Ch.A.M.P.– Modeling and Assessment System for Chat Evalution

Ch.A.M.P.– Modeling and Assessment System for Chat Evalution

Authors: Mihai Dascălu, Ştefan Trăuşan-Matu
( 10 downloads)
Abstract

The paper presents a system developed to assess the skills and evolution of participants in a collaborative environment. To obtain an overall approach, two scenarios have been considered: quantitative approach based on social networks and number of interchanged utterances between participants and the second, qualitative, based on the semantic content analysis of each utterance. Thus, metrics specific for social networks have been applied on the graph obtained after evaluating each utterance under contextual relevance using methods for text mining, natural language processing and latent semantic analysis.An important component of the system is the visualization module which makes possible the modeling and evolution of social networks. A specific view can be generated in order to analyze the whole chat, a discussion thread, the prospective growth/evolution of each participant, and can highlight the contribution of each participant through the statistics generated by the various metrics applied. Other modules have been developed to evaluate and annotate each chat in order to obtain the “golden sample”, to compare notes with the results obtained from automatic analysis and to learn from the corpus using WordNet and LSA.

Theories and models for technology acceptance

Theories and models for technology acceptance

Authors: Alexandru Balog, Irina Cristescu
( 10 downloads)
Abstract

The user acceptance of new technologies and systems is a topic of interest for many researchers working in various areas. In this paper we present the main theories employed in assesing the technology acceptance (theory of reasoned action, theory of planned behavior) as well as the technology acceptance models that have been developed on the basis of these theories. The focus is on the model constructs and, implicitely, on the hypotheses that have to be tested in order to validate the technology acceptance models in different contexts of use.

Mirrors of the World – Supporting Situational Awareness with Computer Screens

Authors: Gerrit C. van der Veer, Olga Kulyk and Dhaval Vyas
( 10 downloads)
Abstract

In this paper we develop a notion of support for social and situational awareness. Our initial ideas are based on the metaphor of using a mirror to see what you are not looking at. We provide two studies that, for different contexts, apply the metaphor to develop design ideas that fit the context of use.

New directions in UI: WPF and Silverlight

New directions in UI: WPF and Silverlight

Authors: Dan Petric, Daniel Lăcătuş, Stefan Szasz
( 10 downloads)
Abstract

Windows Presentation Foundation, or WPF, is the new framework for UI development included in the .NET 3.0+ technologies, aiming to replace the older Windows Forms Framework. With a special Direct 3D based engine, the new framework offers support for video streaming and 3D operations together with other graphical visual effects that where impossible to achieve in the old Window Forms. Silverlight is another framework designed to support the development of web applications with a very attractive interface. Implemented as a browser plugin, Silverlight allows these applications to run on the most of the operating systems being a more advanced environment that the DHTML (HTML and JavaScript) language. Both frameworks represent the new generation of instruments used for creating special and innovative User Interfaces, superior to the classical ones.

Creating And Visualizing Lessons In Egle Elearning Platform

Creating And Visualizing Lessons In Egle Elearning Platform

Authors: Teodor Ştefănuţ, Victor Bâcu, Dorian Gorgan
( 10 downloads)
Abstract

Together with the development of the Internet and with the large use of personal computers, the eLearning Platforms have known an accelerated development providing educational services to significantly lower costs than classical methods. Today, the development of these systems has been slowed down because of their limited processing and storage capabilities that can be used at once. Being used in new domains that require the management and processing of large volumes of information (ex. satellite images, 3D simulations etc.), the eLearning Environments based on single server architectures will be replaced by the ones based on Grid networks that will provide the capabilities necessary to perform this kind of operations. This paper will describe the eGLE eLearning Platform which has been created based on Grid technology and will also present a method to create lessons in Earth Observation domain using these extended storage and processing capabilities.

The Accesibility Of Elearning Platforms For The Visually Impaired Students

The Accesibility Of Elearning Platforms For The Visually Impaired Students

Authors: Marian Pădure
( 10 downloads)
Abstract

The accessibility of the interfaces, with which a student with visual impairments interacts, remains an unsolved issue. Even if, there have been elaborated and recommended various standards for web accessibility (e.g. W3C-WAI), and also for e-learning system (e.g. I.M.S.,E-Learn-ViP), these are present only at a primary level or not entirely acceptable. In our research we intended to evaluate two platforms e-learning throughout two methodological steps, with the help from students with visual imairments. The accessibility of an e-learning system is useful to all the users, not only to those with visual impairments.

The Components Of A Text To Speech System

The Components Of A Text To Speech System

Authors: Mihai Alexandru Ordean, Andrei Şaupe, Mihaela Ordean, Dorian Gorgan

Abstract

Converting words from written form into speakable forms strongly influences the performance of a text-to-speech (TTS) system. The text analysis component of a TTS system is responsible for parsing the language structure and meaning. It indicates all the knowledge about the text and reveals out the message. The core element of the text analysis component is the text parser which translates and disambiguates the human language and conveys the meaning among a potentially unlimited range of possibilities. In this paper the focus is on the text analysis component of a TTS system tailored for the Romanian language. Our goal is to produce an efficient parser of the written text and proper data structures to allow the tuning of the core unit selection component of our TTS system. We go beyond previous research by enhancing our parser with further computational efficiency and better output representation.

Synchronizing Video Sequences With Text Streams

Synchronizing Video Sequences With Text Streams

Authors: Dârdală Marian, Reveiu Adriana, Furtună Titus Felix

Abstract

The construction of multimedia applications assumes to control and to management the media streams. The most complex data type involved in the multimedia applications is the video type. To use such a multimedia resource there are end-user oriented solutions as in the case of specialized software components from the authoring multimedia software products. In this case the emphasis is: on the presenting scenario, on the composition, on the synchronizing of elements involved in the presentation. In the development of low level applications, that is when the developer wants to build its own module for video sequences development, he/she must implement the streams synchronization module too, and the synchronization of native streams, from the multimedia resource with the external streams of the multimedia resource. In this article we intend to show the solutions for representing of text external streams and for synchronizing them with audio streams and with the images of a video stream.

A Generic Component Approach For Dynamic Generation Of User Interfaces

A Generic Component Approach For Dynamic Generation Of User Interfaces

Authors: Frăsinaru Cristian, Ungureanu Vlad Costel
( 10 downloads)
Abstract

In this article, we describe a new technique for dynamically generating user interfaces, used for data visualization and editing. Based on the Model Driven Architecture (MDA) specifications we propose a solution composed of an abstract framework, which not only allows the integration between entities in the persistence layer with their visualization models, but also offers a mechanism for multiple implementations for various Java technologies. The results obtained in our projects that use this framework allow us to consider that the utilization of this technique significantly reduces the development cycle and insures an easier maintenance.

Abstract

The development of augmented reality (AR) technologies creates new opportunities and challenges for e-learning systems designers. An important goal of these new platforms is increasing the learning motivation of students. This paper presents an evaluation of motivational value of an AR scenario for learning biology. After user testing, qualitative and quantitative measures have been collected, which asses the educational and motivational value of the learning scenario. While the results validity is sustained by the comparison between the two types of measures, the qualitative measures also offer and a detailed description of user learning experience.
