This document presents a proposed solution for developing semantic web services using UML and Acceleo. It discusses challenges with current semantic web service development including steep learning curves and lack of standardized tools. The proposed solution uses UML models to generate syntactic service descriptions and Acceleo templates to derive semantic descriptions from UML models and ontologies. A use case scenario and demonstration are presented, followed by a discussion of related work and conclusions on the need for simpler and more efficient semantic web service development tools.
The document proposes a model-driven engineering method to systematically derive user interfaces for a workflow information system from a series of models. The method decomposes a workflow according to the Cameleon Reference Framework and UsiXML task model. It presents a conceptual model for a workflow information system and describes how the interfaces are designed from task and domain models through to concrete, final user interfaces. The method has been validated through several case studies and partially supported by a software tool.

Composite Design Pattern For Feature- Oriented Service Injection And Composit...dannyijwest
With the advent of newly introduced programming models like Feature-Oriented Programming (FOP), we
feel that it will be more flexible to include the new service invocation function into the service providing
server as a Feature Module for the self-adaptive distributed systems. A composite design patterns shows a
synergy that makes the composition more than just the sum of its parts which leads to ready-made software
architectures. In this paper we describe the amalgamation of Visitor and Case-Based Reasoning Design
Patterns to the development of the Service Invocation and Web Services Composition through SOA with the
help of JWS technologies and FOP. As far as we know, there are no studies on composition of design
patterns for self adaptive distributed computing domain. We have provided with the sample code developed
for the application and simple UML class diagram is used to describe the architecture
COMPOSITE DESIGN PATTERN FOR FEATUREORIENTED SERVICE INJECTION AND COMPOSITIO...dannyijwest
This document proposes a composite design pattern for feature-oriented service injection and composition of web services in distributed computing systems with service-oriented architecture (SOA). The pattern combines the visitor and case-based reasoning patterns. It allows new services to be included as feature modules at runtime. When a complex service is requested, the case-based reasoning pattern selects the best matching web service description language (WSDL) based on input parameters. If a single server cannot fulfill the request, the visitor pattern is used to invoke services on other servers to compose the response. The pattern provides capabilities for web service composition, invocation and flexible inclusion of new services.

Model-Driven Development of Web Applicationsidescitation
Over the last few years Model-Driven Development (MDD) has been regarded as
the future of Software Engineering, offering architects the possibility of creating artifacts to
illustrate the design of the software solutions, contributing directly to the implementation of
the product after performing a series of model transformations on them. The model-to-text
transformations are the most important operations from the point of view of the automatic
code generation. The automatic generation or the fast prototyping of applications implies an
acceleration of the development process and a reduction of time and effort, which could
materialize in a noticeable cost reduction. This paper proposes a practical approach for the
model-based development of web applications, offering a solution for the layered and
platform independent modeling of web applications, as well as for the automatic generation
of software solutions realized using the ASP.NET technology.

It also covers configuration management and testing considerations for SOA projects.
Recent developments on the Web are marked by the growing support for the Linked Data initiative, which encourages government and public organisations, as well as private institutions, to expose their data on the Web. This results in a plentitude of multi-lingual document collections where the original resources are published in the language, in which they are available. The challenges of multilingualism present on the Semantic Web are also reflected in the context of services on the Web, characterised by the rapid increase in popularity and use of Web APIs, as indicated by the growing number of available APIs and the applications built on top of them. Web APIs are commonly described in plain-text as part of Web pages, following no particular guidelines and conforming to no standards, despite some initial approaches in the area. Therefore, API providers publish descriptions in any language they see fit, making the service discovery and the subsequent processing of the documentation challenging tasks. We present a cross-lingual approach that calculates semantic similarity of text to help classify and annotateWeb APIs, based on their textual descriptions. Furthermore, we show how our solution can be implemented as part of SWEET, which is a tool that enables the semi-automated creation of semantic Web API descriptions. In addition, we demonstrate how the cross-lingual approach can be adopted to support the language-independent discovery of Web APIs.
The document describes the need for and objectives of developing a paperless SQL-based examination system. Currently, paperless exam systems mainly focus on objective questions and cannot adequately evaluate subjective questions involving SQL programming. The proposed system aims to analyze SQL queries and programming questions in real-time to provide prompt feedback to students. It will use a dynamic algorithm to interpret queries and compare student responses to standard outputs. The system will be developed using J2EE and follow the MVC pattern, with a practice test facility and functions for query analysis, reporting, and administration. Its goals are to reduce grading workload, promote learning, and comprehensively evaluate students' SQL skills.

1. Exploiting UML and Acceleo for
Developing Semantic Web Services
Jabu. Mtsweni

3. 1. INTRODUCTION
• Semantic Web Services (SWS) = Web Services (WS) +
Semantic Web (SW)
• Ontologies (formal representation of knowledge) plays a key
role in SWS.
• SWS promise a number of benefits:
• Improved representation, sharing, searching,
reasoning, and re-use of data and services on the Web
• Automation of various tasks on the Web, such as service
discovery, selection, execution, and monitoring
4. 2.1 BACKGROUND
SWS rely on semantic descriptions for automation
Semantic descriptions describe non-functional and
functional (capability and behaviour) aspects of
services
Semantic descriptions are normally derived from
ontologies
Models such as WSMO, OWL-S based on ontology
languages (e.g. WSML and OWL) are available
Other light-weight approaches, such as WSMO-Lite
and SAWSDL are also available to define ontologies
and descriptions
5. 2.2 BACKGROUND (CHALLENGES)
Steep learning curve of emerging semantic models
Complex textual semantic description languages
Current tools are tightly-coupled to specific
languages
Lack of support for the development of semantic
services
Lack of unified semantic service development tools
Lack of Standardization (e.g. no common standard
for defining semantic descriptions)
6. 3. PROPOSED SOLUTION
• The development process of semantic services
comprises a number of tasks
• service implementation
• syntactic descriptions
• semantic descriptions
• Deployment
• Publication
• Without the necessary tools to support these tasks
the development process of semantic services
could be prolonged
11. 5. RELATED WORK
• There are a number of solutions that have been proposed to
date for facilitating the development of semantic services.
• OWL-S IDE [by Srinivasan, Paolucci, and Sycara ]
• Translates Java code into WSDL
• WSDL to skeletal OWL-S ontologies
• Only Supports OWL-S
• Generation of Semantic descriptions lacks details
needed for automation
• Reverse Engineering [by Bensaber and Malki]
• Follows model-driven approach
• WSDL translated to UML class and activity diagrams
• Diagrams then converted to OWL-S descriptions
• Relies heavily on syntactic descriptions
12. 6. CONCLUSION
Semantic services are seen as the main building block for the
Next Generation of the Web
The driving philosophy behind WS & SWS development is
programmer’s productivity.
Simpler and Efficient tools are then necessary for a facilitating
the implementation of semantic technologies
The proposed approach is viewed as one possible solution in
dealing with the complexities and restrictions involved in
implementing semantic services
Further research points to improving the suggested approach
by incorporating software agents; which are relevant for
processing the semantic descriptions in an autonomous,
proactive, and reactive manner on Web
Thus, in this paper we propose the approach presented in the Figure as one possible solution for facilitating the process of building semantic services by exploiting existing and matured technologies. Creation of service models representing the structure and behavior of targeted semantic services and domain knowledge. For this purpose, UML tools embedded within Eclipse can be used to design class diagrams and activity diagrams. The designed service models could also be annotated using pre-defined keywords or a generic UML profile that comprises stereotypes and tagged values for different semantic description languages, such as WSMO or OWL-S. In this manner, a single model could be used to generate semantic descriptions based on different languages. (2) After compatible models have been designed using the UML2 SDK for Eclipse or even imported from external sources and annotated; automatic model transformations using Acceleo transformation scripts compatible with the Eclipse environment could follow. Acceleo transformation rules that were implemented for the proposed solution.
Table shows a snippet of an Acceleo script developed for transforming annotated UML class diagrams into WSMO domain ontologies. As it can be noted in Line 8, the script would only generate WSMO-compliant ontologies if the class diagram is annotated with the WSMO keyword. The Acceleo transformation script could also be easily edited to support new requirements (e.g. new semantic description language).
In this section, the value of the proposed approach is demonstrated through a use-case scenario adapted from a Sixth EU Framework Programme project called DIP [29]. The scenario is based on developing semantic services for a Mortgage Comparator Web application. The application is intended to compare mortgage loans offered by different financial institutions for a specific property that an ordinary individual would like to buy. Based on the first step of the suggested solution in the previous slides, an abstract service model in the Figure was designed using the UML2 SDK for Eclipse, and subsequently utilized by the Acceleo transformation scripts for automatically generating all the appropriate skeletons and code stubs. The <<RESTful>> and <<WSMO>> UML stereotypes were exploited to annotate the service model in order to aid the model transformers to automatically generate RESTful services and WSMO descriptions as planned.
This slides demonstrates the Java code, and the partial WSMO domain ontologies generated through the model2semantics transformation script. Only the domain and service ontologies of classes annotated with the keyword <<WSMO>> are generated in this case. The process of generating OWL-S compliant descriptions would only require an annotation of service models with the <<OWL-S>> keywords. Other languages can easily be accommodated by defining additional mappings and transformation rules. These could be integrated within the Eclipse environment without disrupting any previously defined transformation rules.
