System and method for data extraction and management in multi-relational ontology creation

A computer-implemented method for extracting data from one or more data sources for the creation of one or more multi-relational ontologies, comprising:

• providing an upper ontology that specifies, for a specific domain, a set of concept types and relationship types, a hierarchy of concept types and relationship types, a set of specific pairs of concept types, and a set of permissible relationship types that may be used to connect specific pair of concept types;
• providing a plurality of data sources;
• selecting a corpus of documents from the plurality of data sources, at least one of the documents being related to the specific domain;
• providing a set of rules relating to the creation of assertions, wherein assertions comprise a first concept, a second concept, and a relationship between the first concept and the second concept;
• extracting from the corpus of documents, in accordance with one or more of the rules from the set of rules, concepts and relationships between concepts to form rules-based assertions;
• associating evidence information with each of the rules-based assertions;
• and
• storing the rules-based assertions and evidence information in one or more databases.
