{"title":"Quality assessment of web-based information on type 2 diabetes","authors":"Didem Ölçer, T. Taşkaya-Temizel","doi":"10.1108/oir-02-2021-0089","DOIUrl":"https://doi.org/10.1108/oir-02-2021-0089","url":null,"abstract":"PurposeThis paper proposes a framework that automatically assesses content coverage and information quality of health websites for end-users.Design/methodology/approachThe study investigates the impact of textual and content-based features in predicting the quality of health-related texts. Content-based features were acquired using an evidence-based practice guideline in diabetes. A set of textual features inspired by professional health literacy guidelines and the features commonly used for assessing information quality in other domains were also used. In this study, 60 websites about type 2 diabetes were methodically selected for inclusion. Two general practitioners used DISCERN to assess each website in terms of its content coverage and quality.FindingsThe proposed framework outputs were compared with the experts' evaluation scores. The best accuracy was obtained as 88 and 92% with textual features and content-based features for coverage assessment respectively. When both types of features were used, the proposed framework achieved 90% accuracy. For information quality assessment, the content-based features resulted in a higher accuracy of 92% against 88% obtained using the textual features.Research limitations/implicationsThe experiments were conducted for websites about type 2 diabetes. As the whole process is costly and requires extensive expert human labelling, the study was carried out in a single domain. However, the methodology is generalizable to other health domains for which evidence-based practice guidelines are available.Practical implicationsFinding high-quality online health information is becoming increasingly difficult due to the high volume of information generated by non-experts in the area. The search engines fail to rank objective health websites higher within the search results. The proposed framework can aid search engine and information platform developers to implement better retrieval techniques, in turn, facilitating end-users' access to high-quality health information.Social implicationsErroneous, biased or partial health information is a serious problem for end-users who need access to objective information on their health problems. Such information may cause patients to stop their treatments provided by professionals. It might also have adverse financial implications by causing unnecessary expenditures on ineffective treatments. The ability to access high-quality health information has a positive effect on the health of both individuals and the whole society.Originality/valueThe paper demonstrates that automatic assessment of health websites is a domain-specific problem, which cannot be addressed with the general information quality assessment methodologies in the literature. Content coverage of health websites has also been studied in the health domain for the first time in the literature.","PeriodicalId":143302,"journal":{"name":"Online Inf.

This study provides empirical evidence that semiprivate space at the family level affects students' access to online education.Design/methodology/approachStudents from 1,565 low-income households in China were surveyed, and a multivariate logistic regression analysis was conducted on the hypothesized factors that affect access to online education at home.FindingsThe results show that the absence of computers, smartphones and broadband networks at home severely hinders children's access to online education, and even leads to their exclusion from it. Children with their fathers or paternal grandfathers as guardians have a lower probability of receiving online education at home. It was also found that the higher the education level of the head of the household, the more likely it is that children will receive online education at home.Originality/valueThis study is one of the first to examine online accessibility at the family level. It also demonstrates that the semiprivate space at the family level may limit opportunities for students who would otherwise pursue online education at home.","PeriodicalId":143302,"journal":{"name":"Online Inf.

Chen, Jin-Cheon Na, Luke Kien-Weng Tan, Mark Chong, Murphy Choy","doi":"10.1108/oir-08-2021-0422","DOIUrl":"https://doi.org/10.1108/oir-08-2021-0422","url":null,"abstract":"PurposeThe COVID-19 pandemic has spurred a concurrent outbreak of false information online. Debunking false information about a health crisis is critical as misinformation can trigger protests or panic, which necessitates a better understanding of it. This exploratory study examined the effects of debunking messages on a COVID-19-related public chat on WhatsApp in Singapore.Design/methodology/approachTo understand the effects of debunking messages about COVID-19 on WhatsApp conversations, the following was studied. The relationship between source credibility (i.e. characteristics of a communicator that affect the receiver's acceptance of the message) of different debunking message types and their effects on the length of the conversation, sentiments towards various aspects of a crisis, and the information distortions in a message thread were studied. Deep learning techniques, knowledge graphs (KG), and content analyses were used to perform aspect-based sentiment analysis (ABSA) of the messages and measure information distortion.FindingsDebunking messages with higher source credibility (e.g. providing evidence from authoritative sources like health authorities) help close a discussion thread earlier. Shifts in sentiments towards some aspects of the crisis highlight the value of ABSA in monitoring the effectiveness of debunking messages. Finally, debunking messages with lower source credibility (e.g. stating that the information is false without any substantiation) are likely to increase information distortion in conversation threads.Originality/valueThe study supports the importance of source credibility in debunking and an ABSA approach in analysing the effect of debunking messages during a health crisis, which have practical value for public agencies during a health crisis. Studying differences in the source credibility of debunking messages on WhatsApp is a novel shift from the existing approaches. Additionally, a novel approach to measuring information distortion using KGs was used to shed insights on how debunking can reduce information distortions.","PeriodicalId":143302,"journal":{"name":"Online Inf.

Data reliability is a matter of debate. The online dissemination of information has been a field for the reproduction of fake news. International Federation of Library Associations and Institutions (IFLA) states that libraries are part of the answer to this ever-increasing problem. The purpose of the study is to investigate libraries' role in combating the fake news phenomenon.Design/methodology/approachThe study was designed to record attitudes of professionals and students of library science on the libraries' role in the battle against misinformation. The study was conducted through an online survey using a questionnaire consisted of closed-ended, seven-point Likert scale questions. The data collected were subjected to a descriptive statistical analysis. The median was used to present the results. In order to perform analysis between genders, as well as age groups, the non-parametric criteria Mann–Whitney U and Kruskal–Wallis were applied to determine the existence of differences in participants' beliefs. Spearman's rank correlation test was used in order to examine whether participants' replies were interrelated.FindingsResponses by 434 individuals were obtained. Participants highlighted primarily the educational role of libraries and agreed that the fake news phenomenon is an opportunity to promote the libraries' role in society. No clear direction was recorded in the participants' beliefs about the plethora of information and fake news as a potential threat to libraries. The respondents partly agreed that the plethora of information caused work-related emotional disorders and feeling that the respondents were not able to keep track of developments in the field. Finally, the study depicted the participants' need for training on combating fake news, information sources evaluation and recognizing predatory journals.Originality/valueThe study's significance lies in the following: the study contributes to the recording of professionals' as well as students of library science views about (1) libraries' role, (2) working environment and (3) training needs, concerning fake news and the overabundance of information in the digital era.","PeriodicalId":143302,"journal":{"name":"Online Inf.

In addition, Schadenfreude is increasingly common in the era of ideological polarization. Previous literature may have discussed the cause and outcomes of schadenfreude in general but not specifically related to ideological polarization. This study aims to serve to establish a more informed understanding of online schadenfreude as an outcome of ideological polarization and help society recover from the damages.Design/methodology/approachThe authors adopted a case research method with netnography for our study, given that the authors are exploring the phenomena of online schadenfreude, which involves multiple dimensions.FindingsThe authors identified a three-level model that illustrates how schadenfreude is driven as an outcome of ideological polarization, i.e. macro-environment, camp/partisan and target. These factors of different levels involve political viewpoint differences, perceived appearance, personal conduct, aggressive norms and polarized environment with a lack of conventional opinion expression channel. Moreover, attackers may demonstrate a belief in Karma, creativity and a sense of humor and may call for actions.Originality/valueWhile previous literature focused on the relationship between fake news, echo chambers and ideological polarization, this study is a relatively earlier one on studying schadenfreude as an outcome of ideological polarization, which would facilitate to formulate the solution to repair the damages created to ideological polarization. The authors also discussed the enablers as well as the self-reinforcing nature of ideological polarization, and provided some practical implications for politicians and government officials.","PeriodicalId":143302,"journal":{"name":"Online Inf.
