Chinese text similarity calculation plays an important role in the Chinese information processing field. This paper uses ontology to calculate text similarity. The ontology has been widely used in natural language processing. Its unique concept model on the relationship offers a new processing method for word similarity calculation. Based on the characteristics of ontology and combined with HowNet...
Aiming at the disadvantages of the word segmentation method based on string matching, the word segmentation method based on comprehension and the word segmentation method based on statistic, a novel field word segmentation model based on ontology was studied. With ontology technology introduced into Chinese word segmentation, the novel model eliminates ambiguities to a great extent and avoids semantic...
Aim at the problem of poor retrieval quality in digital library, the advantage and correlative application of the ontology in digital librarypsilas semantics retrieval fields was introduced. Then basic structure of semantics retrieval system based on ontology was put forward, and the ontology of constructing scientific documents was presented. Further, the process of intelligent retrieval system based...
