  • Patent number: 9489453
    Abstract: An approach for building an ontology is provided. Syntactically transformed complex triples whose core terms are identified are semantically transformed into simplified triples referring to new conceptualized core terms formed by user selections from a lexical database or by adding a suffix to core terms. The core terms are assigned to respective definitions and keys in a reference ontology, thereby retaining the semantics of the complex triples. Based on the reference ontology, an enrichment transformation of the simplified triples is performed to create simplified and enriched triples by adding relations derived from a correspondence each term in the simplified triples has with the reference ontology and by adding representations of semantics of reference ontology definitions of the terms. The simplified and enriched triples are stored as an ontology representing knowledge in an application providing free-form text from which the complex triples were extracted.

  • Patent number: 9094236
    Abstract: A method, system and computer program product for collaborative filtering of junk electronic mail (e-mail) are provided. The method includes receiving an e-mail message at a service provider, where the e-mail message includes a source address and a recipient address. The method further includes searching a collaborative junk register (CJR) for the recipient address in a group member list, where the group member list includes multiple member addresses and a junk address. The method additionally includes comparing the source address to the junk address. The method also includes filtering the e-mail message at the service provider to prevent delivery of the e-mail message in response to locating the recipient address in the CJR and identifying source address as the junk address.

  • Patent number: 8747115
    Abstract: An approach for building an ontology is provided. Based on a grammar, extracted complex triples are syntactically transformed to identify core terms. The syntactically transformed complex triples are semantically transformed into simplified triples referring to new terms that conceptualize the core adjectives, adverbs and verbs, and assigning the core terms to respective definitions and keys in a reference ontology, thereby retaining the semantics of the complex triples. Based on a meta-schema of the reference ontology, an enrichment transformation of the simplified triples is performed to create simplified and enriched triples by adding relations derived from a correspondence each term in the simplified triples has with the reference ontology and by adding representations of semantics of reference ontology definitions of the terms. The simplified and enriched triples are stored as an ontology representing knowledge in an application providing the free-form text from which the complex triples were extracted.

  • Publication number: 20070070890
    Abstract: A dynamic bandwidth manager for determining the bandwidth available to an IP connected client device, the IP connected client device requesting access to multimedia resources from a service provider, the dynamic bandwidth manager comprising: a receiving component for receiving an IP address of an IP connected client requesting access to a resource; a requesting component for locating a nearest managed device to the IP connected client and requesting a current network management data set pertaining to the IP connected client from the located managed device; a calculation component for retrieving a previously stored set of network management data pertaining to the IP connected client and for analysing the network management data sets, in dependence on the current network management data set and the previously stored network management data sets, to calculate the available bandwidth capacity of the IP connected client.
