Presentation / Conference Contribution
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.
An application of formal concept analysis to semantic neural decoding. (2009)
Journal Article
Endres, D., Foldiak, P., & Priss, U. (2009). An application of formal concept analysis to semantic neural decoding. Annals of Mathematics and Artificial Intelligence, 57, 233-248. https://doi.org/10.1007/s10472-010-9196-8This paper proposes a novel application of Formal Concept Analysis (FCA) to neural decoding: the semantic relationships between the neural representations of large sets of stimuli are explored using concept lattices. In particular, the effects of neu... Read More about An application of formal concept analysis to semantic neural decoding..

Relation algebra operations on formal contexts (2009)
Presentation / Conference Contribution
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)
Presentation / Conference Contribution
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..
Lattice-based modelling of thesauri. (2008)
Report
Priss, U., & Old, L. J. (2008). Lattice-based modelling of thesauriThis paper revisits ideas about the use of lattices as underlying conceptual structures in information retrieval and machine translation as suggested by researchers in the 1950s and 1960s. It describes how these ideas were originally presented, how... Read More about Lattice-based modelling of thesauri..
Bilingual word association networks. (2007)
Book Chapter
Priss, U., & Old, L. J. (2007). Bilingual word association networks. In U. Priss, S. Polovina, & R. Hill (Eds.), Conceptual Structures: Knowledge Architectures for Smart Applications (310-320). Springer-Verlag. https://doi.org/10.1007/978-3-540-73681-3_23Bilingual word association networks can be beneficial as a tool in foreign language education because they show relationships among cognate words of different languages and correspond to structures in the mental lexicon. This paper discusses possib... Read More about Bilingual word association networks..
FCA interpretation of relation algebra. (2006)
Presentation / Conference Contribution
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...

Linguistic applications of formal concept analysis. (2005)
Book Chapter
Priss, U. (2005). Linguistic applications of formal concept analysis. In B. Ganter, G. Stumme, & R. Wille (Eds.), Formal Concept Analysis, Foundations and Applications (149-160). Springer-Verlag. https://doi.org/10.1007/11528784_8Formal concept analysis as a methodology of data analysis and knowledge representation has potential to be applied to a variety of linguistic problems. First, linguistic applications often involve the identification and analysis of features, such as... Read More about Linguistic applications of formal concept analysis..
Conceptual exploration of semantic mirrors. (2005)
Presentation / Conference Contribution
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..
Modelling lexical databases with formal concept analysis. (2004)
Journal Article
Priss, U., & Old, L. J. (2004). Modelling lexical databases with formal concept analysis. Journal of universal computer science J. UCS, 10, 967-984. https://doi.org/10.3217/jucs-010-08-0967This paper provides guidelines and examples for visualising lexical relations using Formal Concept Analysis. Relations in lexical databases often form trees, imperfect trees or poly-hierarchies which can be embedded into concept lattices. Many-to-man...

Formalizing botanical taxonomies. (2003)
Presentation / Conference Contribution
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..
