      <abstract>
        <p>The paper studies the agenda by popular talk shows on TV in Russia over a more than three-years period in 2016-2019. Two major talk shows are considered, namely "Meeting Point" (NTV Channel) and "60 minutes" (Russia 1 Channel). Four long-run topics are considered, which are related to situation in Ukraine, Middle East (civil war in Syria, Russian-Turkey relations etc.), USA (including RussianUS relations), Europe (including EU-Russian relations, the migrant crisis and Brexit). Abstracts of each episode are taken from the broadcasters website as raw data for analysis, the Python code was developed in order to collect them and save in the txt format. Topic-related lists of key words are made to assign one or several topics to each episode. Basing on those lists, one or several topics were assigned to each episode. Making this for each episode of a given week, we obtain weekly scores for each topic; these scores being the numerical measures of the topics' saliency in the shows.</p>

      <title>1. Introduction</title>
      <p>
        The agenda-setting theory by McCombs and Show [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ] has been recognized as one the most
important advances in political communication research. Its central idea is given in short form
by Cohen [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] (quoted from [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]): the press "may not be successful much of the time in telling
people what to think, but it is stunningly successful in telling its readers what to think about".
Accordingly, agenda-setting research is in large part the study of what the mass media talking
about.
      </p>
      <p>Traditionally, the activity of the mass media is associated with telling the news, however,
today we can see the rise of political talk shows on TV in Russia. This trend can be considered
favorable for researchers simply because the whole idea of these shows is to focus on issues
that the audience believes important.</p>
      <p>
        In this paper we study empirically the content of two of the Russian political talk shows,
namely "Meeting Point" and "60 minutes", which are generally known broadcasts with a large
audience. For example, during the week 13 to 19 November 2017, according to Mediascope [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ],
their audiences were as follows:
• "60 minutes": 4.5 rating points, 14.4 share points (14 November).
      </p>

        <title>To our knowledge, there are no studies of agenda by talk shows.</title>

      <title>2. Method</title>
      <sec id="sec-2-1">
        <title>2.1. Method in Brief</title>
        <p>The whole idea of our approach is as follows. We consider four topics that are widely
recognized as main long-run topics of political discourse in Russia, and aim to estimate the
proportion between them as a function of time.</p>
        <p>A topic’s saliency during a given week is characterized by its weekly score that is calculated,
roughly speaking, as the number of episodes of all shows featuring the topic, adjusted to their
duration and number of topics addressed in the episode. Technically, the central point in our
work was the identification of the topic (or several topics) featured in a certain episode. In
order to do that, we collected the abstracts of all episodes of two popular Russian Political Talk
Shows, namely "Meeting Point" and "60 minutes" from more than three-years period. Four
political topics often covered by political talk shows were in the focus. These topics are:
• UKR (Ukraine);
• MES (Middle East: civil war in Syria, Russian-Turkey relations etc.);
• USA (US politics and economy, Russian-US relations, NATO, Global security and relation
between Russia and the West as a whole);
• EUR (European politics and economy, EU-Russian relations, The European migrant
crisis, European Union, Brexit etc.).</p>
        <p>There were, of course, episodes on other topics such as Far East (Russian-China and
RusianJapan relations, economic performance of China etc.), Former Soviet Union states excluding
Ukraine and EU members (their politics, economy, relations with Russia, USA and EU), Russian
economy, Russian elections, conservative vs liberal values, historical legacy and so on. We did
not consider these topics but took the corresponding episodes into account when counting the
proportions of the weekly number of episodes.</p>
        <p>For each of the four topics, the list of key words was made. Using these lists, each episode
of the show was assigned one or several topics (for example, 0.5 UKR and 0.5 USA). After that
the proportions of each topic in all episodes of the week were calculated.</p>
        <p>Bearing in mind the perspective of studying the process of agenda-setting by these shows, we
weighted diferent shows according to their typical duration thus getting the score of each topic
in each show for each week. For instance, an episode of "Meeting Point" last somewhat longer
that that of "60 Minutes", therefore their duration-related weights are 5 and 4, respectively.
That is, the score of a topic in "Meeting Point" is its proportion multiplied by 5. The total score
of a topic across all shows is the average of its show-specific scores. This total score reflects
the proportion of the topic in media agenda.</p>
        <p>The future plan is to compare dynamics of proportions with public attention to topics thus
identifying the agenda-setting role of political talk shows.</p>
      </sec>
      <sec id="sec-2-2">
        <title>2.2. Data Collection</title>
        <p>Two generally known daily talk shows were considered, namely "60 minutes" (Russia 1
Channel) and "Meeting Point" (NTV Channel). Brief description of each episode of each show is
available on the TV broadcaster’s website. For both show, description of an episode typically
has about 40 words (with nearly all descriptions falling between 25 and 60 words). An original
Python code was developed in order to collect them and save in the txt format.</p>
        <p>The collected data encompass the period of time from the first episode of each show (29
February 2016 for "Meeting Point" and 12 September 2016 for "60 minutes") to 18 April 2019.</p>
        <p>These texts were used as raw data for the analysis.</p>

          <title>First, we assign each show a duration-related coeficient</title>
          <p>= 5.</p>
          <p>
            The topic score for each episode was assigned basing on the following algorithm. For each
of the four topics specified above a list of keywords was developed. The English translation
is given below. It should be noted that this English list should not be understood literally,
because the correspondence between Russian and English words is not perfectly one-to-one.
For example, the English word "Chinese" is translated into Russian diferently in cases when it
stands for a Chinese man and when it is an adjective (say, Chinese smartphone).

Stoltenberg, START (note: the corresponding Russian abbreviation does not coincide
with a common word), Missile Defense, inference + election, Skripal, neoconservatives,
Assange, Venezuela, Congress, PMCs, Guantanamo, sanctions, transatlantic,
disarmament, arms race.

morphological analyzer "pymorphy2" [
            <xref ref-type="bibr" rid="ref4">4</xref>
            ]), the we count the keywords from each of the topics’
list, taking into account the following points.
          </p>
          <p>First, it should be borne in mind that some of "keywords" are actually combinations of two
consecutive words. For example, words "party" and "region" can appear in many contexts, but
we count a keyword only if the appear in a row to form the phrase "Party of Regions", which
clearly refers to the UKR topic.</p>
          <p>Similarly, the words "Minsk", "agreement" and "process" are not keywords by themselves,
however the phrases "Minsk Agreements" and "Minsk Process" also refer to the topic UKR.</p>
          <p>If an abstract contains the words "Return + sailors" (not necessarily in a row, as in "return
sailors home" or "return Russian citizens in exchange for Ukrainian sailors"), then we counted
it in the topic UKR.</p>
          <p>Having counted the keywords in the abstract, we can assign one or several topics to it. If
all the keywords refer to a single topic, then we assign this topic to the abstract (that is, to the
episode). If there are keywords from the several topics, we use the following algorithm.</p>
          <p>Suppose  &gt;</p>
          <p>1 topics were addressed in the abstract. Denote by   ,  = 1, ...,  the number of
keywords for the topic  .</p>
          <p>If all   ≤ 1,  = 1, ...,</p>
          <p>, then put   =   for  = 1, ...,  .</p>
          <p>If there is at least one   &gt; 1, then for each  , put   =  
if   &gt; 1, otherwise   = 0.</p>
          <p>The score   for topic  is calculated as   =  ℎ   / ∑   ,  = 1, ...,  .</p>
          <p>That is, if there is more than one keyword from one1 topic, and exactly one keyword from
another topic, then the second topic’s score is zero. If there are more than one word from
several topics, then the score is divided between these topics proportionally to the number of
words. If no topic has more than one keyword, and several topics have exactly one keyword,

then the score is divided between then equally.</p>
          <p>Thus, each episode is assigned topic scores. Topic score for a week is the sum of topic scores
for all episodes of the week.</p>
        </sec>

      <title>3. Results</title>
      <p>Some descriptive statistics are shown in Tables 1, 2. The diference between them is that the
latter presents the number of episodes that added to the scores. For example, UKR topic was
touched upon in 347 episodes of "Meeting Point", from which 290 added to the score of this
topic. In other words, there are 57 abstracts with one keyword from UKR topic and more than
one keywords from another topic.</p>
      <p>It can be easily seen that the agenda was dominated by USA and UKR topics, and "Meeting
Point" paid significant attention to EUR topic as well.</p>
      <p>In Figures 1-4 we present the weekly scores for these two topics starting from 12 September
2016, when the first episode of "60 minutes" was broadcasted. From that day to 24 August
2017 this show had one episode in a day, and from 28 August 2017 there are two episodes.
Accordingly, graphs for the two periods of time are presented separately.</p>
      <p>We believe the findings to be applicable to studying agenda-setting function of political talk
shows and estimating the influence of these shows on public attention to certain topics and,
more broadly, on public opinion.</p>

      <title>4. Discussion</title>
      <p>
        The previous Section shows how proportion of each topic in the agenda can be estimated.
The important application is the study of propaganda battles which have recently started to
implement some ideas of the agenda-setting theory [
        <xref ref-type="bibr" rid="ref5 ref6">5, 6</xref>
        ].
      </p>
      <p>
        Still, models of rumors, information influence and information warfare predominantly focus
on other aspects, such as network efects [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] or opinion dynamics [
        <xref ref-type="bibr" rid="ref8 ref9">8, 9, 10</xref>
        ].
      </p>
      <p>Some models emphasize the coaction of mass media and interpersonal communications in
spread of information [11, 12, 13].</p>
      <p>There is also a wide range of related empirical studies including analysis of search queries
[14, 15, 16, 17].</p>
      <p>The growing volume of literature, however, keeps dealing with a single-topic situation. Thus,
the area of information battles with multicomponent agenda remains underresearched.</p>
