Abstract: To build domain ontology is an important part of ontology research and application areas. hhis paper proposed the process and algorithm of automatic construction of ontologies with data mining and machine learning technologies for web information resources. During the procedure of ontology construction, this paper firstly presented the process and algorithm of concepts classification with muti classifiers based on Bayes classification principle, then discussed the algorithms of concepts-associated analysis and concept self-learning to build the ontology prototype, whereafter presented ontology transforming mechanism from ontology prototype to OWL ontology. This paper also proposed a whole system solution from mining web pages, building domain ontology to the end of ontology application.
