Abstract: A method and apparatus for indexing content. The method includes the steps of converting content to one or more context knowledge graphs, identifying one or more knowledgebase triples or entities from the one or more context knowledge graphs, for each knowledgebase triple or entity, identifying one or more knowledgebase variations thereof, and storing the one or more knowledgebase variations as a knowledgebase representation of the content in a reverse index to a non-volatile computer readable storage medium.

Abstract: A method and apparatus for extracting metadata. The method includes the steps of capturing metadata of one or more data sources, capturing metadata of one or more data sets comprising the one or more data sources, capturing metadata of one or more fields comprising one or more of the data sets, and capturing metadata of content within zero or more of the fields. The extracted metadata is stored to a non-volatile computer readable storage medium.

Abstract: A method and system for determining a degree of match between content and a search query are provided. The method includes the steps of determining a quality of recognition of a search query in accordance with a knowledge base, determining a quality of recognition of search content in accordance with a knowledge base, determining a quality of match between one or more knowledge base representations of the search query and one or more knowledge base representations of the search content, and computing a composite measure of the degree of match between search query and search content in accordance with the quality of recognition of the search query, quality of recognition of the search content, and the quality of match.

Abstract: A system and method for searching for content. The method includes the steps of receiving a user query, determining one or more search apps that can answer the user query, employing each of the one or more search apps to query one or more content sources associated with each of the one or more search apps, ranking search results, corresponding to the one or more content sources, provided by the one or more search apps, and storing the ranked search results to a non-volatile computer readable storage medium.

Abstract: A method and apparatus for organizing knowledgebase. The method includes the steps of defining a multi-level knowledgebase framework, the framework comprising a plane one capturing abstract knowledgebase that is universal across at least one of domains and applications, a plane two capturing real world knowledge base describing at least one of domains and applications, and a plane three capturing rules for at least one of recognizing, validating, invalidating and reasoning tasks. Information in different planes is maintained independent of each other. One or more elements may be connected across one or more of planes one, two and three by an information system in accordance with a context derived from an information designation.

Abstract: A method and apparatus for storing ontologies in a relational database. The method includes the steps of defining one or more instances, defining one or more concepts realized as instances, defining one or more relationships that may be employed between one or more instances, defining one or more relationships that may be employed between one or more concepts, and storing in a relational database each of the one or more instances, concepts, and relationships between the instances or concepts. One or more relationships may be indicated that do not apply to one or more pair of concepts.
