Relevance similarity: an alternative means to monitor information retrieval systems

Relevance similarity: an alternative means to monitor information retrieval systems

BACKGROUND Relevance assessment is a major problem in the evaluation of information retrieval systems. The work presented here introduces a new parameter, "Relevance Similarity", for the measurement of the variation of relevance assessment. In a situation where individual assessment can be compared with a gold standard, this parameter is used to study the effect of such variation on the perform...

An alternative and flexible approach in robust information retrieval systems

In this paper, we present a flexible architecture to implement a robust information retrieval system based on domain and linguistic modelling by means of a set of conceptual probabilistic and non-probabilistic grammars. It allows certain complexity in the functionality of the application, such as applying non-SQL functions to the results of SQL queries in order to retrieve information not expli...

a cybernetic approach to information storage and retrieval systems

purpose: libraries and information centers as information storage and retrieval systems can develop with the adoption of cybernetics rules. this paper discusses system dynamics, control, feedback, and other cybernetic concepts especially in information storage and retrieval systems. methodology: this study is a review intending to find what cybernetics and lis have in common especially in the f...

Subjective Relevance: Implications on Interface Design for Information Retrieval Systems

Information retrieval (IR) systems are traditionally developed using the objective relevance approach based on the “best match” principle assuming that users can specify their needs in queries and that the documents retrieved are relevant to them. This paper advocates a subjective relevance (SR) approach to value-add objective relevance and address its limitations by considering relevance in te...
