Opis:
We formulate a certain subtheory of Ishimoto’s [1] quantifier-free fragment of Leśniewski’s ontology, and show that Ishimoto’s theory can be reconstructed in it. Using an epimorphism theorem we prove that our theory is complete with respect to a suitable set-theoretic interpretation. Furthermore, we introduce the name constant 1 (which corresponds to the universal name ‘object’) and we prove its adequacy with respect to the set-theoretic interpretation (again using an epimorphism theorem). Ishimoto’s theory enriched by the constant 1 is also reconstructed in our formalism with into which 1 has been introduced. Finally we examine for both our theories their quantifier extensions and their connections with Leśniewski’s classical quantified ontology.

Opis:
This paper is a discussion of the theoretical conceptualization of past landscapes and the limitations of archaeology in providing objectivistic interpretations. Analyzing a case study of the Dewil Valley landscape I will argue that the sciences about the past emerged based on the “Western” research paradigm. Therefore, local ontologies are often overlooked in archaeological narratives. In this article, I will present the ontologies of the indigenous Tagbanua people, contemporary beliefs related to the landscape, and theoretical approaches presented by researchers. I will argue that ontology can be complex and ambivalent, and that archaeological sources do not always indicate these dynamics.

Opis:
Ontology is the subject of research in various fields of science, including humanities and economics. At present, ontologies are the subject of research in various research facilities, among others, engineering systems, knowledge engineering and knowledge management theory. The most important aspect from the point of view of this article is the aspect of knowledge management. The first definition created for the purpose of computing is the definition of T. Gruber in 1993. It was used in the field of artificial intelligence in order to facilitate the sharing and reuse of stored knowledge. This article attempts to present some concepts of the ontology. The selected ontology definitions created by T. Gruber, A. Bassara and A. Maedche. The principles and process of creating ontologies. The last part presents selected ontology description languages such as Resource Description Framework (RDF) and Web Ontology Language (OWL).

Collaborative design of a synchrotron ontology
Autorzy:
Szota-Pachowicz, Julia
Wydawca:
Springer
Opis:
The paper presents an approach to collaborative analysis and design of the synchrotron ontology. The ontology building process requires the analysis of the subject of conceptualization, the definition of goals and tasks that ontology is to fulfill as well as the way of implementation of an ontology in the appropriate logic language. It often needs cooperation of many specialists: domain experts, analysts and engineers who implement the ontology. In this paper, the use of competency questions defined in cooperation with many specialists from different domains and usage of use cases to develop the synchrotron ontology, is presented. The competency questions are used to define the subject of conceptualization to be represented by the ontology, while collaborative analysis of requirements facilitates specification of use cases and implementation phases. The presented approach enables the cooperation of many engineers in defining ontology design patterns that could be reused in many domains. It is applied to build a prototype high level ontology that could be used to develop ontologies for specific synchrotrons.

Opis:
Nowadays, with growing use of location-aware, wirelessly connected, mobile devices, we can easily capture trajectories of mobile objects. To exploit these raw trajectories, we need to enhance them with semantic information. Several research fields are currently focusing on semantic trajectories to support inferences and queries to help users validate and discover more knowledge about mobile objects. The inference mechanism is needed for queries on semantic trajectories connected to other sources of information. Time and space knowledge are fundamental sources of information used by the inference operation on semantic trajectories. This article discusses new approach for inference mechanisms on semantic trajectories. The proposed solution is based on an ontological approach for modelling semantic trajectories integrating time concepts and rules. We present a case study with experiments, optimization and evaluation to show the complexity of inference and queries. Then, we introduce a refinement algorithm based on temporal neighbour to enhance temporal inference. The results show the positive impact of our propos al on reducing the complexity of the inference mechanism.

The importance of cross-lingual information for matching Wikipedia with the Cyc ontology
Autorzy:
Wróbel, Krzysztof
Smywiński-Pohl, Aleksander
Wydawca:
Technical University of Aachen
Opis:
In this paper we try to answer the question how cross-lingual evidence may improve matching between different classification schemas. We concentrate specifcally on the task of mapping between Wikipedia categories and Cycterms as well as the classication of Wikipedia articles to the Cyctaxonomy and show how this process may be improved by consuming the evidence that is available in different editions of Wikipedia. The results show that the performance of the mapping procedure may be improved from 0.6 to 4.9 percentage points, depending on the number of external Wikipedia editions and the given task.

Opis:
Automatic communication can help reduce errors in communication between navigators, and, consequently, increase the level of navigation safety. This article reviews some methods for the development of an ontology and looks into processes for communication at sea. Three basic elements of ontology can be distinguished: navigational information, communication and interface. The possibility of applying these methods for the construction of ontology was analyzed for a system of automatic communication at sea.
