TL;DR: This paper proposes methods for guiding users in the localization of ontologies, and provides tools for supporting the process, and describes a tool built according to the guidelines proposed for an automatic localization ofontologies.
Abstract: International organizations (e.g., FAO, WHO, etc.) are increasingly expressing the need for multilingual ontologies for different purposes, e.g., ontology-based multilingual machine translation, multilingual information retrieval. However, most of the ontologies built so far have mainly English or another natural language as basis. Since multilingual ontology building is a very expensive and time-consuming undertaking, we propose methods for guiding users in the localization of ontologies, and provide tools for supporting the process. The main contributions of this paper are: i) the description of a generic Ontology Localization Activity and a methodology for guiding in the localization of ontologies; ii) the description of a tool built according to the guidelines proposed for an automatic localization of ontologies; and iii) a set of experiments used to evaluate the methodological and technological aspects of the Ontology Localization Activity.

TL;DR: This paper explains the concept of ontologies as a tool for data integration and briefly describes a method for constructing an ontology by using a hybrid ontology approach.
Abstract: The term Federated Databases refers to the data integration of distributed, autonomous and heterogeneous databases. However, a federation can also include information systems, not only databases. At integrating data, several issues must be addressed. Here, we focus on the problem of heterogeneity, more specifically on semantic heterogeneity that is, problems rela ted to semantically equivalent concepts or semantically related/unrelated concepts. In order to address this problem, we apply the idea of ontologies as a tool for data integration. In this paper, we explain this concept and we briefly describe a method for constructing an ontology by using a hybrid ontology approach.

TL;DR: A set of ontologies that complement CORA with notions such as industrial design and positioning are introduced and updates to CORA are introduced in order to provide more ontologically sound representations of autonomy and of robot parts.
Abstract: The working group Ontologies for Robotics and Automation, sponsored by the IEEE Robotics & Automation Society, recently proposed a Core Ontology for Robotics and Automation (CORA). This ontology was developed to provide an unambiguous definition of core notions of robotics and related topics. It is based on SUMO, a top-level ontology of general concepts, and on ISO 8373:2012 standard, developed by the ISO/TC184/SC2 Working Group, which defines-in natural language-important terms in the domain of Robotics and Automation (R&A). In this paper, we introduce a set of ontologies that complement CORA with notions such as industrial design and positioning. We also introduce updates to CORA in order to provide more ontologically sound representations of autonomy and of robot parts. HighlightsWe discuss extensions to a core ontology for the robotics and automation field.The ontology aims to specify the main notions across robotics subdomains.We define robot, robotic system, robotic environment, and related notions.We discuss concepts regarding the notion of design, in industrial contexts.We discuss notions regarding the modes of operation of a robot.We discuss notions regarding the position, orientation and pose of a robot.

TL;DR: In this paper, the authors propose an ontology of technology that will be both acceptable to ontology's critics and useful for those engaged with technology, by drawing upon recent developments in social ontology and extending these into the technological realm.
Abstract: Ontology tends to be held in deep suspicion by many currently engaged in the study of technology. The aim of this paper is to suggest an ontology of technology that will be both acceptable to ontology’s critics and useful for those engaged with technology. By drawing upon recent developments in social ontology and extending these into the technological realm it is possible to sustain a conception of technology that is not only irreducibly social but able to give due weight to those features that distinguish technical objects from other artefacts. These distinctions, however, require talk of different kinds of causal powers and different types of activity aimed at harnessing such powers. Such discussions are largely absent in recent technological debates, but turn out to be significant both for ongoing technology research and for the recasting of some more traditional debates within the philosophy of technology

TL;DR: An off-context study of eight semantic measures based on an ontology restricted to subsomption links is presented and a comparative study based on a set of semantic and theoretical criteria is proposed.
Abstract: Ontologies are in the heart of the knowledge management process. Different semantic measures have been proposed in the literature to evaluate the strength of the semantic link between two concepts or two groups of concepts from either two different ontologies (ontology alignment) or the same ontology. This article presents an off-context study of eight semantic measures based on an ontology restricted to subsomption links. We first present some common principles, and then propose a comparative study based on a set of semantic and theoretical criteria.
