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...

ABSTRACT Information Technology enhances the possibility for people to communicate when separated in time and space. In Distance Education this means new tools for tutoring and collaboration. But what effects does IT have on the interaction between students and teachers? This paper presents results from an exploratory study of a distance education project at the University of Trollhättan Uddeva...

This paper describes the Chinese Word Segmenter for the fourth International Chinese Language Processing Bakeoff. Base on Conditional Random Field (CRF) model, a basic segmenter is designed as a problem of character-based tagging. To further improve the performance of our segmenter, we employ a word-based approach to increase the in-vocabulary (IV) word recall and a post-processing to increase ...

This paper proposes a lexicon-constrained character model that combines both word and character features to solve complicated issues in Chinese morphological analysis. A Chinese character-based model constrained by a lexicon is built to acquire word building rules. Each character in a Chinese sentence is assigned a tag by the proposed model. The word segmentation and partof-speech tagging resul...

BACKGROUND Mobile phone-based assessment may represent a cost-effective and clinically effective method of monitoring psychotic symptoms in real-time. There are several software options, including the use of native smartphone applications and text messages (short message service, SMS). Little is known about the strengths and limitations of these two approaches in monitoring symptoms in individu...

An increasing number of studies have investigated the effects of different types of corrective feedback. However, doubts have been raised whether field (in)dependent (FI/FD) L2 learners benefit differently from the explicit type of corrective feedback (i.e., metalinguistic). This study examined the (possible) effects of metalinguistic feedback on FI/FD intermediate L2 learners’ writing accuracy...

Personalisation in full text retrieval or full text filtering implies reweighting of the query terms based on some explicit or implicit feedback from the user. Relevance feedback inputs the user’s judgements on previously retrieved documents to construct a personalised query or user profile. This paper studies relevance feedback within two probabilistic models of information retrieval: the firs...

Feedback suggestive of mistaken eyewitnesses claiming that they identified the correct person leads to distorted retrospective judgments of certainty, view, and other testimony-relevant measures. This feedback effect can be significantly mitigated if witnesses later learn that the feedback source did not know which lineup member was the correct person and had a manipulative intent (post-feedbac...

It is often assumed that raw MT output requires post-editing if it is to be used for more than gisting purposes. However, we know little about how end users engage with raw machine translated text or postedited text, or how usable this text is, in particular if users have to follow instructions and act on them. The research project described here measures the usability of raw machine translated...
