A Logic File System

Abstract
On the one hand, hierarchical organizations are rigid in the sense
that there is only one path to each document. On the other hand,
keyword-based search is flexible because many sets of keywords may
lead to the same document, but it lacks a navigation mechanism. We
present the new paradigm of a logic file system, which
integrates navigation and classification, and the possibility of
expressive queries. This paradigm associates logical descriptions to
files, and logical deduction serves as a basis for navigation and
querying; paths are formulas. A key notion is the extension of
a logical formula: i.e., the set of all files whose description
satisfies the formula. The root directory is determined by formula
, and
sub-directories of a directory are determined by formulas whose
extension strictly intersects the directory extension. This gives a
logical ground for considering navigation as computing relevant
hints to help refining a query.
A prototype implementation demonstrates encouraging performances.
