Ontologies are conceptualizations of some domain, defining its concepts and their relationships. An interesting question is how do we relate the ontological concepts to the general vocabulary of the domain? In this paper we present the concept of ontological profiles, what they are, how they are constructed, and how they may be used. We propose that the ontological profile is a link between the...

With the rapid development of remote sensing platform and sensor technique, the amount of satellite images has frequently increased. In order to analyze, manage and retrieve spatial information, several techniques are used to improve the quality of retrieval systems and to perform semantic in the retrieval process. In this paper, we propose an ontology-based approach for semantic retrieving of ...

Throughout his work M. Heidegger develops the theme of authentic logic contrasting it with prevailing understanding character, essence and goals academic logic. He pays special attention to ontological justification logic, derivative nature truth, subject-predicate structure judgement, copula derivation rules. also focuses on status logical negation language ofsymbolic examines in detail justif...

Knowledge management systems have often been considered as a means for sharing knowledge among communities of users. The key of success of knowledge sharing in the field of agriculture is using sharing agreed terminologies such as ontological knowledge especially in multilingual aspects. This paper proposes a workbench for collaborative ontological knowledge construction and maintenance with au...

Ontological databases extend traditional databases with ontological constraints. This technology is crucial for many applications such as semantic data publishing and integration as well as model-driven database design. For many classes of ontological constraints, query answering can be solved via query rewriting. In particular, given a conjunctive query and a set of ontological constraints, th...

The increased sensitivity of engineered products to external forces requires new computer-based design tools that can express the richness and complexity of product knowledge. This paper is a progress report of the author’s research towards the development of such a knowledge-based design tool, called the Design Knowledge Specification Language (DKSL). A key goal is to ensure the maximum possib...

In this paper I present a novel objection to ontological arguments. The argument concerns ontological arguments in general and has the general form of a reductio ad absurdum. Roughly, it rests on the fact that if a sound ontological argument were available, it would contradict the very nature of God. For God aims at maximising the development of human good qualities (including thus faith) and i...

This essay aims at showing how the “mass hermit”, as defined by Günther Anders, is the logical point of arrival of that philosophical process which has interpreted human subjectivity as a closed system, intended as the sum of two mechanically overlapped parts: a biological-natural one and a psychological-intellectual one. This figure is counterposed with a subject who is “always already somewhe...

We extend traditional functional dependencies (FDs) for data quality purposes to accommodate ontological variations in the attribute values. We begin by formally defining a novel class of dependencies called ontological FDs, which strictly generalize traditional FDs by allowing differences controlled by an ontology database. The ontology databases contain information about synonyms. We then foc...
