Empirical analysis was conducted using 82,539 reviews from nine airlines on TripAdvisor. Initially, the study scrutinizes the combined impact of review sentiment and consumer rating, followed by exploring the influence of review inconsistency on review helpfulness. Our experimental results show that most variables achieved a significance of one thousandth. Additionally, we shed light on the moderating effects of several heuristic clues in the model, including text length, seat class, and region. These findings underscore those heuristic clues that collectively influence the helpfulness of reviews. The outcomes of this research can aid airlines in identifying the most helpful reviews, thereby mitigating consumer search costs and empowering reviewers to contribute more valuable insights.</div></div>","PeriodicalId":50365,"journal":{"name":"Information Processing & Management","volume":"62 4","pages":"Article 104088"},"PeriodicalIF":7.4,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the causal mechanisms driving emotional and behavioral shifts in users posting hateful content remain understudied. This study investigates the causal relationship between engaging in hateful content and changes in linguistic and emotional expression on social media. Using a dataset of 6,002 Twitter/X users, we employ causal inference techniques, including propensity score matching, and advanced topic modeling to compare users posting hateful content with a matched group of non-hateful users. Our main findings can be summarized as follows: (a) Users who post hateful content show significantly higher levels of anger, anxiety, and negative emotions, along with increased third-person pronoun usage. (b) Moral outrage and profanity levels peak during hateful posts but decline over time, while remaining elevated compared to non-hateful posts. (c) Hateful posts are more interconnected, cover more diverse topics, and are more similar to one another, revealing lower cohesion within individual posts but higher cohesion across posts. These findings contribute to understanding the causal effects of online hate speech on user behavior, offering actionable insights for social media platforms to mitigate the spread of hateful content and its broader societal impact.</div></div>","PeriodicalId":50365,"journal":{"name":"Information Processing & Management","volume":"62 3","pages":"Article 104079"},"PeriodicalIF":7.4,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143242449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have developed a novel method to capture real-time emotional responses based on advances in facial emotion classification approaches. We utilize consumer-grade front-facing cameras to collect emotional responses, which synchronize with the user’s interactions with the search interface. In a controlled laboratory study, the relevance of search results was manipulated to validate the approach’s effectiveness and explore how search results’ relevance impacts users’ emotional responses, post-task evaluations of the search interface, and interactions with search interface features. This enabled us to examine whether we could detect emotional responses, whether recency effects were observed in post-task evaluations, and whether feature use correlated with emotional responses. The study was conducted in the context of exploratory search within an academic digital library. The results of this study demonstrate that both positive and negative emotional responses can be reliably detected during the search process. There is evidence of recency effects in post-task measures, and the study identifies specific interactive features used during the experience of positive and negative emotional responses.

Transformer-based SR models have demonstrated promising performance by leveraging self-attention for sequential modeling. Recently, Mamba, a novel sequential model, has shown competitive performance compared to Transformers. In SR tasks, item representation learning involves both global and local context information. While several existing SR models attempt to address this integration, they suffer from inferior performance or computational inefficiency. Moreover, existing Mamba-based SR model appears to capture only the global context information. Given Mamba’s merits in enhancing model performance and efficiency, there is substantial potential to more effectively integrate both global and local context information within a Mamba-based framework.

LC-Mamba captures both global and local context information to improve recommendation performance. Specifically, LC-Mamba leverages a GNN-based sequence encoder to extract information from local neighbors for each item (local context information) in a graph view, while utilizing a Mamba-based sequence encoder to capture dependencies between items in the sequence (global context information) in a sequential view. Furthermore, we introduce consistency training, including model-level and representation-level consistency, to further enhance performance. Specifically, we incorporate R-Drop regularization into the Mamba-based sequence encoder to mitigate the inconsistency between training and inference caused by random dropout (model-level consistency). Additionally, we leverage contrastive learning to enhance consistency between the item representations learned from the sequential and graph views (representation-level consistency). Extensive experiments on three widely used datasets illustrate that LC-Mamba outperforms baseline models in HR and NDCG, achieving up to a 31.03% improvement in NDCG.
