This paper would like to introduce Second Life ® (SL) as a virtual platform for foreign language education. SL is a 3D virtual world accessible via the Internet. A free client programme enables its users to interact with each other through ‘Avatars’. An ‘avatar’ is the graphical representation of a computer user representing himself/herself or alter ego. Recent literature in the field endorses ...

thesis describes the design, implementation, and evaluation of optimization techniques in a Java Just-In-Time (JIT) compiler. These optimization techniques avoid the overhead incurred because of type safety and polymorphism for supporting reusability and safety of programs in the Java language. Consequently, Java can achieve the same runtime performance as the familiar C and C++ languages. The ...

The development of realistic virtual actors in many applications, from user interface to computer entertainment, creates expectations on the intelligence of these actors including their ability to understand natural language. Based on our research in that area over the past years, we highlight specific technical aspects in the development of language-enabled actors. The embodied nature of virtu...

In this paper a three-dimension web-based modeling technique is introduced. VRML (Virtual Reality Modeling Language) and other 3D modeling technique are applied to develop virtual reality model database of engineering drawing on internet.

This paper briefly describes four cognitively-related aspects of modeling a virtual patient: interoception, decision-making, natural language processing and learning. These phenomena are treated within the Maryland Virtual Patient simulation and training environment.

This paper adopts JSP dynamic development language, struts2 core framework implements open online virtual experiment teaching platform system, the system using virtual reality technology to simulate the real experiment, include the experiment simulation platform and virtual experiment teaching management system. The simulation platform builds virtual experiment environment, so that the students...

The Open Language Archives Community (OLAC) is an international partnership of institutions and individuals who are creating a worldwide virtual library of language resources. The Dublin Core (DC) Element Set and the OAI Protocol have provided a solid foundation for the OLAC framework. However, we need more precision in community-specific aspects of resource description than is offered by DC. F...

We discuss interaction modalities in web-based virtual environments. We argue that the language behaviour of users in virtual environments differs essentially from language behaviour in the context of other spoken dialogue systems. Allowing different modalities will also ask for a model that allows user and system to expect that knowledge obtained from previous interactions is available to what...

With the rise of domain-specific languages (DSLs), research in language implementation techniques regains importance. While DSLs can help to manage the domain’s complexity, it is rarely affordable to build highly optimizing compilers or virtual machines, and thus, performance remains an issue. Ideally, one would implement a simple interpreter and still reach acceptable performance levels. RPyth...

virtual water adds a new dimension to crop trades and provides a new way of thinking about water scarcity. a systematic analysis of virtual water flows requires integration of all critical drivers of virtual water flows under a single consistent framework. the aim of this study was to assess virtual water flows related to trades of grain crops (wheat, corn, rice, and coarse cereals) and their i...
