XDM enables the transformation by externalizing the specification of the mapping in a script and using an efficient run-time engine that automates the conversion task. The runtime engine is independent from the mapping script. A parser converts a mapping script into an internal conversion object. For the mapping from relational to XML, we use a tagging tree as a conversion object inside the runtime engine, and use an SQL outer-join scheme to combine multiple SQL queries in order to reduce the number of backend relational database accesses. For the mapping from XML to relational, the conversion object is a shredding tree, and we use an innovative algorithm to process the XML as a stream in order to achieve linear complexity with respect to the size of the XML document.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

By taking advantage of the redundancy inherent in the Web, each answer found by the system is triangulated (confirmed or disconfirmed) against other possible answers. Our approach is entirely self-learning: it does not involve any linguistic resources, nor it does require any manual tuning.

These proposals range from runtime API-based interfaces to XML-based programming languages. The subject of this paper is XJ, a research language that proposes novel mechanisms for the integration of XML as a first-class construct into JavaTM. The design goals of XJ distinguish it from pastwork on integrating XML support into programming languages ---specifically, the XJ design adheres to the XML Schema and XPathstandards, and supports in-place updates of XML data thereby keeping with the imperative nature of Java. We have also built a prototype compiler for XJ, and our preliminary experimental results demonstrate that the performance of XJ programs can approach that of tradition allow level API-based interfaces, while providing a higher level of abstraction.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

This paper deals with the intersection of two of these areas: process modeling as it pertains to automated contracting. Specifically, we propose a logic, called CTR-S,which captures the dynamic aspects of contracting for services.Since CTR-S is an extension of the classical first-order logic, it is well-suited to model the static aspects of contracting as well. A distinctive feature of contracting is that it involves two or more parties in a potentially adversarial situation. CTR-S is designed to model this adversarial situation through its novel model theory, which incorporates certain game-theoretic concepts. In addition to the model theory, we develop a proof theory for CTR-S and demonstrate the use of the logic formodeling and reasoning about Web service contracts.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

So, there is a need for serving implementation of these standards from a single, central store to ease the use and management of the implementations. This paper presents EIOP, an E-commerce Interoperability Platform. EIOP is designed to provide a central store for implementations of e-commerce specifications to be able to use and configure these implementations from a single, central point.

It is highly likely that several records on the web whose textual representations differ may represent the same real world entity. These records are called approximate duplicates. Data integration seeks to identify such approximate duplicates and merge them into integrated records. Many existing data integration algorithms make use of approximate string join, which seeks to (approximately) find all pairs of strings whose distances are less than a certain threshold. In this paper, we propose a new mapping method to detect pairs of strings with similarity above a certain threshold. In our method, each string is first mapped to a point in a high dimensional grid space, then pairs of points whose distances are 1 are identified. We implement it using Oracle SQL and PL/SQL. Finally, we evaluate this method using real data sets. Experimental results suggest that our method is both accurate and efficient.","PeriodicalId":409891,"journal":{"name":"WWW Alt.
