Document data analysis apparatus, method of document data analysis, computer readable medium and computer data signal

Abstract

A document data analysis apparatus, the document data analysis apparatus being connected to a database storing plural document groups which a citation relationship is defined, each of the plural document groups including plural documents, includes: inputting unit that inputs an analysis condition including at least one of a document search condition and a specification of a seed document group, the seed document group being a seed of an active propagation process; determining unit that determines an initial active value of each of plural documents based on the analysis condition; executing unit that executes the active propagation process based on the initial active value and the citation relationship; and display that displays a result of the active propagation process.

Claims

1. A document data analysis apparatus, the document data analysis apparatus being connected to a database storing a plurality of document groups which a citation relationship is defined, each of the plurality of document groups comprising a plurality of documents, comprising: inputting unit that inputs an analysis condition comprising at least one of a document search condition and a specification of a seed document group, the seed document group being a seed of an active propagation process;determining unit that determines an initial active value of each of the plurality of documents based on the analysis condition;executing unit that executes the active propagation process based on the initial active value and the citation relationship; anddisplay that displays a result of the active propagation process.

2. The document data analysis apparatus as claimed in claim 1 wherein the display displays a document group satisfying a linkage condition so that the document group satisfying the linkage condition can be distinguished from other document groups.

3. A Method of document data analysis comprising: inputting an analysis condition comprising at least one of a document search condition and a specification of a seed document group, the seed document group being a seed of an active propagation process;accessing a database storing a plurality of document groups which a citation relationship is defined, each of the plurality of document groups comprising a plurality of documents;determining an initial active value of each of the plurality of documents based on the analysis condition;executing the active propagation process based on the initial active value and the citation relationship; anddisplaying a result of the active propagation process.

4. A computer readable medium storing a program causing a computer to execute a process for analyzing a relationship between a plurality of document groups which a citation relationship is defined, each of the plurality of document groups comprising a plurality of documents: inputting an analysis condition comprising at least one of a document search condition and a specification of a seed document group, the seed document group being a seed of an active propagation process;accessing a database storing the plurality of document groups;determining an initial active value of each of the plurality of documents based on the analysis condition;executing the active propagation process based on the initial active value and the citation relationship; anddisplaying a result of the active propagation process.

5. A computer data signal embodied in a carrier wave for enabling a computer to perform a process for analyzing a relationship between a plurality of document groups which a citation relationship is defined, each of the plurality of document groups having a plurality of documents: inputting an analysis condition comprising at least one of a document search condition and a specification of a seed document group, the seed document group being a seed of an active propagation process;accessing a database storing the plurality of document groups;determining an initial active value of each of the plurality of documents based on the analysis condition;executing the active propagation process based on the initial active value and the citation relationship; anddisplaying a result of the active propagation process.
