摘要
[目的/意义]随着科技文献资源的急剧增长,用户淹没在科技文献的海洋中,为用户提供快速、精准的细粒度知识元服务将成为未来文献知识检索的发展趋势。[方法/过程]在分析科技文献文本结构的基础上,逐步深入到科技文献的内容中,以期通过构建一种面向科技文献知识表示的知识元本体模型,将科技文献内容中句义完整的细粒度知识点表示成具有统一结构的知识元。[结果/结论]以一篇科技文献为实例,展示笔者提出的基于知识元本体模型的科技文献知识表示方法,但该示例仅呈现了科技文献中引言部分的相关知识点,需进一步验证该知识元本体模型的有效性。
[ Purpose/significance ] the ocean of scientific literature, and the accurate fine-grained knowledge element With the rapid growth of scientific literature resources, users are surrounded by future trend of the document knowledge retrieval is to provide users with fast and services. [ Method/process] Based on the analysis of the content structure of scientific literature, this paper went gradually and deeply into the scientific literature contents, a view of constructing a knowledge element ontology model of scientific literature for the knowledge representation, to express fine-grained knowl- edge points owning holonomic sentence meanings in the content of scientific literature as knowledge elements with a unified structure. [ Result/conclusion ] The paper illustrates the rationality of the model of scientific literature by the means of displaying the content of a scientific literature, but this example only shows knowledge points in the introduction of scien- tific literature and the knowledge element ontology model needs to be further verified.
