The present study addresses a long-standing assumption in the field of applied linguistics: that presenting new second language (L2) vocabulary in semantically grouped sets is an effective method of teaching. Participants learned 32 new L2 labels for concepts from four different semantic categories in either a related or unrelated condition. At test, participants translated words in both transl...
In this work, we describe a subword unit approach for information retrieval of items by voice. An algorithm based on the minimum description length (MDL) principle converts an index written in terms of words into an index written in terms of phonetic subword units. A speech recognition engine that uses a language model and pronounciation dictionary built from such an inventory of subword units ...
One of the major problems of modern Information Retrieval (IR) systems is the vocabulary Problem that concerns with the discrepancies between terms used for describing documents and the terms used by the researcher to describe their information need. We have implemented an automatic thesurs, the system was built using Vector Space Model (VSM). In this model, we used Cosine measure similarity. I...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Japanese university students learning English as a foreign language (EFL) encountered 10 target words in 3 sets of 10 short contexts that were rated on the amount of information available to infer the target words’ meanings. One group of learners met the target words in contexts rated more highly than the contexts read by the other group. A surprise vocabulary test that measured recall of form,...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
Semantic maps ensure a high potential to facilitate enhanced quality of understanding words. ESL students are often presented with new English vocabulary items that many times pre-organized in sets semantically related Although there is an assumption word grouping facilitates the activities for learning, little or no empirical justification offered by researchers support employing this teaching...
Open domain question answering (QA) systems have to bridge the potential vocabulary mismatch between a question and its candidate answers. One can view this as a recall problem and address it accordingly. Recall oriented strategies to QA may generate considerable amounts of noise. To combat this, many open domain QA systems contain an explicit filtering or re-ranking component, which often chec...
Controlled vocabularies enhance precision and recall but sometimes they achieve this at the expense of imposing a prescribed terminology and a homogeneous worldview upon a heterogeneous user community. Folksonomies allow end-users the freedom to describe content any way they want, but in doing so they create meta noise which diminishes precision and recall. This paper presents an alternative mo...
Vocabulary acquisition is essential to achieve fluency in the target language; however, it a daunting and unending task for second language learners due large number of words required be learne. This two-group, pre/post/delayed post-test quasi-experimental study aims investigate whether English as Foreign Language (EFL) could learn new incidentally from reading texts their coursebooks there was...
