Optimum polynomial retrieval functions
1989
Proceedings of the 12th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '89
We show that any approach to develop optimum retrieval functions is based on two kinds of assumptions: first, a certain form of representation for dc+ cuments and requests, and second, additional simplifying sssumptions that predefine the type of the retrieval function. Then we describe an approach for the development of optimum polynomial retrieval functions: request-document pairs (f" d",) are mapped onto description vectors Z(ft,&,), and a polynomial function of the form a" . G(Z) is
