Abstract
En 中文
Efficiently leveraging semantic information is crucial for advancing video captioning in recent years. But, prevailing approaches that involve designing various Part-of-Speech (POS) tags as prior information lack essential linguistic knowledge guidance throughout the training procedure, particularly in the context of POS and initial description generation. Furthermore, the restriction to a single source of semantic information ignores the potential for varied interpretations inherent in each video. To solve these problems, we propose the Exploring Deeper into Semantics (EDS) method for video captioning. EDS comprises three feasible modules that focus on semantic information. Specifically, we propose the Semantic Supervised Generation (SSG) module. It integrates semantic information as a prior, and facilitates enriched interrelations among words for POS supervision. A novel Similarity Semantic Extension (SSE) module is proposed to employ a query-based semantic expansion for collaboratively generating fine-grained content. Additionally, the proposed Input Semantic Enhancement (ISE) module provides a strategy for mitigating the information constraints faced during the initial phase of word generation. The experiments conducted show that, by exploiting semantic information through supervision, extension, and enhancement, EDS not only yields promising results but also underlines the effectiveness. Code will be available at https://github.com/BradenJoson/EDS.
