On Topological Structure of Web Services Networks for Composition. In Int. Journal of Web Engineering and Technology

2013

In order to deal efficiently with the exponential growth of the Web services landscape in composition life cycle activities, it is necessary to have a clear view of its main features. As for many situations where there is a lot of interacting entities, the complex networks paradigm is an appropriate approach to analyze the interactions between the multitudes of Web services. In this paper, we present and investigate the main interactions between semantic Web services models from the complex network perspective. Results show that both parameter and operation networks exhibit the main characteristics of typical real-world complex networks such as the "small-world" property and an inhomogeneou…

SIMILARITY NETWORK FOR SEMANTIC WEB SERVICES SUBSTITUTION

2013

Web services substitution is one of the most challenging tasks for automating the composition process of multiple Web services. It aims to improve performances and to deal efficiently with Web services failures. Many existing solutions have approached the problem through classification of substitutable Web services. To go a step further, we propose in this paper a network based approach where nodes are Web services operations and links join similar operations. Four similarity measures based on the comparison of input and output parameters values of Web services operations are presented. A comparative evaluation of the topological structure of the corresponding networks is performed on a ben…

Semantic Web Services for Smart Devices Based on Mobile Agents

2005

Among traditional users of Web resources, industry has a growing set of smart industrial devices with embedded intelligence. Just like humans, they need online services (i.e., for condition monitoring, remote diagnostics, maintenance, etc.). In this paper, we present one possible implementation framework for such Web services. Such services should be Semantic Web enabled and form a Service Network based on internal and external agents’ platforms, which can host heterogeneous mobile agents and coordinate them to perform needed tasks. The concept of a “mobile service component†assumes not only exchanging queries and service responses, but also delivering and composition of a service pro…

ECONOMICAL SYSTEMS - NEW TRENDS FOR APPLICATION INTEROPERABILITY

2012

Web Services and Service Oriented Architecture (SOA) registered an important increase in the past years. The aim of the Paper is to analyse the manner in which these technologies are used by the local business and how they can lead to the improvement of processes within enterprises. The paper includes the results of a study dedicated to determine the level of usage of these technologies in Romanian companies.

A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS

2016

Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…

Tieteelliset laskentasovellukset ja pilvipalvelut – erityistarkastelussa AWS

2014

Perinteisesti IT-resurssien hankinta on tapahtunut hankkimalla laitteistoa ja ohjelmistoja omaan tai organisaation omistukseen. Näiden resurssien käyttö on yleensä tarkoittanut merkittäviä investointeja laitteistoihin, ohjelmistoihin ja näiden ylläpitoon. Suuressa organisaatiossa kalliiden IT-resurssien käyttöönotto voi olla joissain tapauksissa hyvinkin byrokraattinen prosessi. Tieteellinen laskenta edellyttää usein erittäin suurta laskenta- ja tallennuskapasiteettia. Tutkijat hyötyisivät raskaaseen laskentaan vaadittavien IT-resurssien hankkimisesta palveluna, jolloin usein niukat resurssit voitaisiin keskittää vaadittavan laitteiston hankkimisen ja ylläpidon sijaan ydinongelman tutkimise…

Music adviser : emotion-driven music recommendation ecosystem

2017

In respect of the big amounts of music available in the web, people met the problem of choice. From another side, practically unlimited resources can bring us new opportunities in the music context. Efficient data management engines which are smart and self managed are in demand nowadays in the music industry to handle music sources amounts of which are coming towards to infinity continuously. This study demonstrates feasibility of the emotional based personalization of music recommendation system. There is still gap between human and artificial intelligence, robotics do not have intuition and emotions which represent critical point of recommendations. Taking into account significant influe…
