The study of intonation in a (fully) tone language presents both a challenge and an opportunity. The challenge is to see how a language which exploits F0 mainly for the purpose of lexical and grammatical contrasts succeeds in encoding the functions often expressed by means of intonation in non-tonal languages. As is well-known, word-level distinctions can be quite rich in tone systems, which co...

as a member of larger familyof formulaic sequences , lexical bundles play different discourse functions in written research articles. this study investigated the use of four-word lexical bundles in published research articles in medicine via natural language processing by computational linguistics. a corpus of 2,420,914 words was extracted from 790 research articles in 33 medical disciplines. f...

This study investigated whether Lexical Inferencing (L1) and Morphological Instruction (MI) can significantly affect EFL learners’ reading comprehension, furthermore, it also examined their effects on the learners’ vocabulary retention over time. 60 homogeneous EFLlearnerswere randomly assigned to two experimental and a control groups. After the pre-test, participants of the first experimental ...

Lewis (1993) recognized significance of word combinations including collocations by presenting lexical approach. Because of the crucial role of collocation in vocabulary acquisition, this research set out to evaluate the rate of collocations in Iranian EFL learners' writing production across L1 and L2. In addition, L1 interference with L2 collocational use in the learner' writing samples was st...

Mechanisms for representing lexically the bulk of syntactic and semantic information for a language have been under active development, as is evident in the recent studies contained in this volume. Our study serves to highlight some of the most useful tools available for structured lexical representation, in particular (multiple) inheritance, default specification, and lexical rules. It then il...

We consider the problem of tracking information over time and across sources in clusters of news stories about emergency events. While previous approaches have focused on finding new information at the document and sentence levels (e.g. TDT FSD and the TREC Novelty track, respectively), we are interested in following information at the factual level. Specifically, we propose to develop a “fact ...

Retrieval systems implementing query-based search routinely encounter difficulties related to lexical ambiguity. Frequent attempts have been made in the fields of Information Retrieval (IR), Artificial Intelligence (AI) and Natural Language Processing (NLP) to address this problem, yet it remains unsolved. This thesis introduces a novel methodology known as co-active search that expresses the u...

This  qualitative  study  investigates  the  uses  of  be  in  Contemporary  English.  Based  on  this  study, one  easy  claim  and  one  more  difficult  claim  are  proposed.  The  easy  claim  is  that  the  traditional distinction between be as a lexical verb and be as an auxiliary is faulty. In particular, 'copular-be', traditionally considered to be a lexical verb, is in fact a prototypi...
