Evaluating multimodal relevance feedback techniques for medical image retrieval

Medical image retrieval can assist physicians in finding information supporting their diagnosis and fulfilling information needs. Systems that allow searching for medical images need to provide tools for quick and easy navigation and query refinement as the time available for information search is often short. Relevance feedback is a powerful tool in information retrieval. This study evaluates relevance feedback techniques with regard to the content they use. A novel relevance feedback technique that uses both text and visual information of the results is proposed. The two information modalities from the image examples are fused either at the feature level using the Rocchio algorithm or at the query list fusion step using a common late fusion rule. Results using the ImageCLEF 2012 benchmark database for medical image retrieval show the potential of relevance feedback techniques in medical image retrieval. The mean average precision (mAP) is used as the evaluation metric and the proposed method outperforms commonly-used methods. The baseline without feedback reached 16 % whereas the relevance feedback with 20 images reached up to 26.35 % with three steps and when using 100 images up to 34.87 % in four steps. Most improvements occur in the first two steps of relevance feedback and then results start to become relatively flat. This might also be due to only using positive feedback as negative feeback often also improves results after more steps. The effect of relevance feedback in automatically spelling corrected and translated queries is investigated as well. Results without mistakes were better than spell-corrected results but the spelling correction more than double results over non-corrected retrieval. Multimodal relevance feedback has shown to be able to help visual medical information retrieval. Next steps include integrating semantics into relevance feedback techniques to benefit from the structured knowledge of ontologies and experimenting on the fusion of text and visual information.     

Measuring peer feedback in face-to-face and online public-speaking workshops

This study explores the use of a survey instrument relating to feedback within the organizational context to measure student perceptions of peer feedback in a speech workshop activity conducted in a public-speaking class. A 20-item instrument was adapted from Steelman, Levy, and Snell’s Feedback Environment Scale (FES) for coworker feedback (The Feedback Environment Scale: Construct definition, measurement, and validation. Educational and Psychological Measurement 2004; 64: 165–184. doi: 10.1177/0013164403258440). Results suggest that four constructs adopted from Steelman et al. (source credibility, feedback quality, favorable feedback, and unfavorable feedback) appear suited to gauge student perceptions of peer feedback. Further analyses on the variables indicated no significant differences, regardless of whether the activity took place face-to-face or online.     

Development and construct validation of the sensitivity to feedback scale

A scale measuring individual levels of sensitivity to feedback was developed. Factor analysis revealed four factors — Sensitivity to Attention, to Socially Desirable Feedback, to Socially Undesirable Feedback, and Anticipation of Response. Sensitivity to feedback is positively correlated with self‐monitoring, self‐esteem, and interaction involvement; negatively correlated with communication apprehension.     

The relationship between college student feedback orientation and classroom engagement

ABSTRACT

This study explored the relationship between the four dimensions of students’ feedback orientation (i.e., utility, retention, confidentiality, and sensitivity) and the four dimensions of students’ classroom engagement (i.e., silent in-class, oral in-class, thinking about course content, and out-of-class) using the tenets of Feedback Intervention Theory (FIT) as a guide. Participants were 208 undergraduate students enrolled in a variety of introductory communication courses at a large mid-Atlantic university. It was found that varying combinations of students’ feedback orientation influence students’ engagement, providing further support for FIT. Specifically, feedback utility was positively related to all four dimensions of student engagement. Furthermore, feedback confidentiality was negatively related to oral in-class behaviors. Future research should continue to examine the influence of instructional feedback on students’ classroom engagement.

Durational differences in speech production under normal and delayed auditory feedback

The relationship between an individual's social perspective‐taking capacity and the complexity of that individual's dimensions for construing the behavior and character of others was examined within a general constructivist framework. A significant correlation was found supporting the hypothesis that the more differentiated the construction system of the individual the better he/she should be able to construe the perspectives of others in social situations. Evidence is also offered demonstrating the validity and reliability of the Social Perspective Task as a research instrument for examining the mode of construal of the individual.     

Certain effects on vocal pitch of frequency modulated instantaneous auditory feedback

The dynamic relationships between manipulations of auditory feedback and the vocal responses of the individual have been of both theoretical and practical interest. The present study sought to investigate one of the auditory feedback variables, namely, vocal pitch, which had heretofore received little attention. An attempt was made to assess the effects of an experimental pitch‐shift of auditory feedback on the speaker's own vocal pitch, while maintaining normal relationships of the other feedback variables. Vocal pitch changes were seen to accompany the pitch‐shifts of auditory feedback. However, these differences were not statistically significant and did not prove predictable from the amount and direction of change in the auditory feedback.

Mining service quality feedback from social media: A computational analytics method

In spite of the growing opportunities and demands for using social media to assist government decision-making, few studies have investigated social media sentiments toward public services due to the large volume and noisy nature of big data. Taking a design science approach, this paper suggests a systematic method to assign tweets into each of the SERVQUAL dimensions to identify sentiments and track perceived service quality of healthcare services for policy makers. The method consists of (1) identifying more reliable topic sets through repeated latent Dirichlet allocation (LDA) and clustering; and (2) classifying tweets using topics based on an existing theory for service quality. The method is applied to tweets on the quality of NHS of the UK to demonstrate its usability. We measured social perceptions of healthcare service quality and identified keywords for each SERVQUAL dimension. Moreover, a comparison between the social perceptions derived from the tweets and traditional survey result on the same service quality shows the similarity which confirms the usability of the proposed method. The method has a practical value as a complimentary tool for the more expensive national scale surveys as well as academic value as a novel method integrating text mining with theoretically sound quality framework, SERVQUAL.     

Map of dermatology: 'first-impression' user feedback and agenda for further development

BACKGROUND: Map of Dermatology (http://healthcybermap.org/dermap/) is a free web resource that enables users to search for images of skin conditions by body region and morphology rather than by condition name, which is much more useful and natural in answering questions about unknown clinical presentations/diagnoses, especially for non-specialists. OBJECTIVES AND METHODS: This paper presents responses received from twelve users, including specialist dermatologists, non-specialists (some with interests in health informatics), and lay persons, who provided their 'first-impression' feedback on Map of Dermatology by responding to a very short e-mail questionnaire covering service usefulness and interface usability. The paper also provides a brief review of the gaps in current online dermatology information service provision in general. RESULTS: The overall user feedback received was very positive. An exploratory discussion of the arguments and possibilities for radically improving Map of Dermatology to produce 'the ultimate web-based dermatology diagnostic tool' is also provided, together with some desiderata and preliminary 'design and feature specifications' for such a tool based on users' suggestions, the gaps highlighted in other existing online dermatology tools, and the author's own reflections and experience. CONCLUSIONS: When successfully developed, the proposed tool is expected to have significant potential for efficiently and effectively addressing many of the currently unmet educational needs of clinicians.

Effects of positive and negative audience feedback on selected variables of speech behavior

Much empirical evidence suggests that explanations for innovation outcomes should be located in an understanding of users' responses to innovations (Ashford, 1988; Fulk, 1993; Lewis &; Seibold, 1993; Miller, Johnson, &; Grau, 1994; Poole &; DeSanctis, 1990). Unfortunately, researchers have neglected to pursue systematic studies of behavioral responses to innovations in accounting for particular innovation outcomes. The investigation reported draws on previous research that isolated three dimensions of interaction‐based coping responses: favorableness, decidedness, and focus (self vs. other). The present study tests the relative effects of several antecedents to users' (N= 216) behavioral coping responses to quality programs in four organizations. Results of hierarchical regression analyses indicated that users' attitudes, concerns for performance, normative influence, and uncertainty, and their perceptions of the context of change affect each of the three dimensions of their behavioral coping responses.

Experiments with dictionary-based CLIR using graded relevance assessments: Improving effectiveness by pseudo-relevance feedback

Research on cross-language information retrieval (CLIR) has typically been restricted to settings using binary relevance assessments. In this paper, we present evaluation results for dictionary-based CLIR using graded relevance assessments in a best match retrieval environment. A text database containing newspaper articles and a related set of 35 search topics were used in the tests. First, monolingual baseline queries were automatically formed from the topics. Secondly, source language topics (in English, German, and Swedish) were automatically translated into the target language (Finnish), using structured target queries. The effectiveness of the translated queries was compared to that of the monolingual queries. Thirdly, pseudo-relevance feedback was used to expand the original target queries. CLIR performance was evaluated using three relevance thresholds: stringent, regular, and liberal. When regular or liberal threshold was used, a reasonable performance was achieved. Using stringent threshold, equally high performance could not be achieved. On all the relevance thresholds the performance of the translated queries was successfully raised by pseudo-relevance feedback based query expansion. However, the performance of the stringent threshold in relation to the other thresholds could not be raised by this method.
