Representing regularities in the metaphoric lexicon
نویسنده
چکیده
This paper describes a system for representing knowledge about conventional metaphors for use by natural language analysis, generation and acquisition systems. A system of hierarchically related structured associations is used. These associations are implemented as a part of the KODIAK representation language. Particular attention is paid in this paper to representational mechanisms that can capture generalizations over the system of conventional metaphors as a whole.

Understanding New Metaphors
Metaphors are widespread in natural language. Most natural language processing systems have failed to adequately deal with this issue. A two part approach to this problem involving a Metaphoric Lexicon and a dynamic extension system is described. The extension mechanism operates by analogically mapping previously understood mappings to account for new uses based on known regularities in the Eng...
متن کاملRepresenting a System of Lexical Types Using Default Unification
Default inheritance is a useful tool for encoding linguistic generalisations that have exceptions. In this paper we show how the use of an order independent typed default unification operation can provide non-redundant highly structured and concise representation to specify a network of lexical types, that encodes linguistic information about verbal subcategorisation. The system of lexical type...
متن کاملOn the Role of Derivational Processes in the Formation of Non-Taxonomic Classes of Lexical Units in Russian
The paper is focused on classes of lexical units which arise as a result of derivational processes – word formation and semantic transfers, acting either in isolation or together, on the basis of common semantic foundations that bind targets and sources of derivation. The lexical items which constitute the classes under study vary in their denotative characteristics and due to their categ...
متن کاملWord Meanings Evolve to Selectively Preserve Distinctions on Salient Dimensions
Words refer to objects in the world, but this correspondence is not one-to-one: Each word has a range of referents that share features on some dimensions but differ on others. This property of language is called underspecification. Parts of the lexicon have characteristic patterns of underspecification; for example, artifact nouns tend to specify shape, but not color, whereas substance nouns sp...
متن کاملAdversarial Training for Unsupervised Bilingual Lexicon Induction
Word embeddings are well known to capture linguistic regularities of the language on which they are trained. Researchers also observe that these regularities can transfer across languages. However, previous endeavors to connect separate monolingual word embeddings typically require cross-lingual signals as supervision, either in the form of parallel corpus or seed lexicon. In this work, we show...
