This paper will focus on the semantic representation of verbs in computer systems and its impact on lexical selection problems in machine translation (MT). Two groups of English and Chinese verbs are examined to show that lexical selection must be based on interpretation of the sentence as well as selection restrictions placed on the verb arguments. A novel representation scheme is suggested, a...

In this paper we present a self-organizing neural network model of early lexical development called DevLex. The network consists of two self-organizing maps (a growing semantic map and a growing phonological map) that are connected via associative links trained by Hebbian learning. The model captures a number of important phenomena that occur in early lexical acquisition by children, as it allo...

This article presents the semantic layer of Walenty—a new valence dictionary of Polish predicates, with a number of novel features, as compared to other such dictionaries. The dictionary contains two layers, syntactic and semantic. The syntactic layer describes syntactic and morphosyntactic constraints predicates put on their dependants. In particular, it includes a comprehensive and powerful p...

An interactive 2-step theory of lexical retrieval was applied to the picture-naming error patterns of aphasic and nonaphasic speakers. The theory uses spreading activation in a lexical network to accomplish the mapping between the conceptual representation of an object and the phonological form of the word naming the object. A model developed from the theory was parameterized to fit normal erro...

We propose a method to derive predictions for single-word retrieval times from a semantic space model trained on text corpora. In Experiment 1 we present a large corpus analysis demonstrating that it is the number of unique semantic contexts a word appears in across language, rather than simply the number of contexts or the frequency of the word, that is the most salient predictor of lexical de...

The role and nature of syntactic categories in language acquisition is unresolved. While many researchers assume that children have innate knowledge about syntactic categories which helps them to acquire syntax, others assume that children’s early syntactic theories are semantically based and learned. In this paper I will summarize evidence against both a syntactic and a semantic basis for chil...

we present the basic results on the representation theory of the alternating groups. our approach is based on clifford theory.

Current research being undertaken at both Cambridge and IBM is aimed at the construction of substantial lexicons containing lexical semantic information capable of use in automated natural language processing (NLP) applications. This work extends previous research on the semi-automatic extraction of lexical information from machine-readable versions of conventional dictionaries (MRDs) (see e.g....
