exploration of term dependence

... such term based matching approaches. Term dependence, which means that the pres- ence or absence of one set of terms provides in- formation about the probabilities of the presence or absence of ... syntactic relationships of terms. For that the syntactic relationships can happen among any set of query terms, hence the assump- tion of dependence occurring among any query terms is considered ... de- pendences among query terms and different ap- proaches have been proposed to define the styles of term dependence in query. In this paper, the assumption of term dependence starts by consid- ering...
