Automated propagation of document metadata
First Claim
1. A computer-implemented method of conditionally propagating metadata among documents comprising:
- defining a plurality of groups of metadata instances;
assigning a plurality of propagation coefficients to each said group, where each said propagation coefficient assigned to each said group is associated with at least one document attribute and is based upon correlating said associated document attribute with determinations of document-to-document propagations of said metadata instances of said group;
selecting first and second documents between which a specific metadata instance may be propagated, said first and second documents being stored in memory;
basing metadata propagation from said second document to said first document upon a plurality of said document attributes, including(a) determining a particular said group in which said specific metadata instance resides;
(b) for each of said document attributes upon which said metadata propagation is based, identifying said associated propagation coefficient that was assigned to said particular group; and
(c) for each of said document attributes upon which said metadata propagation is based;
comparing said first and second documents with respect to said document attributes; and
on a basis of said document attributes, selectively propagating said specific metadata instance to said first document for storage in said memory.

Abstract
An automated method for conditionally propagating metadata instances among documents includes defining groups of metadata instances and includes assigning different propagation coefficients to each group. Each propagation coefficient assigned to a particular group is based upon correlating the associated document attribute or attributes with reliable propagations of metadata instances within the group. After the groups of metadata instances have been defined and the propagation coefficients have been assigned, propagation of a metadata instance from a second document to a first document is based upon a combination of (1) determining the particular group in which the metadata instance resides, (2) identifying the propagation coefficients that are assigned to that group for the associated document attributes, and (3) comparing the first and second documents with respect to the associated document attributes.

12. A computer-implemented method for propagating metadata instances of a particular metadata type comprising:
-
grouping said metadata instances in accordance with similarities among corresponding document attributes of training documents with which said metadata instances are associated; for each grouping of metadata instances, assigning correlation coefficients to relevant said document attributes, where said correlation coefficients are computed based on correlations between said grouping of metadata instances and individual said relevant document attributes; and propagating specific metadata instances to various second documents based on said groupings and on said correlation coefficients, said propagating being further based upon; (a) source weightings of said specific metadata instances as applied to source documents from which said specific metadata instances are to be propagated, said source weightings being representative of a perceived confidence in attachments of said specific metadata instances to said source documents; and (b) calculating a metadata weighting when a particular metadata instance is propagated from a source document to a particular said second document, said metadata weighting representing factors that include similarities between said source document and said particular second document, wherein calculating said metadata weighting (myg) when said particular metadata instance is propagated from said source document (x) to said particular said second document (y) includes factoring; (1) said source weighting (mxg) of the source document from which said particular metadata instance is propagated; (2) said correlation coefficients for said grouping (g) in which said particular metadata instance resides, said correlation coefficients being propagation coefficients (α
(c, g)) for said relevant document attributes (c) selected for said grouping; and(3) similarities (Sc(x, y)) between said source and said particular said second document with respect to said relevant document attributes selected for said grouping. - View Dependent Claims (13, 14, 15, 16)
