  • Patent number: 8924340
    Abstract: A method according to the present invention enables the similarity between sequences of symbols to be determined using rules generated from a dictionary-based compression scheme according to the content of the columns from databases. Pairs of symbols can replaced by rules that do not comprise a repeated combination of two symbols and where each rule occurs more than once in the sequence of symbols. The similarity of each set of rules can then be expressed numerically.

  • Publication number: 20130290338
    Abstract: A system (100) for generating a computer readable data file representative of a mapping between a first representation of a set of concepts or of a data structure (e.g. a database schema) and a second representation of a set of concepts or of a data structure (e.g. an ontology), each representation comprising a plurality of complex representational elements (e.g. tables in a database schema and concepts in an ontology) each of which may itself include a number of associated subordinate representational elements (e.g. columns/fields of a table in a database schema and attributes of a concept in an ontology).

  • Patent number: 8433566
    Abstract: Video material is dividing into temporal segments. Each segment is examined to determine whether the soundtrack of the segment contains speech sufficient for analysis and if so, metadata are generated based on analysis of the speech. If not, the segment is analysed by comparing frames thereof with those of stored segments that already have metadata assigned to them. One then assigns to the segment under consideration stored metadata associated with one or more stored segments that are similar.

  • Patent number: 8375029
    Abstract: A system for processing data comprising: a plurality of resource interfaces each of which is operable to access a corresponding underlying resource, and a processor unit for integrating data accessed from the underlying resources and controlling a user interface. The user interface is operable in use to permit a user to view all of the underlying resources currently accessible to the system and to select a plurality of these to form a subset comprising some, but not all, of the underlying resources from which to form an integrated view of the sub-set. The processor unit is operable to store the selection within a user selection store and to determine how to join the data from the selected underlying resources to generate an integrated view of the selected sub-set of underlying resources and to generate data for transmission to a device for displaying the generated view to the user.

  • Publication number: 20100106701
    Abstract: An electronic document retrieval system is disclosed. It has particular utility to World-Wide Web searching. The system requires webmasters to put forward categories into which the pages on their web-site might sensibly be divided, and to provide a list of those categories together with a list of popular keywords associated with those categories to a global search engine. The global search engine is then able to augment one or more of its search results with links to category-heading pages which most closely relate to the query provided by the user. In this way, a user is able to find the page most relevant to his query more rapidly than has hitherto been possible.

  • Publication number: 20100049762
    Abstract: An electronic document retrieval system is disclosed. It has particular utility to World-Wide Web searching. In contrast to conventional search engines, when providing supplementary results in addition to primary results, the system enables the supplementary results to include links to documents in web-sites other than the web-site to which the primary result belongs. In this way, a user is able to find the page most relevant to his query more rapidly than has hitherto been possible.

  • Publication number: 20080235203
    Abstract: A method and apparatus are provided for accessing a relevant information resource in response to a user query. An ontology is provided, defining relationships between a plurality of predefined concepts, and between each of the predefined concepts and one or more predefined context phrases. On receipt of a user query, portions of the received query are compared with the context phrases to identify one or more matching phrases and hence, from the predefined relationships with concepts in the ontology, one or more relevant concepts. Concepts identified in respect of the received user query are used to identify a relevant action using predefined relationships between concepts in the ontology and predefined actions, wherein an action comprises providing access to an information resource.

  • Publication number: 20070055948
    Abstract: tool providing a graphical user interface with underlying intelligence to assist a user in creating mappings between ontologies or between ontologies and database schema. For each individual mapping which a user makes the tool checks that the proposed mapping is consistent with all other proposed mappings made by the user thus far and alerts the user if an inconsistency is detected.

  • Patent number: 7177852
    Abstract: A method for knowledge representation and management is disclosed which has particular but not exclusive application in knowledge recovery techniques. To help with program understanding, software maintainers use computer aided reverse engineering (CARE) tools which utilize techniques such as syntax analysis, structural analysis, and domain knowledge base analysis (DKBA). Known DKBA methods are complex since the domain knowledge recovery relies on the use of knowledge at different layers while some elements of the knowledge at domain level is not used at all. In the disclosed method for representing knowledge in a knowledge base, the knowledge is represented by a set of one or more concepts and by one or more first type of relationships between two or more or said concepts.

  • Patent number: 7155715
    Abstract: A data management system stores and visualizes data generated during process management. The data management system provides different data management services and definitions of these are stored in a database. Management of data in this database is carried out by a collection of software agents, one of which, the management information agent, can access, update and download data in or from the database. Stored separately are graphical user interfaces which are downloaded to a user in accordance with the relevant service definition stored in the database when the user requests a particular data access service.

  • Publication number: 20040243595
    Abstract: A database management system comprising a plurality of database resources (12, 14, 16) includes a query engine (30) which parses incoming queries into sub-queries directed at respective resources, (12, 14, 16) and compiles the sub-results into a final result. A node and a link representation is used to associate values from a different resources to address problems of semantic mismatch. In addition, ontologies are compiled for each resource against a shared ontology and a user/application ontology. As a result of the system, problems of semantic mismatch and query integration against distributed resources is overcome.

  • Publication number: 20040083223
    Abstract: A database management systems is disclosed for solving distributed queries across a range of resources. In known systems, database retrieval from multiple sources suffers from problems of reconciliation of data between resources and resource or data incompatibility. The invention allows full database integration even in the case where a database includes a plurality of disparate database resources having differing ontologies (data structures). The system has an ontology server which is used to store the ontologies of various database resources and the query engine is designed to consult the server so that it can construct a query that will operate effectively across the disparate database resources.

In known systems, database retrieval from multiple sources suffers from problems of reconciliation of data between resources and resource or data incompatibility. The invention allows full database integration even in the case where a database includes a plurality of disparate database resources having differing ontologies (data structures). The system has a complex query analysis system that is arranged to find and link all database resources having the required elements for a specific database query. This then enables the query to be processed more efficiently.
