        <p>This paper presents a case study about the responsible design of a recommender system of a prominent Dutch Public Service Media (PSM) organization, combining personalized content recommendations to users while aligning with the organization's overarching mission of fostering diversity. A conceptual framework of diversity in news recommenders was translated into four possible prototypes of recommender systems, representing different ways to strike a balance between the objectives of personalization and diversity. These prototypes were presented to PSM stakeholders with different expertise, aiming to increase their insight into practical consequences of different conceptual choices, thus facilitating their communication and decision processes.</p>

      <title>1. Introduction</title>
      <p>The media sector is currently undergoing significant transformations due to the rise of
Artificial Intelligence (AI), which is increasingly playing a pivotal role in creating and
distributing media content [5]. Despite the fact that AI is providing ample room for
innovation, however, it also raises concerns and questions regarding its responsible use [6].
Concerns include, e.g., the dissemination of fake news and misinformation and the resulting
impact on citizenship and democracy, and bias in algorithms, leading to discrimination. To
address these concerns and mitigate negative consequences of AI applications, media
organizations turn to principles, tools and methods of responsible AI [7,10]. However,
though there has been a lot of attention for responsible AI in the last couple of years, much
of this work is rather abstract and theoretical in nature [8].</p>

      <p>
        To move from theoretical contributions about responsible AI towards its practical
application, this paper describes a case study that revolves around the design of a
recommendation system. Recommendation systems are one of the promising and
oftenused applications of AI in the media sector, aiming to connect audiences with a variety of
content based on e.g., their interests, search history, demographics and other contextual
information [9]. Developing a recommendation system in a responsible way, however,
creates a tension between accommodating user needs and interests on the one hand, and
journalistic obligations and public interests on the other hand [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. Particularly Public
Service Media (PSM) organizations, funded by public money, should serve goals such as
informing the public by exposing them to a balanced mix of different views and
perspectives.
      </p>
      <p>
        In the case study, we supported a prominent Dutch PSM organization in developing a
recommender system, which was intended to combine and balance the objectives of
personalization for users and the organization’s mission of fostering diversity. One of the
main challenges the PSM organization faced in developing their recommendation system
was to involve different stakeholders, such as AI developers, UX designers and media
professionals, in this process. Bridging the knowledge disparities among these different
types of expertise is a challenging but necessary step in developing a responsible
recommendation system. In this case study, we used prototypes to explore possible design
directions and to facilitate communication between stakeholders with different expertise
and backgrounds [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. This exploration is particularly significant given that the majority of
existing work in this domain has remained largely theoretical in nature.

      <title>2. Case study: designing four prototypes for diverse recommendation</title>
      <p>This case study was performed in the context of a 2-year research project called DRAMA
(Designing Responsible AI for Media Applications), with a consortium of multiple
universities and media organizations based in The Netherlands. This specific case study
involved a collaboration between one of the universities and one of the (PSM) media
organizations, and was performed in the context of a redesign of the PSM organization’s
website. One of the aims of the redesign was to add personalized recommendation to the
website, while maintaining the organization’s goal to support diversity. At the start of the
redesign project, there was no clear idea on how to balance diversity and personalization
in the recommendation system, and one of the challenges was to include the expertise of
multiple stakeholders in this process.</p>
      <sec id="sec-2-1">
        <title>2.1. Conceptual framework for recommendation</title>
        <p>The conceptual framework we used as a basis for this case study was that of Helberger [4],
further elaborated on in work by Vrijenhoek et al. [11]. The conceptual framework
proposed in this paper consists of the following four models of recommendation, each
promoting different values and goals.
•
•
•
•
•
•
•
•
•</p>
        <p>The liberal model. This model promotes autonomy, self-development and dispersion of
power by facilitating the specialization of a user in an area of his/her choosing and by
tailoring to the user’s preferences.</p>
        <p>The participatory model. This model promotes inclusiveness, participation and active
citizenship by making sure that different users do not necessarily see the same content,
but they do see the same topics. The recommended content’s complexity is tailored to a
user’s preference and capability, and it reflects the prevalent voices in society.
The deliberative model. This model promotes deliberation, tolerance,
open-mindedness and public sphere by focusing on topics that are currently at the center of public
debate, and, within those topics, presenting a plurality of voices and opinions.
The critical model. This model promotes including marginalized voices and defying
prejudices by emphasizing voices from marginalized groups.</p>

        <title>2.2. Metadata available for the recommendation system</title>
        <p>To translate the four conceptual models for recommendation from Helberger [4] into
prototypes for the PSM organization, we organized a session with stakeholders of the PSM
organization to collect the metadata that is available per item that could potentially be
recommended, and to gain understanding in the metadata’s potential relevance for
recommendation. The most important results of the session are summarized below.</p>
        <p>Genre. Examples of genres are human interest, fiction, news and current affairs, sport,
knowledge and education, documentaries, culture and children. This was considered
highly important for personalizing recommendation.</p>
        <p>Content type. Examples of content types are playlist, series, season, promo, trailer, clip,
and broadcast. After some initial discussion, this was considered important for
personalization as well as diversification.</p>
        <p>Broadcaster. In The Netherlands, PSM content is developed by a number of
broadcasters. Each of them has a distinctive societal, cultural or religious identity, e.g., liberal,
right-conservative, left-progressive, equality of opportunity, Christian,
orthodoxprotestant, radical right, and inclusiveness. This was considered highly relevant from a
diversity perspective but less important for users/ user personalization.</p>
        <p>Language. This refers to the language spoken in the content. All non-Dutch content is
subtitled in Dutch. Stakeholders considered this somewhat relevant for diversification,
as different languages represent content from different countries.</p>
        <p>Release year. Considered somewhat for diversification, as content from different
periods of time can offer different perspectives.</p>
        <p>Besides these five types of metadata, four more types of available metadata were discussed:
country, duration, title, and credit. Country was considered similar to language and
therefore offering less additional value. Duration was considered unimportant for
recommendation. Title and credit (makers) of content were considered important for
matching users’ interests, but too specific to be of practical use for automatic
recommendation.</p>
      </sec>
      <sec id="sec-2-3">
        <title>2.3. Designing prototypes</title>
        <p>Combining the conceptual recommendation models (2.1) with the metadata from the PSM
organization (2.2), the authors of this paper created four distinct prototypes of
recommenders. Each recommender prototype personalizes recommendations on certain
metadata, i.e., offer content that matched the user’s interests and needs, and offers diversity
in recommendations on other metadata, i.e. offer a variety of content. Table 1 offers an
overview of the different combinations of personalization and diversification for the
different prototypes.
These prototypes should not be considered as ‘the way’ to operationalize the different
conceptual models, but as ‘best guesses’ by the authors. We believe that this is not a problem
as the aim of presenting the prototypes to the stakeholders is to foster discussion and
decision making about combining personalization and diversification in recommendation
systems.</p>
      </sec>
      <sec id="sec-2-4">
        <title>2.4. Sharing prototypes with stakeholders</title>
        <p>In the final step, the prototypes were shared with a group of six stakeholders, consisting of
developers, content curators, and employees from the innovation department. The
prototypes from Table 1 were presented as visualizations showing the diverse content
outputs that could potentially result from the different recommenders. The stakeholder's
repository of television programs, TV series, documentaries, and related content was
utilized to showcase this potential output.</p>
        <p>The aim of this step was to facilitate an open discussion about different (conceptual)
choices to make by enabling the stakeholder to gain a clear understanding of the impact of
different conceptual and metadata choices on the possible recommendations. In the
discussion, the stakeholders acknowledged the value of the different conceptual models of
recommendation, appreciated the effort to translate them into concrete prototypes, and
stated that these prototypes gave them new insights in the challenge at hand. A variety of
topics was discussed, including what they thought about the different prototypes, the lack
of the decision power of the stakeholders at the session, the bureaucracy of the organization
hindering the decision-making process, the limited availability of metadata, the lack of time
and resources in the project, the importance of UX design, and users’ perception of the
organization.</p>
      </sec>
    </sec>
    <sec id="sec-3">
      <title>3. Discussion and conclusion</title>
      <p>Though the stakeholders acknowledged the value of the four prototypes, the discussion in
the session did not center around the different options and choices to make in the
development process of the recommendation system. Thus, our intervention helped less in
moving the development process forward than we intended. Yet, we believe that our
observations from the session may reveal patterns of responsible AI in practice that are not
unique to this specific case study and are therefore worthwhile reflecting upon.</p>
      <p>
        Responsible AI involves making ethical and sometimes political choices, which is difficult
and requires taking responsibility and being brave [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. The stakeholders present in the
session seemed reluctant to take this responsibility. Analyzing our observations from the
session, we identify three different strategies the stakeholders used to steer the
conversation away from making actual choices. The first strategy is to talk about resources
that responsible AI require and the lack thereof, such as money, time and data. The second
strategy is to discuss aspects in the organizational governance that hinder developing and
implementing responsible AI, such as unclear responsibilities, procedures and guidelines.
The third strategy for avoiding difficult topics and choices is by making use of complexity of
the challenge at hand, by continually introducing new aspects that relate to the challenge in
such a way that the conversation keeps going without moving forward.
      </p>
      <p>This paper described a case study in which we supported a PSM organization in
developing a recommendation system. The study shows the value of prototypes in a design
process but also the complexity of responsible AI in practice. In future work, we intend to
experiment more with facilitating responsible AI processes in practice, and study whether
the strategies for avoiding making complex decisions can be observed in other contexts and
organizations as well. If so, a next step would be to develop and evaluate interventions for
overcoming these avoidance strategies.</p>
