Common use of The Agreement Context Clause in Contracts

The Agreement Context. The agreement context of a provider peer consist of a subset of the common ontology, an export schema, an agreement component and a query response management component. The agreement component is used to map export schema to the corresponding concepts of the common ontology. The key components of the agreement process are the agreement units which establish mappings between the super peer's common ontology and provider peer's. Peer agreement refer to similarities measurement which consist of three steps, as follow: • Label matching is the matching based on linguistic approach. The as- sumption of this approach is the label bring the semantic term. The goal of the rst step is to create node match elements (NME) between a super peer (SP) and a provider peer (PP). One popular tool of lin- guistic analysis for semantic similarity is WordNet. Before using the WordNet, tokenization based on linguistic analysis is conducted. Word- Net is a semantic network database for English developed by Princeton University. An NME is tuple < mID, NPP , NSP , RSC >; where mID is a unique ID of NME, NPP is a node element of the provider peer, NSP is a node element of the super peer , RSC is value of semantic similarity between [0.1]. Result of similarity, agreement units are created to establish di erent matching on the di erent type of elements of an ontology. An agreement unit is represented by a tuple: < SMCID, ESPPi, typePPi, COSPj , typeSPj , tansCP >; where SMCID is a unique ID, ESPPi is an element of the export schema of PP, typePPi is type the export schema element of PP, COSPj is an element of the common ontology of SP,typeSPj is the type of the common ontology element,tansCP is a tansformation function between an export schema and a common ontology. The tansCP can be a derivation mapping (class and property), an operation or constraint mapping (instances). The agreement process is mainly concerned with the resolution of syntactic and semantic heterogeneity.
