The answer extraction is an important step in Q&A System and other fields of the Natural Language Processing; the result of answer extraction is directly associated with the quality of Q&A System. In this paper, the method, answer extraction of simple question based on web knowledge library, is realized through computing the similarity of simple question; the question with the most similarity...
Similarity computing of question is one of the important basis issues in the field of natural language processing, which was widely used in the Q&A system, and other areas such as question classification. In this paper, a method is presented that the keywords are extracted and then the similarity of keywords is calculated, and the similarity of sentences is the weighted average of similarity between...
The hexagonal cadmium sulphide (CdS) thin films with strong (002) orientation are successfully prepared by chemical bath deposition (CBD) technique using the reaction between CdCl 2 and CS(NH 2 ) 2 . Especially, polyglycol is used to modify the CBD system without magnetic agitation. The influence of bath temperature on the properties of the CdS films such as optical transmission,...
