Concept neighbourhoods in knowledge organisation systems. (2010)
Conference Proceeding
Priss, U., & Old, L. J. (2010). Concept neighbourhoods in knowledge organisation systems. In C. Gnoli, & F. Mazzocchi (Eds.), Paradigms and conceptual systems in knowledge organizationThis paper discusses the application of concept neighbourhoods (in the sense of Formal Concept Analysis) to Knowledge Organisation Systems. Examples are provided using Roget’s Thesaurus, WordNet and Wikipedia categories
Concept Neighbourhoods in Lexical Databases (2010)
Conference Proceeding
Priss, U., & Old, L. J. (2010). Concept Neighbourhoods in Lexical Databases. In L. Kwuida, & B. Sertkaya (Eds.), Formal Concept Analysis (283-295). https://doi.org/10.1007/978-3-642-11928-6_20This paper discusses results from an experimental study of concept neighbourhoods in WordNet and Roget’s Thesaurus. The general aim of this research is to determine ways in which neighbourhood lattices can be derived in real time from a lexical data... Read More about Concept Neighbourhoods in Lexical Databases.
The semantic structure of Roget’s Thesaurus cross-references. (2009)
Conference Proceeding
Old, L. J. (2009). The semantic structure of Roget’s Thesaurus cross-references. In U. Priss, & G. Angelova (Eds.), Conceptual Structures for Extracting Natural Language SemanticsThis study analyzed a database version of Roget’s Thesaurus (Roget’s International Thesaurus, 3rd Edition, 1962) for connectivity patterns among cross-references in order to identify the implicit conceptual structure. Semantic patterns implicit in th... Read More about The semantic structure of Roget’s Thesaurus cross-references..
The FcaFlint software for relation algebra operations on FCA contexts. (2009)
Conference Proceeding
Priss, U. (2009). The FcaFlint software for relation algebra operations on FCA contexts. In Conceptual Structures Tool Interoperability Workshop (13-23)FcaFlint is a tool that implements context operations for FCA formal contexts. It is part of the FcaStone package. This paper provides an introduction to Relation Algebra operations as used by FcaFlint and discusses the commandline interface and i...

Relation algebra operations on formal contexts (2009)
Conference Proceeding
Priss, U. (2009). Relation algebra operations on formal contexts. In S. Rudolph, F. Dau, & S. O. Kutznetsov (Eds.), Conceptual Structures: Leveraging Semantic Technologies (257-269). https://doi.org/10.1007/978-3-642-03079-6_20This paper discusses the use of relation algebra operations on formal contexts. These operations are a generalisation of some of the context operations that are described in the standard FCA textbook (Ganter & Wille, 1999). This paper extends previou...

Revisiting the potentialities of a mechanical thesaurus. (2009)
Conference Proceeding
Priss, U., & Old, L. J. (2009). Revisiting the potentialities of a mechanical thesaurus. In R. Ferre (Ed.), Proceedings of the 7th International Conference on Formal Concept Analysis, ICFCA (284-298). https://doi.org/10.1007/978-3-642-01815-2_21This paper revisits the lattice-based thesaurus models which Margaret Masterman used for machine translation in the 1950’s and 60’s. Masterman’s notions are mapped onto modern, Formal Concept Analysis (FCA) terminology and three of her thesaurus algo... Read More about Revisiting the potentialities of a mechanical thesaurus..
FCA interpretation of relation algebra. (2006)
Conference Proceeding
Priss, U. (2006). FCA interpretation of relation algebra. . https://doi.org/10.1007/11671404_17This paper discusses an interpretation of relation algebra and fork algebra with respect to FCA contexts. In this case, "relation algebra" refers to the DeMorgan-Peirce-Schroeder-Tarski algebra and not to the "relational algebra" as described by Codd...

Conceptual exploration of semantic mirrors. (2005)
Conference Proceeding
Priss, U., & Old, L. J. (2005). Conceptual exploration of semantic mirrors.The "Semantic Mirrors Method" (Dyvik, 1998) is a means for automatic derivation of thesaurus entries from a word-aligned parallel corpus. The method is based on the construction of lattices of linguistic features. This paper models the Semantic Mirro... Read More about Conceptual exploration of semantic mirrors..
Formalizing botanical taxonomies. (2003)
Conference Proceeding
Priss, U. (2003). Formalizing botanical taxonomies. . https://doi.org/10.1007/b11835Because botanical taxonomies are prototypical classifications it would seem that it should be easy to formalize them as concept lattices or type hierarchies. On closer inspection, however, one discovers that such a formalization is quite challenging... Read More about Formalizing botanical taxonomies..
