In statistical machine translation, the number of sentence pairs in the bilingual corpus is very important to the quality of translation. However, when the quantity reaches some extent, enlarging corpus has less effect on the translation, whereas increasing greatly the time and space complexity to building translation systems, which hinders the development of statistical machine translation. In this...
Traditional retrieval models assume that the relevance of a document is independent of the relevance of other documents. However, this assumption may result in high redundancy and low diversity in a ranked list. In order to provide comprehensive and diverse answers to fulfill biologists' information need, we propose a relevance-novelty combined model, named RelNov model, based on the framework of...
Recently, Xiao et al. proposed a digital signature scheme (XWS scheme) based on the conic curve over Zn and claimed that the security relied on both of the factorization and the discrete logarithm. However, there is a flaw in the XWS scheme, where the modulus n can be factorized easily. This flaw shows that the XWS scheme is not a scheme whose security based on integer factorization problem. To address...
Previous research has shown that using term relationships within language model could improve the effectiveness of information retrieval. But all models only consider adjacent relation or distant relation, none of them combine the two types relation. So in this paper, we propose a new dependency language model for improving information retrieval. In our model, phrases and co-occurrence terms are integrated...
