Modification of Keyword Selection Process to Get Least List with Weighted Keywords by using Essence of both ‘Baxendale’ and ‘Swanson’ Experiment

Abstract

The 'keyword-based search system' by its name implies that the document is presented with the correct keyword. Keyword-content relations need to be thoroughly analyzed in order to select a document's keywords. In this case, the current method used, even after the use of ontology, has not been adequate. That's why many keywords are being selected for a particular document. And users are bounded to use all those keywords in search of a single document, resulting in a decrease in the precision of retrieval day by day. So in this case it is not possible to get high precision and to reduce quantity of keywords without selecting high quality keywords. The purpose of this paper is to examine how informative a particular keyword is, and to select the highest and most informative keyword and to exclude the least informative keyword through which, 'keyword-based search system' can get fewer but higher quality or weighted keywords as a helping hand to solve 'High Recall and Low Precision'.

Utilization and Application of Weighted Keyword in Retrieval

“…Because of the combination of these two, one of the methods is complete. Therefore, there is a need to explain the practical side of the 'Grammatical-Hierarchical Logic' method (1) in a scientific way. The keyword's weight can be used to determine the importance or the internal value of that keyword, thus creating an opportunity to reduce the amount of keyword.…”

“…And this can only be done by improving the quality of the keyword like 'Weighted Keyword'. As a result the precision will increase (1). By the 1950, computer usage in data storage began to increase.…”

“…Keyword selection, content analysis is also required. This is the main background of the selection of weighted keyword by 'Grammatical-Hierarchical Logic' method (1). Document retrieval (9) can be much more precise by using the weighted keywords.…”

The Impact of Relative Keyword Indexing System Instead of KWIC Indexing System on Retrieval

“…of keyword (core element for recall). (3) 'Keyword based search system' has some problem to identify the exact user intent documents by using KWIC indexing system. These are-non informative keywords, scattering of related terms, and scattering of related documents.…”
