Index model and related search algorithms developed upon it are the fundamental issues of information retrieval, data mining and knowledge discovery. Upon doubled-sorted inter-relevant successive tree, a newly full-text index model, this paper develops a search algorithm, which remarkably improves the full-text search efficiency, and demonstrates the advantages of inter-relevant successive trees in...
To speed up queries over XML and semi-structured data, a number of structural indexes have been proposed. The structural index is usually a labeled directed graph defined by partitioning nodes in the XML data graph into equivalence classes and storing equivalence classes as index nodes. On the basis of the Inter- Relevant Successive Trees (IRST), we propose an efficient adaptive structural index,...
In the past two decades, database systems have been developed rapidly. Much research has been done about the techniques of index and retrieval. In relational database, B tree or B+ tree is used to index the structured data; in full text database, inverted list or sorted duality inter-relevant Successive Trees Model is used to index the full text. But in an integrated database, the efficiency of using...
