| Abstract(in English) | In some intelligent application of text retrieval, it is required to do a search just through particular parts of target text data with consideration for some properties that the text have. Namely, the texts are followed by additional information, and the each target part satisfies a certain condition on it. In this paper, we address the problem to construct an efficient index structure for this kind of search. In 2006, Amir et al. proposed a modified suffix tree for this problem, called the property suffix tree, which stores only substrings that belong to the given property. This algorithm constructs a suffix tree at first, and then pluning edges indicating substrings which are not included in the property. In this paper, we present an algorithm for finding all borders between nodes to be remained and nodes to be eliminated in the suffix tree. |
