Abstract: The invention relates to a trough collector comprising a number of secondary concentrators, by which the solar radiation concentrated by the concentrator of the trough collector in a first direction transverse to the length thereof is concentrated in a second direction running along the trough collector, wherein the secondary concentrators each have a first, front reflecting wall and a second, rear reflecting wall which concentrate the radiation in the second direction, and wherein the secondary concentrators are arranged such as to be synchronously pivotable with one another, preferably about a respective pivot axis fixed with respect to the primary concentrator, such that as the position of the sun changes, the secondary concentrators can always be oriented in accordance with the incident radiation.

Abstract: The invention relates to a system and method for the enrichment and curation of concept, relationship, and assertion information into a multi-relational ontology. The invention includes a system enabling a curator, or other person, to verify the validity of assertions created by predetermined rules. The curator may also manually edit, delete, or add assertions to an ontology.

Abstract: The invention relates generally to a system and method for creating custom multi-relational ontologies. The invention includes a system and method for creating a master ontology and the application of one or more customizing constraints to the master ontology. Also provided are methods for creating custom ontologies using path-finding and creation of custom ontologies by applying customizing constraints to extraction, assembly, curation, and publication processes.

Abstract: The invention relates to a computer-implemented system and method for creating, editing, and utilizing one or more rules for multi-relational ontology creation and maintenance. The system may enable the creation and testing of various rules against a known “test-corpus.” The system may then utilize these various rules to extract and curate assertions into one or more multi-relational ontologies.

Abstract: The invention relates to a system and method for knowledge capture using multi-relational ontologies. The system may enable an ontology service provider to ascertain the scope of an entity's knowledge capture needs, create one or more base ontologies from publicly available sources, and incorporate the entity's private data into one or more value-added custom ontologies.

Abstract: The invention relates to a system and method for data extraction and management in multi-relational ontology creation. The system of the invention includes selecting a corpus of documents containing information relevant to a targeted knowledge domain, extracting assertions and their constituent concepts and relationships from the corpus, and storing the assertions, wherein the extraction processes may rules and utilize natural language processing.
