Automatic Extraction of Ontology Attribute Value Based on WWW

Attributes value is among the most important information to describe Ontology.However,few researches have been done about attribute values extraction so far.This paper proposes a method of extracting Ontology attribute values automatically based on WWW.Firstly,an interactive method is described to unilize the interaction between the attribute-value-related sentence selection and the attribute values extraction.This method can expand the target attribute value set from a seed set by the redundancy of WWW.Secondly,we present a method to construct the seed automatically.Experiments are conducted to examine the method in terms of precision and recall.In addition,automatically enriched Ontology information is applied in webpage content extraction to test the usefulness of our approach.
