Finding Tours for a Set of Interests

2018

This paper addresses a novel tour discovery problem in the domain of travel search. We create a ranking of tours for a set of travel interests, where a tour is a group of city documents and a travel interest is a query. While generating and ranking tours, it is aimed that each interest (from the interest set) is satisfied by at least one city in a tour and the distance traveled to cover the tour is not too large. Firstly, we generate tours for the interest set, by utilizing the available ranking of cities for the individual interests and the distances between the cities. Then, in absence of existing methods directly related to our problem, we devise our novel techniques to calculate ranking…

Looking Beyond Genres: Identifying Meaningful Semantic Layers from Tags in Online Music Collections

2011

A scheme for identifying the semantic layers of music-related tags is presented. Arguments are provided why the applications of the tags cannot be effectively pursued without a reasonable understanding of their semantic qualities. The identification scheme consists of a set of filters. The first is related with social consensus, user-count ratio, and n-gram properties of tags. The next relies on look-up functions across multiple databases to determine the probable semantic layer of each tag. Examples of the semantic layers with prevalence rates are given based on application of the scheme to a subset of the Million Song Dataset. Finally, a validation of the results was carried out with an i…

Semantic traffic applications based on DatexII

2009

In this work we demonstrate a particular use of ontologies based on the European specifications DATEXII. These specifications are designed and developed as a traffic and travel data exchange mechanism by a European task force to set up and standardise the interface between traffic control and information centres. It is the reference for applications that are developed and implemented in Europe.This language describes concepts and structures of data related to traffic, but the description is just syntactic, not semantic. Therefore the objective to be reached in this part of the research has been to develop a semantic description in order to carry out some applications like syndication and a …

Mobile agents, globus and resource discovery

2004

Publisher Summary This chapter discusses grid technology and some related problem. The overview of grids, in terms of application fields and needed protocols is given. The common feature of all grid architectures is a coordinated and controlled resource sharing between the members of a dynamic multi-institutional virtual community. The members of such a community agree on which resources will be shared and which members of the community will be enabled to access these resources, thus defining a set of sharing rules and permissions. The Globus project is discussed, which is nowadays the de facto standard for grid environments, with emphasis on its resource discovery components. Finally, the …

Detection of Anomalous HTTP Requests Based on Advanced N-gram Model and Clustering Techniques

2013

Nowadays HTTP servers and applications are some of the most popular targets for network attacks. In this research, we consider an algorithm for HTTP intrusions detection based on simple clustering algorithms and advanced processing of HTTP requests which allows the analysis of all queries at once and does not separate them by resource. The method proposed allows detection of HTTP intrusions in case of continuously updated web-applications and does not require a set of HTTP requests free of attacks to build the normal user behaviour model. The algorithm is tested using logs acquired from a large real-life web service and, as a result, all attacks from these logs are detected, while the numbe…

WEB-SITES QUALITY AND BUSINESS PERFORMANCE: AN EMPIRICAL INVESTIGATION IN THE SICILIAN WINERIES

2015

In recent years, several enterprises in different sectors have adopted e- business models exploiting the potential offered by ICT and particularly by the internet. As many authors have highlighted, web presence offers enterprises important opportunities which are linked to overcoming spatiotemporal and cost limits which characterize traditional means of communication. This study aimed to analyze how the web marketing is used in Sicilian wineries, and the relationship between the quality of content and features of websites to their business revenue. results show a different approach to web marketing by wineries which use the net as a mere tool to promote their image, to increase their visibi…

Web site quality: an empirical study of the flower and plant firms in the Convergence objective Regions in Italy

2012

In the last few years the growing diffusion of ICTs has been playing a crucial role in the developmental process of the economic, social and cultural fabric, by deeply affecting organization size of firms. The present research, which is set in the framework of “Business to Consumer” relationships, plans to analyze web marketing strategies adopted by flowers and ornamentals firms of Italian Convergence Regions. In particular, the study aims to analyze the websites factors that are able to draw the consumers’ attention and to influence their decisions, as well as the number of attributes which determine as a whole the “quality” of a website. The knowledge of these aspects is extremely useful …

No. of bitstreams: 0 Previous issue date: 2013-02-07 Background: Functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. Large bodied frugivores may disperse similar plant species and have strong impact on plant recruitment in tropical forests. Th…

The Embioptera from the Strait of Sicily Islands: first records from Pantelleria and Lampedusa and new data from Lampione (Sicily, Italy)

2021

The occurrence of Embioptera in the Strait of Sicily islands was up to date known only from Lam pione (the smallest of the Pelagie islands), where the only species reported was provisionally assigned to Embia ramburi Rimski-Korsakow, 1905. Based on material recently collected by the authors, the presence of Embioptera is here reported for the first time in the Islands of Pantelleria (Sicily, Trapani) and Lampedusa (Sicily, Agrigento). In the Island of Pantelleria the occurrence of the typical small silky tunnels produced by Embioptera has been verified in many sites, from sea level to Montagna Grande (836 m). In many of these sites, several juveniles and some adult or subadult specimens wer…
