On the web, Ontology is manifested as a classification method and a group of reasoning rules.
In computer science, we narrowly think he regard him as a conceptual description of a certain field. A typical Ontology contains the hierarchical concept system in the field, and through the property-value mechanism to portray the concept, in a sense, he is a domain-specific knowledge representation.
Today's information is different from different places, the capacity is huge, and the content is also very different, which is inconvenient for people to acquire, understand, and use this information. Use Ontology to allow information to use concepts to use concepts to use concepts to strike and structure it into a knowledge system. Helps high-level applications for information processing, sharing, reuse on the web basis.
In the field of search, it can further improve the accuracy of the search and help people learn and expand search content.

For web search, through the definition of the body, the search program can perform a concept-based precise search rather than a fuzzy keyword method.
