Reviews are text-based feedback provided by a reviewer to the author of a submission. Reviews play a crucial role in providing feedback to people who make assessment decisions (e.g. deciding a student’s grade, purchase decision of a product). It is therefore important to ensure that reviews are of a good quality. In our work we focus on the study of academic reviews. A review is considered to b...

Despite the increasing use of groupware technologies in education, there is little evidence of their impact, especially within an enquiry-based learning (EBL) context. In this paper, we examine the use of a commercial standard Group Intelligence software called GroupSystems®ThinkTank. To date, ThinkTank has been adopted mainly in the USA and supports teams in generating ideas, categorising, pri...

in this paper, a novel method is developed for designing the output feedback controller for static synchronous series compensator (sssc). in the proposed method, the problem of selecting the output feedback gains for the sssc controllers is changed into an optimization problem with a time domain-based objective function.then, it is solved by using the particle swarm optimization (pso) algorithm...

web search engines are one of the most popular tools on the internet which are widely-used by expert and novice users. constructing an adequate query which represents the best specification of users’ information need to the search engine is an important concern of web users. query expansion is a way to reduce this concern and increase user satisfaction. in this paper, a new method of query expa...

In the framework of our Reactive Virtual Trainer (RVT) project, we are developing an Intelligent Virtual Agent (IVA) capable to act similarly to a real trainer. Besides presenting the physical exercises to be performed, she keeps an eye on the user. She provides feedback whenever appropriate, to introduce and structure the exercises, to make sure that the exercises are performed correctly, and ...

While the corpus-based research relies on human annotated corpora, it is often said that a non-negligible amount of errors remain even in frequently used corpora such as Penn Treebank. Detection of errors in annotated corpora is important for corpus-based natural language processing. In this paper, we propose a method to detect errors in corpora using support vector machines (SVMs). This method...

This paper presents a series of experiments on automatic transcription and classification of fillers and feedbacks in conversational speech corpora. A feature combination of PCA projected normalized F0 Constant-Q Cepstra and MFCCs has shown to be effective for standard Hidden Markov Models (HMM). We demonstrate how to model both speaker channel with coupled HMMs and show expected improvements. ...

This paper describes the TTC Web platform, an online demonstrator to show the whole pipeline to compile bilingual terminologies out of comparable corpora gathered from the web using the tools developed in the TTC project Terminology Extraction, Translation Tools and Comparable Corpora. We present the whole chain which has been integrated into the platform, as well as their main components: a fo...
