Ontology-based QA Systems – Meta-Guide.com

Notes:

Ontology-based QA systems are artificial intelligence (AI) systems that use ontologies to represent and reason about the knowledge they have acquired from a given domain. An ontology is a formal representation of a set of concepts and relationships within a specific domain, and it provides a common vocabulary that can be used by different systems and applications to communicate and exchange information.

Ontology-based QA systems use ontologies to represent the knowledge they have acquired from a given domain, and they use reasoning algorithms to answer questions posed by users. These systems are able to provide more accurate and comprehensive answers to questions because they can use the knowledge represented in the ontology to contextualize the questions and provide relevant and specific answers.

Ontology-based QA systems can be used in a variety of applications, including natural language processing, information retrieval, and knowledge management. They are particularly useful in domains where a high degree of precision and accuracy is required, such as in medical or legal domains.
