Get timely files from visualized structure of your working history

摘要

The presented KeyGraph for Files (KGF in short) helps user in finding timely files and their relationships to their major relevant files. KeyGraph, which was presented as a document indexing algorithm, is applied here to a history of filesaccessed by the user, in stead of to a document. This strategy of KGF is supported by analogies between a document and a history of one's using files: The occurrences of words in a document and of files used in a sequence have common causal structures,and KeyGraph previously indexed documents taking advantage of the causal structure in a document. As an effect, timely files are obtained from the history of a user's using files, in a similar manner as keywords were obtained from a document, by KeyGraph.
