Search engines have become the main way for people to get expected information, most of them are based on keyword search. However, keyword search is based on computing the similarity of letters of the keywords, instead of semantic meaning, therefore the searching results often include irrelevant information to user intention. this paper aims to find a way on improving keyword search efficiency. Using Wikipedia, which is the largest online encyclopedia, this paper explores the relations of terms through computing the semantic relatedness between words, and presents an algorithm called WLA in the light of link structure and text message in Wikipedia. What is more, we design a terms query platform through which users will be able to get all the meanings about the concepts. By making a comparison with lexical database WordNet, it has demonstrated the feasibility on our methods.

Personal agents are proactive and adaptable intelligent agents which meet the demands of individuals. the use of personal agents will become fully prominent when the intelligent agents are provided with mechanisms for understanding the contents of document they access. Making it possible for the intelligent agents to understand semantics of the documents published on the web is the central task in the development of the Semantic web. Possibility of application of Semantic web and the personal agents through distance education systems is elaborated in this paper. We also present adaptation of our distance education system DTEx-Sys (Distributed Tutor Expert system) for the use in environment of Semantic web and personal agents.
this paper analyses the current technical limitations in the monitoring web services which mainly focus on the lower layers rather than application layer in TCP/IP stacks. So, the paper puts forward an indicator and m...

In the era of big data, massive educational resources are stored on the internet and mobile networks. However, most of these resources are heterogeneous and decentralized, they have different format. the resources are designed for humans to read and not understandable to the machine. their low level sharing and reuse make them difficult to acquire. How to access the resources the users need quickly and efficiently and take advantage of them is a serious problem. In order to solve the problem, an ontology-based integration educational resources framework and sharing strategies are proposed. Using the advantages of ontological semantics these educational resources can be annotated semantically, so that the computer can understand and deal withthe marked information. the ontology-based integration and sharing strategies can improve the recall and precision of the educational resources retrieval.

this paper describes a development of rule-based webapplication to the problem of starting point selection in optical design. the system architecture is shortly discussed. A formalization of the optical system representation based on formal syntax is given. three examples of rules in natural language and Drools Rule Language syntax illustrate the work of the solution.

the spreading of wireless communication networks has brought a possibility to use the location information of the users in various applications. To make this possible, applications need APIs (application Programming Interface) for accessing the location information. the location information of a user is private information, which needs to be protected from misuse. For this reason, the user should have complete control over the usage of his own location information. there is a need for middleware systems which gather location information. provide an API for the services and allow users to authorize the use of their location information. this paper presents Location informationsystem (LIS), a middleware system for location based services in Wireless Local Area Networks (WLAN).

In this paper, a knowledge sharing system for teachers using a microcomputer based laboratory (MBL) was constructed and evaluated from the perspective of knowledge management to effectively graft MBL onto the existing education system. the knowledge sharing system permitted experienced educators a chance to share previously unrevealed information concerning the preparation, processing, and post stages of experiments with other teachers. the MBL was especially effective withthe cur-rent education system because the knowledge sharing system controlled for the many variables of experiments as well as the analysis of diverse experimental result. the subsequent web based knowledge sharing system of science experiments thus eased the sharing of information and provided an infrastructure of communication for active interchange of previously unstructured knowledge, know-hows and experience between members focused on problems occurring in the education field. It was assessed to be especially useful for the prediction and analysis of the different MBL experiment data according to the different control factors, so that it reduced errors and enhanced fast adaptation of the introduction of a new MBL environment.

As web technology has evolved, more and more enterprise applications become web-enabled. In order to secure websystems, a solution based on SMS (Short Message Service) for identifying users is put forward in this paper. As an additional identification of webapplicationsystems, especially sensitive webapplicationsystems, its implementation and advantage are discussed deeply. At the same time, a special case study, which this solution is applied to XOCECO Enterprise Portal, is given in detail.
the purpose of this research is to develop an application of Management informationsystem which is the State Owned Property Accounting informationsystem (SIMAK-BMN) by taking case study at the Regional Office of Dir...

Ajax is a new technology based on asynchronous communication between a client web browser and a back-end server, allowing webapplications to request data without webapplication to request and receive data ever reloading the page. We. designed and implemented the Ajax web archive application which supports to discover and analyze spacio-temporal structure of a sequence of sentences.
