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

Abstract

A document information processing apparatus includes: a retention unit that retains attention probability weight corresponding to a plurality of factor information for each users; a selection unit that selects a document, the document being inferred to be paid attention to, from a document group by using the attention probability weight of the plurality of the factor information; and a presentation unit that presents information corresponding to at least one of the plurality of the factor information used by the selection unit.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

Exemplary embodiment of the present invention will be described in detail based on the following figures, wherein:

FIG. 1 is a block diagram to show the configuration of an example of a document information processing apparatus according to an embodiment of the invention;

FIG. 2 is a functional block diagram to show an example of the document information processing apparatus according to the embodiment of the invention;

FIG. 3 is a conceptual drawing to show an example of a Bayesian network generated and used by the document information processing apparatus according to the embodiment of the invention; and

FIG. 4 is a schematic representation to show an example of attention probability weight for each piece of factor information retained for each user by the document information processing apparatus according to the embodiment of the invention.

Claims

1. A document information processing apparatus comprising: a retention unit that retains attention probability weight corresponding to a plurality of factor information for each users;a selection unit that selects a document, the document being inferred to be paid attention to, from a document group by using the attention probability weight of the plurality of the factor information; anda presentation unit that presents information corresponding to at least one of the plurality of the factor information used by the selection unit.

2. The document information processing apparatus as claimed in claim 1, which comprises: an addition determination unit that selects factor information from the factor information candidate based on a predetermined addition criterion, and that calculates the attention probability weight based on the factor information selected, and that retains the attention probability weight in the retention unit.

3. A method of document information processing comprising: retaining attention probability weight corresponding to a plurality of factor information for each users;selecting a document, the document being inferred to be paid attention to, from a document group by using the attention probability weight of the plurality of the factor information; andpresenting information corresponding to at least one of the plurality of the factor information.

4. A computer readable medium storing a program causing a computer to execute a process for estimating the attention degree for each user about a processed document, the process comprising: retaining attention probability weight corresponding to a plurality of factor information for each users;selecting a document, the document being inferred to be paid attention to, from a document group by using the attention probability weight of the plurality of the factor information; andpresenting information corresponding to at least one of the plurality of the factor information.

5. A computer data signal embodied in a carrier wave for enabling a computer to perform a process for estimating the attention degree for each user about a processed document, the process comprising: retaining attention probability weight corresponding to a plurality of factor information for each users;selecting a document, the document being inferred to be paid attention to, from a document group by using the attention probability weight of the plurality of the factor information; andpresenting information corresponding to at least one of the plurality of the factor information.
