An Ontology-Supported Website Model for Web Search Agents

Abstract

This paper discusses how an ontology-supported website model helps Web search agents. We advocate the use of ontology-supported website models to provide a semantic level solution for a search engine so that it can provide fast, precise and stable search results. Basically, a website model consists of a website profile for a website and a set of webpage profiles for the webpages contained in the website. Each webpage profile reflecting a webpage describes how the webpage is interpreted by the domain ontology, while a website profile describes how a website is interpreted by the ontology based on the semantics of the contained webpages. In short, the former contains basic information, statistics information, and ontology information for each webpage stored in a website model, while the latter contains basic information of a website. The website models are closely connected to the domain ontology, which supports the following functions used in website model construction and application: query expansion, webpage annotation, webpage/website classification, and focused collection and retrieval of domain-related and user-interested Web resources with highest satisfaction.
