Google Play Store serves as a platform to host, download, and review android applications. Many researchers have explored the user review section and worked on approaches and solutions that would prove a more effective pipeline to enable developer feedback on application issues and praised features proving the section's abundance of information. This work uses this same data to attempt a novel use case of determining child unsafe apps on Google Play Store. User reviews are collected using a crawler and categorized for selected keywords relating to child, media, and India. Since Google Play Store does not provide a definitive number of downloads, this work attempts to mitigate this challenge by instead calculating the user density for an application. The user density helps establish the engagement users have with an application and is calculated by the difference in the timestamps of the most and least recent reviews divided by the sum of total reviews and its upvotes for an application. 60,620 reviews from 1,600 applications were extracted to validate the proposed concept. This concept has proved effective in recognizing applications that present child unsafe content while also offering a novel concept of calculating user density.
It is said that every adversity presents the opportunity to grow. The current pandemic is a lesson to all healthcare infrastructure stakeholders to look at existing setups with an open mind. This chapter's proposed solution offers technology assistance to manage patient data effectively and extends the hospital data management system's capability to predict the upcoming need for healthcare resources. Further, the authors intend to supplement the proposed solution with crowdsourcing to meet hospital demand and supply for unprecedented medical emergencies. The proposed approach would demonstrate its need in the current pandemic scenario and prepare the healthcare infrastructure with a more streamlined and cooperative approach than before.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
