Appeal 2007-1502
Application 09/929,260
A. INVENTION
The invention at issue on appeal is a semantically based file system.
(Specification ¶ 0002.) According to the Appellants, hierarchical systems of
organizing documents fail to meet the needs of computer users attempting to
access vast amounts of changing data. In providing component names for a
user, they add, conventional file systems attach no semantic significance to
the identified names. (Id. ¶ 0003.) In contrast, their invention encodes
semantic information in the names of virtual directories. (Id. ¶ 0002.)
B. ILLUSTRATIVE CLAIM
Claim 67, which further illustrates the invention, follows.
67. 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
