The shift toward global networking brings with it many opportunities and challenges. In this paper, we discuss key technologies in achieving global semantic interoperability among heterogeneous information systems, including both traditional and Web data sources. In particular, we focus on the importance of this capability and the technologies we have designed to overcome ontological heterogeneity, a common type of disparity in financial information systems. Our approach to representing and reasoning with ontological heterogeneities in data sources is an extension of the context interchange (COIN) framework, a mediator-based approach for achieving semantic interoperability among heterogeneous sources and receivers. We also analyze the issue of ontological heterogeneity in the context of source-selection, and offer a declarative solution that combines symbolic solvers and mixed integer programming techniques in a constraint logic-programming framework. Finally, we discuss how these techniques can be coupled with emerging Semantic Web related technologies and standards such as Web-Services, DAML+OIL, and RuleML, to offer scalable solutions for global semantic interoperability.

While there are efforts to establish a single intemational accounting standard, there are strong current and future needs to handle heterogeneous accounting methods and systems. We advocate a context-based approach to dealing with multiple accounting standards and equational ontological conflicts. In this paper we first define what we mean by equational ontological conflicts and then describe a new approach, using Consmint Logic Programming and abductive reasoning, to reconcile such conflicts among disparate information systems. In particular, we focus on the use of Consmint Handling Rules as a simultaneous symbolic equation solver, which is a powerful way to combine, invert and simplify multiple conversion functions that translate between different contexts. Finally, we demonstrate a sample application using our prototype implementation that demonstrates the viability of our approach.

The COntext INterchange Strategy (COIN) is an approach to solving the problem of interoperability of semantically heterogeneous data sources through context mediation. The existing implementation of COIN uses its own notation and syntax for representing ontologies. More recently, the OWL Web Ontology Language is becoming established as the W3C recommended ontology language. A bridge is needed between these two areas and an explanation on how each of the two approaches can learn from each other. We propose the use of the COIN strategy to solve context disparity and ontology interoperability problems in the emerging Semantic Web both at the ontology level and at the data level. In this work we showcase how the problems that arise from context-dependant representation of facts can be mitigated by Semantic Web techniques, as tools of the conceptual framework developed over 15 years of COIN research. 1.

Data about products and services is of paramount importance in most inter-organizational business processes. For business-to-business (B2B) scenarios, a great number of XML-based message specifications are available, which cover various processes and types of transactions. These specifications support the respective data exchange tasks by providing a common representation for products and services in the form of syntactical conventions with some light-weight formal semantics. However, an analysis of the underlying models shows that technical product data and commercial product data are being represented in a fundamentally different manner. In particular show the commercial models both a higher syntactical complexity and more semantic heterogeneity. In this paper, we propose to align the representation of technical and commercial views on product data in message specifications. Our approach is based on the PLIB ontology, which was originally described in ISO 13584. We have evaluated our proposal by applying it to an industrial message specification for electronic catalogs, and can show that the novel approach reduces representational mismatches in B2B processes and simplifies systems integration in such scenarios.

Abstract. This paper examines the opportunities and challenges related to data and process integration architectures in the context of Web Services. A primary goal of most enterprises in today’s economic environment is to improve productivity by streamlining and aggregating business processes. This paper illustrates how integration architectures based on Web Services offer new opportunities to improve productivity that are expedient and economical. First, the paper introduces the technical standards associated with Web Services and provides business example for illustration. Abstracting from this example, we introduce a concept we call Process Aggregation that incorporates data aggregation and workflow to improve productivity. We show that Web Services will have a major impact on Process Aggregation, making it both faster and less expensive to implement. Finally, we suggest some research directions relating to the Process Aggregation challenges facing Web Services that are not currently being addressed by standards bodies or software vendors. These include context mediation, trusted intermediaries, quality and source selection, licensing and payment mechanisms, and systems development tools. 1

Abstract—The National Research Council has noted that "[A]lthough there are many private and public databases that contain information potentially relevant to counterterrorism programs, they lack the necessary context definitions (i.e., metadata) and access tools to enable interoperation with other databases and the extraction of meaningful and timely information. " In this paper we present examples of these problems and a technology developed at MIT, called context mediation, which provides

We present a simple application of semantic integration using the RDF model of metadata, namely, the construction and maintenance of a yearbook. It can be built and used by organizations which already have their information on the Web and require to keep yearbooks to service advanced searching facilities. Unlike traditional approaches, ours ensures wide interoperability, extensibility and historical recording by using RDF and a decentralized approach.
