Mosquitoes are responsible for transfer of many vector-borne diseases. Dengue is one such viral infection that is transmitted by the Aedes mosquito. It is preventable but still the number of Dengue cases have risen 30-fold in the past 50 years. In several countries in south American continent and Asia, dengue is one of the leading causes of death. It is mainly found in tropical and sub-tropical regions, particularly surrounding urban and semi-urban areas.

Historically, there has been an intensive increase in the number of dengue cases from 2000-2010 and, if adequately explored, essential information can be retrieved. Thus, we decided to develop Dengue Spread Information System (DSIS), a geographic-health information system designed to highlight the spread of dengue cases in Iquitos, Peru, and San Juan, Puerto Rico from 1990 to 2013. The application is aimed at citizens, travelers, policymakers and researchers to analyze and interpret the change in risk factors leading to dengue outbreaks and  develop essential early warning applications and policies to counter future dengue outbreaks.

The application portrays an interactive map for the two cities with additional information about temperature and humidity. The application is accompanied by exploratory data analysis on several risk factors impacting Dengue spread which can aid and facilitate research in the domain so that Dengue spread can be prevented.

TWed Talk: Henrique Santos (TWC) on "Making Sense of Common Sense"
October 13, 2020

DESCRIPTION: The goals of commonsense reasoning systems include being able to answer commonsense reasoning questions. In order to compare systems, a number of benchmark question sets have arisen. Leaderboards have emerged to act as hubs for hosting benchmarks and supporting infrastructure that accepts submissions of commonsense reasoning systems that then get scored against the benchmarks. These benchmarks vary in structure. Some provide questions and answer choices, while others may provide factual observations and require reasoners to choose the most appropriate hypothesis to explain them. 

Recently, there is an increasing effort to incorporate structured knowledge in these systems, largely based on machine-learning techniques, as a way to improve their overall score against benchmarks. In this talk, we will present and discuss our current efforts in supporting this goal, in the context of the Machine Commonsense Project. It includes a Benchmark Ontology, which provides a common vocabulary to allow diverse benchmarks to be compared, integrated, and to support the analysis of systems and machine-learning language models. This talk will discuss its design decisions and showcases how it is currently supporting the development of a Benchmark tool.

Health INCITE COVID Summer Projects Final Review: COVID Twitter (20 Aug 2020)
August 20, 2020

In this exploratory study, we scrutinize a database of over 1 million tweets collected across the first five months of 2020 to draw conclusions about public attitudes towards the preventative measure of mask usage during the COVID-19 pandemic. In recent months, a body of literature has emerged to suggest the robustness of trends in online activity as proxies for the epidemiological and sociological impact of COVID-19. We employ natural language processing, clustering and sentiment analysis techniques to organize tweets relating to mask-wearing into high-level themes, then relay narratives for individual clusters through automatic text summarization.

We find that topic clustering and visualization based on mask-related Twitter data offers revealing insights into societal perceptions of COVID-19 and techniques for its prevention. We observe that the volume and polarity of mask related tweets has greatly increased. Importantly, the analysis pipeline presented can be leveraged by the health community for the assessment of public response to health interventions in the ongoing global health crisis.
