Abstract: A compact, easily mountable door closer, particularly suited for use in cubicles provided in public washrooms, has a pivot member mounted substantially within a hollow body but has a section projecting from the body from which a door is, in use, suspended. A biasing element is provided to bias the pivot member toward a neutral position coincident with the door being closed. As the door and thus the pivot member is displaced away from the closed or neutral position to a defined angle, the biasing element and pivot member engage to provide a limit or fully open position.

Abstract: A latch is provided for latching the doors of cubicles or stalls provided in public washrooms. The latch includes a body mounted within a cavity formed between the inner and outer door surfaces, the body rotatably mounting a spindle having a latching member mounted at one end. Biasing means in the form of one or more cam followers acting on a corresponding number of cam surfaces is provided between the body and the spindle to hold the spindle in a closed position but, once displaced from the closed position, to bias the spindle toward a fully open position.

Abstract: Methods and apparatus for use in coherent transmission and reception of optical data signals. An integrated optics block (100) for use in a coherent optical transmitter comprising: a beam splitter (102) configured to split an input light signal into first and second input light signals, to output the first input light signal for use in an optical transmitter chip and to output the second input light signal for use as a local oscillator signal; a polarization combiner (104) configured to combine first and second received modulated light signals to form an output; and a polarization rotator (106) configured to rotate the polarization of the second modulated light signal such that it is substantially orthogonal to the polarization of the first modulated light signal prior to combining.

Abstract: The invention relates to a system and method for electronic notification of multi-relational ontology dynamics. The system may include providing alerts to one or more users upon changes in the content of one or more ontologies. Alerts may be provided according to individual user profiles that may specify alert frequency, content, and/or format.

Abstract: The invention relates to the structure of an upper ontology and a system and method for utilizing an upper ontology in the creation of one or more multi-relational ontologies. The invention includes an upper ontology of predefined concept and relationship types, and a predefined set or relationships that may be used to connect particular pairs of concepts. The concept and relationship types may be dictated by the knowledge domains in which the resultant ontology is to reside. The invention may also include a hierarchy of concept types wherein the relationships that may exist between concept types is specified.

Abstract: The invention relates to a system and method for graphically displaying ontology data. The invention includes displaying assertions as concept-relationship-concept triplets. The invention also includes displaying ontologies, or parts thereof, as directed graphs capable of cyclic paths. Furthermore, the invention includes displaying ontologies, or parts thereof, in clustered cone graphs, wherein each cluster within a clustered cone graph represents a group of concepts or relationships, which share a common quality.

Abstract: The invention relates to a system and method for creating, editing, using one or more multi-relational ontologies and applying knowledge contained in one or more ontologies to one or more applications. The system may extract concepts, relationships, assertions and other information from a domain specific corpus of documents. The system may also create rule-based assertions that are then curated and published as one or more ontologies that can be used in various ways.

Abstract: The invention relates generally to a system and method for creating one or more structured multi-relational ontologies. The invention may include ontologies comprising assertions made up of concept-relationship-concept triplets. The invention may also include predefined sets of concept and relationship types as well as concept type hierarchies and concept-relationship association parameters. The invention may further include properties as concepts, synonyms of concepts as concepts, and documents or parts thereof as concepts.

Abstract: The invention relates to a system and method for parsing and/or exporting one or more multi-relational ontologies. The system may apply a set of export constraints to one or more master ontologies to produce a redacted data subset. The redacted data subset may then be exported to a specified location or application.

Abstract: The invention relates to a system and method for enabling users to explore paths between concepts in one or more multi-relational ontologies. The system may enable the selection of two or more concepts from an ontology and the tracking of paths of direct and indirect relationships between the two or more concepts. Constraints and/or algorithms may be used to pair down the paths between the selected concepts and enable a more manageable data set through which a user may navigate.

Abstract: The invention relates to a system and method for facilitating user interaction with multi-relational ontologies. The invention includes a graphical user interface for enabling user visualization and navigation through one or more multi-relational ontologies.

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 to a system and method for support of chemical data within multi-relational ontologies. The system may enable entry, storage, manipulation, search, and use of chemical structures within one or more multi-relational ontologies.

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.

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.
