基于Web的本体学习模型的设计与实现

对本体(ontology)的研究在计算机科学领域变的越来越广泛,但手工构建本体是一项繁琐而辛苦的任务,还容易导致知识获取瓶颈,无法保持本体的更新。本体学习技术是利用本体工程技术和机器学习技术等众多学科技术来实现本体的自动或半自动构建。该文提出了基于Web的本体学习模型,分析了模型实现中的文档预处理、术语抽取、概念选择、概念分类等关键技术。

Design and Realization for Ontology Learning Model Based on Web

To ontology the research changes in the computer science domain is getting more and more widespread, but constructs the ontology is manually an item tedious and the laborious duty, but also easy to cause the knowledge gain bottleneck, is unable maintains the ontology the renewal.The ontology learning technology is and so on numerous discipline technologies realizes the ontology using the ontology engineering technology and the machine learning technology automatic or the semiautomatic construction.This article proposed based on the Web ontology learning model, analyzed the model to realize the documents pretreatment, the term extraction, the concept choice, the concept classification and so on key technologies.
