This study investigated the impact of semantic clustering on Iranian EFL learners’ vocabulary retention at advanced level. Participants were female learners randomly assigned to two groups of 15. Four instruments (TOEFL test; vocabulary pretest; immediate posttest, and delayed recall posttest) were used. The experimental group underwent semantic clustering vocabulary presentation in which the l...

This study investigated the effect of using visual aids, semantic elaboration, and visual aids plus semantic elaboration on the Iranian EFL learners' vocabulary learning. To conduct the study, the researchers assigned 49 elementary learners to three homogeneous groups according to their proficiency level. Then, a pre-test of Paribakht and Wesche's Vocabulary Knowledge Scale was given to each gr...

Recent language production studies have started to use electrophysiological measures to investigate the time course of word selection processes. An important contribution with respect to this issue comes from studies that have relied on an effect of semantic context in the semantic blocking task. Here we used this task to further establish the empirical pattern associated with the effect of sem...

This paper offers a unified approach to Italian spatial prepositions, such as di fronte a ‘in front of’, verso ‘towards’, in ‘in’, dietro a ‘behind’, and nel mezzo di ‘in the middle of’. Three assumptions play a key role. First, Italian spatial prepositions can differ sensibly in their morphological structure, but share the same syntactic properties. Second, their sentential distribution is in ...

We describe the Latent Semantic Indexing Subspace Signature Model (LSISSM) for semantic content representation of unstructured text. Grounded on Singular Value Decomposition (SVD), the model represents terms and documents by the distribution signatures of their statistical contribution across the topranking latent concept dimensions. LSISSM matches term signatures with document signatures accor...

In this paper we propose a new approach for determining the adequate sense of Arabic words. For that, we propose an algorithm based on information retrieval measures to identify the context of use that is the most closest to the sentence containing the word to be disambiguated. The contexts of use represent a set of sentences that indicates a particular sense of the ambiguous word. These contex...
