Ontology evaluation has been recognized for a long time now as an important part of the ontology development lifecycle, and several methods, processes and metrics have been developed for that purpose. Nevertheless, vagueness is a quality dimension that has been neglected from most current approaches. Vagueness is a common human knowledge and linguistic phenomenon, typically manifested by terms and concepts that lack clear applicability conditions and boundaries such as high, expert, bad, near etc. As such, the existence of vague terminology in an ontology may hamper the latter's quality, primarily in terms of shareability and meaning explicitness. With that in mind, in this short paper we argue for the need of including vagueness in the ontology evaluation activity and propose a set of metrics to be used towards that goal. © 2014 Springer International Publishing.

The emergence in recent years of initiatives like the Linked Open Data (LOD) has led to a significant increase in the amount of structured semantic data on the Web. In this paper we argue that the shareability and wider reuse of such data can very often be hampered by the existence of vagueness within it, as this makes the data's meaning less explicit. Moreover, as a way to reduce this problem, we propose a vagueness metaontology that may represent in an explicit way the nature and characteristics of vague elements within semantic data.

The Universal Plug and Play (UPnP) protocol lets users share multimedia content across devices and display it in multimedia renderers in home-based LANs. However, UPnP doesn't support sharing this content between homes (for example, with friends, relatives, or workmates), and content can be difficult to find. A UPnP extension provides uniform access to multimedia content belonging to different homes, such as content from a user's Facebook friends. In addition, an extended UPnP control point lets users add semantic annotations to their multimedia resources and link them to the linked data cloud to facilitate their discovery by others. © 2011 IEEE.

Semantic tagging of a textual document involves identifying and assigning to it appropriate entities that best summarize its content, i.e. entities that constitute a representative description of what the document is specifically about. The effective automation of this process requires from the system to be able to distinguish between the entities that play a central role to the documents's meaning and those that are just complementary to it. For example, a news article might make reference to many politicians even when its primary subject is only one of them. To that end, various approaches have utilized ontologies as a means to narrow down the meaning of a document and infer appropriate tags, including a recent contribution of ours regarding a tagging framework that exploits ontological relations. In this work we revise and extend this framework so as to be able to exploit also fuzzy ontological information. Experiments in different domains show that this exploitation manages to improve the effectiveness of the tagging process. © 2012 IEEE.

OGOLOD is a Linked Open Data dataset derived from different biomedical resources by an automated pipeline, using a tailored ontology as a scaffold. The key contribution of OGOLOD is that it links, in new RDF triples, genetic human diseases and orthologous genes, paving the way for a more efficient translational biomedical research exploiting the Linked Open Data cloud. © 2014 - IOS Press and the authors.

Nowadays, especially after the recent financial downturn, companies are looking for much more efficient and creative business processes. They need to place better solutions in the market in a less time with less cost. There is a general intuition that communication and collaboration, especially mixed with Web 2.0 approach within companies and ecosystems, can boost the innovation process with positive impacts on business indicators. Open Innovation within an Enterprise 2.0 context is a one of the most chosen paradigm for improving the innovation processes of enterprises, based on the collaborative creation and development of ideas and products. The key feature of this new paradigm is that the knowledge is exploited in a collaborative way flowing not only among internal sources, i.e. R&D departments, but also among external ones as other employees, customers, partners, etc. In this paper we show how an ontology-based analysis of plain text can provide a semantic contextualization of content support tasks, such as finding semantic distance between contents, and can help in creating relations between people with shared knowledge and interests. Along this paper we will present the results obtained by the adoption of this technology in a large corporate environment like Bankinter, a financial institution, Telefonica I+D, an international telecommunication firm and Repsol, a major oil company in Spain. © 2012 Elsevier Ltd.

Knowledge Tagger performs Named Entity Resolution (NER) in texts using relevant domain ontologies and semantic data as background knowledge. Its distinguishing characteristic is its disambiguation-related customization capabilities as it allows users to define and apply custom disambiguation evidence models, based on their knowledge about the domain(s) and expected content of the texts to be analyzed. In this demo we explain the structure and content of such evidence models and we demonstrate how, given a concrete resolution scenario, one may use our system to define and apply them to texts pertaining to this scenario.

We describe the datos.bne.es library dataset. The dataset makes available the authority and bibliography catalogue from the Biblioteca Nacional de Espana (BNE, National Library of Spain) as Linked Data. The catalogue contains around 7 million authority and bibliographic records. The records in MARC 21 format were transformed to RDF and modelled using IFLA (International Federation of Library Associations) ontologies and other well-established vocabularies such as RDA (Resource Description and Access) or the Dublin Core Metadata Element Set. A tool named MARiMbA automatized the RDF generation process and the data linkage to DBpedia and other library linked data resources such as VIAF (Virtual International Authority File) or GND (Gemeinsame Normdatei, the authority dataset from the German National Library). © 2012 - IOS Press and the authors.
