Interactive Tools for Lessons Development in Collaborative eLearning Systems

Interactive Tools for Lessons Development in Collaborative eLearning Systems

Authors: Mircea Mărginean, Teodor Ştefănuţ
( 9 downloads)
Abstract

Current direction in the development of eLearning systems is mainly oriented towards creating collaborative lessons using interactive tools. The teacher has the possibility to create the lesson using interactive tools while the students can use it in running mode in a collaborative way, very similar to a lesson organized in the classroom, where the teacher can interact with his students in real time. This paper presents different types of interactive tools, their development methodology and their integration into already existing eLearning systems. Have been studied, developed and integrated the following types of tools: text visualization, image visualization, video visualization. Each tool is composed of two modules: the edit module – available to the teacher only, and the visualization module – available to the teacher as well as to the students. One of the problems that have been discussed in this paper was the maximization of the space available to the visualization module and, at the same time, the minimization of the space available for the editing module. Another problem discussed here concerns the proposal of a base standard for the modular development of the tools, so this process to be kept independent against the eLearning platform where the tools will be eventually integrated.

Improving a eLearning system Using Specific Elements of a Question-Answering System

Improving a eLearning system Using Specific Elements of a Question-Answering System

Abstract

Today Web developers try to create customized Web pages that are specific for every user, based on characteristics such as their interests, social class they belong to them or the context in which they access the pages. Web application that we built it helps the two categories of users (students and teachers) to communicate more easily from a distance. One of the basic components of this system identifies similar questions posted by students on basis of the question type and answer type and based on common keywords. This component helps the student first, because it can quickly get an acceptable answer to his question, from a similar question that already exist in the system, with already responded from the teacher. Secondly it helps the teacher, because when a student no longer wishes to answer the question (being satisfied with the answer given), he can mark the question to not longer is forwarded to the teacher. In this way, the system automatically reduces the number of questions requiring a response from the teacher.

Improve the Relevance of Search Engine Results Using Semantic Information from Wikipedia

Improve the Relevance of Search Engine Results Using Semantic Information from Wikipedia

Authors: Cristina Șcheau, Traian Rebedea, Costin Chiru, Ştefan Trăuşan-Matu
( 10 downloads)
Abstract

Depending on the user’s intention, the queries processed by a search engine can be classified in transactional, informational and navigational. In order to meet the three types of searches, at this moment search engines basically use algorithmic analysis of the links between pages improved by a factor that depends on the number of occurrences of the keywords in the query and the order of these words on each web page returned as a result. For transactional and informational queries, the relevance of the results returned by the search engine may be improved by using semantic information about the query concepts when computing the order of the results presented to the user. Wikipedia is a huge thesaurus which has the advantage of already being multi-lingual and semi-structured, presenting a dense structure of internal links that can be used to extract various types of information. This paper proposes a method to extract semantic relations between concepts considered as the names of the articles from Wikipedia, and then use these relations to determine the rank of the results returned by a search engine for a given query.

Evaluation and Automatic Summarization of Chat Conversations

Evaluation and Automatic Summarization of Chat Conversations

Authors: Mihai Dascălu, Ștefan Trăușan-Matu, Philippe Dessus
( 10 downloads)
Abstract

With the continuous evolution of collaborative environments, the need for automatic analysis and participant assessment in Instant Messenger discussions (chats) has become more and more important. Moreover, a key element in a grading and evaluation system for participants and utterances is summarization. In order to achieve the previous goals, a series of factors specific to natural language processing (including semantic analysis by means of Latent Semantic Analysis - LSA) and data-mining were taken into consideration. In order to achieve a thorough and multi-perspective approach for assessing participants, the system includes facilities derived from Page’s essay grading techniques, readability assessment and metrics specific to social networks analysis. A golden standard was used for assessing the relevance of the obtained results and for validation purposes of the proposed method.

Location-based Services Personalization Using Genetic Algorithms and Intelligent Agents

Location-based Services Personalization Using Genetic Algorithms and Intelligent Agents

Authors: Liviu Adrian Cotfas, Andreea Dioșteanu
( 10 downloads)
Abstract

This article analyzes possible solutions for improving Location-based Services (LBS) by using genetic algorithms and intelligent agents. The proposed solution enables identifying the points of interest based on the user profile and on the current context, and also generating routes in multi-modal and multi-operator public transport networks. The route generator process is based on a genetic algorithm that offers users the possibility to have a flexible restriction set for quantifying the importance degree of each associated optimization criterion. Therefore, we add an additional level of personalization over the exclusive use of fixed constraints set in the route identification process. The points of interest are represented by using intelligent agents and the communication between them is realized with the help of predefined ontologies.

Extracting Implicit Opinions of Economic Texts

Extracting Implicit Opinions of Economic Texts

Authors: Claudiu Cristian Muşat, Ştefan Trauşan-Matu
( 9 downloads)
Abstract

We propose a new approach to opinion mining that relies not on explicit occurrences of opinions in economic texts but on implicit ones extracted from the polarity of the discussed economic subtopic. We begin by dynamically generating a financial text corpus, following outgoing links from a set of financial web pages and then by checking whether economic topics are discussed. We separate economic from non economic texts by searching for key expressions from a database built beforehand. In the second phase we prove that the majority of economic texts that contain personal opinions can be retrieved based solely on the implicit opinions within. We rely on co-occurrences of economic indicators and future state modifiers to determine the polarity of each text. We also present an extraction method for the said key terms.

Interactive Components in a Environment for Grid Applications Development

Interactive Components in a Environment for Grid Applications Development

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

The degree of usability of the Grid applications by specialists in other fields than computer science is low. This is due to the lack of interactive components integrated in the Grid platforms that allow a transparent access to Grid infrastructure. The majority of the Grid applications may only be used through command line scripts. An environment for Grid application development should provide interactive components for data management and workflows on Grid and interactive components for development and inclusion of operators. In this paper we present an architecture of such a development environment with emphasis on interaction techniques and interactive components.

Task Modeling at Operational Level in the Context of Model-based Design

Task Modeling at Operational Level in the Context of Model-based Design

Authors: Costin Pribeanu
( 10 downloads)
Abstract

In the context of model-based design of user interfaces it is important to pay attention to the modelling of all relevant aspects as well as to the specification of relationships between models. The task model has a particular importance since it mediates the relationship between the domain model and the presentation model. The purpose of this paper is to approach task modeling at operational level from a broader perspective, defined by the activity theory and the reference model for multi-target user interfaces.

Using Software for Decoding and Analysis of Physiological Reactivity in Human Higher Cognitive Processes

Using Software for Decoding and Analysis of Physiological Reactivity in Human Higher Cognitive Processes

Abstract

The scientific data obtained by the polygraph technique concerning the human psychophysiological reactivity has been disputed by a part of the scientific community, who invoke the lack of consistent theories which would sustain the existence of clear, causal links between the cognitive processes involved in simulation and the measured physiological peripheral parameters (respiratory parameters, cardiovascular parameters, galvanic skin response). In this context, neurosciences are all the more looked upon to explain the approach of the cognitive level of simulated behavior, in the attempt to understand the neurophysiological basis of the underlying mental processes. This article emphasises the utility of the LX 4000- version 9.9.5. used by the Lafayette model 4000 polygraph in detecting and analising the human psychophysiological reactivity to different stimuli and during superior cognitive processes. The conclusions of this article demonstrate that the operationalization of these technologies must be synchronized with the fundamental research which targets the elaboration of solid scientific theories concerning simulated behavior.
