      <title>Introduction</title>
      <p>
        Nowadays, the definition of discourse is trendy because of frequent usage in scientific
texts, political speeches, debates. Reference to opportunities that let artificial
intelligence in all spheres, including discourse analysis, develop is extremely significant.
However, understanding the discourse is a complicated thing due to the fact that, on
the one hand, the definition is blurry, on the other hand, has a narrow, more accurate
meaning depending on context. There is no common opinion on discourse and the
way to analyze it because of a good quantity of various approaches where we can see
a competition while determining discourse and discourse analysis [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. The discourse
is a difficult and multidimensional phenomenon that should be considered from
different theoretical points of view.
      </p>
      <p>
        The approach to discourse as communicative act and communicative event is
demonstrated by linguist T. Van Dijk. The scientist claims that discourse is
complicated unity of language form, meaning and acting that corresponds to the definition of
communicative event [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. In his point of view, discourse as a complex communicative
phenomenon comprises social context. The notions of scientist have a huge sense for
understanding a correlation of discourse with political sphere.
      </p>
      <p>Due to unlimited and pervasive character of informational pluralism, expression of
citizens’ opinion on different online platforms, argumentation of positions can be
considered as social practices of public civil dialogue and interaction, realized in
online environment.</p>
      <p>
        Based on diverse approaches to studying political discourse [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ], it can be
researched not only as information and communication and psychological and political
phenomenon, but political sphere, containing opportunities for multilateral and
multifunctional public dialogue and interaction. The political discourse as applied category
can be a resource and instrument of public speech integration because it provides with
contacts and socio-political actions, including participance of citizens and their
involvement in authority.
      </p>
      <p>
        Political online discourse is simultaneously an electronic political environment and
electronic political life of person who can act as anonymously as openly [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. We
consider political Internet discourse (online discourse, electronic discourse) as one of the
PR instruments in political and governmental spheres. Political online discourse can
form and reflect moods, citizens’ opinions with aim of influence on making political
decisions, management of governmental affairs, regulation of society, manipulation,
pressure on government and etc.
      </p>
      <p>Therefore, for government it is important to manage to analyze Internet discourse
competently. To do this, special methods, generated with usage of the most modern
technologies, are required. One of authors’ method of discourse analysis, based on
manual data processing and with incorporation of machine training will be
represented in the article.

    <sec id="sec-2">
      <title>Problem statement</title>
      <p>Internet discussions on various socio-political themes are currently becoming more
relevant for researchers due to the fact that online deliberations more focus on critical
discussion and reasoning of communicators' views on acute public issues. Therefore,
the value of deliberations is that their participants can articulate their interests, openly
express their positions and support them with significant arguments.</p>
      <p>Subsequent paragraphs, however, are indented. In fact, online deliberations
contribute to the development of democratic communication as they allow participants to
demonstrate their political creativity, openly argue about serious political themes,
lobby their interests without mediators. Thanks to exchange of views, positions on
different social and political matters a public dialogue between government and
society which is aimed at addressing certain problems, where citizens actively take part.</p>
      <p>Studying Internet discourse is a methodologically and empirically difficult task
because of restrictions, existing in scientific sphere, and lack of grounded theoretical
and analytical works, dedicated to discourse analysis and representation of results.
Hence, it leads to wide and various interpretations of empirical evidence among
investigators, experts and participants of deliberative online process. The concept of
deliberation, explicitly developed in the theory of communication ethics of J.
Habermas is habitually considered as an everyday practice of political online discussions
that emerges due to any actions and processes in the political sphere either on local,
national or global levels. However, some difficulties, connecting with research
methodology of online discourse, exist due to a few reasons.</p>
      <p>First of all, the majority of virtual public sphere researches have not been
materialized yet in analytical tools that would let empirically study discursive citizens’
practices. In other words, the problem is that how to convert normative values of public
sphere and discursive ethical theories into studying discursive processes.</p>
      <p>Secondly, efficiency of concrete research methodology for collection of empirical
data depends on its ability to take account of role of technological and constructive
characteristics that allow online discourses to function. The absence of delimitation
between technological and social characteristics of web spaces can lead to less
reliable evidence and contradictory interpretations of discourses.</p>
      <p>Moreover, the comprehension of discussion as a talk only about problems, not
actions, means that efficiency of political participation is equal to zero because
participation must be a politically motivated civil action. Such a narrow interpretation of
public sphere is one of the point which does not let investigations show convincing
evidence of pragmatic usefulness of online public sphere.</p>
      <p>The majority of mass communications’ investigations still focuses on audiences,
addressers and recipients that cannot be adequately used for new digital communities
and their discourses. In the era of e-communications mass media has lost the
monopoly on public informing. The absence of innovations in researches of public Internet
discussions is one of the basic reason of existing ambiguity and radically opposite
views on communicative practices on Internet.

      <title>Research methodology</title>
      <p>
        Selecting the methodology of Internet discourse analysis, we decided to point out the
methodology of discourse analysis, created and described by Yu. Misnikov in his
PhD-thesis. The scientist has generated «deliberative standard to assess discourse
quality» [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ], where seven thematically different discursive parameters of the
deliberative standard, corresponding to specific research issues and using for guiding the
process of encoding messages of Internet discussions, are described. It is important to
note that Yu. Misnikov was the first investigator to do this, since there were no direct
analogues in the scientific literature at the time of his dissertations’ publication. Each
parameter of standard contains a set of specific empirical characteristics, intended to
reflect certain discursive qualities.
      </p>
      <p>The first parameter correlates with participatory equality and posting activism and
contains seven characteristics: participant ID, participant username and membership
status, post ID, participant post ID, post total ID and posting date. While investigating
level of civil activity we have frequently come across to problem, connecting with
unequal distribution of participation in discussions. In addition, predominance of
highly interactive, strongly personalized and frequently impolite features in Internet
deliberations result in their weak, low and inadequate quality.</p>
      <p>
        The second parameter reveals civility which is used for characterization of
qualitative character of public online discussions and connected with demonstration of
tolerant attitude [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. The civility data are not easy to interpret because of lack of universal
approach, letting do it. There can be some situations when messages contain polite
and impolite speech aspects at the same time. As a result, it causes difficulties in post
coding. Besides the usage of rude expressions that explicitly illustrate intentional
incivility, some messages can only imply unpleasant under-lying theme. In some
cases a response of online discussions’ subjects to such posts can be a reliable indicator,
reflecting all the complexity of subjective relations that are formed between
participants in the process of discussion. If we speak about polite messages, they can have a
special objective. For example, such comments can be addressed to certain users in
more personalized manner or with emphasis on a few aspects of topic that contributes
to more involving of people in deliberation
      </p>
      <p>1) civil (this kind of messages can be expressly polite or friendly welcoming, not
necessarily supportive or critical);</p>
      <p>2) normal (these messages are ambivalent or neutral, can be both critical and
supportive);</p>
      <p>3) uncivil (these messages contain expressly rude, derogatory or unfriendly,
offensive or hostile moments, not necessarily critical, can be supportive);
4) other (hard to qualify because there can be different types of civility).</p>
      <p>The following parameter is validity claim-making and consensual practices that
includes propositional truth (objective world), normative rightness (common
intersubjective worlds), subjective truthfulness (personal worlds), agreement (acceptance,
approval, praise, positive, assent), disagreement (rejection, opposition, criticism,
negative, dissent). We consider one more parameter: intent of speech acts that can be
directive (direct, without any dispute and choice), commissive (there can be some
corrections), expressive (predominantly emotional character).</p>
      <p>The relevant constituents of discussions are such parameters as discursive
interactivity and dialogism, covering personally addressed, including use of ad-dressed
names, to authors of seed post, 2 preceding posts or 10 preceding posts; impersonally
addressed posts; direct references to other participants (including quotes); explicit
responses (feedback) to other messages; quotation of seed post, 2 preceding posts or
10 preceding posts.</p>
      <p>Dialogism conceptually emphasizes on environment and its external conditions. If
a communicator has a comprehension of them and knows how to find a necessary
approach to other people, he will understand himself and his communicative actions
much better. However, there is a complication when self-realization and
selfexpression are through others. Our speech acts cannot be determined as original or
terminal because they all have a preliminary history and simultaneously contain a
presentiment, connecting with reactions of others on what was said or written. The
dialogue is a recognition of needs and interests of others through reciprocity that
includes not only agreements, but oppositions and contradictions as well.</p>
      <p>The definition of interactivity is so close to «dialogism». Interactivity is commonly
thought as a key to studying of public online discourses. In fact, it is not required for
participants who are involved in public dialogue to face each other personally, they
can interact remotely. Therefore, it is one of advantages of interactivity. In addition,
discursive interactivity can give communicators a possibility to be dialogic and
cooperative with people who have equal statuses. As a consequence, this encourages other
citizens to participate in online discourse. Disagreements, polemics are considered as
a part of interactivity as well. There is a dispute about participants and their
possibilities to be interactive. Some re-searchers claim that interactive participants are those
who answer a previous message whereas others reckon that interactive participants try
to give a response almost to all messages. From our personal angel, these two
categories characterize participants as interactive ones, but the extent of their interactivity
will differ noticeably.</p>
      <p>Argumentation as an overriding parameter is variable and never static, it is
primarily aimed at ensuring understanding between the participants in the discussions and
maintaining a dialogue between them during interactions. The arguments are always
important as they assist to see positions of consent and disagreement, which, in turn,
can be democratic forms of public reasoning through interpersonal interaction.</p>
      <p>
        The argumentation is an act of relative comprehension between communicators
and mutual acknowledgement of other individuals and their points of views.
Correspondingly, when commentators give arguments on the basis of reciprocity, their
communication becomes more discursive. The quality of argumentation depends on
relations between people who speak and listen because there is no sense when there is
no constructive dialogue. The communication is considered as a relevant instrument
when community reacts and gives a response to socially or politically important
questions. Otherwise, a communicative act is useless and insensitive. Isolated discourses
almost have no sense for being analyzed, particularly in polarized socio-political
relations since their participants are not enough represented as rhetorically persuasive and
dialogically adaptive [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ].
      </p>
      <p>Argumentation includes three directions: facts, numerical data, statistics,
conclusions, comparisons, logical inferences, generalizations, examples, other evidence
presented to prove or disprove opinions; references to online resources (within and
outside thread, forum); references to print and broadcast media.</p>
      <p>The final parameter is thematic diversity. The themes of discussions can be
correlated with state and government, society and politics, economy, social problems,
Russian regions, foreign relations (ex-USSR), foreign relations (overseas), culture and
lifestyle, media and Internet.</p>
      <p>
        The methodology of discursive analysis, based on the concept of Habermas and
developing it (Habermas never counted results), was chosen due to some reasons [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ].
First of all, we study online discourse from positions of political public relations, and
a communicative aspect of discussions that we can investigate thanks to selected
approach is important to us. The certain aspects of studying deliberations
(argumentation, interactivity, dialogism, activity of participants, rationality, civility and etc.)
aiding to describe a discussion, its members, and identify civil positions and their
content were marked by scientists.
      </p>
      <p>Secondly, the procedure is clear and simple, there is no problem to make use of it
by Excel program. When we research users’ comments from Internet debates we give
a three-unit code to each comment. As a result, it assists to determine a row of posts
in chronological order and their authors, and also allows to see a quantity of posts that
were made by the same author. Hence, these characteristics can be used during
counting a number of posts and their producers. When it is about detecting the aspects of
online discussions mentioned above, there is a special method to note a position. If
there is something that we aim to investigate (for example, theme, content, comment,
argumentation extent and etc.), we fix a position by writing «1» in space of program
Excel. If there is nothing necessary, a space in Excel is empty. Making up overall
conclusions, a general quantity of registered positions is counted and significant
inferences are indicated.</p>
      <p>Thirdly, hand-operated data estimation and their coding can be brought to machine
training that, undoubtedly, will accelerate and facilitate a work of researchers.
However, this is not so easy. It is necessary to train a computer program to process
information correctly by giving a certain number of comments. In accordance with our
data, it should be at least 10000 posts for machine training. For hand-operated
analysis one hundred posts in each discussion is enough.

      <title>Internet discourse</title>
      <p>AI (Artificial Intelligence) includes a whole range of rapidly developing technologies
and processes. A special place in terms of relevance for public administration is
occupied by Machine Learning. Machine Learning (ML) is usually defined as a class of AI
methods that study and develop algorithms for automated pattern recognition and
knowledge extraction from a huge amount of data, as well as training-based hardware
systems based on the data obtained, generating predictive values and
recommendations.</p>
      <p>Machine Learning combines such disciplines as mathematical statistics, methods
optimization, information retrieval, data mining etc. Research in the field of ML
necessarily involves model experiments on test or real data in order to verify the
relevance and quality of methods, confirm hypotheses, calculate statistical and empirical
metrics, and create a criteria list that have statistical significance. According to our
case it is necessary to "train" models by providing a certain number of posts,
comments, and online discussions, previously marked up into categories (topics) by a
group of experts or coders.</p>
      <p>
        The main methods of ML are linear and logistic regression, support vector
machines (SVM), decision trees, random forest, gradient boosting, neural networks, deep
learning, self-organizing maps etc. [
        <xref ref-type="bibr" rid="ref10 ref8 ref9">8–10</xref>
        ].
      </p>
      <p>Artificial neural networks are ones of widely used Machine Learning methods.
Neural networks are considered the most effective tools for solving problems of
classification, pattern recognition, predicting the behavior of complex systems. The
process of creating and training a neural network is iterative, which allows us to achieve
the desired precision and configure the created model quite flexibly. Training a neural
network involves a process in which the parameters of a neural network are
configured through modeling the environment in which the network is embedded. There are
usually three ways for doing that: supervised learning, unsupervised learning, and
reinforcement learning.</p>
      <p>
        Natural Language Processing (NLP) is used in combination with ML methods
because it allows us to identify dialogic acts and speech, detect emotions, analyze the
sentiment of text etc. By NLP methods natural language is converted into a format
used by Machine Learning methods to implement and augment their own algorithms.
The main methods and approaches for NLP are tokenization, stop-words list
elimination, stemming, lemmatization, Named Entity Recognition, Bag-of-words model,
TFIDF function, Word2Vec and Doc2Vec technics etc. [
        <xref ref-type="bibr" rid="ref11 ref12 ref13 ref14 ref15">11–15</xref>
        ].
      </p>
      <p>
        Conceptually usage of main AI tools for discourse formation model, which is
based on theories of J. Habermas and is developed by Yu. Misnikov [
        <xref ref-type="bibr" rid="ref16">16</xref>
        ], is presented
on the Fig.1.
      </p>
      <p>
        We can mention our own experiment in 2019 as an example of using ML
possibilities to conduct research on Internet discourse. The experiment was related to deep
learning in the text classification field. As a result, our network model learned to
predict the position of participants ("for", "against" or "neutral") in discussions in relation
to such a hyped socio-political topic as the Russian pension reform. An automated
tool was developed for the study of Internet discourses based on recurrent neural
networks with an LSTM block (RNN+LSTM). For binary classification ("for" and
"against") the accuracy rate was 89%. For triple classification ("for", "against",
"neutral") the accuracy rate was 78%. Gained result were quite good and that fact
prompted us to continue research in that area. For the more detailed description of
experiment, see [
        <xref ref-type="bibr" rid="ref16 ref17">16, 17</xref>
        ].
      </p>
      <p>The made experiment showed that ML is a reliable and easy-to-use tool for
analyzing the content of discussions on the Internet and understanding their intended
meaning in semantic terms. Research in this area needs to continue to offer solutions for
the use of AI to better understand the results of any public discussions. Many new
research questions have risen. For instance:
1) Is it possible to identify the process of social construction and generation of
social meanings?</p>
      <p>2) Is it possible to generalize ordinary conversations on the Internet so that the
process of forming such socio-political meanings becomes clearer?</p>
      <p>The answers to these questions can help researchers not only to better understand
the social dynamics of the modern digital society, but also to improve the quality of
citizen participation in politics and create new tools to facilitate such participation.</p>
      <p>There are also several prospects for further research:
1) The first one is to use ML and other AI technologies as research tools for
encoding and analyzing parameters of the deliberative standard described in the article.</p>
      <p>2) The second one is related to the creation of methods for recognizing parameters
such as argumentation and civility. For example, the identification of argumentation
and some of its types (e.g. links to sources, citations) will be based on parsing and
using regular expressions to search for links using ML to improve search accuracy.
The selection of civility types can be done automatically, which is quite like the
sentiment analysis, but there is a slightly different approach.</p>
      <p>3) The third one is to provide researchers with statistical analysis based on ML
results with visualization elements, for example, types of civility by city and their
classification on a map. The results can be displayed in a table as well as presented on a
graph or on a diagram. These outcomes for instance can be helpful for the city
administration that can consider citizens’ opinion about some urban objects or useful for
business field to know customers’ feedbacks.</p>
    </sec>
    <sec id="sec-6">
      <title>Conclusions</title>
      <p>Thus, the presented method of discourse analysis can be gradually translated into a
machine (computer) format and implemented using the power of AI.</p>
      <p>For text analysis on Internet there are a wide range of tools of Natural Language
Processing methods such as Word2Vec and Doc2Vec, TF-IDF, bag-of-words,
lemmatization, stemming, stop-words removing and so on. It is expected that the proposed
solutions for the use of AI and ML will contribute to a deeper understanding of the
results of any public discussions.</p>
      <p>The design and prototype development of an application will also allow to arise the
content analysis of public discussions to a qualitatively new level and help
participants to assist in Internet discussions by smoothing out contradictions by using
welltrained neural networks. Targeted on-demand discussions are assumed to be in a case
when participants understand and consciously accept the role of such an application
as a discussion assistant. Such an app should work on different platforms, including
social networks and discussion forums.</p>
