Adjusting WSMO API Reference Implementation to Support More Reliable Entity Persistence

Title: Adjusting WSMO API Reference Implementation to Support More Reliable Entity Persistence<br/><br/>Authors: Marinchev, Ivo<br/><br/>Abstract: In the presented paper we scrutinize the persistence facilities provided by the WSMO API referenceimplementation. It is shown that its current file data-store persistence is not very reliable by design. Our ultimategoal is to explore the possibilities of extending the current persistence implementation (as an easy short-runsolution) and implementing a different persistent package from scratch (possible long-run solution) that is morereliable and useful. In order to avoid “reinventing the wheel“, we decided to use relational database managementsystem to store WSMO API internal object model. It is shown later that the first task can be easily achievedalthough in not very elegant way, but we think that the later one requires some changes in the WSMO API tosmooth out some inconsistencies in the WSMO API specification in respect to other widely used Javatechnologies and frameworks.<br/><br/>Description: * The research has been partially supported by INFRAWEBS - IST FP62003/IST/2.3.2.3 Research Project No.511723 and “Technologies of the Information Society for Knowledge Processing and Management” - IIT-BASResearch Project No. 010061.INFRAWEBS BPEL-Based Editor for Creating the Semantic Web Services Description

Title: INFRAWEBS BPEL-Based Editor for Creating the Semantic Web Services Description<br/><br/>Authors: Atanasova, Tatiana<br/><br/>Abstract: INFRAWEBS project [INFRAWEBS] considers usage of semantics for the complete lifecycle ofSemantic Web processes, which represent complex interactions between Semantic Web Services. One of themain initiatives in the Semantic Web is WSMO framework, aiming at describing the various aspects related toSemantic Web Services in order to enable the automation of Web Service discovery, composition, interoperationand invocation. In the paper the conceptual architecture for BPEL-based INFRAWEBS editor is proposed that isintended to construct a part of WSMO descriptions of the Semantic Web Services. The semantic description ofWeb Services has to cover Data, Functional, Execution and QoS semantics. The representation of Functionalsemantics can be achieved by adding the service functionality to the process description. The architecture relieson a functional (operational) semantics of the Business Process Execution Language for Web Services(BPEL4WS) and uses abstract state machine (ASM) paradigm. This allows describing the dynamic properties ofthe process descriptions in terms of partially ordered transition rules and transforming them to WSMO framework.Semantic Description of Web Services and Possibilities of BPEL4WS

Title: Semantic Description of Web Services and Possibilities of BPEL4WS<br/><br/>Authors: Grigorova, Vladislava<br/><br/>Abstract: The using of the upsurge of semantics web technologies gives a possibility for an increasing of theflexibility, extensibility and consistency of the existent industrial standards for modeling of web services. In thepaper the types of semantic description of web services and the degree of their realization in BPEL4WS(Business Process Execution Language for Web Services) respectively on the abstract and executable level aretreated. The methods for using of BPEL4WS for the purposes of semantic web services in the direction of theirsemi-automatic integration are suggested.A Survey on the Integration of Enterprise Applications as a Service

Title: INFRAWEBS Axiom Editor – A Graphical Ontology-Driven Tool for Creating Complex Logical Expressions<br/><br/>Authors: Agre, Gennady; Kormushev, Petar; Dilov, Ivan<br/><br/>Abstract: The current INFRAWEBS European research project aims at developing ICT framework enablingsoftware and service providers to generate and establish open and extensible development platforms for WebService applications. One of the concrete project objectives is developing a full-life-cycle software toolset forcreating and maintaining Semantic Web Services (SWSs) supporting specific applications based on Web ServiceModelling Ontology (WSMO) framework. According to WSMO, functional and behavioural descriptions of a SWSmay be represented by means of complex logical expressions (axioms). The paper describes a specialized userfriendlytool for constructing and editing such axioms – INFRAWEBS Axiom Editor. After discussing the maindesign principles of the Editor, its functional architecture is briefly presented. The tool is implemented in EclipseGraphical Environment Framework and Eclipse Rich Client Platform.INFRAWEBS Semantic Web Service Development on the Base of Knowledge Management Layer

Title: INFRAWEBS Semantic Web Service Development on the Base of Knowledge Management Layer<br/><br/>Authors: Nern, Joachim; Agre, Gennady; Atanasova, Tatiana; Marinova, Zlatina; Micsik, András; Kovács, László; Saarela, Janne; Westkaemper, Timo<br/><br/>Abstract: The paper gives an overview about the ongoing FP6-IST INFRAWEBS project and describes the mainlayers and software components embedded in an application oriented realisation framework. An important part ofINFRAWEBS is a Semantic Web Unit (SWU) – a collaboration platform and interoperable middleware forontology-based handling and maintaining of SWS. The framework provides knowledge about a specific domainand relies on ontologies to structure and exchange this knowledge to semantic service development modules.INFRAWEBS Designer and Composer are sub-modules of SWU responsible for creating Semantic Web Servicesusing Case-Based Reasoning approach. The Service Access Middleware (SAM) is responsible for building up thecommunication channels between users and various other modules. It serves as a generic middleware fordeployment of Semantic Web Services. This software toolset provides a development framework for creating andmaintaining the full-life-cycle of Semantic Web Services with specific application support.FP6-ist INFRAWEBS European Research Project

Title: Generalization by Computation Through Memory<br/><br/>Authors: Gopych, Petro<br/><br/>Abstract: Usually, generalization is considered as a function of learning from a set of examples. In present workon the basis of recent neural network assembly memory model (NNAMM), a biologically plausible 'grandmother'model for vision, where each separate memory unit itself can generalize, has been proposed. For such ageneralization by computation through memory, analytical formulae and numerical procedure are found tocalculate exactly the perfectly learned memory unit's generalization ability. The model's memory has complexhierarchical structure, can be learned from one example by a one-step process, and may be considered as asemi-representational one. A simple binary neural network for bell-shaped tuning is described.Neural Network Based Approach for Developing the Enterprise Strategy

Title: Neural Network Based Approach for Developing the Enterprise Strategy<br/><br/>Authors: Kovacheva, Todorka; Toshkova, Daniela<br/><br/>Abstract: Modern enterprises work in highly dynamic environment. Thus, the developing of company strategy isof crucial importance. It determines the surviving of the enterprise and its evolution. Adapting the desiredmanagement goal in accordance with the environment changes is a complex problem. In the present paper, anapproach for solving this problem is suggested. It is based on predictive control philosophy. The enterprise ismodelled as a cybernetic system and the future plant response is predicted by a neural network model. Thepredictions are passed to an optimization routine, which attempts to minimize the quadratic performance criterion.Using ORG-Master for Knowledge Based Organizational Change
