E-recruitment uses a range of web-based technologies to find, evaluate, and hire new personnel for organizations. A crucial challenge in this arena lies in the categorization of job offers: candidates and operators often explore and analyze large numbers of offers and profiles through a set of job categories. To date, ...

In the last decades, many measures and metrics have been proposed with the goal of automatically providing quantitative rather than qualitative indications over researchers' academic productions. However, when evaluating a researcher, most of the commonly-applied measures do not consider one of the key aspect of every research work: the collaborations ...

Social networks and microblogging systems play a fundamental role in the diffusion of information. The information, from different sources, reaches each user through multiple connections, the study of which is indispensable for the sake of understanding the dynamics of its evolution and expansion. In this paper, we propose a system ...

Taxonomies embody formalized knowledge and define aggregations between concepts/categories in a given domain, facilitating the organization of the data and making the contents easily accessible to the users. Since taxonomies have significant roles in data annotation, search and navigation, they are often carefully engineered. However, especially in domains, such as ...

In this paper we present a novel ontology-based model for the representation of the dramatic features of narrative media (video, text, audio, etc.), focused on the notions of the character's motivated actions. We describe the theoretical background, composed of narratological theories and rational agent theories, that support the proposed ontological ...

Most of the existing document and web search engines rely on keyword-based queries. To find matches, these queries are processed using retrieval algorithms that rely on word frequencies, topic recentness, document authority, and (in some cases) available ontologies. In this paper, we propose an innovative approach to exploring text collections ...
