An Automatic Ontology Learning Approach Based on Web Information Items for Web Information Extraction
摘要
Abstract
According to the weakness of building ontology needs manually designated concepts and instances from the basic information of web, an automatic ontology learning approach based on web information items is designed. Utilizing preresearch that an arithmetic of an inductive learning based on DOM for the similar path of information items and an approach for identifying automatic keyword based on PAT-tree, the learning for the concepts and the relation between concepts is implemented by using an approved TFIDF statistic method and an algorithm of composite event association rule, the information item ontology is built, the manual workload for building ontology is reduce关键词
