• Title: SocialVec: Social Entity Embeddings
• Authors: Nir Lotan, Einat Minkov
• Abstract summary: This paper introduces SocialVec, a framework for eliciting social world knowledge from social networks. We learn social embeddings for roughly 200,000 popular accounts from a sample of the Twitter network. We exploit SocialVec embeddings for gauging the political bias of news sources in Twitter.

• Abstract: This paper introduces SocialVec, a general framework for eliciting social world knowledge from social networks, and applies this framework to Twitter. SocialVec learns low-dimensional embeddings of popular accounts, which represent entities of general interest, based on their co-occurrences patterns within the accounts followed by individual users, thus modeling entity similarity in socio-demographic terms. Similar to word embeddings, which facilitate tasks that involve text processing, we expect social entity embeddings to benefit tasks of social flavor. We have learned social embeddings for roughly 200,000 popular accounts from a sample of the Twitter network that includes more than 1.3 million users and the accounts that they follow, and evaluate the resulting embeddings on two different tasks. The first task involves the automatic inference of personal traits of users from their social media profiles. In another study, we exploit SocialVec embeddings for gauging the political bias of news sources in Twitter. In both cases, we prove SocialVec embeddings to be advantageous compared with existing entity embedding schemes. We will make the SocialVec entity embeddings publicly available to support further exploration of social world knowledge as reflected in Twitter.

  We propose a novel approach that recognizes textbfContextual textbfSocial textbfRelationships (textbfConSoR) from a social cognitive perspective. We construct social-aware descriptive language prompts with social relationships for each image. Impressively, ConSoR outperforms previous methods with a 12.2% gain on the People-in-Social-Context (PISC) dataset and a 9.8% increase on the People-in-Photo-Album (PIPA) benchmark.

  Social recommendation models weave social interactions into their design to provide uniquely personalized recommendation results for users. Existing social recommendation models fail to address the issues of popularity bias and the redundancy of social information. We propose a Condition-Guided Social Recommendation Model (named CGSoRec) to mitigate the model's popularity bias.

  Social world knowledge is a key ingredient in effective communication and information processing by humans and machines alike. We introduce SocialVec, a framework for eliciting low-dimensional entity embeddings from the social contexts in which they occur in social networks. Similar to word embeddings which facilitate tasks that involve text semantics, we expect the learned social entity embeddings to benefit multiple tasks of social flavor.

  Fake news on social media is a major problem with far-reaching negative repercussions on both individuals and society. In this work, we create a model through which we hope to offer a solution that will instill trust in social network communities. Our model analyses the behaviour of 50,000 politicians on Twitter and assigns an influence score for each evaluated user.

  We propose an end-to-end ensemble-based architecture to automatically identify and classify aggressive tweets. Tweets are classified into three categories - Covertly Aggressive, Overtly Aggressive, and Non-Aggressive. Our best model is an ensemble of Capsule Networks and results in a 65.2% F1 score on the Facebook test set, which results in a performance gain of 0.95% over the TRAC-2018 winners.
