Design of Geo-ontology Based on Concept Lattice
نویسندگان
چکیده
Ontology is an explicit specification of a conceptualization in Artificial Intelligence. Geo-ontology is a very complex and intricate concept. Lots of researchers begin to research Geo-ontology, but many of them just transplant ontology concept of information science into GIS. Based on existed expert’s knowledge, starting from the basic components, we determine the scope of Geoontology at first. And then analysing the ontology property of each geographical concept, we use concept lattice to build the relationship among geographical concepts after confirming the scope of Geo-ontology. Completing the collection of concepts’ meaning, attribute, picture and instance, we design a prototype system of Geo-ontology using VC6++ and SQL Server at last. * Corresponding author.

An Entropy-Based Weighted Concept Lattice for Merging Multi-Source Geo-Ontologies
To deal with the complexities associated with the rapid growth in a merged concept lattice, a formal method based on an entropy-based weighted concept lattice (EWCL) is proposed as a mechanism for merging multi-source geographic ontologies (geo-ontologies). First, formal concept analysis (FCA) is used to formalize different term-based representations in relation to the geographic domain, and to...
متن کاملA Concept Lattice for Semantic Integration of Geo-Ontologies Based on Weight of Inclusion Degree Importance and Information Entropy
Constructing a merged concept lattice with formal concept analysis (FCA) is an important research direction in the field of integrating multi-source geo-ontologies. Extracting essential geographical properties and reducing the concept lattice are two key points of previous research. A formal integration method is proposed to address the challenges in these two areas. We first extract essential ...
متن کاملA Semi-automatic Method to Ontology Design by Using FCA
Ontology design is a complex and time-consuming process. It is extremely difficult for human experts to discover ontology from given data or texts. This paper presents a semi-automatic method for ontology extraction and design. The method is based on Formal Concept Analysis and a Horn clause model of a concept lattice. Inputs to the technique are domain-specific texts or data. After transformat...

متن کاملThe Research and Practice of Geo-ontology Construction
From the perspective of spatial information sharing and interoperation, the concept of geo-ontology has been proposed in this paper. At first, a brief introduction to the Geo-Ontology concept has been described and the hierarchical structure of geo-ontology has also been analyzed. Then, the traditional method of ontology construction has been discussed and the existing problems have also been s...
