied hashtags. As also discussed in the Literature Review
section, Bruns and Stieglitz observed the emergence of two
clearly distinct clusters: media events (e.g. #royalwedding,
#eurovision) and crisis/emergency events (e.g. #tsunami,
#qldflood, #londondriots). In the former case, original tweets are
common and URLs are mainly used to share further stories about
the media events at hand. In the latter case, during an urgent
situation, it is more important to share vital information such as
emergency numbers; hence, a characteristically high proportion
of retweets and URLs were observed. When mapped on the same
chart, the case of #JeNeSuisPasCharlie is noticeably closer to the
second cluster characterised by more retweets and more
inclusions of URLs (Figure 2).
!
In the aftermath of the shooting, many well-known cartoonists
expressed their condolences and solidarity for Charlie Hebdo by
displaying tribute drawings [
        <xref ref-type="bibr" rid="ref21">20</xref>
        ]. Two of the most frequently shared
tweets in our dataset also contained links to drawings, but in this
case one by the Arab Brazilian freelance political cartoonist Carlos
Latuff and another by the Maltese–American cartoonist and
journalist Joe Sacco. The two drawings represented a take on the
incident that was different from the one put forward by the
mainstream community of cartoonists in response to the tragedy of
their colleagues at Charlie Hebdo. Both Latuff and Sacco pointed
out that the magazine had been publishing, in the name of the
freedom of speech, images often considered to be offensive for the
Muslim population and that the same concept of freedom of speech
had not been invoked in the case of an anti-Semitic satire earlier. 
Along the same line, another heavily retweeted message recalled
the story of Australian newspaper The Sydney Morning Herald
[
        <xref ref-type="bibr" rid="ref16">15</xref>
        ] being forced to issue an apology and remove a drawing that
was considered anti-Semitic. This tweet also included the hashtag
#JeSuisAhmed, with reference to a Muslim police officer, Ahmed
Merabet, also killed during the Charlie Hebdo attack. Many
Twitter users indeed joined the #JeSuisAhmed hashtag.
According to Topsy, it was used over 150,000 times in the days
following the attack in a show of condolences for all victims of
the shooting.
      </p>
      <p>The most frequently shared external sources (URLs) were all
images. Links pointing to news sites were rare. This is because
#JeNeSuisPasCharlie was not about the news. It’s primarily goal
was instead to mark and declare an identity by distinction. To that
end, 2% of the retrieved tweets were made up of nothing but the
hashtag.</p>
      <p>As mentioned in the previous section, the first tweet with
#JeNeSuisPasCharlie was published less than an hour after what
was reported as the first tweet containing #JeSuisCharlie. While
the hashtag started as an immediate reaction to #JeSuisCharlie,
nevertheless, its nature changed over time.</p>
      <p>The Breakout Detection tool developed by Twitter engineers
helped us identify three moments of higher user engagement
(Table 2). Besides the words related to the most retweeted posts
(such as Latuff’s cartoon and the Sydney Morning Herald case)
discussed above, there are a few noteworthy dynamics in Figure
3. First, the clusters of words including désolé [sorry] (N=388),
familles (N=564), victims (N=628), and compatis [sympathise]
(N=409) were present in the first dendrogram but not in the
following two. Liberté and expression (and their corresponding
English words) were prominent in all three moments, confirming
that the freedom of expression and its contested limits were the
real leitmotif across the entire dataset. Terms such as racism and
racist stood out in the second and third moments since users of
#JeNeSuisPasCharlie started to approach Charlie Hebdo’s satires
from different angles than free speech.</p>
    </sec>
    <sec id="sec-9">
      <title>5.CONCLUSION</title>
      <p>Using a combination of various quantitative techniques, the
present study explored the structure of the discussion around the
#JeNeSuisPasCharlie hashtag. First, the discussion had a high
proportion of retweets (70%) and URLs (41%). Compared to
some previously studied hashtags, #JeNeSuisPasCharlie behaved
more like crisis/emergency hashtags than media spectacle
hashtags. That said, our analytic results also highlighted the
heterogeneity of the viewpoints and arguments aggregated under
the hashtag in question. Users of the said hashtag showed
resistance to the mainstream framing of the Charlie Hebdo
shooting as the universal value of freedom of expression being
threatened by religious intolerance and violence. In this context,
retweeting something that would justify their resistance was a
way of marking their identity as distinct from what was accepted
in the mainstream. Given the sensitivity of the subject, such
retweets also helped the users protect themselves from the risk of
being viewed as endorsing the violence. We also observed a
unique practice of tweeting nothing but the hashtag, amounting to
2% of the dataset. This is a strategy that can be explained in a
similar vein.</p>
      <p>Over time, there were three distinguished phases in the
manifestation of this resistance: Grief (i.e. joining the mourning
for the victims of the attack but indicating a reservation against
the proposed frame); Resistance (i.e. starting to voice out the
resistance); and Alternatives (i.e. fully developing and deploying
alternative frames). In this study, the hashtag was not a
conversation marker as previous studies identified but a
discursive device that facilitated users to form, enhance, and
strategically declare their self-identity.</p>
      <p>Our quantitatively oriented methodology here allowed us to
identify the topical and network structure of the discussion
around #JeNeSuisPasCharlie and its evolution over time. We also
suggest as an avenue for further research to delve more
qualitatively into the ways in which individual users coped with
the sensitive nature of the issue at hand and challenged the
mainstream perspective.
