TL;DR: This study provides a fine-grained analysis of the implicit and explicit language used by consumers to express sentiment in text and demonstrates the differential impacts of activation levels, implicit sentiment expressions, and discourse patterns on overall consumer sentiment.
Abstract: Deciphering consumer’s sentiment expressions from Big Data (e.g., online reviews) has become
a managerial priority to monitor product and service evaluations. However, Sentiment Analysis,
the process of automatically distilling sentiment from text, provides little insight regarding the
language granularities beyond the use of positive and negative words. Drawing on Speech Act
Theory, this study provides a fine-grained analysis of the implicit and explicit language used by
consumers to express sentiment in text. An empirical text mining study using more than 45,000
consumer reviews, demonstrates the differential impacts of activation levels (e.g., tentative
language), implicit sentiment expressions (e.g., commissive language), and discourse patterns
(e.g., incoherence) on overall consumer sentiment (i.e., star ratings). In two follow-up studies,
we demonstrate that these speech act features also influence the readers’ behavior and are
generalizable to other social media contexts such as Twitter and Facebook. We contribute to
research on consumer sentiment analysis by offering a more nuanced understanding of consumer
sentiments and their implications

TL;DR: The authors showed that the most likely explanation of the hard-easy effect in subjective probability judgments is in terms of response criteria, since error by itself cannot fully explain observed underconfidence phenomena.

TL;DR: This state‐of‐the‐art report presents a summary of the progress that has been made by highlighting and synthesizing select research advances and presents opportunities and challenges to enhance the synergy between machine learning and visual analytics for impactful future research directions.
Abstract: Visual analytics systems combine machine learning or other analytic techniques with interactive data visualization to promote sensemaking and analytical reasoning. It is through such techniques that people can make sense of large, complex data. While progress has been made, the tactful combination of machine learning and data visualization is still under-explored. This state-of-the-art report presents a summary of the progress that has been made by highlighting and synthesizing select research advances. Further, it presents opportunities and challenges to enhance the synergy between machine learning and visual analytics for impactful future research directions.

TL;DR: Factors influencing outcome with treatment for amblyopia are occlusion dose, the rate of delivery and cumulative dose worn, the initial severity of the amblyopy, binocular vision status, fixation of the Amblyopic eye, and the age of the subject at the start of treatment.
Abstract: PURPOSE To identify factors that influence the outcome of treatment for unilateral amblyopia, as a part of the Monitored Occlusion Treatment of Amblyopia Study (MOTAS). METHODS This was an intervention study consisting of three nonoverlapping phases: "Baseline", "refractive adaptation" (18 weeks of full-time spectacle wear), and "occlusion" (6 hours of patching per day, objectively monitored). Condition factors: type of amblyopia, age of participant, initial severity of amblyopia, fixation, and binocular vision status; treatment factors: refractive adaptation and occlusion (total dose [hours] and dose rate [hours per day]) were assessed for their influence on visual outcome. Visual outcome was expressed in three ways: logMAR (logarithm of the minimum angle of resolution) change, residual amblyopia, and proportion of the deficit corrected. RESULTS The study included 85 participants (mean age, 5.1 +/- 1.4 years) with amblyopia associated with strabismus (n = 32) or anisometropia (n = 20) or associated with both anisometropia and strabismus (n = 33). Treatment factors: cumulative occlusion dose exceeding 50 hours, and dose rates > or =1 hour per day resulted in (P < or = 0.01) lower residual amblyopia and a greater proportion of the deficit corrected. Condition factors associated with poor outcome (high residual amblyopia) were presence of eccentric fixation, severe initial amblyopia, and no binocular vision. CONCLUSIONS Factors influencing outcome with treatment for amblyopia are occlusion dose (the rate of delivery and cumulative dose worn), the initial severity of the amblyopia, binocular vision status, fixation of the amblyopic eye, and the age of the subject at the start of treatment.
