The use of Virtual Reality in Education based on Web3D gives us a new thought of teaching methodology, providing us with easier way to study and learn things wherever we can get on the Internet at anytime. Web3D technologies can both augment Web sites with 3D interactive contents and display other contents available in the Web. In this paper, we design a system framework using miscellaneous technologies...
In recent years, the explicit semantic analysis (ESA) method has got a good performance in computing semantic relatedness (SR). However, ESA method has failed to consider the given context of the word-pair, and generates the same semantic concepts for one word in different word-pairs. It canpsilat exactly determine the intended sense of an ambiguous word. In this paper, we propose an improved method...

Many websites on the Internet offer services to people. They usually ask the users to fill the registration forms for using their services. Unfortunately, some vandalistic persons write programs which make automatic fake registration. For solving this problem, CAPTCHA (Completely Automated Public Turing test to tell Computers and Human Apart) systems are invented. These systems distinguish human users...
Nowadays the Internet users are from different ages and groups. The disabled people also use the Internet. Some Web sites are especially created for disabled people. Many Internet sites offers services for human users, but unfortunately some computer programs are designed to abuse these services. To solve this problem, some systems named CAPTCHA (completely automated public Turing test to tell computers...
In some websites it is necessary to distinguishing between human users and computer programs which is known as CAPTCHA (Completely Automated Public Turing test to tell Computers and Human Apart). CAPTCHA methods are mainly based on the weak points of OCR systems and using them are undesirable to human users. In this paper a method has been presented for distinguishing between human users and computer...
In distributed Web authoring, shared documents can be accessed concurrently by multiple authors who must be coordinated to avoid conflicts. The current Web standard for distributed authoring and versioning uses a two-phase locking to coordinate concurrent access. As the degree to which authors work concurrently may vary though among cooperative sessions, it is necessary to extend the aforementioned...
