“…A knowledge entity is an object or a phenomenon recognized by an individual, while a knowledge category is the cognition acquired by abstracting a class of entities of which the commonalities are shared. Traditionally, when implementing a relational data model, it is necessary to first go through the domain knowledge and extract all the categories ( 20 ). Database tables are then established with fields corresponding to these categories of knowledge.…”

BackgroundWith significant advancements in the area of precision medicine, the breadth and complexity of the relevant knowledge in the field has increased significantly. However, the difficulty associated with dynamic modelling and the disorganization of such knowledge hinders its rapid development potential.ResultsTo overcome the difficulty in using the relational database model for dynamic modelling, and to aid in the organization of precision medicine knowledge, we developed the Mind Mapping Knowledgebase Prototyping (MMKP) tool. The MMKP implements a novel design that we call a “polymorphic foreign key”, which allows the establishment of a logical linkage between a single table field and a record from any table. This design has advantages in supporting dynamic changes to the structural relationships in precision medicine knowledge. Knowledge stored in MMKP is presented as a mind map to facilitate human interaction. When using this tool, medical experts may curate the structure and content of the precision knowledge in a flow that is similar to the human thinking process.ConclusionsThe design of polymorphic foreign keys natively supports knowledge modelling in the form of mind mapping, which avoids the hard-coding of medical logic into a rigid database schema and significantly reduces the workload that is required for adapting a relational data model to future changes to the medical logic. The MMKP tool provides a graphical user interface for both data management and knowledgebase prototyping. It supports the flexible customization of the data field constraints and annotations. MMKP is available as open-source code on GitHub: https://github.com/ZjuLiangsl/mmkp.

“…Despite the importance to provide up-to-date information, the results showed that timeliness has a lower correlation with user satisfaction. Searching for outdated information is related to casual searching behaviour without specific intention and is considered unimportant, as stated in social media web information [70]. This information searching behaviour is categorised as passive attention, where information searching is acquired subconsciously.…”

The digital gaming community appreciates the visual style classification system to search for information about a game product. However, scholars have discovered that the applied visual style classification system frequently leads to frustration and dissatisfaction among users owing to inaccurate search results. Moreover, there are yet any research studies that accurately measure user satisfaction during game searching activity in the digital game library based on the current visual style classification system. Therefore, this study was performed to investigate the influence of information quality components (Accuracy, Content, Ease of Use, Format, and Timeliness) on User Satisfaction during game searching activity in the digital game library. A cross-sectional study was conducted by distributing self-administered digital questionnaires to 239 game players in Malaysia. The 12-item instrument survey questionnaire, which consists of four main sections, adopted the End-user Computing Satisfaction (EUCS) model to examine the relationships between user satisfaction and information quality components. The results were then analysed using descriptive statistics, preliminary data analysis, and Confirmatory Factor Analysis (CFA). Based on the findings, more than half of the respondents were male (n = 139, 58.2%) with an age range between 19 and 24 years old, and 79.1% (n = 189) have experience in searching digital games based on visual styles. The EUCS model revealed that user satisfaction during game searching activity using the visual style information highly correlated with Content, Accuracy, and Ease of Use. Users were satisfied when they receive accurate, precise, and sufficient information. In addition, a user-friendly and simplified navigation interface improved the searching experience and stimulate users to further their searching activity. In contrast, the Format and Timeliness showed a weak correlation. Providing visual classification and appeal format has less impact on user satisfaction. In addition, the fast speed of information retrieval and up-to-date information showed an insignificant contribution to user satisfaction. Overall, this research demonstrated that information quality components, namely Content, Accuracy, and Ease of Use, influenced User Satisfaction when searching for games based on the visual style. Future studies should explore and evaluate the effectiveness of visual style information systems for digital game distribution platforms in Malaysia.

“…Making epidemiological indicators for COVID-19 publicly available can support public health experts in the near-real-time monitoring of the situation worldwide, and in the establishment of rapid response and public health measures to reduce the consequences of the pandemic. Moreover, making this information publicly available on a timely and consistent basis can impact the effective public engagement during an emergency or pandemic ( 14 – 16 ) which is a key aspect to ensure compliance of response/preventive measures needed to tackle the emergency or pandemic ( 17 – 19 ) and reduce misinformation/disinformation that can jeopardize the public health communication strategies.…”

IntroductionMaking epidemiological indicators for COVID-19 publicly available through websites and social media can support public health experts in the near-real-time monitoring of the situation worldwide, and in the establishment of rapid response and public health measures to reduce the consequences of the pandemic. Little is known, however, about the timeliness of such sources. Here, we assess the timeliness of official public COVID-19 sources for the WHO regions of Europe and Africa.MethodsWe monitored official websites and social media accounts for updates and calculated the time difference between daily updates on COVID-19 cases. We covered a time period of 52 days and a geographic range of 62 countries, 28 from the WHO African region and 34 from the WHO European region.ResultsThe most prevalent categories were social media updates only (no website reporting) in the WHO African region (32.7% of the 1,092 entries), and updates in both social media and websites in the WHO European region (51.9% of the 884 entries for EU/EEA countries, and 73.3% of the 884 entries for non-EU/EEA countries), showing an overall clear tendency in using social media as an official source to report on COVID-19 indicators. We further show that the time difference for each source group and geographical region were statistically significant in all WHO regions, indicating a tendency to focus on one of the two sources instead of using both as complementary sources.DiscussionPublic health communication via social media platforms has numerous benefits, but it is worthwhile to do it in combination with other, more traditional means of communication, such as websites or offline communication.
