Opportunities continue to grow for science students to search the web for mathematical terms used in engineering lectures. However, it is not easy to obtain sets of web documents that are unified and closely related to each other. In this paper, we propose a system that obtains suitable sets of web pages. First, we adopt a syllabus that represents a lecture and use it as input data. then our system presents sets of mathematical web pages related to the input syllabus. the system also includes a mathematical dictionary, languageprocessing algorithms, stop lists, and ranking algorithms. We describe how it searches for useful sets of web pages and presents them to users. We also show the results of two experiments. the first determined the most suitable values of the system's parameters. In the second, engineering graduate students evaluated the relevance among five syllabi and the presented web pages.
We demonstrate our large-scale webinformation analysis system called WISDOM2013, which consists of several deep semantic analysis systems such as a factoid QA, a non-factoid QA and a sentiment analyzer, and a softwar...

the vision of semantic web is to have a web of things instead of web of documents in a form that can be processed by machines. this vision could be achieved on the existing web using semantic annotation based on common and public ontologies. Due to exponential growth and huge size of the web sources, there is a need to have fast and automatic semantic annotation services of web documents. Since Arabic language received less attention in semantic web research as compared to Latin languages especially in the field of semantic annotation. this motivates us in this paper to present semantic web services that support the semantic annotation of Arabic language documents. the services accept documents and ontologies and produce annotations of these documents using different output formats. the proposed services could be used for building semantic web applications and semantic search engines for Arabic language. To evaluate the performance of these services, a set of ontologies were used with pre-annotated documents related to those ontologies. the initial results show a promising performance which will support the research in the semantic web with respect to Arabic language.

Many Internet applications employ 3-tier software architecture such as e-commerce system. Starting from analyze the architecture of an e-commerce development platform model based on 3-tiered web, We present by using queuing network theory, we propose a reusable e-commerce development platform based on 3-tiered web. Finally, we implement the MVA algorithm withthe help of MATLAB and test the experimental data in LoadRunner benchmark.

the IPv6 network protects the IP layer by using the IPSec protocol and the SEND mechanism. However each host should be authenticated repeatedly when the two mechanisms are used at the same time. In this paper, we propose a cooperation scheme to share the authentication information between the SEND mechanism and the IPSec protocol. By sharing the authentication data of the host withthe SEND mechanism, IPSec protocol expects the cost reduction for establishing a secure communication channel. We also evaluate the performance of the proposed mechanism by implementing the cooperation scheme.

this paper presents a novel web Service-based approach to visualizing data from engineering fields. It will change the traditional mode, which makes use of local resources or single resource, into distributed visualization mode in order to implement the share and collaboration of computing resources, memory resources and data resources in heterogeneous environment. the possibilities and performance of the approach are analyzed. the process for visualizing engineering data, which is based on the web Service, is discussed, and the design and implementation of the web Services are explored. Finally, as a case study, the approach is evaluated by visualizing the data from ANSYS.

web applications have been developed from a simple static informationwebpage to a more complex web application, supporting complex processes and transactional workflows. the existing of numerous modeling concepts and design features in web applications, thus raises new issues on modeling approach. In this paper, we present and discuss the uses of user interaction diagram, object-oriented approach and Unified Modeling language (UML) notation for complex web applications. Our main objective is to propose a web application design model which is based on UML 2.0 profile and stereotypes. We propose user interaction diagram to capture users' information from use case diagram and specific UML modeling elements to model conceptual, navigational and user interface features of complex web applications. the uniqueness of our proposed design model stands in the design patterns modeling approaches. At the end of the paper, some future enhancements of the design model will be explained and briefly summarized.

While information retrieval (IR) and databases (DB) have been developed independently, there have been emerging requirements that both data management and efficient text retrieval should be supported simultaneously in an information system such as health care systems, bulletin boards, XML data management, and digital libraries. Recently DB-IR integration. issue has been budded in the research field. the great divide between DB and IR has caused different manners in index maintenance for newly arriving documents. While DB has extended its SQL layer to cope with text fields due to lack of intact mechanism to build IR-like index, IR usually treats a block of new documents as a logical unit of index maintenance since it has no concept of integrity constraint. However, towards DB-IR integration, a transaction on adding or updating a document should include maintenance of the postings lists accompanied by the document - hence per-document basis transactional index maintenance. In this paper performance of a few strategies for per-document basis transaction for inserting documents - direct index update, stand-alone auxiliary index and pulsing auxiliary index - will be evaluated. the result tested on the KRISTAL-IRMS shows that the pulsing auxiliary strategy, where long postings lists in the auxiliary index are in-place updated to the main index whereas short lists are directly updated in the auxiliary index, can be a challenging candidate for text field indexing in DB-IR integration.

Sequence labeling tasks, such as named entity recognition and part of speech tagging, are the fundamental compositions of the information extraction system, and thus received attentions these years. this paper proposes k-similar conditional random fields for semi-supervised sequence labeling, and makes use of unlabeled data to calculate the similarity between words with distributional clustering. the named entity recognition experiments show that this method can improve the performance through unlabeled data.
