TSHR-Net: Text Semantic Homogenization Recognition Network for Short Video Title Overlays

Short videos follow the trend of creation, leading to a proliferation of homogenized video content. Textual overlays such as titles in short videos often reflect semantic homogeneity. This phenomenon manifests not only in the syntactic structure and overall thematic expression, but also in local semantic elements such as words and phrases. Based on information retrieval techniques, we propose a text semantic homogenization recognition network (TSHR-Net) for short video title overlays. The framework comprises key components: (1) a dynamic semantic representation that incorporates contextual information of title overlays using RoBERTa pre-trained word embeddings; (2) a dual-path semantic parser that integrates global semantics via BiLSTM-Attention and local semantics via multi-scale TextCNN; (3) a ranking loss optimization is designed to measure cosine similarity between semantic features, thereby improving homogenization recognition accuracy. Experimental results show that our TSHR-Net achieves the competitive performance in Chinese text semantic homogenization recognition, with ρ and ρ X ,Y reaching 80.16% and 78.23% on LCQMC, 81.05% and 80.19% on STS-B(ZH), and 92.47% and 92.19% on our self-built BJUT-HCD. The model also exhibits generalization ability in English, attaining 79.68% and 79.89 on STS-B(EN), and 73.56% and 72.21% on SICK dataset, respectively.
