This paper presents different methods tested by the University of Avignon and Bertin at the TREC-7 evaluation. A first section describes several methodologies used for query expansion: synonymy and stemming. Relevance feedback is applied both to the TIPSTER corpora and Internet documents. In a second section, we describe a classification algorithm based on hierarchical and clustering methods. T...

persian natural language processing (nlp) researchers have many limitations to access linguistic tools which are suitable for text processing. therefore, researchin persian text processing is very limited. since dataset is an important requirement for experiments and their evaluation, we aimed to create appropriate corpora for information retrieval and natural language processing in persian. th...

This paper presents the multimodal corpora that are being collected and annotated in the Nordic NOMCO project. The corpora will be used to study communicative phenomena such as feedback, turn management and sequencing. They already include video material for Swedish, Danish, Finnish and Estonian, and several social activities are represented. The data are being annotated following an annotation...

When rules of transfer-based machine translation (MT) are automatically acquired from bilingual corpora, incorrect/redundant rules are generated due to acquisition errors or translation variety in the corpora. As a new countermeasure to this problem, we propose a feedback cleaning method using automatic evaluation of MT quality, which removes incorrect/redundant rules as a way to increase the e...

The paper compares how feedback is expressed via speech and head movements in comparable corpora of first encounters in three Nordic languages: Danish, Finnish and Swedish. The three corpora have been collected following common guidelines, and they have been annotated according to the same scheme in the NOMCO project. The results of the comparison show that in this data the most frequent feedba...

This study attempted to systematically inspect the impact of direct and indirect corrective feedbacks on the writing ability of EFL learners when using product/process based instructions. To do so, 110 female EFL learners, between the ages of 15 and 18, were randomly assigned into four experimental groups to receive four different kinds of treatments, namely product-based instruction with direc...

Testing long-term memory has dual benefits: It enhances learning and it helps learners discriminate what they know from what they do not know. The latter benefit, known as delayed judgment of learning (dJOL) effect, has been well documented, but in prior research participants have not been provided with test feedback. Yet when people study they almost universally a) get feedback and b) judge th...

We developed a distributed search system with the corresponding very large scale corpora from NTCIR5 WEB Task. And we arranged the scoring method which is based on link-structure of the Web documents to calculate lower cost. Our search system, which consists of 6 PCs could make indices for full texts size of about 1 TB. Additionally, we confirmed that our arranged scoring method made an improve...
