TL;DR: This paper relates domain analysis and ontologies, illustrates a step in the domain analysis method for identifying and categorizing concepts, and describes how this step, borrowed from library science, is incorporated into thedomain analysis method.
Abstract: An ontology can be defined as a conceptualization of a domain or subject area typically captured in an abstract model of how people think about things in the domain. Humans have been producing ontologies for millennia to understand and explain our rationale and environment. Only recently has the process of building ontologies become a research topic of interest. Today, ontologies are built very much ad-hoc. A terminology is first developed providing a controlled vocabulary for the subject area or domain of interest, then it is organized into a taxonomy where key concepts are identified, and finally these concepts are defined and related to create an ontology. This paper describes how a domain analysis method based on faceted classification can be used for building ontologies. It relates domain analysis and ontologies, illustrates a step in the domain analysis method for identifying and categorizing concepts, and describes how this step, borrowed from library science, is incorporated into the domain analysis method. The paper also gives an overview of the method and describes a tool for automating parts of the process.

...The faceted approach, proposed by Ranganathan in 1939 [ 13 ], relies not on the breakdown of a universe of knowledge, but on building up or synthesizing from the subject statements of particular documents....

TL;DR: The philosophy and function of BC2 are described, as is the process of building a knowledge structure on facet analytical principles, with emphasis on the problems of complex subject description and retrieval and multidimensionality.
Abstract: The library classification scheme was the first means of subject access to information, but is largely disregarded as a tool for the management of electronic resources; modern classifications built on facet analytical principles are more appropriate to this purpose than is generally realised. Faceted classifications as exemplified by the Bliss Bibliographic Classification (BC2) are powerful tools for the management of vocabulary, characterised by a rigorous analytical approach to terms, and the clear identification of semantic and syntactic relationships and structures. The philosophy and function of BC2 are described, as is the process of building a knowledge structure on facet analytical principles. The range of related functions of such structures when employed as knowledge management tools (as classification, thesaurus, subject heading list, browsable index) is considered, as is the potential of facet analytical knowledge structures for the management of digital materials. Facet analysis is regarded as a powerful methodology for the creation of structures appropriate to specific retrieval requirements in a range of contexts, with emphasis on the problems of complex subject description and retrieval and multidimensionality.

TL;DR: It is claimed that for domain analysis to work cumulatively transferable definitions of domains must be written, and the author provides two axes to consider: Areas of Modulation and Degrees of Specialization.
Abstract: This paper adds two analytical devices to domain analysis, claiming that for domain analysis to work cumulatively transferable definitions of domains must be written. To establish this definition the author provides two axes to consider: Areas of Modulation and Degrees of Specialization. These axes may serve as analytical devices for the domain analyst to delineate what is being studied and what is not being studied in a domain analysis.

TL;DR: Faceted lightweight ontologies have a well defined structure and, as such, they are easier to create, to share among users, and they also provide more organized input to semantics based applications, such as semantic search and navigation.
Abstract: We concentrate on the use of ontologies for the categorization of objects, e.g., photos, books, web pages. Lightweight ontologies are ontologies with a tree structure where each node is associated a natural language label. Faceted lightweight ontologies are lightweight ontologies where the labels of nodes are organized according to certain predefined patterns which capture different aspects of meaning, i.e., facets . We introduce facets based on the Analytico-Synthetic approach, a well established methodology from Library Science which has been successfully used for decades for the classification of books. Faceted lightweight ontologies have a well defined structure and, as such, they are easier to create, to share among users, and they also provide more organized input to semantics based applications, such as semantic search and navigation.

TL;DR: GeoWordNet is a semantic resource created from the full integration of GeoNames, other high quality resources and WordNet, achieving a never reached before accuracy level and a very satisfactory quantitative result, both in terms of concepts and geographical entities.
Abstract: Geo-spatial ontologies provide knowledge about places in the world and spatial relations between them. They are fundamental in order to build semantic information retrieval systems and to achieve semantic interoperability in geo-spatial applications. In this paper we present GeoWordNet, a semantic resource we created from the full integration of GeoNames, other high quality resources and WordNet. The methodology we followed was largely automatic, with manual checks when needed. This allowed us accomplishing at the same time a never reached before accuracy level and a very satisfactory quantitative result, both in terms of concepts and geographical entities.
