GSM is a mobile technology that allows people to communicate with one another. The technology enables people to call others over the phone with a GSM number and a certain tariff for communication. An interpersonal GSM network is established by means of calls and text messages. This paper proposes an approach to recommend optimal tariffs to GSM users to maximize the total utility of individuals in...
Nowadays, Internet communication and especially informal Internet communication such as social networks, blogs, etc. is directing politic, economic, financial and social environments all over the world. Consequently, Internet monitoring is taking more and more scale particularly in Tunisia suffering from unsteadiness since the politic revolution in 2011. In a Tunisian context, Internet communication...
In subjectivity and sentiment analysis (SSA), there are two main requirements are necessary to improve sentiment analysis effectively in any language and genres, first, high coverage sentiment lexicon - where entries are tagged with semantic orientation (positive, negative and neutral) - second, tagged corpora to train the sentiment classifier. Much of research has been conducted in this area during...
The present paper deals with WEB-based notation, which implements a natural language representation of mathematical texts and preserves their semantics. We have developed a visualization of notation for browsers and its export to standard formats TeX, Content MathML and PDF. The suggested WEB-notation provides interactive communication over the Internet, as well as compatibility and interoperability...
Consumer devices increasingly are “smart” and hence offer services that can interwork with and/or be controlled by others. However, the full exploitation of the inherent opportunities this offers, is hurdled by a number of potential limitations. First of all, the interface towards the device might be vendor and even device specific, implying that extra effort is needed to support a specific device...
This study describes the design of a reference model for an instrument to measure quality of semantic Information System (IS) standards. This design satisfies requirements gathered among potential users, in a previous study. The reference model features three layers: concerned with quality, semantic IS standards, and the instrumentation, respectively. It serves as a basis for implementation of a quality...
The Internet of Things (IoT) refers to extending the Internet to devices such as home appliances, consumer electronics, and sensor networks. As multiple heterogeneous devices attempt to create area networks, one of the major challenges is the interoperability and composability of their services. The traditional way to address interoperability is to define standards; however, there are many standards...
The success of the collaborative web-based MediaWiki platform, widely used in several projects to exchange knowledge created a new idea to use this system as a low-tech interoperability and repository layer for data providers, end users, developers and project partners. Facilitating the acquisition of knowledge for multimedia digital resources is a task that usually requires special purpose interfaces...
From the requirements of inquiry ability in the informational era and new curriculum reform, this article analyzes the deficiencies of scientific inquiry in college, and then introduces the concept of cognitive tools and their features. In the end, it puts forward to the design of a web-based inquiry learning platform for college science education, which could provide references for similar researches.
The manual construction of e-Catalog ontologies which involves the acquisition, conceptualization, evaluation and formalization of domain dependent knowledge, has been largely identified as a costly, time-consuming, tedious and error prone task. In this paper, we provide a method of customer-oriented e-Catalog ontology automatic construction, by acquiring concept sets, identifying properties, learning...
Presence management, i.e., the ability to automatically identify the status and availability of communication partners, is becoming an invaluable tool for collaboration in enterprise contexts. In this paper, we argue for efficient presence management by means of a holistic view of both physical context and virtual presence in online communication channels. We sketch the components for enabling presence...
In the emerging e-Science scenario users should be able to easily combine data resources and tools/services; and machines should automatically be able to trace paths and carry out interpretations. Users who want to participate need to move from a down-load first to a cyberinfrastructure paradigm, thus increasing their dependency on the seamless operation of all components in the Internet. Such a scenario...
