Collecting training data using anomaly detection
First Claim
1. A method implemented by an information handling system that includes a memory and a processor, the method comprising:
- identifying an amount of instances of a first entity and a second entity co-occurring within a set of documents, wherein the set of documents correspond to a time duration;
determining whether the amount of instances exceeds a threshold;
in response to determining that the amount of instances exceeds the threshold, identifying at least one title, corresponding to the set of documents, that comprises the first entity, the second entity, and at least one connecting verb that grammatically connects the first entity to the second entity;
in response to identifying the at least one title that comprises the first entity, the second entity, and at least one connecting verb, identifying a plurality of connecting verbs within the set of documents that each grammatically connects the first entity to the second entity, wherein the at least one connecting verb is included in the plurality of connecting verbs;
in response to identifying the plurality of connecting verbs, selecting a plurality of document segments within the set of documents that comprise the first entity, the second entity, and at least one of the plurality of connecting verbs;
storing the selected plurality of document segments in the memory; and
training a relation-based classifier using the stored plurality of document segments.

Abstract
An approach is provided in which an information handling system detects a multi-entity co-occurrence anomaly within a set of documents that corresponds to an amount of times that a first entity and a second entity co-occur in the set of documents. The information handling system then determines that at least one of the documents includes a title having a verb that grammatically connects the first entity to the second entity. As such, the information handling system collects document segments from the set of documents that have the first entity, the second entity, and the connecting verb. In turn, the information handling system uses the collected document segments to train a relation-based classifier.

8. An information handling system comprising:
-
one or more processors; a memory coupled to at least one of the processors; and a set of computer program instructions stored in the memory and executed by at least one of the processors in order to perform actions of; identifying an amount of instances of a first entity and a second entity co-occurring within a set of documents, wherein the set of documents correspond to a time duration; determining whether the amount of instances exceeds a threshold; in response to determining that the amount of instances exceeds the threshold, identifying at least one title, corresponding to the set of documents, that comprises the first entity, the second entity, and at least one connecting verb that grammatically connects the first entity to the second entity; in response to identifying the at least one title that comprises the first entity, the second entity, and at least one connecting verb, identifying a plurality of connecting verbs within the set of documents that each grammatically connects the first entity to the second entity, wherein the at least one connecting verb is included in the plurality of connecting verbs; in response to identifying the plurality of connecting verbs, selecting a plurality of document segments within the set of documents that comprise the first entity, the second entity, and at least one of the plurality of connecting verbs; storing the selected plurality of document segments in the memory; and training a relation-based classifier using the stored plurality of document segments. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product stored in a computer readable storage medium, comprising computer program code that, when executed by an information handling system, causes the information handling system to perform actions comprising:
-
identifying an amount of instances of a first entity and a second entity co-occurring within a set of documents, wherein the set of documents correspond to a time duration; determining whether the amount of instances exceeds a threshold; in response to determining that the amount of instances exceeds the threshold, identifying at least one title, corresponding to the set of documents, that comprises the first entity, the second entity, and at least one connecting verb that grammatically connects the first entity to the second entity; in response to identifying the at least one title that comprises the first entity, the second entity, and at least one connecting verb, identifying a plurality of connecting verbs within the set of documents that each grammatically connects the first entity to the second entity, wherein the at least one connecting verb is included in the plurality of connecting verbs; in response to identifying the plurality of connecting verbs, selecting a plurality of document segments within the set of documents that comprise the first entity, the second entity, and at least one of the plurality of connecting verbs; storing the selected plurality of document segments in the memory; and training a relation-based classifier using the stored plurality of document segments. - View Dependent Claims (16, 17, 18, 19, 20)
