1. A system, comprising:
- a parser configured to parse a received message to identify one or more terms in the received message; and
a classifier operatively coupled to the parser, wherein the classifier is configured to;
compare the one or more terms parsed from the received message to terms in a plurality of previously received messages, wherein the previously received messages are classified in a data storage as stored classified messages with respect to two or more categories, wherein each category of the two or more categories is within a hierarchy of categories, wherein each level in the hierarchy below a topmost level further refines a category of information that is within an above level, and wherein at least one of the terms in the plurality of previously received messages is associated with at least two categories within the hierarchy of categories;
generate a plurality of scores for the received message based on the comparing, wherein each score of the plurality of scores indicates a probability that the received message is related to a particular category of the two or more categories, wherein a first score of the plurality of scores is associated with a first category of the two or more categories, and wherein a second score of the plurality of scores is associated with a second category of the two or more categories that is different from the first category and that is at a same level within the hierarchy of categories as the first category; and
identify that the received message is associated with the first category based on the first score and the second category based on the second score.

Abstract
A classifier may include logic to parse incoming content and to compare a key term in the content to stored content related to multiple prior messages, where the stored content is classified with respect to one or more categories. The logic may produce a score for the content based on the comparing, relate the score to one of the one or more categories, and produce a result based on the comparing, producing, or relating.

16. A method, comprising:
-
parsing, by one or more devices, a received message to identify one or more terms in the received message; comparing, by the one or more devices, the one or more terms parsed from the received message to terms in a plurality of previously received messages, wherein the previously received messages are classified in a data storage as stored classified messages with respect to two or more categories, wherein each category of the two or more categories is within a hierarchy of categories, wherein each level in the hierarchy below a topmost level further refines a category of information that is within an above level, and wherein at least one of the terms in the plurality of previously received messages is associated with at least two categories within the hierarchy of categories; generating, by the one or more devices, a plurality of scores for the received message based on the comparing, wherein each score of the plurality of scores, indicates a probability that the received message is related to a particular category of the two or more categories, wherein a first score of the plurality of scores is associated with a first category of the two or more categories, and wherein a second score of the plurality of scores is associated with a second category of the two or more categories that is different from the first category and that is at a same level within the hierarchy of categories as the first category; comparing, by the one or more devices, the first score to a first threshold; identifying, by the one or more devices and based on comparing the first score to the first threshold, that the received message is associated with the first category of the two or more categories; comparing, by the one or more devices, the second score to a second threshold that is different from the first threshold; and identifying, by the one or more devices and based on comparing the second score to the second threshold, that the received message is associated with the second category of the two or more categories. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
