Abstract [en]

Establishing buyer awareness contains two major business processes: (1) sellers advertise their products and (2) buyers become aware of them or first learn of them. On the Internet, e-mail is the major means by using messaging for realizing buyer awareness, but critical challenges are ahead from the perspectives of legitimacy and efficiency. This paper provides an infrastructure for establishing buyer awareness, called SAMI (Specification, Agreement, and Matchmaking Infrastructure), enabling all  sellers' advertisements to formally reach potential buyers instead of being unread. Under the SAMI, sellers and buyers need to adjust to each other: (1) buyers should launch their Web services to recieve sellers' advertisements and install their own agents to process all of them and (2) sellers should specify their products simply but with rich semantics that the agents can process instead of using natural language which is relatively hard to process. Three contributions are included. First, the concept of personal ontology is defined for sellers and buyers to add rich semantics into their keywords for semantic matchmaking. Second, an ontology as well as an  XML Schema is designed for encoding messages for simplifying for agreement of messaging. Third, an algorithm is provided to match buyers' keywords (requirements) with sellers' keywords (advertisments) with regard to synonym, polysemy and partial matching. In particular all keywords can be any classes or instances from different ontologies. A prototype system has been implemented and tested

Abstract [en]

Fierce competitions and pursuits of excellence require all applications, internal or external, to be integrated for business-to-business communications. Standards play an important role in fulfilling the requirement. This dissertation focuses on Business-to-Business standards or XML-based frameworks for Internet commerce

First, we analyze what the standards are and how they interact. Fifteen influential standards are selected: eCo Framework, ebXML, UBL, UDDI, SOAP, WSDL, RosettaNet, Open Applications Group, VoiceXML, cXML, Wf-XML, OFX, ICE, RDF, and OWL. Basically each standard has to provide transport mechanisms and message structures for general and/or specific applications. In terms of message structure definition, they can be classified as two types: syntax-based, for defining messages syntactically and semantics-based, like RDF and OWL for defining messages semantically.

Second, for transiting from syntax to semantics, we provide a reuse-based method to develop the ontology by reusing existing XML-based standards. This is a kind of knowledge reuse, for instance, using previously developed structures, naming conventions and relationships between concepts.

Third, we exploit how to use these standards. We propose an approach that combines RDF and OWL with SOAP for building semantic Web services. Three levels of combinations are provided: Simple Reference, Direct Embedment, and Semantic SOAP.

Fourth, we design an infrastructure aimed at creating a formal channel by using Web services and semantic Web for establishing buyer awareness, i.e., buyers first become aware of products/promotions offered by sellers. We propose the concept of personal ontology, emphasizing that ontology is not only a common and shared conceptualization but also can be used to specify personal views of the products by sellers and buyers. The agreements between buyers and sellers can be described in XML schema or ontology in OWL. A semantic matchmaking algorithm is designed and implemented considering synonym, polysemy and partial matching.
