This study was designed to investigate the effects of providing feedback in the interactive environment of wiki on improving the grammatical accuracy of Iranian EFL learners’ writing skill as well as the attitudes of Iranian EFL learners’ toward receiving feedback via wiki. To do so, 50 intermediate Iranian EFL learners, who were chosen by an OPT (Oxford Placement Test) participated in this stu...

In this paper, we initiate a theoretical study of the problem of clustering data under interactive feedback. We introduce a query-based model in which users can provide feedback to a clustering algorithm in a natural way via split and merge requests. We then analyze the “clusterability” of different concept classes in this framework — the ability to cluster correctly with a bounded number of re...

We tested two relevance feedback models, an adaptive linear model and a probabilistic model, using massive feedback query expansion in TREC-5 (Sumner & Shaw, 1997), experimented with a three-valued scale of relevance and reduced feedback query expansion in TREC-6 (Sumner, Yang, Akers & Shaw, 1998), and examined the effectiveness of relevance feedback using a subcollection and the effect of syst...

Abstract We report on a three-week field study in which participants from nine households were asked to annotate their domestic electricity consumption data using prototype interactive visualisation. Through an analysis of the annotations and semi-structured interviews, our findings suggest that intervention helped develop detailed accurate understanding data. Our results energy visualisations ...

In this paper, we report a real-time gesture driven interactive system with multimodal feedback for performing arts, especially dance. The system consists of two major parts: a gesture recognition engine and a multimodal feedback engine. The gesture recognition engine provides real-time recognition of the performer’s gesture based on the 3D marker coordinates from a marker-based motion capture ...

In classical information theory it is well-known that feedback does not improve the channel capacity. We demonstrate that this is not the case in the interactive setting by developing a new coding scheme for interactive communication over the binary symmetric channel (BSC) with feedback that allows recovery of the original communication with vanishing probability of error. More precisely, we sh...
