Abstract
Today’s information technologies, such as autonomic computing, offer companies new ways to do businesses. Those that fail to embrace and use such advantages in the next years are in danger to disappear or become zombie ones. In contrast, those pioneering these next-generation technology-business strategies will gain strategic advantage. This paper is about AWS-Net Traveler, which is an Autonomic Web Services Framework for purposes to perform Business Processes in an Autonomous mode. The main feature of this proposal is a decentralized architecture that heavily relies on Peer-to-Peer Web Service Brokers to coordinate, plan and perform Web Service choreographies. We include several use cases scenarios and how to address them using the proposed framework. Also, here is discussed the business model for Autonomic Business Processes model based on Autonomic Choreography of Web Services. Finally, we introduce the Architecture of AWS-Net Traveler and the description of their main components.

Abstract
Web services are becoming the ultimate response for organizations and companies offering their core business services over the Internet. In fact, those business services are being offered through Web services which act like APIs providing the logic to handle a business service. Although, some Web services do not require other Web services to accomplish their tasks, the most interesting ones do the opposite. In that sense, Web services are orchestrated to create new complex business services that can reach Web services of several companies. For the purpose to handle it we proposed Net Traveler that is an autonomic Framework for collaboration, orchestration and choreography of Web services. Some design requirements are critical in the composition of Web services. Reliability and scalability among others must be done in order to offer a minimum of quality of service for composite Web services. In this paper we present the architecture of FT-Net Traveler which provides reliability through fault tolerance and scalability through load balancing to composite Web services without requiring modifications on them.

 
Net Traveler: A Framework for Autonomic Web Services Collaboration, Orchestration and Choreography in E-Government Information Systems

Abstract
Next-generation Government Information Systems will integrate large amounts of heterogeneous data sources located on distributed networks like the Internet. We present Net Traveler which is a framework for web services collaboration, orchestration and choreography in peer-to-peer autonomic environments. The main feature of our new approach is the elimination of a central coordination site running the queries and the autonomic query execution. Moreover, control information is embedded with the request for data, and also with the partial results in an XML document...

InfoRadar-cl: A Cross-Lingual Information Discovery Tool exploiting Automatic Document Categorization
Jairo E. Valiente and Bienvenido Velez
Proceedings of the IASTED International Conference Information and Knowledge Sharing, November 2002.
Full text available pdf 474 KB


Abstract
Today we face a fundamental problem in information retrieval. Multilingual information resources are becoming accessible throughout the world at an unprecedented rate. Although research has demonstrated that new algorithms and user interfaces are desirable to deal with the particularities of multilingual corpora, we are beginning to see effective results. Starting from our previous work on Inforadar, this paper describes the design of Inforadar-cl, a prototype search system supporting the anticipatory user interface supported by Inforadar, but redesigned to support multilingual queries and results...

 
Interactive Query Hierarchy Generation Algorithms for Search Result Visualization
Bienvenido Velez and Jairo E. Valiente
Proceedings of the IASTED International Conference Internet and Multimedia Systems and Applications, August 2001.
Full text available pdf 203 KB


Abstract
This paper presents an anticipatory user interface for search result visualization that exploits Query Lookahead, a technique that eagerly evaluates refined queries automatically generated from an initial user query. A selected collection of refined queries is displayed to the user as an Interactive Query Hierarchy. Each child query refines its parent with additional indexing terms that are extracted from the documents that match the parent query. The user interface presents the results of each selected child query in advance. Interactive query hierarchies can also break down a large and imprecise result set in categories determined by the indexing terms appearing in the documents in the result set...
