Automatic Induction of Lexical Inheritance Hierarchies

by Harald Lüngen, Caroline Sporleder - Proceedings of 11th Annual Meeting of GLDV: Multilinguale Corpora. Codierung, Strukturierung, Analyse , 1999
"... this paper, we introduce our lexicon of German morphemes used in a corpus analysis task and give an overview of how a lexical hierarchy of morph types was manually constructed. We then present an algorithm called Top-Down Attribute Selection for machine learning of single lexical inheritance hierarc ..."

Lexical Inheritance in Upper-Level Ontologies

by Pablo Gamallo , 2000
"... Most of lexical bases and computational ontologies are organized by means of a lexical inheritance system based upon the IS-A taxonomic relation. This relation is conceived of as an ontological channel allowing the transfer of lexical information to a great extent. We will assume, however, that ..."

"... Abstract Lexical inheritance hierarchies are used widely as a means of representing lexical informationefficiently by capturing generalisations. But so far there have been few attempts to construct them automatically. This paper presents a two-step construction algorithm in which a Galois lattice is ..."

A Galois Lattice based Approach to Lexical Inheritance Hierarchy Learning

by Caroline Sporleder - In 15th European Conference on Artificial Intelligence (ECAI’02): Workshop on Machine Learning and Natural Language Processing for Ontology Engineering , 2002

This paper presents a two-step construction algorithm in which a Galois lattice is built and then pruned into an inhe ..."

Semantic similarity based on corpus statistics and lexical taxonomy

by Jay J. Jiang, David W. Conrath - Proc of 10th International Conference on Research in Computational Linguistics, ROCLING’97 , 1997
"... This paper presents a new approach for measuring semantic similarity/distance between words and concepts. It combines a lexical taxonomy structure with corpus statistical information so that the semantic distance between nodes in the semantic space constructed by the taxonomy can be better quantifie ..."

The Generative Lexicon

by James Pustejovsky - Computational Linguistics , 1991
"... this paper, I will discuss four major topics relating to current research in lexical semantics: methodology, descriptive coverage, adequacy of the representation, and the computational usefulness of representations. In addressing these issues, I will discuss what I think are some of the central prob ..."

into the larger lexical knowledge base through a theory of lexical inheritance. This provides us with the necessary principles of global organization for the lexicon, enabling us to fully integrate our natural language lexicon into a conceptual whole

SELF: The power of simplicity

by David Ungar, Randall B. Smith , 1991
"... SELF is an object-oriented language for exploratory programming based on a small number of simple and concrete ideas: prototypes, slots, and behavior. Prototypes combine inheritance and instantiation to provide a framework that is simpler and more flexible than most object-oriented languages. Slots ..."
Abstract - Cited by 640 (19 self) - Add to MetaCart
. Slots unite variables and procedures into a single construct. This permits the inheritance hierarchy to take over the function of lexical scoping in conventional languages. Finally, because SELF does not distinguish state from behavior, it narrows the gaps between ordinary objects, procedures

Axiomathes DOI 10.1007/s10516-011-9152-1 ORIGINAL PAPER Lexical Inheritance with Meronymic Relationships

by Pablo Gamallo , 2010
"... Abstract In most computational ontologies, information inheritance is based on the taxonomic relation is_a. A given type inherits from other type only if the latter subsumes the former. We assume, however, that inheritance can be related, not only to the taxonomic relation, but also to the meronymic ..."

Discovering Lexical Generalisations.

by Supervised Machine Learning, Caroline Sporleder , 2004
"... Grammar development over the last decades has seen a shift away from large inventories of grammar rules to richer lexical structures. Many modern grammar theories are highly lexicalised. But simply listing lexical entries typically results in an undesirable amount of redundancy. Lexical inheritance ..."
