Interoperability between Distributed Systems and Web-Services Composition
2009
An information system is a multi-axis system characterized by a “data” axis, a “behavioral” axis, and a “communication” axis. The data axis corresponds to the structural and schematic technologies used to store data into the system. The behavioral axis represents management and production processes carried out by the system and corresponding technologies. The processes can interact with the data to extract, generate, and store data. The communication axis relates to the network used to exchange data and activate processes between geographically distant users or machines. Nowadays, technologies required for interoperability are extended to deal with the semantic aspect of the information sys…
Content Production Strategies for E-Government
2008
The terms electronic government (e-government) and digital government are used to refer to the utilization of the Internet and other information and communication technologies (ICT) effectively in public sectors. In e-government development activities, the concern is often in building new means to support and strengthen democracy (e.g., Watson, Alselsen, Evjemo, & Aarsæther, 1999). In other cases, the main concern may be in supporting the work of people in public sectors (e.g., Mustajärvi, 2003), or in building new kinds of services for citizens (e.g., Lyytikäinen, Tiitinen, & Salminen, 2000). Common to most development activities is the need to have the content of public sector inf…

Tracing Potential School Shooters in the Digital Sphere
2010
There are over 300 known school shooting cases in the world and over ten known cases where the perpetrator(s) have been prohibited to perform the attack at the last moment or earlier. Interesting from our point of view is that in many cases the perpetrators have expressed their views in social media or on their web page well in advance, and often also left suicide messages in blogs and other forums before their attack, along the planned date and place. This has become more common towards the end of this decennium. In some cases this has made it possible to prevent the attack. In this paper we will look at the possibilities to find commonalities of the perpetrators, beyond the fact that they…
Search Interfaces and Learning about Controversial Topics
2019
Search engine results pages (SERPs) are a frequent gateway to Internet content. Prior research has extensively documented strong effects of SERPs (e.g. rank order or the spatial distribution of the results) on users' attention to and selection of particular Web pages [1,2]. In the context of Web search, a common user behavior is the 'top link' or 'Google trust' heuristic, that is, the inspection and selection of only the first few search results presented by the search engine, without evaluating all other search results available. This heuristic behavior allows users to find information in an efficient way, as search engines tend to provide relevant documents on top of the list, especially …
Semantic Annotation and Retrieval of Services in the Cloud
2013
Recently, the economy has taken a downturn, which has forced many companies to reduce their costs in IT. This fact has, conversely, benefited the adoption of innovative computing models such as cloud computing, which allow businesses to reduce their fixed IT costs through outsourcing. As the number of cloud services available on the Internet grows, it is more and more difficult for companies to find those that can meet their needs. Under these circumstances, enabling a semantically-enriched search engine for cloud solutions can be a major breakthrough. In this paper, we present a fully-fledged platform based on semantics that (1) assist in generating a semantic description of cloud services…
A novel policy-driven reversible anonymisation scheme for XML-based services
2015
Author's version of an article in the journal: Information Systems. Also available from the publisher at: http://dx.doi.org/10.1016/j.is.2014.05.007 This paper proposes a reversible anonymisation scheme for XML messages that supports fine-grained enforcement of XACML-based privacy policies. Reversible anonymisation means that information in XML messages is anonymised, however the information required to reverse the anonymisation is cryptographically protected in the messages. The policy can control access down to octet ranges of individual elements or attributes in XML messages. The reversible anonymisation protocol effectively implements a multi-level privacy and security based approach, s…
El uso político de Twitter en la campaña de las Elecciones Locales de 2015 en la ciudad de València
2020
La investigación analiza el uso político de Twitter en la campaña de las Elecciones Locales de 2015 en la ciudad de Valencia. El trabajo realiza una comparación de la presencia y de la actividad en dicha red de microblogging de las cinco formaciones políticas que obtuvieron representación en la corporación municipal (el Partido Popular, Compromís, Ciudadanos, PSPV-PSOE y València en Comú) y sus respectivos candidatos (Rita Barberá, Joan Ribó, Fernando Giner, Joan Calabuig y Jordi Peris). Lo hace mediante una metodología de análisis cuantitativo ya consolidada y que resulta especialmente conveniente para documentar la progresiva implantación de las aportaciones potenciales de la comunicación…
Prank – gdzie przebiega gra-nica internetowej rozgrywki?
2019
Artykuł podejmuje temat pranku – gry, która podbija obecnie internet, a dokładnie przestrzeń wideoblogów, gdzie realizuje się z największym rozmachem. Celem tekstu jest zdefiniowanie pojęcia pranku przede wszystkim w odwołaniu do jego przedstawień w wideoblogach. Istotną część wywodu stanowi ukazanie przebiegu pranków uznanych za najbardziej ekstremalne – pozorujące śmierć, wypadek, ciążę, odurzenie itp. Całość rozważań zmierza do odpowiedzi na pytania: czy można wyznaczyć granice owej gry? Czy grających obowiązują jakiekolwiek normy i ograniczenia? I wreszcie – jakie są lub mogą być niepożądane skutki tej rozgrywki?
Latviešu influenceru priekšstati par atbildību auditorijas priekšā, publicējot apmaksātu saturu sociālajā tīklā YouTube
2019
Bakalaura darba “Latviešu influenceru priekšstati par atbildību auditorijas priekšā, publicējot apmaksātu saturu sociālajā tīklā YouTube” galvenais mērķis ir noskaidrot latviešu YouTube influenceru izpratni par atbildību publicējot apmaksātu saturu un cik ļoti tas atbilst novērojumiem viņu YouTube kanālos. Darba teorētisko daļu veido trīs nodaļas – sociālie mediji, reklāma internetā un medijpratība. Darba empīriskajā daļā izmantota kontentanalīze, lai analizētu četru YouTube kanālu saturu 2019. gada februāra – marta griezumā. Pēc tam izmantotas daļēji strukturētās intervijas, lai intervētu blogu autorus. No pētījuma rezultātiem izriet vairāki secinājumi, kas parāda to, ka influenceri lielu …
