Although OWL-S has given semantics to concepts by ontology technology, it gives no semantics to control-flow and data-flow. This paper presents a formal semantics framework for OWL-S sub-set, including its abstraction, syntax, static and dynamic seman-tics by rewrite logic. Details of a consistent transformation from OWL-S SOS of control-flow to corresponding rules and equations, and dataflow semantics including “Precondition”, “Result” and “Binding” etc. are explained. This paper provides a possibility for formal verification and reliability evaluation of software based on SOA.展开更多

Due to the fact, however, that the expressive power of horn logic is relatively limited and the mechansm ofnegation is mostly that of negation as failure, it is difficult to make full use of negative information and consequentlynot suitable for inductive learning. This Paper adopts nounal lope program as me language of inductive logic programsand presents accordingly a kind of semantics called Limited Negation semantics. The issues of direct denotation andinference of negation in concept induction are solved. The paper shows that LN is directly generalized for the semantics of Well-Founded in die significance Of optional negation and has superior theoretical features, especially the capability Of expressing and processing negation by introducing the constant ’false’. ExperimentS also show that the inductive concepts in learning are accurately interpreted with LN.展开更多

So far RSS information is mostly managed by content publishers but Internet users have less initiative to choose what they really need. More attention needs to be paid on techniques for user-initiative information discovery from RSS feeds. In this paper, a quantitative semantic matchmaking method for the RSS based applications is proposed. Semantic information is extracted from an RSS feed as numerical vectors and semantic matching can then be conducted quantitatively. Ontology is applied to provide a common-agreed matching basis for the quantitative matchmaking. In order to avoid semantic ambiguity of literal statements from distributed and heterogeneous RSS publishers, fuzzy inference is used to transform an individual-dependent vector into an individual-independent vector. Semantic similarities can be revealed as the result.展开更多

It makes a discrimination of the different aspects of meaning that the two branches of linguistics focus upon respectively. Both semantics and pragmatics are studies of the meanings of language. Semantics studies the meaning within the system of language while pragmatics studies the meaning with the speaker involved, that is to say from the social angle. Pragmatics is based on the knowledge of semantics. Given the fact that neither semantics nor pragmatics alone can solve the myth of the meaning of language, it may not be wise to make a clear cut between semantics and pragmatics.\;展开更多

In order to define fuzzy operations, i.e., fuzzy logic connectives, we take into account implicator → and its associated based on residuated lattice theory. Based on these basic fuzzy operations, we introduce the angelic and demonic updates of fuzzy relations. They are the basis of fuzzy predicate transformers in the sense of that any strongly monotone fuzzy predicate transformer can be represented as the sequential composition of the angelic and demonic updates. Together with the standard strong negation , we set up the duality between the angel and demon. The fuzzy predicate transformers semantics of contract statements is established and a simple example of contract statements is given.展开更多

To im-prove the interoperability of services for SAAS, it is crucial to build requirements semantics that will cross the entire lifecycle of services especially on requirements stage. In this paper, a requirements semantics interoperability extend-ing approach called Connecting Ontologies (CO) that will act as semantics information carrier designing to facilitate the requirements identification and services composition is proposed. Semantic measurement of Chinese scenario is explored. By adopting the approach, a series of tools support for transport domain are developed and applied based on CO and DPO (Domain Problem Ontology) to enforce requirements engineering of networked software efficiently.展开更多
