In this paper, we propose a new method for measuring the similarity between two short text snippets by comparing each of them with the probabilistic topics. Specifically, our method starts by firstly finding the distinguishing terms between the two short text snippets and comparing them with a series of probabilistic topics, extracted by Gibbs sampling algorithm. The relationship between the distinguishing...
Ontology-based information retrieval is an effective approach to achieve knowledge retrieval. For retrieving more efficiently in the uncertain information space, a method of rough ontology-based information retrieval is proposed. Given a query keyword, the method can compute individuals and query properties by a search procedure, and construct approximation space in ontology information system by...
