Problems solved by technology

However, the existing research on geographic object ontology has not gone deep into the construction of geographic object ontology for disaster events, and the lack of scientific, efficient, and reasonable ontology construction methods has played a restrictive role in the development of this field.

Embodiment Construction

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings .

[0036] (1) General construction method of geographic object ontology

[0037] 1) Determine the scope of the geographic object ontology

[0038] The geographic object ontology is aimed at the field of spatial information, and mainly studies the entire geographic space. The purpose of creating a geographic object ontology is to build a consensus conceptual model of spatial information in this field, through which a common understanding of spatial information between people and between departments can be achieved, and provide a basis for the sharing and interoperability of spatial information. Consistency in se...

Abstract

The invention provides a method for constructing a geographic object ontology oriented to a disaster event. The method comprises the following steps of: 1) facing the geographic disaster event, determining a relevant concept for defining the geographic object ontology, a composition and a construction rule of a geographic object; 2) conceptualizing space information, and extracting semanteme fromthe space information; 3) determining a correlation between the geographic object and a geographic spatial domain; 4) constructing a logic model of the geographic object ontology according to the concept of the geographic object, the relation and the axiom; 5) encoding and formally expressing the ontology so as to construct the geographic object ontology oriented to a disaster event index; and 6)constructing a geographic object ontology example, and inspecting the correctness of the ontology structural model. The constructed geographic object ontology oriented to the disaster event is the basis of an indexing and analyzing tool, and has technical and application value for handling sudden emergency disaster events, preventing and reducing disasters, improving assistant decisions of government departments and promoting deep and popular application of the geographic space information.

Description

technical field [0001] The invention relates to the field of geospatial information systems, and more specifically, to a method for constructing a disaster event-oriented geographic object ontology. Background technique [0002] Ontology was originally a philosophical concept concerned with the abstract nature of objective reality. Neches, Fikes et al. (1991) gave the definition of ontology first, and Gruber, Borst et al. studied ontology respectively. Most scholars believe that "ontology is a clear and formal specification of a shared conceptual model", which contains four meanings: conceptual model, explicit, formalized, and shared. The development and application of ontology in the field of geospatial information forms geographic ontology, and the research on the latter has been paid attention to in the middle and late 1990s. At present, many research institutions and scholars at home and abroad have paid attention to the study of geographical ontology. [0003] Geogra...
