The Design And Implementation Of Content Filtration Model Based On Domain Ontology

Nowadays, the information technology grows rapidly, wireless message service is full of useless information along with the service becoming large. How to filter these messages is the hot problem in the field of information technology. In this article, the information content becomes the focus of the Chinese filtering technology study.This article mainly describes the domain ontology based content filtering prototype system that has the instance of the short message filtering system with domain ontology and reasoning theory. The Main jobs are:Collecting a large number of knowledge information in the advertisement domain, summarizing the whole ad and commodity classification. Using the official commodity classification standard and the extensive ad types. For the dimness of the natural language description, we must neaten and analyze the knowledge, come to a clear and broad ad domain knowledge base.Completing the building of the ad domain ontology. From the collection of domain knowledge, we abstract and build the ad domain ontology. It supports the system with the important information base and relation base. Meanwhile, through consummation using the module into the short message filtering system.Using the concepts of the knowledge ontology base, we match the object content from the word segment dictionary. Here setting up a word segment dictionary query mechanism, we match the words in the two different word dictionaries, specially do it in the basic word dictionary, and come to the collection of terms for reasoning.Bringing forward the knowledge based querying and reasoning mode, coming to the exact ad concepts classification through the logic operation, we can make sure of the content property with the classification. Finally, we get the system results.Building the content filtering system module, and bringing forward the knowledge feedback mode. In filtering system, we classify the messages basically, and store it in the feedback knowledge database, offer the data to domain experts. The article shows some study of other applications about domain ontology.Integrating the knowledge base with information filtering system, building the ad...
