Patent number: 9489453Abstract: 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.Type: GrantFiled: February 19, 2016Date of Patent: November 8, 2016Assignee: International Business Machines CorporationInventors: Freddy Lorge, Matthew A. Pantland, Tom Rojahn

Patent number: 9094236Abstract: 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.Type: GrantFiled: June 11, 2008Date of Patent: July 28, 2015Assignee: International Business Machines CorporationInventors: Lars Fanebost, Tom Rojahn, Tryggve E.

Patent number: 8747115Abstract: 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.Type: GrantFiled: March 28, 2012Date of Patent: June 10, 2014Assignee: International Business Machines CorporationInventors: Freddy Lorge, Matthew A.
