System and method for determining the desirability of video programming events using keyword matching
First Claim
1. A method in a programmable computing device for determining the desirability of programming events, the method comprising executing processing comprising:
- receiving metadata describing programming events, the metadata that describes a programming event being comprised of at least one of descriptive data and keyword data;
determining a keyword match score for each programming event having a keyword match, wherein a keyword match is a match of the at least one of descriptive data and keyword data of the programming event metadata and a keyword of the at least one viewer profile, andranking the programming events in accordance with the keyword match scores for each programming event;
wherein the metadata for a programming event further comprises goodness of fit scores associated with respective subject matter categories, wherein a goodness of fit score represents the degree to which the corresponding category is descriptive of the subject matter of the programming event;
wherein the method further comprises determining a category match score for each programming event as a function of the metadata goodness of fit scores and viewer profile preference scores of matched categories of the programming event, wherein a matched category is a category for which there is a goodness of fit score in the metadata of the programming event and a preference score in a viewer profile; and
wherein said ranking is performed in accordance with the keyword match scores for each programming event and the category match scores for each programming event.

Abstract
The desirability of programming events may be determined using metadata for programming events that includes goodness of fit scores associated with categories of a classification hierarchy one or more of descriptive data and keyword data. The programming events are ranked in accordance with the viewing preferences of viewers as expressed in one or more viewer profiles. The viewer profiles may each include preference scores associated with categories of the classification hierarchy and may also include one or more keywords. Ranking is performed through category matching and keyword matching using the contents of the metadata and the viewer profiles. The viewer profile keywords may be qualified keywords that are associated with specific categories of the classification hierarchy. The ranking may be performed such that qualified keyword matches generally rank higher than keyword matches, and keyword matches generally rank higher than category matches. In alternative embodiments, scores may be calculated such that the ranges of scores for qualified keyword matches, keyword matches and category matches are overlapping but are generally ordered as previously described. Related embodiments may pertain to systems that implement such methods. Program rankings may be used to generate an alert schedule for providing alerts to viewers regarding programming events.
