Item An Integration Technology for Long Distance Logistics and Supply Chain Management(2009-04-05) Cho, Hyunbo; Woo, Jungyu; Ivezik, Nenad; Jones, Albert; Denno, Peter; Peng, YunDespite the global economic downturn, import/export trade will continue to grow. That trade depends on many intercontinental, long-distance, logistics partners. Those partners include exporters, brokers, truckers, customs, carriers, and importers who depend on information to do their jobs. The software support systems that generate, use, and exchange that information are exceedingly complex and highly heterogeneous in nature. Inadequate approaches to integration of such systems means that trading partners encounter recurring problems including late deliveries, inaccurate tracking, insufficient visibility, poor security, unreliable planning, and unnecessary disruptions. In this paper, we propose an integration approach that will reduce or eliminate these problems. That approach must (1) ensure interoperability among logistics applications; (2) provide shipment visibility to all trading partners; (3) reduce the average and variance of transport times; (4) accommodate associated international standards; (5) reuse legacy applications, where possible; and, (6) facilitate recovery from supply chain disruptions. Our approach has four proposals. First, we propose a collaboration architecture and a federated network framework using SOA-based concepts. Second, we propose a standards-based approach to message specification that will facilitate interoperability among trading partners. Third, we propose a framework for fast recovery from supply chain disruptions. Fourth, we propose the concept of a test bed to verify that proposed commercial solutions conform to those standards.. We believe that our approach will impact the intercontinental logistics industry significantly ā in terms of quantitative and qualitative measures. First, it will increase shipment visibility dramatically among global trading partners. Second, it will decrease both the average and variance of transport times significantly. Third, it will reduce the cost associated with premium freight, and improve data quality and integrity.Item A Layered Approach to Semantic Similarity Analysis of XML Schemas(IEEE, 2008-08-05) Kim, Jaewook; Peng, Yun; Kulvatunyou, Serm; Ivezic, Nenad; Jones, AlbertOne of the most critical steps to integrating heterogeneous e-Business applications using different XML schemas is schema mapping, which is known to be costly and error-prone. Past research on schema mapping has not fully utilized semantic information in the XML schemas. In this paper, we propose a semantic similarity analysis approach to facilitate XML schema mapping, merging and reuse. Several key innovations are introduced to better utilize available semantic information. These innovations, including: 1) a layered semantic structure of XML schema, 2) layered specific similarity measures using an information content based approach, and 3) a scheme for integrating similarities at all layers. Experimental results using two different schemas from an real world application demonstrate that the proposed approach is valuable for addressing difficulties in XML schema mapping.Item A Probabilistic Framework for Semantic Similarity and Ontology Mapping(Institute of Industrial Engineers, 2007-05-19) Peng, Yun; Ding, Zhongli; Pan, Rong; Yu, Yang; Kulvatunyou, Boonserm; Ivezik, Nenad; Jones, Albert; Cho, HyunboWe propose a probabilistic framework to address uncertainty in ontology-based semantic integration and interopera- tion. This framework consists of three main components: 1) BayesOWL that translates an OWL ontology to a Bayesian network, 2) SLBN (Semantically Linked Bayesian Networks) that support reasoning across translated BNs, and 3) a Learner that learns from the web the probabilities needed by the other modules. This framework expands the semantic web and can serve as a theoretical basis for solving real world semantic integration problems.Item Semantic Resolution for E-commerce(ACM, 2002-07-15) Peng, Yun; Zou, Youyong; Luan, Xiaocheng; Ivezic, Nenad; Gruninger, Michael; Jones, AlbertWe describe a research project on resolving semantic differences for multi-agent systems (MAS) in electronic commerce. The approach can be characterized as follows: (1) agents in a MAS may have their own specific ontologies defined on top of a shared base ontology; (2) concepts in these ontologies are represented as frame-like structures based on DAML+OIL language; (3) the semantic differences between agents are resolved at runtime through inter-agent communication; and (4) the resolution is viewed as an abductive inference process, and thus necessarily involves approximate reasoning.
