This paper addresses a specific case of the task of lexical acquisition understood as the induction of information about the linguistic characteristics of lexical items on the basis of information gathered from their occurrences in texts. Most of the recent works in the area of lexical acquisition have used methods that take as much textual data as possible as source of evidence, but their perf...

Unknown lexical items present a major obstacle to the development of broadcoverage semantic role labeling systems. We address this problem with a semisupervised learning approach which acquires training instances for unseen verbs from an unlabeled corpus. Our method relies on the hypothesis that unknown lexical items will be structurally and semantically similar to known items for which annotat...

A number of attitudinal expressions are identified and analyzed using dependency based syntactic analysis. A claim is made that attitudinal loading of lexical items is dynamic rather than lexical and that attitudinal loading of individual lexical items is acquired through their use in attitudinally loaded structures.

Two studies examined the role of phonological cues in the lexical categorization of new words when children could also rely on learning by exclusion and whether the role of phonology depends on extensive experience with a language. Phonological cues were assessed via phonological typicality - an aggregate measure of the relationship between the phonology of a word and the phonology of words in ...

Here a study is conducted to examine orthographic effects on initial phoneme addition and deletion tasks with an adult population. The results of a previous study [1] with children suggest that the use of an orthographic strategy depends on lexical status, so two experiments were conducted, one with real words and the other with nonwords. In both experiments, some items were amenable to both an...

When using hierarchical formalisms for lexical information, the need arises to insert (i.e. classify) lexical items into these hierarchies. This includes at least the following two situations: (1) testing generalizations when designing a lexical hierarchy; (2) transferring large numbers of lexical items from raw data files to a finished lexical hierarchy when using it to build a large lexicon. ...

This paper argues that the word order possibilities of a language are partly determined by the parts-of-speech system of that language. In languages in which lexical items are specialized for certain functionally defined syntactic slots (e.g. the modifier slot within a noun phrase), the identifiability of these slots is ensured by the nature of the lexical items (e.g. adjectives) themselves. As...

How do children acquire the meaning of words? And why are words like know harder for learners to acquire than words like dog or jump? We suggest that a considerable part of the difficulty of acquiring the vocabulary of natural languages consists not in overcoming conceptual difficulties with abstract word meanings but rather in mapping these meanings onto their corresponding lexical forms. We s...
