When trying to do information monitoring on any specific subject or public health surveillance in this case, we face a well known problem these days: Information overload and a lack of homogeneity in the sources of that information. Different standards are used, reports include different level of detail for the information and we have both event-based information and indicator-based reports.

Our approach with Riff is based on creating a platform that supports the collaboration of a cross-disciplinary team with machine-learning tools to aid them in finding patterns, trends or clusters in the information and fostering the exploration of hypothesis and feedback collection from the field. This way we get the best of the two worlds: Applied expertise and human intelligence in finding patterns, getting insights and even following hunches The processing power of machine-learning tools enabling the scanning and classification of huge amount of data As we’re faced with a cross-disciplinary problem (human, animal, environment, organisms, etc.) it becomes more clear that we need to offer a collaborative space for experts from multiple fields to work together on solving the problem.

1- Information get’s collected from different sources 2-Information get’s decorated with different layers of data, like remote sensing information about temperature, humidity or terrain. 3-Machine learning modules classify the articles in the system, determining location, name of diseases, symptoms or syndromes, extracting structured data like epidemiological numbers of suspected or confirm cases. 4-Experts from different disciplines collaborate around the information, creating comments, tagging, relating articles and correcting or training machine-learning algorithms. 5-Experts can use different visualizations and filtering tools, to explore the body of evidence as the event unfolds over time and space and create hypothesis of events that they can discuss or refine with their team members and decide whether they think that a field investigation is needed. 6-Field staff can collect and report information that gets incorporated back to the system.

To recap, The human experts interacting with automated systems The collaborative decision making environment I am sure one day soon we will have an EID impact assessment... just like there is an environmental impact assessment… Thank you VERY much for your time today…
