abstract = {Web-based technologies are widely used as production tools for time-driven media and as interfaces for live reporting of time-sensitive developments. Time-driven media face growing demands for interactivity, adaptation, and personalization, suggesting a more web-like model where layer orchestration and time-sensitive rendering increasingly occur on the client side, within data-driven consumer interfaces. Yet realizing this shift is challenging. Time-driven media production relies on precise control over layering—when layers are activated, deactivated, and how they are combined and displayed. In data-driven platforms, however, support for external, time-sensitive control is weak, and layer orchestration and playback are handled by distinct media frameworks—each constrained to a particular application context and technology stack. Our approach is to shift the problem from media frameworks to the data model. By supporting production-controlled layering and playback within application state, time-driven media experiences can be realized as native expressions of data-driven platforms, fully exploiting available rendering technologies and backend services. The main contribution is State-based Layering (SbL), a conceptual framework for developing controllable, time-dependent application state. SbL generalizes concepts defined within existing media frameworks, promoting them as generic programming constructs—independent of data formats and user interfaces, and applicable across diverse application contexts. StateLayers, a reference implementation of SbL, shows that timing, control, and layering can be fully encapsulated within application state and remain compatible with modern development workflows. SbL marks an important step toward scalable personalization, enabling production systems to directly shape unique time-driven narratives for individual users through real-time control over consumer interfaces.},

abstract = {Misinformation and disinformation threaten global public trust in news media. Generative AI exacerbates mistrust by making it difficult to distinguish authentic images from AI-generated ones. This study examines whether accompanying images with C2PA (Coalition for Content Provenance and Authenticity) provenance labels can restore trust. C2PA is an open standard that cryptographically secures and describes a media file’s origin and editing history. We conducted an online experiment with $N=6,114$ participants, reflecting audiences of six major news sources in the US, UK, and Norway. Each participant evaluated six news article previews with images, either accompanied by a provenance label (three levels of detail) or not. Presenting provenance metadata to participants significantly improved their perceptions of an image’s transparency and credibility, and also increased feelings of trust in a presented news source. These results show that verifiable provenance makes visual content more inspectable and strengthens brand trust. By adopting C2PA or similar frameworks, news organizations can counter AI-generated disinformation and improve audience trust.},

Large Language Models (LLMs) offer strong language understanding capabilities but suffer from opacity and brittleness, particularly in reasoning over numerical claims. This work explores how Explainable Artificial Intelligence (XAI)-through the lens of counterfactual explanations and adversarial training-can be used to systematically evaluate and improve the robustness of LLMs against perturbed numerical inputs. We propose a framework that employs counterfactual generation to both probe LLM reliability and generate user-appropriate explanations. Through empirical evaluations using a large-scale numerical fact-checking dataset (QuanTemp), we show that even state-of-the-art LLMs are susceptible to subtle numerical perturbations, impacting verdict accuracy. Our methodology contributes a dual-purpose diagnostic and training strategy that not only bolsters robustness but also enables both global and local interpretability-thereby improving explainability in automated fact-checking systems.},

Amid concerns about filter bubbles and preference volatility, we propose an empirical evaluation of both short-term and longer-term effects of a news recommender system with two phases of data collection: Initial preference elicitation and evaluation (Phase 1), a 48-hour interval, and a personalized follow-up (Phase 2). We compared two recommendation strategies in a preliminary longitudinal experiment (? = 166): An ‘Aligned’ feed that included articles that met a ≥ 70% cosine‐similarity threshold, and a ‘Disaligned’ feed with only a 30% similarity threshold. We collected behavioral metrics (article clicks, time on feed) and evaluative metrics (self-reported familiarity, perceived recommendation quality, choice satisfaction, topic preferences) in both phases. The Aligned feed was perceived to have more familiar content, while perceived diversity did not differ between recommendation strategies. Users clicked on significantly fewer articles in Phase 2, particularly in the Disaligned condition. We also explored the volatility of topic preferences, but did not observe significant differences across phases. These findings suggest that short-term increases in feed–profile similarity can enhance familiarity and maintain behavioral engagement (i.e., clicks). In contrast, they do not lead to higher levels of perceived quality and choice satisfaction, which raises doubts about the relationship between the similarity of preference-based articles and user satisfaction.},

abstract = {Rising user concerns about online misinformation and the spread of AI-generated visual content underscore the need for better ways to verify image authenticity. Image provenance labels are a proposed solution, aiming to help users assess the veracity of digital images. The Coalition for Content Provenance and Authenticity (C2PA), for instance, can disclose image provenance (i.e., origin or source details) to users in the form of labels that describe the image's metadata. However, little is known about whether users engage with or understand such labels, especially in news recommender contexts. In this paper, we introduce an alternative `Image Trust Score' label, inspired by the front-of-package Nutri-Score label, and experimentally evaluate its effectiveness in a personalized news setting. We present the results of a four-condition (no-label baseline, C2PA label, black-and-white and colored Image Trust Score) between-subjects study (N=202) in which participants selected news articles (with or without labels), reporting on label comprehension and trust. While image trust and article selection were not significantly affected, all labels increased article trust. The Image Trust Score was perceived as more understandable and appealing than the C2PA label, though many participants misinterpreted the labels' meaning. Our findings highlight the need for clearer and more intuitive provenance label design.},

abstract = {News recommender systems (NRSs) increasingly leverage artificial intelligence to automate journalistic processes and tailor content to individual users. These systems are shaping patterns of news consumption. The emotional reframing of the content of the news article, applied through large language models (LLM), has the potential to influence the selection of the articles of users and guide them towards specific content. This paper explores how emotional reframing of news articles can influence user engagement, interaction, and openness to non-preferred content. We present the results of a user study (N = 150) on a news platform. How news articles were presented was subject to a 3x2-mixed research design. News articles were rewritten using a large language model (LLM) in one of three emotional tones: fearful, angry, or hopeful. Moreover, articles either aligned with the user's emotional state and topical preferences or not. These emotionally reframed articles were then either aligned or misaligned with users' self-reported emotional state to examine the effect of emotional alignment. The results show that emotional alignment significantly increased the likelihood that users selected an article as their favorite, even when it belonged to their least preferred topic category. This finding suggests that emotional alignment can guide users toward content they might otherwise avoid, offering a potential means to reduce selective exposure. In terms of behavioral engagement, articles reframed with an angry tone significantly led to longer reading times, while fearfully framed articles were more likely to be clicked. In contrast, hopeful framing resulted in reduced interaction, which suggests that negative rather than positive emotions increase user engagement.},

While they address the challenge of choice overload, their direct influence on promoting healthier food choices remains limited. Digital nudges could further assist in guiding users toward healthier decisions, enhancing the accessibility and visibility of healthy options when integrated into a recommender system. This review examines to what extent food recommender systems have so far successfully incorporated digital nudges for healthy food promotion and which challenges still remain. We present a classification and analysis of various digital nudging strategies employed for this purpose, as well as opportunities for future research. We emphasize that various nudging techniques have the potential to support users in making healthier food choices within food recommender systems.

Our methodology involves using a set of templates constructed around stimuli and attributes relevant to these categories. We use statistical and predictive evaluation methods, including Kendall’s Tau correlation and dependent variable prediction rates, to assess model behaviour and output bias. Our findings indicate that models frequently associate older individuals, people with disabilities, and poorer countries with negative attributes, potentially reinforcing harmful stereotypes. However, most tested models appear to handle gender-related biases more effectively. Our findings indicate a correlation between the sentiment of the input and that of the output.},

To date, LLM use in a journalism context has been understudied, but can potentially address challenges of selective exposure and polarization by adapting content to end users. This study used a one-shot recommender platform to test whether LLM-generated news summaries were evaluated more positively than `standard' 50-word news article previews. Moreover, using climate change news from the Washington Post, we also compared the influence of different `emotional reframing' strategies to rewrite texts and their impact on the environmental behavioral intentions of end users. We used a 2 (between: Summary vs. 50-word previews) x 3 (within: fear, fear-hope or neutral reframing) research design. Participants (N = 300) were first asked to read news articles in our interface and to choose a preferred news article, while later performing an in-depth evaluation task on the usability (e.g., clarity) and trustworthiness of different framing strategies. Results showed that evaluations of summaries, while being positive, were not significantly better than those of previews. We did, however, observe that a fear-hope reframing strategy of a news article, when paired with a GPT-generated summary, led to higher pro-environmental intentions compared to neutral framing. We discuss the potential benefits of this technology.},

abstract = {This paper integrates a top-down analysis of the existing literature on academia-industry collaboration (AIC) with a bottom-up qualitative study consisting of 16 anonymised interviews. From a variety of academic and industry sources we identified three dominant discourses that are frequently drawn upon. These often-repeated statements, while partially true, act to obscure considerably complexity and nuance. In an effort to expand existing AIC discourse, we introduce two key concepts: grounding and anchoring. These can take place in an organisational or a personal context. An AIC project is personally grounded, when individuals involved in the project feel that the work is meaningful to them, that it is aligned with their wider values and is making a difference to the world. Analogously, organisational grounding indicates that a project is consistent with the culture and values of the organisation. An AIC project is personally anchored when the people responsible for it feel a strong sense of ownership and agency towards the project. Organisational anchoring indicates that a project is fully supported within the organisation, in particular by the relevant managers and executives. When a project is sufficiently grounded and anchored, success and the personal satisfaction of the people involved in the activity are more likely to follow.

abstract = {Political debates are essential in political discourse for democratic societies. Advancements in technology have significantly transformed the structure of political debates, the ways in which politicians communicate, and the platforms through which audiences engage with them. Originally a forum for improving understanding, political debates have increasingly favored theatrics over substance, risking young adult disengagement. To bring substance back to this medium we developed AiModerator, a political debate co-pilot acting as a Multimodal Conversational Agent (MCA). AiModerator aims to promote engagement while improving understanding by analyzing video content to provide contextually relevant information. This consolidated information facilitates understanding while keeping users synchronized with the debate viewing experience. Our system builds upon multimodal techniques, integrating computer vision and large language models to demonstrate ways of improving content delivery and engagement. AiModerator's backend system extracts events from identified speech data, allowing the user to interact with these events through a touch interface on an iPad application. We address three key topics: evaluating young adults' engagement, satisfaction, and preference compared to traditional second screening, and determining whether AiModerator can improve subjective understanding. To evaluate these measures we conducted a mixed-method evaluation (n=20) within-group design A-B study. Our analysis found AiModerator excelled in promoting engagement and satisfaction while delivering clear, contextually relevant information to the user which improved their understanding of debate topics more than the second screening mode. Our qualitative analysis offers broader insights, particularly in terms of a trade-off between automation and information consolidation versus autonomy and control.},

This unique capability allows users to listen to the podcast and annotate key elements, such as check-worthy claims, claim spans, and contextual errors, simultaneously. By integrating advanced transcription models like OpenAI's Whisper and leveraging crowdsourced annotations, we create high-quality datasets to fine-tune multilingual transformer models such as XLM-RoBERTa for tasks like claim detection and stance classification. Furthermore, we release the annotated podcast transcripts and sample annotations with preliminary experiments.},

In this paper, we report on the outcomes of an A/B test on a video and movie streaming platform, where we benchmarked a sequential model against a non-sequential, personalized recommendation model, as well as a popularity-based baseline. Contrary to what we had expected from a preceding offline experiment, we observed that the popularity-based and the non-sequential models led to the highest click-through rates. However, in terms of the adoption of the recommendations, the sequential model was the most successful one in terms of viewing times. While our work points out the effectiveness of sequential models in practice, it also reminds us about important open challenges regarding (a) the sometimes limited predictive power of classic offline evaluations and (b) the dangers of optimizing recommendation models for click-through-rates.},

This study aims to see these dimensions as connected, emphasizing the significance of understanding how news content, practices, and people’s situatedness resonate in the context of everyday life and how this resonance reflects personal identity. Conceptually, the paper employs the concept of news experience as an analytical lens to understand the multilayered nature of how people relate to news. Empirically, six distinct forms of news experience are identified, all in which content, practices, and situatedness resonate differently: Reassurance, control, connection, relaxation, diversion, and stress. Drawing on a Norwegian three-step data collection, including recurring interviews, news diaries, data donations, and video-ethnography from the same informants, the article methodologically contributes to a more profound understanding of the dynamics involved in various forms of news experience.},

While there is extensive literature work in this area, developing an evaluation method that is both objective and quantitative is still challenging task requiring more effort. In this study, we proposed a new Clustering Stability Assessment Index (CSAI) that can provide a unified and quantitative approach to measure the quality and consistency of clustering solutions.

In particular, a healthy democracy requires a balanced and diverse media landscape, able to provide an arena in which the various topics and viewpoints relevant to the political discourse of the day are presented and discussed. To address this issue, we have developed a hybrid human-machine approach, which uses a Large Language Model first to help analysts identify the range of viewpoints relevant to the debate around a given topic and then to classify the claims expressed in the news corpus of interest with respect to the identified viewpoints. We tested a variety of LLMs on a benchmark corpus of news items drawn from British media sources. Our results indicate that GPT4o outperforms the other alternatives and can already provide effective support for this classification task, even when run in a zero-shot learning modality.},

abstract = {Recent developments in artificial intelligence allow newsrooms to automate journalistic choices and processes. In doing so, news framing can impact people's engagement with news media, as well as their willingness to pay for news articles. Large Language Models (LLMs) can be used as a framing tool, aligning headlines with a news website user's preferences or state. It is, however, unknown how users perceive and experience the use of a platform with such LLM-reframed news headlines. We present the results of a user study (N = 300) with a news recommender system (NRS). Users had to read three news articles from The Washington Post from a preferred category (abortion, economics, gun control). Headlines were rewritten by an LLM (ChatGPT-4) and images were replaced in specific affective styles, across 2 (positive or negative headlines) x 3 (positive or negative image, or no image) between-subject framing conditions. We found that negatively framed images and text elicited negative emotions, while positive framing had little effect. Users were also more willing to pay for a news service when facing negatively framed headlines and images. Surprisingly, the congruency between text and image (i.e., both being framed negatively or positively) did not significantly impact engagement. We discuss how this study can shape further research on affective framing in news recommender systems and how such applications could impact journalism practices.},

Among these are selective exposures that may contribute to polarization, potentially reinforcing existing attitudes through belief perseverance—discounting contrary evidence due to their opposing attitudinal strength. This can be unsafe for people, making it difficult to accept information objectively. A crucial issue in news recommender system research is how to mitigate these undesired effects by designing recommender interfaces and machine learning models that enable people to consider to be more open to different perspectives. Alongside accurate models, the user experience is an equally important measure. Indeed, the core statistics are based on users’ behaviors and experiences in this research project. Therefore, this research agenda aims to steer the choices of readers' based on altering their attitudes. The core methods plan to concentrate on the interface design and ML model building involving manipulations of cues, users’ behaviors prediction, NRSs algorithm and changing the nudges. In sum, the project aims to provide insight in the extent to which news recommender systems can be effective in mitigating polarized opinions.},

An investigation of the interaction log data from an online newspaper revealed that while the editorial staff is focusing on content that is generally popular across large parts of the audience, the algorithmic curation can, in addition, provide small yet noteworthy personalization touches for individual readers. The results of the analysis demonstrate an example of a successful coexistence of editorial and algorithmic news curation.},

By employing comparative analysis, key variables influencing armed conflicts are identified and analyzed. The framework includes a meta-model representing domain concepts such as the goals and strategies of conflicting parties, escalating stages, and impacts of conflicts. Conflict escalation is a complex process characterized by interactions between opposing parties. This paper presents a structured model that outlines how conflicts evolve and intensify over time. We adapt a meta-modeling framework called the Diagram Predicate Framework (DPF) to represent conflict-related concepts and extend it to support abstract view generation. This framework facilitates the analysis of conflict trends and the study of dynamics across various levels of abstraction. A computational model based on category theory is proposed for trend analysis, enabling the extraction of patterns of conflict evolution and the comparison of strategies and goals at different escalation stages. Categorical operations such as pullback and limit construction are employed to compute conflict evolution and identify common structures among conflict instances, providing insights into conflict dynamics across diverse zones.},

abstract = {Online news article recommendations are typically of the ‘more like this’ type, generated by similarity functions. Across three studies, we examined the representativeness of different similarity functions for news item retrieval, by comparing them to human judgments of similarity. In Study 1 (N = 401), participants assessed the overall similarity of ten randomly paired news articles on politics, and compared their judgments to different feature-specific similarity functions (e.g., based on body text or images). In Study 2, we checked for domain differences in a mixed-methods survey (N = 45), surfacing evidence that the effectiveness of similarity functions differs across different news categories (‘Recent Events’, ‘Sport’). In Study 3 (N = 173), we improved the design of Study 1, by controlling for how news articles were matched, differentiating between dissimilar news articles and articles that were matched on a shared topic, named entities, and/or date of publication, across ‘Recent Events’ and ‘Sport’ categories.
Across all studies, we found that users mostly used text-based features (e.g., body text, title) for their similarity judgments, while BodyText:TF-IDF was found to be the most representative for their judgments. Moreover, the strength of similarity judgments by humans and similarity scores by feature-specific functions was strongly affected
by how news article pairs were matched. We show that humans and similarity functions are better aligned when two news articles are more alike, such as in a news recommendation scenario.},

abstract = {Research in the recommender systems field typically applies a rather traditional evaluation methodology when assessing the quality of recommendations. This methodology heavily relies on incorporating different forms of user feedback (e.g., clicks) representing the specific needs and interests of the users. While this methodology may offer various benefits, it may fail to comprehensively project the complexities of certain application domains, such as the news domain. This domain is distinct from other domains primarily due to the strong influence of editorial control in the news delivery process. Incorporation of this role can profoundly impact how the relevance of news articles is measured when recommended to the users. Despite its critical importance, there appears to be a research gap in investigating the dynamics between the roles of editorial control and personalization in the community of recommender systems. In this paper, we address this gap by conducting experiments where the relevance of recommendations is assessed from an editorial perspective. We received a real-world dataset from TV 2, one of the largest editor-managed commercial media houses in Norway, which includes editors’ feedback on how news articles are being related. In our experiment, we considered a scenario where algorithm-generated recommendations, using the K-Nearest Neighbor (KNN) model, employing various text embedding models to encode different sections of the news articles (e.g., title, lead title, body text, and full text), are compared against the editorial feedback. The results are promising, demonstrating the effectiveness of the recommendation in fulfilling the editorial prospects.},

abstract = {News Recommender Systems (NRSs) have become increasingly pivotal in shaping the news landscape, particularly in how news is disseminated. This has also led to concerns about information diversity, especially regarding selective exposure in the realm of political news. Users may not recognize that news content presented to them is subject to selective exposure, through users that incorporate political beliefs. Within the U.S. two-party system, our research explores the interactions between NRSs and users’ ability to discern news articles that align with their political biases. We performed an online experiment (N = 160) to address the issue of user awareness and self-recognition of selective exposure within NRSs. Users were asked to select any number of news articles that matched their political orientation (i.e., Democrat or Republican) from a list of 50 news articles (5 Democrat, 5 Republican, 40 filler articles), which were either ranked saliently towards their political orientation or randomly. Contrary to expectations, our findings reveal no significant difference in article selection between participants exposed to a baseline random order and those who where presented with the more salient and easy to select version. We did observe that Republicans performed worse than Democrats in identifying aligning articles, based on precision and recall metrics.},
