A System and Method of Identifying Nearby Locations in a Cognitive System

Disclosed is a system and method for identifying nearby locations in cognitive systems or question answering system.

In the discovery task, a question answering system is sometimes given vague geographic information. For example: "What are the IS strongholds that are near Baghdad?" The source documents may not contain sentences similar to "Fallujah is an IS stronghold, which is near Baghdad." A source document is more likely to have a

sentence similar to: "Fallujah is an IS stronghold in Anbar Province." The user is expected to understand that Anbar Province is near Baghdad and that the sentence is relevant.

The disclosed method assigns geographical coordinates to passage entities, and treats them as synonyms of question entities based on their proximity. For example, in the example, "Anbar Province" would be replaced with the latitude/longitude coordinates of

Anbar Province. Baghdad (in the question) would also be replaced with Anbar

Province, with a weight based on how far it is from Baghdad. In the case of two geographical locations that are very close, the weight would be close to 1. For very distant locations, the weight would be close to 0.

Consider the question: "What universities are located around Columbus, Ohio?"

Consider further the passages:


Passage 1: "Dennison University is located in Granville." Passage 2: "Damascus University is located in Syria."

Granville is a village about 35 miles east of Columbus Ohio, while Syria is a distant

country. With a naive approach to scoring these passages, they could have equivalent or nearly equivalent scores. In both cases, the passages have the same phrasing, and after abstracting the candidate answer differ only in th...
