• Abstract: The last decade has witnessed the proliferation of micro-videos on various user-generated content platforms. According to our statistics, around 85.7\% of micro-videos lack annotation. In this paper, we focus on annotating micro-videos with tags. Existing methods mostly focus on analyzing video content, neglecting users' social influence and tag relation. Meanwhile, existing tag relation construction methods suffer from either deficient performance or low tag coverage. To jointly model social influence and tag relation, we formulate micro-video tagging as a link prediction problem in a constructed heterogeneous network. Specifically, the tag relation (represented by tag ontology) is constructed in a semi-supervised manner. Then, we combine tag relation, video-tag annotation, and user-follow relation to build the network. Afterward, a better video and tag representation are derived through Behavior Spread modeling and visual and linguistic knowledge aggregation. Finally, the semantic similarity between each micro-video and all candidate tags is calculated in this video-tag network. Extensive experiments on industrial datasets of three verticals verify the superiority of our model compared with several state-of-the-art baselines.

  Main obstacle for text-video retrieval is the semantic gap between the textual nature of queries and the visual richness of video content. We propose chunk-level text-video matching, where the query chunks are extracted to describe a specific retrieval unit. We formulate the chunk-level matching as n-ary correlations modeling between words of the query and frames of the video.

  Recognizing the predicate between subject and object pairs is imbalanced and multi-label in nature. Recent state-of-the-art methods predominantly focus on the most frequently occurring predicate classes. We introduce a multi-label meta-learning framework to deal with the biased predicate distribution.

  Existing works on hate speech and offensive language detection produce promising results based on pre-trained transformer models. This paper addresses a multi-task joint learning approach which combines external emotional features extracted from another corpora. Our findings demonstrate that emotional knowledge helps to more reliably identify hate speech and offensive language across datasets.

  We discuss the development of a multilingual dataset annotated with a hierarchical, fine-grained tagset marking different types of aggression and the "context" in which they occur. The initial dataset consists of a total 15,000 annotated comments in four languages. As is usual on social media websites, a large number of these comments are multilingual, mostly code-mixed with English.

  Short-form video social media shifts away from the traditional media paradigm by telling the audience a dynamic story to attract their attention. In particular, different combinations of everyday objects can be employed to represent a unique scene that is both interesting and understandable. Offered by the same company, TikTok and Douyin are popular examples of such new media that has become popular in recent years. The hypothesis that they express cultural differences together with media fashion and social idiosyncrasy is the primary target of our research.

We collect a large-scale dataset accordingly from real-world data in Taobao, a world-leading e-commerce platform.
