تسمح منهجيات هندسة الوب Web Engineering بتمثيل خدمات الوب العادية و نمذجتها ضمن دورة الحياة البرمجية لتطوير تطبيقات الوب Web Development ضمن ما يسمى البنى الموجهة بالخدمات (Service Oriented Architecture (SOA, و لكن تتفاوت هذه المنهجيات في طريقة دعمها و حجمها لتمثيل مكونات الوب الدلالي و خصوصاً مكونات خدمات الوب الدلالي (Semantic Web Services (SWS وفق أطر العمل المختلفة. يقدم هذا البحث مقارنة بين منهجيات هندسة الوب المختلفة بشكل عام مع التركيز على طريقة دعمها لتمثيل مكونات الوب الدلالي و خدمات الوب العادية. و نبين هنا قصور هذه المنهجيات في نمذجة خدمات الوب الدلالي، ثم نقدم توسعة لمنهجية معروفة WebML و إضافة مخططات إضافية لنمذجة خدمات الوب الدلالي وفق الإطار DAML-S و بناء أداة برمجية لتوليد هذه الخدمات آلياً اعتماداً على هذه المخططات و إجراء عملية المطابقة بين الإعلان و الطلب عن خدمة و ترتيب نتائج المطابقة الدلالية Semantic Ranking.
Web Engineering Methodologies (WebML UWE Hera RMM) support the representation and modeling of web services in a lifecycle, based on service oriented architecture (SOA). Theses methodologies, however, vary in supporting semantic web components and semantic web services (SWS). In this work, we present a general comparison between different web engineering methodologies with special attention to semantic web components modeling and we track the weaknesses of common web engineering methodologies in modeling semantic web services. This work presents also an extension to WebML methodology where symbols, diagrams and notions are added to support the modeling of semantic web services according to DAML-S framework (DARPA agent markup language for services). Additionally, a software tool was built to support this extension and generate ontologies of semantic web services automatically based on new diagrams. This tool also supports matching with semantic ranking between semantic web services advertisements and client's requests.

This study will put spot light on web applications testing methods
and tools from the security aspects, and we will explain the details
about using these tools, after we have explained the most famous
weak points and vulnerabilities that web appli
cations suffer from.
At the end we will evaluate these tools.
By this study we try to help developers to choose the most
suitable method and tool for their needs.
With the increasing growth in popularity of Web services and SOA, discovering
relevant Web services becomes a significant challenge. The introduction of intentional
services is necessary to bridge the gap between low level, technical software-servi
ce
descriptions and high level, strategic expressions of business needs for services.
Current Web Services technology based on UDDI and WSDL does not make use of
this “intention” and therefore fails to address the problem of matching between capabilities
of services and business user needs.
This work addresses the problem of intentional semantic web service search in
Arabic, where a novel approach is proposed for partitioning user goals based on Arabic
verb ontology, in addition to showing a practical example about the effect of applying verb
ontology in intentional web service search.
The company structure is a method based on the modeling for
analysis; planning, design, and management the information
technique to promote process in order to take the right decision.
Thus, the structure of the company's models must include
info
rmation for each company in order to achieve cooperation
between them and the exchange of information among its services,
so the company structure need the support from several models, but
the establishment of such models is expensive and without a fixed
value. It is advisable to find models that support actually what to
achieve, especially with the development of modern technology that
pay the companies increasingly towards Web services exchange.
To overcome these problems, we present a model based on serviceoriented,
which allows the exchange of information and assembly
services provided by different companies in a dynamic way taking
into account the context of cooperation, and organize a coordinated
and coherent services chain, thus provides a way to exchange
information and interaction of commercial services between
companies.
We aimed to distinguish between them and the other research areas such as information retrieval and data mining. we tried to determine the general structure of such systems which form a part of larger systems that have a mission to answer user querie
s based on the extracted information. we reviewed the different types of these systems, used techniques with them and tried to define the current and future challenges and the consequent research problems.
Finally we tried to discuss the details of the various
implementations of these systems by explaining two platforms Gate and OpenCalais and comparing between their information
extraction systems and discuss the results.
Semantic Web is a new revolution in the world of the Web, where information and
data become viable for logical processing by computer programs. Where they are
transformed into meaningful data network. Although Semantic Web is considered the
future
of World Wide Web, the Arabic research and studies are still relatively rare in this
field. Therefore, this paper gives a reference study of Semantic Web and the different
methods to explore the knowledge and discover useful information from the vast amount
of data provided by the web. It gives a programming example like application of some of
these techniques provided by the Semantic Web and methods to discover the knowledge of
it. This simplified programming example provides services related to higher education
Syrian government, such as information about the Syrian public universities like the name
of the university (Syrian Virtual University, Tishreen, Aleppo, Damascus, and Al Baath),
address of the university, its web site, number of students and a summary of the university,
which helps intelligent agents to find those services dynamically.
