We propose a novel approach of knowledge visualization method by adopting graph-based visualization technique and incorporating Dashboard concept for higher education institutions. Two aspects are emphasized, knowledge visualization and human-machine interaction. The knowledge visualization helps users to analyze the comprehensive characteristics of the students, lecturers and subjects after the clustering process and the interaction enable domain knowledge transfer and the use of the human's perceptual capabilities, thus increases the intelligence of the system. The knowledge visualization is enhanced through the dashboard concept where it provides significant patterns of knowledge on real-world and theoretical modeling which could be called wisdom. The framework consists of the system architecture and design for higher education environment is presented in this paper.

Towards ontology driven semantic conflicts detection in web services at message level

International Journal of Web Portals 2013年第3期5卷 71-80页

One of the biggest problems for establishing semantic interoperability is semantic conflicts, which prevent seamless message exchange between heterogeneous Web services. Consequently, numerous work has been done to establish semantic interoperability by solving semantic conflicts. However, the current work has not reached its maturity level to solve this problem effectively. Therefore, this paper proposes a new ontology driven approach to detect semantic conflicts between heterogeneous Web services at message level. This new approach will advance the process of establishing semantic interoperability in order to allow heterogeneous Web services to exchange their messages seamlessly. The main purpose of our approach is to detect the potential conflicts that occur during message exchange process. Copyright © 2013, IGI Global.

The rapid growth of computer technologies and the advent of the World Wide Web have increased the amount and the complexity of multimedia information. A content-based image retrieval (CBIR) system has been developed as an efficient image retrieval tool, whereby the user can provide their query to the system to allow it to retrieve the user's desired image from the image database. However, the traditional relevance feedback of CBIR has some limitations that will decrease the performance of the CBIR system, such as the imbalance of training-set problem, classification problem, limited information from user problem, and insufficient training-set problem. Therefore, in this study, we proposed an enhanced relevance-feedback method to support the user query based on the representative image selection and weight ranking of the images retrieved. The support vector machine (SVM) has been used to support the learning process to reduce the semantic gap between the user and the CBIR system. From these experiments, the proposed learning method has enabled users to improve their search results based on the performance of CBIR system. In addition, the experiments also proved that by solving the imbalance training set issue, the performance of CBIR could be improved.

In this work, we have performed sensitivity analysis on a large-scale dynamic metabolic network through MATLAB program. Time profile for sensitivity indices have been calculated for each kinetic parameters, based on percentage. The sensitivity analysis has been carried out on dynamic model for Glycolysis, Pentose Phosphate, TCA cycle, Gluconeogenesis, Glycoxylate pathways and Acetate formation of E. coli. The model implicates twenty four dynamic mass balance equations for extracellular glucose and intracellular, thirty kinetic rate expressions represent concentration profiles for whole a model. Each parameter has been scald one by one into 20% for the steady state condition. The former analysis has allowed identification of eight kinetic parameters as the most effective's ones on the complex metabolic network under study. © 2013 IEEE.

Storing XML documents in a relational database is a promising solution because relational databases are mature and scale very well and they have the advantages that in a relational database XML data and structured data can coexist making it possible to build application that involve both kinds of data with little extra effort. In this paper, we propose an algorithm schema named XRecursive that translates XML documents to relational database according to the proposed storing structure. The steps and algorithm are given in details to describe how to use the storing structure to storage and query XML documents in relational database. Then we report our experimental results on a real database to show the performance of our method in some features. © 2011 Springer-Verlag.

Weather is the most critical for human in many aspects of life. The study and knowledge of how weather Temperature evolves over time in some location or country in the world can be beneficial for several purposes. processing, Collecting and storing of huge amounts of weather data is necessary for accurate prediction of weather. Meteorological departments use different types of sensors such as temperature, humidity etc. to get the data. The sensors volume and velocity of data in each of the sensor make the data processing time consuming and complex. This project aims to build analytical Big Data prediction framework for weather temperature based on MapReduce algorithm. © 2016 IEEE.

The aim of this review is to study the methods of steganography using the video file as a cover carrier. The steganography is the art of protecting the information through embedding data in medium carrier, for instants this study illustrate historically this art, as well as the study describes methods as a review for this art in the video file. The video based steganography can be used as one video file, separated images in frames or images and audio files. Since that, the use of the video based steganography can be more eligible than other multimedia files. As a result of this study, the video based steganography has been discussed and the advantages of using the video file as a cover carrier for steganography have been proposed. © 2010 Asian Network for Scientific Information.

In this paper we present a middleware for storing and retrieving XML document in relational databases. To store XML documents in relational databases, several mapping prototypes can be used. I n this prototype we chose XParent model mapping method and free of cost available technologies MySQL, Php MyAdmin and PHP classes are used the example. The key to middleware prototype is storing and retrieving XML document in a relational database, providing a user interface for XML manipulation, independent of proprietorship and without doing any modification in its basic structure. As the proposed prototype is using XParent so it will be proved to be an efficient solution with respect to query processing specially recursive XML queries and updating. The middleware prototype can also be used as the benchmarking tool for the researchers to compare various schema-oblivious XML mapping strategies after adding them as new collection. © 2010 IEEE.

Uncertain and incomplete requirements throughout the whole software life cycle contribute to volatility of the requirements. In a situation where the volatile requirement is changed to satisfy stakeholder needs, all the affected requirements and other impacted software artefacts (such as designs, codes, and tests) must be identified and changed accordingly. This paper introduces an approach to facilitate both engineers and users in propagating changes from requirements to the software high-level designs during software development and evolution. The two main pillars of this approach, namely product metamodel and process model are described in details. Firstly, the metamodel highlights on explicit conceptual model for volatile requirement and its characteristics. Next, the focus will be placed on the systematic process model specified using the SPEM that offers guidelines to perform the requirement change process. The applicability of the product metamodel and its elements are evaluated using the IFAMMS case study application.
