This paper proposes a non-segmented document clustering method using self-organizing map (SOM) and frequent max substring mining technique to improve the efficiency of information retrieval. The proposed technique appears to be a promising alternative for clustering non-segmented text documents. To illustrate the proposed technique, experiment on clustering the Thai text documents is presented in this paper. The frequent max substring mining technique is first applied to discover the patterns of interest called Frequent Max substrings or FM from the non-segmented Thai text documents. These discovered patterns are then used as indexing terms, together with their number of occurrences, to form a document vector. SOM is then applied to generate the document cluster map by using the document vector. As a result, the generated document cluster map can be used to find the relevant documents according to a user's query more efficiently.
