Normally, the tense and aspect systems of natural languages do not coincide and the correct translation of the tense forms needs a semantic analysis of the text or sentence which uses these forms. The problem with semantic representations is that, often, ambiguities cannot be resolved, though a remarkable effort of inferencing has been invested to the effect that the analysis of the source text...

This study examined the acquisition of prenominal and postnominal genitives by Iranian EFL learners. Two variables were considered: possessive categories and language proficiency. We considered the influence of possessive categories such as lexical modifier, semantic relationship, and weight and syntactic complexity on genitive alternations by Iranian EFL learners. Also, we examined whether the...

Under a lexicalist approach to semantics, a verb completely encodes its syntactic and semantic structures, along with the relevant syntax-tosemantics mapping; polysemy is typically attributed to the existence of different lexical entries. A lexicon organized in this fashion contains much redundant information and is unable to capture cross-categorial morphological derivations. The solution is t...

Current lexical semantic theories provide representations at a coarse grained level. In this paper, I will provide motivations for a fine grained representation for verbs and. nouns. An initial case study is done to serve as evidence that a more detailed representation is needed for tasks that require high accuracy rates, such as machine translation. An automatic approach to gather fine grained...

Since their inception, distributional models of semantics have been criticized as inadequate cognitive theories of human semantic learning and representation. A principal challenge is that the representations derived by distributional models are purely symbolic and are not grounded in perception and action; this challenge has led many to favor feature-based models of semantic representation. We...

In this paper we consider the nature and extent of lexical operations, arguing for a declarative and eomputat ional ly tractable definition of a lexical rule as a component of a unification-based lexicon employing (default) inheritance and typed feature structures. We claim that this notion of lexical rule is capable of capturing the linguistic element of derivational morphological processes as...
