Automatic ranking of information retrieval systems using data fusion

Measuring effectiveness of information retrieval (IR) systems is essential for research and development and for monitoring search quality in dynamic environments. In this study, we employ new methods for automatic ranking of retrieval systems. In these methods, we merge the retrieval results of multiple systems using various data fusion algorithms, use the top-ranked documents in the merged res...

A Novel Class-Based Data Fusion Technique for Information Retrieval

Data fusion in information retrieval combines the results from multiple retrieval models or document representations. The achievement of data fusion technique is dependent on the quality of the inputs; classical data fusion techniques fail to improve the retrieval if the quality of the retrieval results varies from low to high quality. In order to tackle this problem, in this paper we address t...

Information Retrieval Using Statistical Classification

In the classical information retrieval IR problem the system must nd all docu ments in a collection that are related to a topic de ned by a user s query A common approach to the IR problem is to represent documents and the query as vectors of term frequencies and rank the documents in the collection according to their inner product similarity with respect to the query When a sample of evaluated...

Adaptive data fusion methods in information retrieval

Data fusion is currently used extensively in information retrieval for various tasks. It has proved to be a useful technology because it is able to improve retrieval performance frequently. However, in almost all prior research in data fusion, static search environments have been used, and dynamic search environments have generally not been considered. In this paper, we investigate adaptive dat...

Democratic Data Fusion for Information Retrieval Mediators

Our research presented in this paper concerns the problem of fusing the results returned by the underlying systems to a mediating retrieval system, also called meta-retrieval system, meta-search engine, or mediator. We propose a fusion technique which is based solely on the actual results returned by each system for each query. The final (fused) ordering of documents is derived by aggregating t...
