Abstract:
1. A computer implemented information retrieval system for returning a semantically dependent directory structure of files to a user, comprising: a file system engine, that receives a file request via a file system application programming interface, wherein said file request specifies a file content of memorized files; a parser, linked to said file system engine, that retrieves structural information of documents, said parser further retrieving at least one of elements, attributes and respective values thereof from said documents; an indexer, linked to said parser, for constructing an inverted index of said elements and said attributes and said respective values thereof, wherein responsive to said file request, said file system engine retrieves postings of said inverted index that satisfy requirements of said file request, and returns a hierarchical tree of directories to said user; and wherein said file system engine returns a special virtual directory in each of said directories, wherein a content of said special virtual directory comprises at least one level of said hierarchical tree, said one level being more deeply nested than a level of said special virtual directory in said hierarchical tree.
