数字图书馆数值知识元检索系统设计
Research on Retrieval of Numerical Knowledge Element in Digital Library
摘要
[目的/意义]为满足数字图书馆用户对数值知识的个性化检索需求，向其提供细粒度的知识服务。[方法/过程]基于对数值知识元的深入分析，提出数字图书馆数值知识元识别、抽取、索引与检索方法，并构建一个面向数值知识元的检索系统。[结果/结论]通过实例分析验证基于数值知识元的细粒度知识服务能够在一定程度上提高检索和利用数值知识的效率和用户满意度。
Abstract
[Purpose/significance] This paper aims to meet personalized retrieval needs of digital library users for numerical knowledge, and realize the fine-grained knowledge service.[Method/process] Based on the analysis of numerical knowledge element, it proposes a method of identifying, extracting, indexing and retrieving numerical knowledge elements, and constructs a retrieval system for numerical knowledge elements. [Result/conclusion] In addition, the case study shows that the meta-knowledge service based on numerical knowledge can improve the efficiency and user satisfaction of retrieving and using numerical knowledge.关键词
