Working with Multiple Ontologies on the Semantic Web.

2016

The standardization of the second generation Web Ontology Language, OWL, leaves a crucial issue for Web-based ontologies unsatisfactorily resolved: how to represent and reason with multiple distinct, but linked, ontologies. OWL provides the owl:imports construct which, roughly, allows Web ontologies to include other Web ontologies, but only by merging all the linked ontologies into a single logical "space". Recent work on multidimensional logics, fusions and other combinations of modal logics, distributed and contextual logics, and the like have tried to find formalisms wherein knowledge bases (and their logic) are kept more distinct but yet affect each other. These formalisms have various …

Students evaluating Internet sources – From versatile evaluators to uncritical readers

2008

The Internet is a significant information resource for students due to the ease of access it allows to a vast amount of information. As the quality of the information on the Internet varies, it is important that students are able to evaluate such information critically. The aim of the study was to investigate how students evaluate Internet sources in an authentic learning task. Upper secondary school students ( n = 25) were asked to look for source material on the Internet in order to write an essay. They were asked to verbalize their thoughts during the material gathering process. Their verbalizations and actions on the Internet were recorded and analyzed. The five evaluation profiles eme…

Challenges of Serendipity in Recommender Systems

2016

Most recommender systems suggest items similar to a user profile, which results in boring recommendations limited by user preferences indicated in the system. To overcome this problem, recommender systems should suggest serendipitous items, which is a challenging task, as it is unclear what makes items serendipitous to a user and how to measure serendipity. The concept is difficult to investigate, as serendipity includes an emotional dimension and serendipitous encounters are very rare. In this paper, we discuss mentioned challenges, review definitions of serendipity and serendipity-oriented evaluation metrics. The goal of the paper is to guide and inspire future efforts on serendipity in r…

INFORMATION QUALITY PROBLEMS ON WEBSITES

2019

The goal of this publication is to identify and characterize the typical problems with information quality on websites, and to present exemplary remedies for those problems. In this article the information quality problems within their origins, as well as the consequences of using poor-quality information by the Internet user were defined. There were also presented ways of improving information quality - which should facilitate the information needed by producers/authors and the managers/administrators of services in or to find solutions to the remaining problems. The presented varied remedies are not all possible solutions to improving quality in the area of the WWW content and its infrast…

Characteristics of Intrapreneurs in Scale-Intensive Service Firms

2014

This empirical paper explores the work of employees in charge of service innovation when firms develop and launch new scale-intensive services by addressing two research questions: i) How do employees responsible for service innovation work? and ii) what are the related managerial implications when developing and launching new scale-intensive services? To this end, 21 qualitative, in-depth interviews were conducted with employees in five large scale-intensive service firms. The findings suggest that the involvement of internal professionals is an asset when new scale-intensive services are developed, and that internal professionals act as intrapreneurs when they are involved in the developm…

“I Am Your Fan; Bookmarked!” Members’ Identification Development in Founder-Led Online Communities

2019

In this study, we present the findings from an inductive and interpretive case study of a founder-led online community (OC), exploring how members’ identification develops within the community over time. Using a longitudinal study of an OC that was founded by a reputable individual, it is shown that members were first attracted to the OC through their affective and cognitive identification with the founder; however, over time, they developed identification through social interaction with other members. The findings show that this transformation was enabled by the founder’s communication behavior, which not only led to inspired and engaged members but also to the emergence of new leaders who…

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…

Sharing on web 3D models of ancient theatres. A methodological workflow

2016

Abstract. In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn’t exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describ…
