      <abstract>
        <p>Widely employed digital archives of literary works are not necessarily neutral sources of knowledge, but rather literature ecosystems where the relevance of authors and works are shaped by communities of users. This could afect the visibility of authors belonging to historically marginalized groups of people, as it has been demonstrated by previous works on the under-representation of non-Western writers. In this work, we present an exploratory analysis on how divergent representations of works written by African and Asian writers emerge from diferent platforms. More specifically, we compare the reviews gathered from an Italian and an international social networks of readers, in order to highlight how authors from these continents are perceived by two diferent communities of users.</p>

      <title>2. The Under-Represented Writers Knowledge Graph</title>
      <p>
        Several digital resources providing information about literary works and authors are available
online, created with diferent scopes and purposes. Some of them are general-purpose archives
that host user-generated contents, while some others are the outcome of monographic researches
curated by Digital Humanities scholars. Example of the former type are websites like Goodreads,
owned by Amazon, LibraryThing, owned by AbeBooks, and Anobii, owned by the Italian
publisher Mondadori, namely, social networks where users share their reads and review books.
A project of the Internet Archive Foundation, Open Library is an online service for book loan
where users can have an active role by adding and editing records in the archive and reviewing
books. Wikidata is a Knowledge Graph linked to Wikipedia, which has a section devoted to
literary works. Monographic platforms focus on specific literary genres across countries and
ages. It is the case of The European Literary Text Collection1 [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ], a multi-lingual dataset of
novels written from 1848 to 1920, DraCor2 [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ], a collection of plays in multiple languages, and
MiMoText3, a corpus of French and German novels published from 1750 to 1799.
      </p>
      <p>
        The Under-Represented Writers Knowledge Graph (URW-KG)4, a dataset of writers and their
works [
        <xref ref-type="bibr" rid="ref1 ref9">1, 9</xref>
        ], has been created with the specific goal of studying and reducing
underrepresentation. Defining underrepresentation is a hard task, as it may bring with it arbitrary distinctions
and the use of inadequate terms. To provide an objective and clear definition, we adopted
the term ‘Transnational’, which refers to people who “operated outside their own nation’s
boundaries, or negotiated with them” [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ]. This definition focuses on the relation between a
person and their country of birth, based on two axes: (i) being born in a former colony country,
which follows the post-colonial theories [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]; (ii) belonging to an ethnic minorities in a Western
country.5.
      </p>
      <p>
        Our resource is built upon the Under-Represented (UR) Ontology Network, which organizes
knowledge about authors and their works and aligns information gathered from diferent
sources. The Ontology Network is composed of two main modules: the Under-Represented
Writers Ontology (URW-O) [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]6 and the Under-Represented Books Ontology (URB-O)7. The
URW Ontology (URW-O), which represents biographical knowledge about writers, gathers
biographical information into a dul:Situation patterns [
        <xref ref-type="bibr" rid="ref12">12</xref>
        ], which is the setting for the author,

their role and the other spatial and temporal information (eg: dul:TimeInterval, dul:Place) [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ].
The URB Ontology (URB-O) inherits the representation of works and editions from FRBR [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ]
and FaBiO [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ], designed for guiding the cataloguing of works according to Semantic Web
principles. The PROV Ontology [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ] is used to model the attribution of a book to their author
(prov:wasAttributedTo), and to make explicit the source of knowledge from which an information
is sourced (prov:wasDerivedFrom).

      <title>3. A Quantitative Assessment of Underrepresentation</title>
      <p>Building the URW-KG was a two-step process. We first gathered from Wikidata all the entities
of type Person (wd:Q5) with occupation (wdt:P106) writer (wd:Q36180), novelist (wd:Q6625963),
or poet (wd:Q49757). Consistently with the definition of underrepresentation provided above,
we filtered out all the people born before 1808, which marks the beginning of the
SpanishAmerican conflict – considered as the first process of decolonization. After this first step, we
obtained a KG of 194, 065 authors and 145, 375 works, that allowed us to identify a significant
underrepresentation of Transnational Writers. In fact, they are only 17, 368 on Wikidata, the
9%, and the number of their works is even more represented, since they are only the 8, 380
(5.7%).</p>
      <p>In order to understand if such underrepresentation is specific to Wikidata or if is shared by
other archives, we integrated into the knowledge graph three external sources of knowledge
specialized in archiving books: OpenLibrary8, Goodreads9, and Google Books10. For this
integration, we considered the writers obtained from Wikidata as a constant, and gathered all
their works from Open Library and Goodreads: by doing so, we could assess the diference in
the number of works on Wikidata and on the external resources.</p>
      <p>The first part of the data integration strategy consisted in collecting writers’ ids from
OpenLibrary and Goodreads. We first considered all the 55, 834 authors with an OpenLibrary id,
retrieving all their works and editions; we thus obtained 891, 037 works and 1, 742, 252 editions.
Results include a set of useful information, including language, publisher, synopsis, subjects,
year of publishing, place of publishing, and ISBN. Then, in order to bypass the limitations posed
by the lack of APIs from Goodreads, we scraped from Goodreads all the 9, 963 writers who do
not have an OpenLibrary id (instead of considering all authors with a Goodreads identifier).
Finally, using the Google Books API, we retrieved from Google Books additional information
about the collected works through their ISBN. By doing so, 1, 177, 801 new items were obtained
and mapped onto OpenLibrary and Goodreads.</p>
      <p>The impact of the data integration strategy is presented in in Table 1. As it can be observed,
the mapping resulted in a significant and general increase of information about writers literary
production. The number of works rose from 145, 375 to 1, 371, 326 (8 times more), and
information about them grew accordingly: there are 20 times more blurbs and 34 more subjects. The
mapping did not only generically increased the number of works and all the correlated
information, but also contributed in rebalancing the proportion between Western and Transnational

10https://books.google.com/
works. The former, which are only the 5.7% on Wikidata, become the 10.1% in the KG after
the integration.</p>
    </sec>
    <sec id="sec-4">
      <title>4. Comparing Social Networks of Readers</title>
      <p>The mappings between Wikidata and external resources showed that the role of communities of
contributors can be crucial in reducing (or spreading) under-representation: platforms based on
diferent groups of users result in diferent representations of World Literature. In this section,
we deepen this intuition by providing a comparative analysis between two social networks of
readers, in order to understand how and to which extent readers from diferent digital platforms
discuss about Transnational writers.</p>
      <sec id="sec-4-1">
        <title>4.1. Data Gathering and Processing</title>
        <p>For our investigation, we chose two platforms where users can upload, review, and discover
books: LibraryThing11, which is composed of English readers, and Anobii12, a website owned
by the Italian publisher Mondadori and thus having a prominent audience of Italian people.
Such a choice paves the way not only for a generic comparison between two website, but may
also provide insights about the diferent attitudes about books and writers from a local and an
international community of people.</p>
        <p>
          Given the high number of writers in our KG, the absence of APIs for gathering data from
Anobii and LibraryThing, and the lack of a structural mapping of authors with these archives,
we performed an analysis of a subset of writers. We selected a sample of the Transnational
writers who have the highest number of editions on Open Library (the topmost 20 born in
Africa, and the topmost 20 born in Asia), and manually found their personal pages on the two
platforms. We then gathered all their works and readers’ reviews. The number of reviews from
LibraryThing is 16, 758, while reviews gathered from Anobii are 12, 141. For each review we
computed the Sentiment score with existing tools that reached the State of the Art for Italian
[
          <xref ref-type="bibr" rid="ref16">16</xref>
          ] and English [
          <xref ref-type="bibr" rid="ref17">17</xref>
          ] Sentiment Analysis. Both tools give as output a label (positive or negative)
and a score in the range 0 − 1. Scores of all reviews labeled as ‘negative’ were converted to
11https://www.librarything.com/
12https://www.anobii.com/
negative values. Finally, we computed the average sentiment of reviews for each author. Table
2 shows results about African writers, while Table 3 shows result for Asian authors.
        </p>
      </sec>
      <sec id="sec-4-2">
        <title>4.2. Quantitative Analysis of the Reviews</title>
        <p>First of all, a diferent distribution of writers by continent can be observed in the two
communities. Reviews about African authors are the 70.5% on LibraryThing, but only the 53.6% on
Anobii. Diferences between the number of reviews on LibraryThing and on Anobii may be
also be observed at a fine grained level. Figure 1 shows the 10 authors with the highest delta
between the number of reviews on LibraryThing and Anobii. Such diferences may be a signal
of the impact of certain authors in a local market like Italy (e.g., Tahar Ben Jelloun), compared
to international trends. In this sense, widening the scope of the analysis by augmenting the
number of digital archives from diferent countries may brings light on which representations
of “literatures” emerge from readers at global and local contexts (see [18] for a similar approach
to Wikipedia).</p>
        <p>Secondly, it is worth mentioning that readers from LibraryThing and Anobii seem to show
more interest for authors of Western origin, even when they are not born in Western countries.
As it can be observed from the data in Tables 2 and 3, 15 out of 20 African-born authors
are children of European or American parents, or belong to white minorities. The number of
reviews increases this gap, since the 91.4% of reviews are about European or American descents.
Proportion are inverted for Asian-born authors: only the 25% of them have European origins
(however, the 42% of reviews are about them). This fact highlights the vulnerabilities of the
criteria upon which the distinction between Transnational and Western writers is drawn (see
Section 2), which should be integrated with other features.</p>
      </sec>
      <sec id="sec-4-3">
        <title>4.3. Sentiment Analysis of the Reviews</title>
        <p>
          The two tools adopted for detecting the sentiment of reviews [
          <xref ref-type="bibr" rid="ref16">19, 16</xref>
          ] are both based on a
BERT-based Language Model13. However, since they are trained on diferent languages, they
may provide as output slightly diferent scores. As a matter of fact, a brief look at columns 4
and 6 of Tables 2 and 3 shows that the tool for Italian language is more skewed over negative
and lower values. For this reason, a general comparison of aggregated scores across platforms
is not useful.
        </p>
        <p>The Sentiment Analysis of reviews of books of African writers (Table 2) seems to be consistent
with diferences emerged from the quantitative analysis. Except from J. M. Coetzee, who
obtained the most negative sentiment score both on Anobii and on LibraryThing, readers
opinions significantly difer. Simon Scarrow, namely the first ranked author for sentiment with
a score of 0.681 on LibraryThing, is only ranked 8ℎ on Anobii. On the contrary, Wole Soynka
obtained a score of 0.600 on Anobii while on LibraryThing he is only 16ℎ. Other significant
diferences regard Chinua Achebe, Nadine Gordimer, and Tahar Ben Jelloun, who respectively
obtain a score of 0.401, 0.304, and 0.494 on LibraryThing against the following negative values
on Anobii: − 0.169, − 0.100, and − 0.194.</p>
        <p>The trend of readers’ sentiment about Asian writers (Table 3) is not as simple to interpret
as the previous one. This is probably due to the lowest number of reviews per author who
may have had an impact on the average scores. Many authors receive comparable scores. Eg:
13Bidirectional Encoder Representations from Transformers: https://github.com/google-research/bert
Rajneesh (0.637 vs 0.563), Deepak Chopra (0.461 vs 0.420), and Stephanie Laurens (0.320 vs
0.381). Anita Ganeri, namely the author who receives the highest sentiment on Anobii (0.666)
is also the 2 ranked on LibraryThing, while Sri Chinmoy (0.949) and Solomon Volkov (0.008)
are respectively the author with the best and the worst scores on LibraryThing, but these results
are not comparable with Anobii, since an adequate number of reviews from this platform is
missing. In general, readers’ sentiment seem less controversial between the two platforms
for Asian authors: the only two examples of high divergence are Amin Maalouf (0.702 on
LibraryThing; 0.186 on Anobii) and Vandana Shiva, who obtained the lowest sentiment on
Anobii with − 0.632 while on the LibraryThing it scored 0.437.</p>

    <sec id="sec-5">
      <title>5. Conclusion and Future Work</title>
      <p>In this paper, we presented a quantitative analysis of readers’ reviews about Asian and African
writers on Anobii and LibraryThing. The analysis shows that diferences emerge in the reception
of authors on the two platforms, both quantitatively and in the term of the sentiment expressed
by reviews. Such diferences may be interpreted as country-specific, since Anobii is mainly
frequented by Italian readers while LibraryThing is more international. However, a common
aspect between the two communities of readers is that they both give more attention to
Africanborn and Asian-born writers with Western origins. Future work will be devoted to widening the
analysis with a higher number of platforms and writers, in order to provide tools and resources
for exploring country-specific receptions of literary works.
