Amendment And Acquisition Of Text Knowledge Based On The Ontology

At present there are three ways acquistion of text knowledge:automatic acquistion, semi-automatic acquisition,and non-automatic acquisiton. Comparing the three ways,we decide on a more suitable way—semi-automatic acquisiotn,which guarantees the uniques, completeness and exactness of the knowledge acquired.By analysing the knowledge of conceptual ontology,we aim to acquire a perfect bank of knowledge.This paper introduces ontology into the amendment and acquisition of text knowledge, deciding on a most suitable method of knowledge acquisition through analysis and comparison.It turns the text knowledge into the normalized text knowledge through concept modification and unification algorithm, and ensures the concept description is consistent, complete, and accurate.And it turns into the knowledge base through the compiling,analysis and knowledge linking of the text knowledge.This paper introduces the characteristics of the text knowledge firstly,and illustrates that knowledge with different sources has important features,like inconsistency,knowledge of different granularity and knowledge of different precision,etc.Based on the above-mentioned problems,we put forward a kind of knowledge acquisition method based on concept-interconnection.This method is combined by two parts.The first part is the unification algorithm based on concept-interconnection, which is used to combine the same concept in order to ensure the completeness and accuracy of the concepts attribute/relation and attribute value/relation value. The second part is compiling system,which turns into knowledge base at last through compiling and analysis of the text and the connection of the knowledge.Practice shows that such a knowledge acquisition and amendment are feasible and effective.The unification algorithm can speed up the transformation process from the text knowledge to normalized text knowledge, ensure access to consistent, complete and accurate concept description,so as to improve the efficiency and quality of the text knowledge acquisition,further integrate and optimize the body and justice of the concept in order to get domainal knowledge efficiently.The development of the article involves a lot of basic knowledge, which will be introduced in chapter 2 to 4 with some examples to illustrate.
