A comparison of information retrieval models applied to Thai digital library

A digital library allows users to interact with information distributed over a network. These digital library systems support search and display of items from organized collections. In the historical of digital libraries, the mechanisms for retrieval are particularly significance. In this paper, the performance of three traditional models of information retrieval: the Boolean model, the vector space model and the probabilistic model are compared by implementing all algorithms and applying to search in Thai digital library. The experimental results show that the probabilistic model can outperform the Boolean model and the vector space model for information retrieval in Thai digital library.
