Report on the TREC-5 Experiment: Data Fusion and Collection Fusion
نویسندگان
چکیده
This paper describes and evaluates a retrieval model that considers the problem of data fusion and collection fusion as two faces of the same coin. To establish a clear theoretical foundation for combining various sources of evidence provided either by different search schemes (data fusion) or by distributed information services (collection fusion), we have implemented a retrieval model based on the logistic regression methodology.

متن کاملPerformance evaluation of various data fusion methods
Data fusion is the combination of the results of independent searches on a document collection into one single output result set. It has been shown that this can greatly improve retrieval effectiveness over that of the individual results. This paper compares some major data fusion and system selection techniques by experimenting on TREC ad hoc collections.

متن کاملApplication of Data Fusion in the Web Track
In this paper, we report on the experiments we conducted whilst participating in the TREC 2013 Web track. We use data fusion to test how to improve the results from different information retrieval systems. Linear combination is used for fusion and multiple linear regression is used to obtain suitable weights for all the component systems involved. In our experiments, the ClueWeb09 dataset is us...
