Abstract:

This article discusses and describes a Document Ranking OPTimization (DROPT) algorithm for information retrieval (IR) in a web-based and designated databases environment. Specifically, the technique was first borne out in Agbele 2014. Conversely, as the volume of information available online and in designated databases is growing continuously, ranking algorithms can play a major role in the context of search results. In this paper, a DROPT technique for documents retrieved from a corpus is developed with respect to document index keywords and the query vectors. This is based on calculating the weight (wij) of keywords in the document index vector, calculated as a function of the frequency of a keyword kj across a document di. The purpose of DROPT technique is to reflect how human users can judge the context changes in IR result rankings according to information relevance. Our technique for IR optimization is generic for ranking retrieved documents. This article found out that it is possible for DROPT technique to overcome some of the limitations of existing traditional (tf x idf) algorithms via adaptation. We believe this technique can improve individual usersâ?? retrieval performance with promising results.
