Abstract
Official abstract text for this publication.
An offline adaptation method of customizing and incorporating external knowledge domain specific knowledge sources into an existing knowledge base (KB) of a cognitive conversation system, includes obtaining an instance-concept frequency from the existing KB. All the contexts of a domain ontology in which an instance-concept is used are computed. All instance-concepts from the existing KB to an external domain-specific knowledge source are mapped. The existing KB is configured to search for semantically related terms in response to a natural language query received from a conversation system.
First claim
Opening claim text (preview).
What is claimed is: 1 . An offline adaptation method of customizing and incorporating external knowledge domain specific knowledge sources into an existing knowledge base (KB) of a cognitive conversation system, the method comprising: obtaining an instance-concept frequency from the existing KB; computing all the contexts of a domain ontology in which an instance-concept is used; and mapping all instance-concepts from the existing KB to an external domain-specific knowledge source, wherein the existing KB is configured to search for semantically related terms in response to a natural language query received from a conversation system. 2 . The method according to claim 1 , further comprising: adjusting the instance-concept frequency based on a quantity of documents in which the instance-concept appears. 3 . The method according to claim 1 , wherein the external domain-specific knowledge source includes data in a form of at least one of taxonomies, ontologies, or semantic networks. 4 . The method according to claim 1 , further comprising ingesting the external domain-specific knowledge source into a graphic database. 5 . The method according to claim 1 , wherein the external domain-specific knowledge source is grouped in terms of concept, relation, and description. 6 . A non-transitory computer readable storage medium tangibly embodying a computer readable program code having computer readable instructions that, when executed, cause a computer device to execute a method of customizing and incorporating external knowledge domain specific knowledge sources into an existing knowledge base (KB) of a cognitive conversation system, the method comprising: obtaining an instance-concept frequency from the existing KB; computing all the contexts of a domain ontology in which an instance-concept is used; and mapping all instance-concepts from the existing KB to an external domain-specific knowledge source, wherein the existing KB is configured to search for semantically related terms in response to a natural language query received from a conversation system. 7 . The non-transitory computer readable storage according to claim 6 , further comprising: adjusting the instance-concept frequency based on a quantity of documents in which the instance-concept appears. 8 . The non-transitory computer readable storage according to claim 6 , wherein the external domain-specific knowledge source includes data in a form of at least one of taxonomies, ontologies, or semantic networks. 9 . The non-transitory computer readable storage according to claim 6 , further comprising ingesting the external domain-specific knowledge source into a graphic database. 10 . The non-transitory computer readable storage according to claim 6 , wherein the external domain-specific knowledge source is grouped in terms of concept, relation, and description.
