Layered Index Structures in Document Database Systems

In this paper, a signature file method for indexing document database systems is presented. For this purpose, the concept of presentative word hierarchy is introduced, based on which signature file hierarchies can be established. Together with the concept of query signature hierarchy, it improves significantly the retrieval efficiency of documents stored structurally in object oriented databases.
