System And Method For Providing Multi-Core And Multi-Level Topical Organization In Social Indexes
First Claim
1. A computer-implemented system for providing multi-core topic indexing in electronically-stored social indexes, comprising:
- a storage device comprising a corpus of articles each comprised of online textual materials; and
a social indexing system, comprising;
a finite state pattern for a topic filtering the articles as candidate articles, which are potentially on-topic;
similarity-based representations for on-topic and off-topic core meanings of the topic; and
a finite state modeler determining an aggregate score for each of the candidate articles using the similarity-based representations to indicate whether the candidate article is sufficiently on-topic; and
a display presenting the candidate articles ordered by their aggregate scores.

Abstract
A computer-implemented method for providing multi-core and multi-level topical organization in social indexes is provided. A corpus of articles is accessed. Each article includes online textual materials. A finite state pattern is provided for a topic that filters the articles as candidate articles, which are potentially on-topic. Similarity-based representations for on-topic and off-topic core meanings of the topic are provided. An aggregate score for each of the candidate articles is determined using the similarity-based representations to indicate whether the candidate article is sufficiently on-topic. The candidate articles are presented ordered by their aggregate scores. In a further embodiment, a hierarchy of topics is provided and used to guide the presentation of articles from subtopics, with considerations of fairness of subtopic coverage, elimination of similarity-duplicates in articles, and article freshness.

12. A computer-implemented system for providing multi-level topic indexing in electronically-stored social indexes, comprising:
-
a storage device comprising a corpus of articles each comprised of online textual materials; and a social indexing system, comprising; a plurality of levels of topics organized in a hierarchy, wherein each subsequent topic level in the hierarchy comprises one or more subtopics; and a finite state modeler initially identifying and ordering the articles under the current topic level, and recursively identifying and ordering the remaining articles under the subtopics under each subsequent topic level using criteria selected from the group comprising freshness of the article, balance of topical coverage of the articles across each of the subtopics, and elimination of similarity-duplicates of the articles under each of the subtopics; and a display presenting the articles. - View Dependent Claims (15)
