Ontology-based Collaborative Applications

Ontology-based Collaborative Applications

Authors: Vlad Posea, Ovidiu Mara
( 10 downloads)
Abstract

his paper proposes a method to extend a collaborative application with semantic web technologies in order to provide advanced functionalities for searching and classification of messages based on the semantics of the terms identified in the messages exchanged by the user. The paper also describes a specific extension to a forum that offers an improved interface for defining semantic ontology based querying.

Management of the Temporal Maps within a Collaborative Environment

Management of the Temporal Maps within a Collaborative Environment

Authors: Cosmin Vârlan
( 9 downloads)
Abstract

GPS are usually built by only one company that provides the software and the maps as a single solution. Because the maps are made especially for that kind of software and because the format is not made public, to update such a map additional files (from the producer) are needed. Even though, the producer is not always updating all the roads as fast as they appear or as fast as their properties are changing. This paper is proposing a new method of creating maps which provide the dynamism needed by every GPS: the maps are created by every driver, collected on the same website, parsed and modified and redistributed to the other users that are interested in vectorized maps. This way the maps are refreshed every day and that could be done even in real time.

Abstract

Augmented reality is featuring a new type of human-computer interaction that is based on the integration of the real and virtual within a single interaction space. More recently, these systems have been used to implement learning scenarios intended to support new teaching methods in secondary schools. This paper presents a comparative usability evaluation of two augmented reality learning scenarios. The evaluation is carried on the basis of the quantitative and qualitative measures provided by a usability questionnaire that is based on a technology acceptance model.

Authors: Titus Felix Furtună, Marian Dârdală
( 10 downloads)
Abstract

Java technologies cover at this moment all aspects concerning software developing. This paper proposes a software solution for real time vocal signal transmission using Java technologies. The proposed solution can be an alternative way for directly, simply and useful communication for people with visual disabilities. It is able to supply, in particular circumstances, more sophisticated and expensive technologies; for instance vocal synthesis. The paper contains a theoretical part that presents used Java technologies (Java Sound Application Programming Interface) and network programming aspects using the UDP protocol- and an applicative part that presents the elements of proposal software solution – the application architecture and significant sequences of source code.

Ignoring Irrelevant Information on Displays

Ignoring Irrelevant Information on Displays

Authors: Ion Juvină
( 10 downloads)
Abstract

This paper presents empirical and modeling work aiming to contribute toward a coherent theory of how humans select relevant information and discharge irrelevant information presented on displays. Two empirical studies are presented. The first study investigated how previously attended information is prevented from interfering with currently processed information. A theoretical account together with two different implementations of this account are put forward in order to explain the empirical data. A second study was designed in order to disentangle between these two implementations. The second study generated new questions and hypotheses regarding the balance between automatic and controlled discharge of irrelevant information.

Visual Communication through Infographics

Visual Communication through Infographics

Authors: Ecaterina Valică
( 10 downloads)
Abstract

Interaction techniques and visual representations allow users to view, explore and understand large amounts of information. The research made in Information Visualization area has focused on finding ways to render the abstract information in an more intuitive way. Infographics allows you to filter the information, establish relations between its components, find patterns and represent them in a manner that allows the consumer to assimilate knowledge in a faster and easier way. As infographics enter the on-line environment, the line between infography and software begins to blur. The ease of interpretation of information within an infographic is based on the fact that it uses a universal visual language. Lately we can use various tools for automatic representation and visualization of data. These tools facilitate the creation and distribution of infographics and make the transition from presentational to interactive graphics.

News Web Portal based on Natural Language Processing

News Web Portal based on Natural Language Processing

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

The paper presents an autonomous text classification module for a news web portal for the Romanian language. Statistical natural language processing techniques are combined in order to achieve a completely autonomous functionality of the portal. The news items are automatically collected from a large number of news sources using web syndication. Afterward, machine-learning techniques are used for achieving an automatic classification of the news stream. Firstly, the items are clustered using an agglomerative algorithm and the resulting groups correspond to the main news topics. Thus, more in-formation about each of the main topics is acquired from various news sources. Secondly, text classification algorithms are applied to automatically label each cluster of news items in a predetermined number of classes. More than a thou-sand news items were employed for both the training and the evaluation of the classifiers. The paper presents a complete comparison of the results obtained for each method.

A Microformats-based Tool for Personal Data Management

A Microformats-based Tool for Personal Data Management

Authors: Marius Butuc, Sabin-Corneliu Buraga
( 9 downloads)
Abstract

We found ourselves in a time when we experience a real blooming of the social side of the Web, by having more and more (apparently) separated entities communicate together. In order to be able to communicate easily and to be able to understand each other, we need standards that describe what we say, what we listen, what we store in our data. That is why the development of semantic markup doesn’t only enrich the meaning for the humans, but also the meaning of the human-defined semantic for the machines. The purpose of this paper is to introduce a Web application – Microwler – that is capable of helping people enrich their social experience on the Web. Microwler enables the user to search and retrieve the personal data that anyone made available, regardless of the rest of the content. It also enables the user to visualize the connections that person has in his/hers XHTML Friends Network (XFN).

Abstract

The paper presents an approach and an implemented system for analyzing the imaginary in texts. This problem is very important because its resolution allows the identification of connotations in texts, with major implications on textual interaction. The approach starts from the theory of imaginary introduced by the historian Lucian Boia. Natural language processing techniques are used. The results of analysis on several known books are presented and commented.
