System and method for using banded topic relevance and time for article prioritization
First Claim
1. A computer-implemented method for using banded topic relevance and time for article prioritization, comprising:
- maintaining articles of digital information and at least one social index comprising topics that each relate to one or more of the articles;
retrieving fine-grained topic models matched to the digital information for each topic;
succinctly classifying the articles under the topics by testing the articles against the fine-grained topic models;
for each topic in the at least one social index, maintaining a coarse-grained topic model comprising;
specifying characteristic words extracted from the articles identified by the fine-grained topic models of each topic; and
assigning scores to the characteristic words;
for each of the articles within the topic under which the article was classified, accumulating the scores of the characteristic words into a relevancy score for that article;
selecting only the articles within the topic having relevancy scores satisfying a minimum threshold relevancy;
for each topic in the at least one social index, arranging the selected articles into discrete bands with each discrete band representing comparable levels of relevancy, comprising;
setting a range of relevancy scores for each discrete band; and
classifying each of the articles within the topic into the discrete band within whose range of relevancy scores the article'"'"'s relevancy score falls;
temporally sorting the articles within each of the discrete bands; and
presenting the temporally-sorted articles within the discrete bands.

Abstract
A system and method for using banded topic relevance and time for article prioritization is provided. Articles of digital information and at least one social index are maintained. The social index includes topics that each relate to one or more of the articles. Fine-grained topic models matched to the digital information for each topic are retrieved. The articles are succinctly classified under the topics using the fine-grained topic models. Each of the articles is relevancy scored within the topic under which the article was classified. The articles are arranged into discrete bands by relevance score. The articles are temporally sorted within the discrete bands. The articles are presented within the discrete bands.

8. A computer-implemented system for using banded topic relevance and time for article prioritization, comprising:
-
an electronic database, comprising; articles of digital information and at least one social index comprising topics that each relate to one or more of the articles maintained for social indexing; and fine-grained topic models matched to the digital information for each topic; a processor and memory within which code for execution by the processor is stored, further comprising; a fine-grained classifier module succinctly classifying the articles by testing the articles against the topics using the fine-grained topic models; a coarse-grained classifier module configured to maintain, for each topic in the at least one social index, a coarse-grained topic model, comprising; an extraction module configured to specify characteristic words extracted from the articles identified by the fine-grained topic models of each topic; and a scoring module configured to assign scores to the characteristic words; a relevancy scoring module configured to accumulate, for each of the articles within the topic under which the article was classified, the scores of the characteristic words into a relevancy score for that article; a selection module configured to select only the articles having relevancy scores satisfying a minimum threshold relevancy; a band module configured to arrange, for each topic in the at least one social index, the selected articles into discrete bands with each discrete band representing comparable levels of relevancy, comprising; a range of relevancy scores for each discrete band; and a discrete band classifier configured to classify each of the articles within the topic into the discrete band within whose range of relevancy scores the article'"'"'s relevancy score falls; and a temporal module temporally sorting the articles within each of the discrete bands; and a user interface visually presenting the temporally-sorted articles within the discrete bands. - View Dependent Claims (9, 10, 11, 12, 13, 14)
