The encoding of letter position is a key aspect in all recently proposed models of visual-word recognition. We analyzed the impact of lexical frequency on letter position assignment by examining the temporal dynamics of lexical activation induced by pseudowords extracted from words of different frequencies. For each word (e.g., BRIDGE), we created two pseudowords: A transposed-letter (TL: BRIGD...

Collocations constitute an important type of syntagmatic information whose introduction into WordNets has not yet been addressed. The goal of our work is the integration of the collocational material for the field of emotion nouns encoded in the DIccionario de colocaciones del español (DICE) in terms of Lexical Functions into the Spanish part of the EuroWordNet (SpEWN). Two features of collocat...

In this paper we study a class of numerical methods to solve a singularly perturbed two-point boundary value problem. Our schemes arise as result of choosing an appropriate basis for the solution, as well as making use of collocation. It is possible to obtain arbitrarily high-order methods. We note that, in some cases (constant coefficients), we obtain the exact solution. Particular attention i...

The paper presents a novel approach to extracting dependency information in morphologically rich languages using co-occurrence statistics based not only on lexical forms (as in previously described collocation-based methods), but also on morphosyntactic and wordnet-derived semantic properties of words. Statistics generated from a corpus annotated only at the morphosyntactic level are used as fe...

Although the semantic analysis and the grammatical distribution are treated as separate issues in linguistic theories, there is a close interconnection between the two in that the differences in the lexical meanings are often realized at the levels both of the grammatical function and of the lexical collocation. This is the basic assumption utilized when we design and develop Knowledge Base of ...

Genuine lexical writing assistants that attempt to detect lexical errors such as miscollocations are traditionally less common in Computer Assisted Language Learning than spell and grammar checkers. However, there is empirical evidence of the importance of capturing and correcting miscollocations in the writings of language learners, and therefore an increasing number of proposals deals with th...

The notion of expectancy grammar as a key to understanding the nature of psychologically real processes that underlie language use is introduced by Oller (1979). A central issue in this notion is that expectancy generating systems are constructed and modified in the course of language acquisition. Thus, one of the characteristics of language proficiency is that it consists of such an expectancy...

Extensive knowledge of collocations is a key factor that distinguishes learners from fluent native speakers. Such knowledge is difficult to acquire simply because there is so much of it. This paper describes a system that exploits the facilities offered by digital libraries to provide a rich collocation-learning environment. The design is based on three processes that have been identified as le...
