内容記述 |
This paper presents our work in the Lifelog Semantic Access Task (LSAT) at NTCIR-18, focusing on automatic searching methods for finding distinct life moments. Our experiments explore and compare different retrieval strategies, including keyword matching-based search combined with embedding extraction, vector embedding-based semantic search using a multimodal model, and hybrid methods that take advantage of both approaches. Our proposed method improved retrieval accuracy by directing the model's attention to key query terms while prioritizing semantic relevance and the presence of requested entities in the retrieved moments. Experimental results demonstrated that the best-performing method relies on embeddings incorporating extended descriptions and highlighted keywords. Conversely, the hybrid methods in our experiments have less effective results, likely due to limitations in the keyword-matching search algorithm. This work's findings underscore the richer descriptive entities within queries to enhance the retrieval of life moments, ensuring a focus on core semantic and visual elements. |
