Patent number: 10545930Abstract: Enterprises express the concepts of their electronic business-to-business (B2B) communication in differently structured ontology-like schemas. Collaborations benefit from merging the common concepts into semantically unique Business Entities (BEs) in a merged schema. Methods and systems for labeling the merged schema with descriptive, yet short and unique names, are described. A heuristically ranked list of descriptive candidate phrases for each BE is derived locally from the names and descriptions of the underlying concepts. A semantically unique candidate phrase is assigned to each BE that discriminates it from the other BEs by employing a constraint satisfaction problem solver.Type: GrantFiled: September 20, 2017Date of Patent: January 28, 2020Assignee: SAP SEInventors: Nathali Ortiz Suarez, Jens Lemcke, Gunther Stuhec

Patent number: 10417594Abstract: Methods, systems, and computer-readable storage media for evaluating a validity of an extended status and action management (SAM) schema. In some implementations, actions include receiving the extended SAM schema, the extended SAM schema being an extension of a core SAM schema, providing one or more goals, goals representing an intention of the core SAM schema, receiving one or more action chains, action chains representing one or more actions of the extended SAM schema that are to be automatically executed, the one or more actions being associated with triggerability flags, a triggerability flag indicating whether a respective action is only triggerable using a respective action chain, and processing the one or more goals, the one or more action chains and the triggerability flags using a computer-executable model checking tool for evaluating the validity of the extended SAM schema.Type: GrantFiled: May 2, 2013Date of Patent: September 17, 2019Assignee: SAP SEInventors: Jens Lemcke, Andreas Friesen, Piergiorgio Bertoli, Marco Pistore

Publication number: 20160098429Abstract: Enterprises express the concepts of their electronic business-to-business (B2B) communication in diffrently structured ontology-like schemas. Collaborations benefit from merging the common concepts into semantically unique Business Entities (BEs) in a merged schema. Methods and systems for labeling the merged schema with descriptive, yet short and unique names, are described. A heuristically ranked list of descriptive candidate phrases for each BE is derived locally from the names and descriptions of the underlying concepts.

Publication number: 20150142841Abstract: A name of one or more entity classes of the data model may be refined to conform to a naming convention. A semantic meaning of each of the names and one or more attributes of each entity class may be determined. It may be determined that the name of a first entity class is semantically similar to the name of a second entity class based on a semantic distance between the semantic meaning of the names, where a substantial similarity may be determined between the first entity class and the second entity class by comparing the semantic meaning of the one or more attributes of the first entity class to the semantic meaning of the one or more attributes of the second entity class. The data model may be normalized based on the substantial similarity.Type: ApplicationFiled: January 29, 2015Publication date: May 21, 2015Inventors: Gunther STUHEC, Florian GESSNER, Jens LEMCKE
