Despite the prevalence of Graph Autoencoders, there has been limited\u0000focus on developing and evaluating explainable neural-based graph generative\u0000models specifically designed for signed networks. To address this gap, we\u0000propose the Signed Graph Archetypal Autoencoder (SGAAE) framework. SGAAE\u0000extracts node-level representations that express node memberships over distinct\u0000extreme profiles, referred to as archetypes, within the network. This is\u0000achieved by projecting the graph onto a learned polytope, which governs its\u0000polarization. The framework employs a recently proposed likelihood for\u0000analyzing signed networks based on the Skellam distribution, combined with\u0000relational archetypal analysis and GNNs. Our experimental evaluation\u0000demonstrates the SGAAEs' capability to successfully infer node memberships over\u0000the different underlying latent structures while extracting competing\u0000communities formed through the participation of the opposing views in the\u0000network. Additionally, we introduce the 2-level network polarization problem\u0000and show how SGAAE is able to characterize such a setting. The proposed model\u0000achieves high performance in different tasks of signed link prediction across\u0000four real-world datasets, outperforming several baseline models.","PeriodicalId":501032,"journal":{"name":"arXiv - CS - Social and Information Networks","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing emoji recommendation methods\u0000are primarily evaluated based on their ability to match the exact emoji a user\u0000chooses in the original text. However, they ignore the essence of users'\u0000behavior on social media in that each text can correspond to multiple\u0000reasonable emojis. To better assess a model's ability to align with such\u0000real-world emoji usage, we propose a new semantics preserving evaluation\u0000framework for emoji recommendation, which measures a model's ability to\u0000recommend emojis that maintain the semantic consistency with the user's text.\u0000To evaluate how well a model preserves semantics, we assess whether the\u0000predicted affective state, demographic profile, and attitudinal stance of the\u0000user remain unchanged. If these attributes are preserved, we consider the\u0000recommended emojis to have maintained the original semantics. The advanced\u0000abilities of Large Language Models (LLMs) in understanding and generating\u0000nuanced, contextually relevant output make them well-suited for handling the\u0000complexities of semantics preserving emoji recommendation. To this end, we\u0000construct a comprehensive benchmark to systematically assess the performance of\u0000six proprietary and open-source LLMs using different prompting techniques on\u0000our task. Our experiments demonstrate that GPT-4o outperforms other LLMs,\u0000achieving a semantics preservation score of 79.23%. Additionally, we conduct\u0000case studies to analyze model biases in downstream classification tasks and\u0000evaluate the diversity of the recommended emojis.","PeriodicalId":501032,"journal":{"name":"arXiv - CS - Social and Information Networks","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142263435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this limitation, we propose a new class of\u0000parameterized Laplacian matrices, which provably offers more flexibility in\u0000controlling the diffusion distance between nodes than the conventional graph\u0000Laplacian, allowing long-range information to be adaptively captured through\u0000diffusion on graph. Specifically, we first prove that the diffusion distance\u0000and spectral distance on graph have an order-preserving relationship. With this\u0000result, we demonstrate that the parameterized Laplacian can accelerate the\u0000diffusion of long-range information, and the parameters in the Laplacian enable\u0000flexibility of the diffusion scopes. Based on the theoretical results, we\u0000propose topology-guided rewiring mechanism to capture helpful long-range\u0000neighborhood information for heterophilic graphs. With this mechanism and the\u0000new Laplacian, we propose two GNNs with flexible diffusion scopes: namely the\u0000Parameterized Diffusion based Graph Convolutional Networks (PD-GCN) and Graph\u0000Attention Networks (PD-GAT). Synthetic experiments reveal the high correlations\u0000between the parameters of the new Laplacian and the performance of\u0000parameterized GNNs under various graph homophily levels, which verifies that\u0000our new proposed GNNs indeed have the ability to adjust the parameters to\u0000adaptively capture the global information for different levels of heterophilic\u0000graphs.

Such behavior not only disrupts the order of the financial\u0000market but also harms economic and social development and breeds other illegal\u0000and criminal activities. With the popularization of the internet and online\u0000payment methods, many fraudulent activities and money laundering behaviors in\u0000life have shifted from offline to online, posing a great challenge to\u0000regulatory authorities. How to efficiently detect these financial fraud\u0000activities has become an urgent issue that needs to be resolved. Graph neural\u0000networks are a type of deep learning model that can utilize the interactive\u0000relationships within graph structures, and they have been widely applied in the\u0000field of fraud detection. However, there are still some issues. First,\u0000fraudulent activities only account for a very small part of transaction\u0000transfers, leading to an inevitable problem of label imbalance in fraud\u0000detection. At the same time, fraudsters often disguise their behavior, which\u0000can have a negative impact on the final prediction results. In addition,\u0000existing research has overlooked the importance of balancing neighbor\u0000information and central node information. For example, when the central node\u0000has too many neighbors, the features of the central node itself are often\u0000neglected.

Linking users\u0000across social networks can have multiple implications in several contexts both\u0000at the individual level and at the group level. At the individual level, the\u0000main interest in linking the same identity across social networks is to enable\u0000a better knowledge of each user. At the group level, linking user identities\u0000through different OSNs helps in predicting user behaviors, network dynamics,\u0000information diffusion, and migration phenomena across social media. The process\u0000of tying together user accounts on different OSNs is challenging and has\u0000attracted more and more research attention in the last fifteen years.
