| 摘 要： | 科技文献资源是一种多模态数据,除文本信息外,还包含丰富的图像、表格、公式、音频、视频等多种模态的信息,有利于用户充分理解科技文献资源中的知识。该文把多模态思想引入科技文献的语义表示方面,对科技文献中的图像、表格和公式信息进行语义分析,与文本信息共同表示文献语义内容,通过科技文献中多种模态信息的语义表示及相互关系完善科技文献内容的语义化表示,发展刻画科技文献对象多态性的表达体系。

| Abstract: | Scientific and technical literature contains images,tables,formulas,audio and video files besides the common text format,which will help the users to fully understand the knowledge presented in the literature.So the resource of scientific and technical literature can be taken as a kind of multi-modal information.This paper adopts the multi-modal approach to make the semantic presentation of the scientific and technical literature.To be specific,it analyzes the texts,images,tables and formulas in the literature on the semantic level,builds a system to present the semantic multi-modal features in the literature,and optimizes the semantic presentation of the literature with the semantic features and the relations between them. |
