信息抽取在竞争情报中的应用研究

Research on the Application of Information Extraction in Competitive Intelligence

简要介绍信息抽取的特点和抽取的信息类型,概述信息抽取技术在竞争情报中的应用;在此基础上,提出基于信息抽取技术的竞争情报系统的体系架构,主要包括信息抽取引擎、数据转换与集成、数据清洗、数据装载等,研究信息抽取引擎中封装器的实现方式,并从系统采用的机制和方式、系统功能侧重点、系统的自动化程度等方面分析国外基于信息抽取技术的竞争情报系统的特点。

This paper briefly introduces the characteristics and types of information extraction, and describes the application of information extraction in competitive intelligence. It presents a systematic structure of competitive intelligence based on information extraction in concern with information exaction engines, data conversion and integration, data cleaning, data loading, etc. Furthermore, the paper makes a analysis on the approaches of Wrappers in information exaction engines. Eventually, the paper analyzes the characteristics of Competitive Intelligence Systems abroad from several aspects such as extraction mechanisms, extraction functions, extraction automation degree, etc.
