We propose a novel method for online misinformation analysis based on a Wittgensteinian approach. We found no previous work that use Wittgenstein’s early philosophy for misinformation analysis. The works of Ludwig Wittgenstein (1889-1951) are usually divided into two: the early and the later philosophy. Wittgenstein’s book Tractatus Logico-Philosophicus (TL-P) is regarded as his early masterpiece. The TL-P is concerned with the role facts play in the world. According to TL-P, the world is composed of facts and we connect with facts by our thoughts. Our thoughts picture the world and are expressed through propositions. The system for online content analysis, described here, is a descriptive tool to clarify the thoughts and propositions found within online content analysed. Web-based written non-graphical information (articles, commentary etc.) is analysed and then scored based on criteria designed to evaluate the information quality of the content. Our hypothesis is that when applied to Web browsers and online social media platforms, the rating produced by this information quality analysis system will help users discern content qualitatively and engage more analytically with other users.

Quality Check

A global online analytical quality check system (and method) for online content analysis is presented. Web-based information (articles, commentary etc.) is analysed then scored based on criteria designed to evaluate the quality of analytical content. Content is then categorised as ‘analytical’ or ‘non-analytical’. Further labelling of the intrinsic nature of the content (e.g. ‘satire’ ‘political’ ‘scientific’) and users’ (content consumers) ratings completes the process. Applied to Web browsers and online social media platforms: the rating produced by the quality check can help users discern quality content, avoid being misinformed and engage more analytically with other users. This system can also be viewed as a theory of information quality.

How can misinformation online (World Wide Web) be effectively analysed? Online platforms initially left content consumers to discern for themselves whether information online was true or false. Outright censoring of content followed and then fact-checking. We propose in this paper that misinformation analysis should aim to make clear what is stated by clarifying the propositions and claims in such content. The early philosophy of Ludwig Wittgenstein (1889-1951) is relevant for such analysis. Presented here is an online content information quality check model for written (non-graphical) misinformation analysis and prevention. This model is inspired by Wittgenstein’s book Tractatus Logico-Philosophicus. Applied to Web browsers and online social media platforms, the rating and labelling of content with this model can help users discern content qualitatively, avoid being misinformed and engage more analytically with other users. This Wittgensteinian model can also be viewed as a theory of information quality.

BACKGROUND:The aim of this study was to evaluate the information quality of YouTube videos on hallux valgus. METHODS:A YouTube search was performed using the keyword 'hallux valgus' to determine the first 300 videos related to hallux valgus. A total of 54 videos met our inclusion criteria and evaluated for information quality by using DISCERN, Journal of the American Medical Association (JAMA) and hallux valgus information assessment (HAVIA) scores. Number of views, time since the upload date, view rate, number of comments, number of likes, number of dislikes, video power index (VPI) values were calculated to determine video popularity. Video length (sec), video source and video content were also noted. The relation between information quality and these factors were statistically evaluated. RESULTS:The mean DISCERN score was 30.35{plus minus}11.56 (poor quality) (14-64), the mean JAMA score was 2.28{plus minus}0.96 (1-4), and the mean HAVIA score was 3.63{plus minus}2.42 (moderate quality) (0.5-8.5). Although videos uploaded by physicians had higher mean DISCERN, JAMA, and HAVIA scores than videos uploaded by non-physicians, the difference was not statistically significant. Additionally, view rates and VPI values were higher for videos uploaded by health channels, but the difference did not reach statistical significance. A statistically significant positive correlation was found between video length and DISCERN (r= 0.294, p= 0.028), and HAVIA scores (r= 0.326, p= 0.015). CONCLUSIONS:This present study demonstrated that the quality of information available on YouTube videos about hallux valgus was low and insufficient. Videos containing accurate information from reliable sources are needed to educate patients on hallux valgus, especially in less frequently mentioned topics such as postoperative complications and healing period.

Technology Trends

Today's learners are intrinsically motivated in that they are apt to analyze, synthesize, internalize, rebuild, share, and disseminate knowledge not only with their instructors, but also their peers, and the greater community, including a plethora of learning communities from across the world. Web-based technologies play a key role in this learning process. Particularly online social media networks and mobile technologies, the two selected technology trends evaluated in this paper, are thriving in online learning/teaching settings, immensely helping students acquire valid learning gains. These technologies are not a fad, a myth, or talk-of-the-day in learning and teaching environments in any given discipline. With that said, there are also certain issues and challenges that accompany these media and technologies for learning and teaching practices, which will also be addressed in this paper. Finally, future implications on these trends and issues in DL will be further discussed with the hope that educational leaders can draw on them for further inquiry and development in the field.

Purpose. The study aimed to evaluate the visual quality of forme fruste keratoconus (FFK) and mild and moderate keratoconus by using an optical quality analysis system II (OQAS-II) and to explore the correlation between optical quality parameters and the disease progression. Methods. Twenty-one normal eyes, twenty-one FFK eyes, twenty-one mild keratoconus eyes, and twenty-one moderate keratoconus eyes were included in this prospective study. The optical quality parameters, such as object scatter index (OSI), modulation transfer function cutoff (MTF cutoff), strehl ratio (SR), and OQAS-II values at contrasts of 100% (OV-100), 20% (OV-20), and 9% (OV-9), were measured by OQAS-II. The repeatability of these parameters was analyzed by intraclass correlation coefficient (ICC), repeatability coefficient (RC), and coefficient of variation (CVw). Correlations between optical quality parameters and mean central keratometry readings (Kmean) were evaluated. The sensitivity and specificity of the parameters were analyzed using the receiver operating characteristic (ROC). Results. All the optical quality parameters among four groups showed good repeatability (all ICC≥0.75). The MTF cutoff, SR, OV-100, OV-20, OV-9 in FFK, mild and moderate keratoconus eyes were significantly lower than those in the normal group (all P<0.05). The ROC analyses of the MTF cutoff, SR, OV-100, OV-20, and OV-9 showed significant area under the curve (AUC) in discriminating FFK form normal, mild keratoconus from FFK, and moderate keratoconus from mild keratoconus (all P<0.05). The OSI in mild and moderate keratoconus eyes were significantly higher than that in FFK and normal group (all P<0.05), while the OSI showed no significant difference between the FFK group and normal group (P>0.05). The ROC analyses of the OSI showed significant AUC in discriminating mild keratoconus from FFK and moderate keratoconus from mild keratoconus (all P<0.05). In addition, the MTF cutoff was closely correlated to Kmean in keratoconus eyes (r = −0.710, P<0.001). Conclusion. The repeatability of OQAS-II is good in measuring visual quality of normal as well as FFK, mild, and moderate keratoconus. The visual quality of the FFK, mild, and moderate keratoconus is worse than that in normal eyes. The OQAS-II has the potential value in screening FFK from normal eyes and might be a useful tool for evaluating the progression of keratoconus.

ObjectivesIt is the aim of the current research to identify some common functionalities of postnatal application, and to determine the quality of the information content of postnatal depression application using validated scales that have been applied for applications in other specialties.Settings and participantsTo determine the information quality of the postnatal depression smartphone applications, the two most widely used smartphone application stores, namely Apple iTunes as well as Google Android Play store, were searched between 20May and 31 May. No participants were involved. The inclusion criteria for the application were that it must have been searchable using the keywords ‘postnatal’, ‘pregnancy’, ‘perinatal’, ‘postpartum’ and ‘depression’, and must be in English language.InterventionThe Silberg Scale was used in the assessment of the information quality of the smartphone applications.Primary and secondary outcomes measureThe information quality score was the primary outcome measure.ResultsOur current results highlighted that while there is currently a myriad of applications, only 14 applications are specifically focused on postnatal depression. In addition, the majority of the currently available applications on the store have only disclosed their last date of modification as well as ownership. There remain very limited disclosures about the information of the authors, as well as the references for the information included in the application itself. The average score for the Silberg Scale for the postnatal applications we have analysed is 3.0.ConclusionsThere remains a need for healthcare professionals and developers to jointly conceptualise new applications with better information quality and evidence base.
