Comparison of two data fusion methods for information retrieval

Data fusion technology was initiated in the field of information retrieval around the 1990s.By using different strategies in a variety of ways to study the retrieval fusion,it can be found that the integration strategy can greatly improve the efficiency of information retrieval.In this paper,the authors focused on a common search strategy,the minimum distance square sum principle,and pointed out the optimality of the results under the linear integration principle and a mistake in information retrieval literatures.Then they analyzed the performance of fusion results based on the minimum distance sum.It is concluded that the fusion results weighted by the minimum distance sum are most approximate to the original retrieval results.Finally,the conclusion was demonstrated by some experiments.
