Monitoring Indonesian online news for COVID-19 event detection using deep learning

Even though coronavirus disease 2019 (COVID-19) vaccination has been done, preparedness for the possibility of the next outbreak wave is still needed with new mutations and virus variants. A near real-time surveillance system is required to provide the stakeholders, especially the public, to act in a timely response. Due to the hierarchical structure, epidemic reporting is usually slow particularly when passing jurisdictional borders. This condition could lead to time gaps for public awareness of new and emerging events of infectious diseases. Online news is a potential source for COVID-19 monitoring because it reports almost every infectious disease incident globally. However, the news does not report only about COVID-19 events, but also various information related to COVID-19 topics such as the economic impact, health tips, and others. We developed a framework for online news monitoring and applied sentence classification for news titles using deep learning to distinguish between COVID-19 events and non-event news. The classification results showed that the fine-tuned bidirectional encoder representations from transformers (BERT) trained with Bahasa Indonesia achieved the highest performance (accuracy: 95.16%, precision: 94.71%, recall: 94.32%, F1-score: 94.51%). Interestingly, our framework was able to identify news that reports the new COVID strain from the United Kingdom (UK) as an event news, 13 days before the Indonesian officials closed the border for foreigners

Using Semantic Technologies in Digital Libraries- A Roadmap to Quality Evaluation

Abstract. In digital libraries semantic techniques are often deployed to reduce the expensive manual overhead for indexing documents, maintaining metadata, or caching for future search. However, using such techniques may cause a decrease in a collection’s quality due to their statistical nature. Since data quality is a major concern in digital libraries, it is important to be able to measure the (loss of) quality of metadata automatically generated by semantic techniques. In this paper we present a user study based on a typical semantic technique use

Digital Atlas of Tactics to Designing Sustainable Factories

For a long time, the design of factories has been profit-driven only, while their detrimental effects on the environment, perceptual-aesthetic interferences with the surroundings, and social disturbances on local communities have been largely neglected. Despite a growing attention towards these topics, literature shows that there is a fundamental knowledge and tool gap on design practices for holistically sustainable factories, and companies are often unaware of both negative and positive effects related to the impact of their sites on the landscape. This paper presents a toolkit that has been developed to support entrepreneurs and designers in devising more sustainable factories through an integrated perspective, which is the great novelty of the approach. The article focuses on one of its tools: a digital atlas of design tactics. These have been mapped in sustainable factories around the world and labelled with an ad hoc faceted classification. Each tactic is then described in an info-sheet, which feeds a web portal. There, the user is assisted in searching for the most suitable tactics and mutual links with other useful strategies. The main potentiality of the atlas is to encourage a holistic design approach by highlighting positive synergies among tactics from different field

Searching for Non-English Web Content: An Empirical Study of the Spanish Business Intelligence Portal

As non-English-speaking online populations grow rapidly, there are increasing needs to support searching for non-English Web content. Prior research has assumed English to be the primary language for Web searching, but this is not the case for many non-English-speaking regions. For example, Latin America will have the fastest growing population in the coming decades but existing Spanish search engines lack search, browse, and analysis capabilities. In this paper, we have proposed a language-independent approach to supporting non-English Web searching. Based on the approach, we have developed the Spanish Business Intelligence Portal (SBizPort) to support searching, browsing, summarization, categorization, and visualization of Web information. Results from an empirical study involving Spanish subjects show that the portal achieved significantly better user ratings on information quality, cross-regional search capability, and overall satisfaction than the benchmark search portal. This study thus contributes to human-computer interaction research on non-English Web searching

Tsunami-Related Data: A Review of Available Repositories Used in Scientific Literature

Various organizations and institutions store large volumes of tsunami-related data, whose availability and quality should benefit society, as it improves decision making before the tsunami occurrence, during the tsunami impact, and when coping with the aftermath. However, the existing digital ecosystem surrounding tsunami research prevents us from extracting the maximum benefit from our research investments. The main objective of this study is to explore the field of data repositories providing secondary data associated with tsunami research and analyze the current situation. We analyze the mutual interconnections of references in scientific studies published in the Web of Science database, governmental bodies, commercial organizations, and research agencies. A set of criteria was used to evaluate content and searchability. We identified 60 data repositories with records used in tsunami research. The heterogeneity of data formats, deactivated or nonfunctional web pages, the generality of data repositories, or poor dataset arrangement represent the most significant weak points. We outline the potential contribution of ontology engineering as an example of computer science methods that enable improvements in tsunami-related data management

Effective dashboards for urban water security monitoring and evaluation

This paper reviews the factors affecting effective dashboards for urban water security monitoring and evaluation. Urban water security is a constantly evolving field influenced by several factors, including changes in climate, ecosystems, socio-economic status, and human beings. Although urban water security has been discussed in some parts of the literature, there has been minimal literature review that focused on the factors of urban water security and the effective dashboards for monitoring and evaluation. Using systematic literature review (SLR) and preferred reporting items for systematic reviews and meta-analysis (PRISMA), this paper reviewed 143 articles. The result shows growth in the environmental informatics landscape since the last ten years when the first article on the urban water management dashboard was published. The visual design was the most frequently discussed factor for dashboards, followed by user customization. It also shows that this topic can go deeper to integrate both factors and design an effective environmental dashboard. The discussion identified three potential opportunities for future research in water security and informatics: i) exploring other dimensions of effective dashboards, ii) considering more research on the environmental dashboard, and iii) investigating the real-life application of dashboards in urban water security
