The task of assigning geographic coordinates to textual resources plays an increasingly central role in geographic information retrieval. The ability to select those terms from a given collection that are most indicative of geographic location is of key importance in successfully addressing this task. However, this process of selecting spatially relevant terms is at present not well understood, and...
This paper proposes a new layer for a novel IPTV service that is focused on the distribution of personalized multimedia contents over IP networks based on the concept of content-zapping, in contrast to traditional channel-zapping. Our system aims to aggregate continuously the available multimedia contents in its providers and suggest them efficiently to its endusers. Thus, the system will allow users...
BBSs (Bulletin Board Systems) and Social Network Services (SNS) have been increasing in recenter years. In such systems, users can easily upload and share their own information via personal computers, and also cellular phones. However some information, such as adult content, is not appropriate for all users, notably children. Many SNS and BBS providing companies have been trying to monitor and check...
The continuing explosive growth of textual content within the World Wide Web has given rise to the need for sophisticated Text Classification (TC) techniques that combine efficiency with high quality of results. E-mail filtering is one application that has the potential to affect every user of the internet. Even though a large body of research has delved into this problem, there is a paucity of survey...
The massive use of technologies has spurred a new revolution in Interactive Information system. This research is being conducted to address the integration of cultural factors to enhance the reach of information access, which is caused by the ambiguity of cultural terminology. In this context, we study cultural differences in categorization and classification by means of card sorting experiments in...
The problem of inferring geographical information associated to web pages and identifying the geographic scope of their content is gaining increasing attention. However, geographic scope is a concept that can be interpreted in many different ways, ranging from the expected target scope of a specific content to the country where the content originated. The latter, in particular, albeit difficult to...
The paper outlines a model for framing the representation and treatment of information gathered from the reuse and repurposing of learning resources from distributed repositories. The model takes into account as sources of information both static user-edited or automatically generated metadata fields and the emerging, dynamic information clouds that surrounds a learning resource when users comment...
Privacy has been recognized as a critical topic in the Internet for a long time, and technical developments in this area are ongoing. With the proliferation of various network sites and the unification of them, it has become more evident that the problem of privacy is not bounded by the perimeters of a specific system. Nowadays, many network services rapidly drive toward unification. In this paper,...
Tagging is one of the most popular services in Web 2.0. As a special form of tagging, social tagging is done collaboratively by many users, which forms a so-called folksonomy. As tagging has become widespread on the Web, the tag vocabulary is now very informal, uncontrolled, and personalized. For this reason, many tags are unfamiliar and ambiguous to users so that they fail to understand the meaning...
This article presents a concept model, and the associated tool to help advanced learners to find adapted bibliography. The purpose is the use of an IT representation as educational research software for newcomers in research. We use an ontology based on the ACM's Computing Classification System in order to find scientific articles directly related to the new researcher's domain without any formal...
