Bottom-Up Construction of Ontologies
We present a particular way of building ontologies that proceeds in a bottom-up fashion. Concepts are defined in a way that mirrors the way their instances are composed out of smaller objects. The smaller objects themselves may also be modeled as being composed. Bottom-up ontologies are flexible through the use of implicit and, hence, parsimonious part-whole and subconceptsuperconcept relations...
متن کاملFCA-MERGE: Bottom-Up Merging of Ontologies
Ontologies have been established for knowledge sharing and are widely used as a means for conceptually structuring domains of interest. With the growing usage of ontologies, the problem of overlapping knowledge in a common domain becomes critical. We propose the new method FCA–MERGE for merging ontologies following a bottom-up approach which offers a structural description of the merging proces...
متن کاملBottom-up construction of ontologies: the case of an ontology of pure substances
Bottom-up construction of ontologies departs from the more usual taxonomic approach to ontology development. It allows for parsimonious speci cation of concepts. De ned concepts are written as compact expressions that allow exible reasoning. Obvious applications include chemistry and engineering design. For such domains, the method enables better ontologies than the taxonomic method. Taxonomic ...
متن کاملBottom-Up Ontology Construction with Contento
In this demo paper we show an approach to build Semantic Web ontologies from sample linked data with a tool named Contento. Contento is a data driven ontology construction kit, based on Formal Concept Analysis (FCA). We show the exploration and analysis functionalities of Contento, as well as the method to generate, annotate and prune concept hierarchies. Moreover, we describe a procedure to go...
متن کاملBottom-up Integration of Ontologies in a Database Context
We describe a pragmatic approach to the creation of local ontologies for databases which must be integrated into multi-agent systems. Our approach avoids the introduction of an extra language, solely for modelling the required ontological information, by showing how to extend the expressiveness of a typical OODBMS data deenition language. In this paper, we outline the principle behind our appro...
