Ebola: Can big data or semantic text help?
“Many problems” in this case Yes it can. We’ll get to to how big data or semantic meaning can help in a moment. First a few observations. As the Prof. Redlener, the NYT’s expert on disaster preparedness put it, “There are many, many problems that have been revealed by this single case.” This is a polite way for saying what at the Dallas hospital was a major screw-up that needlessly put lives in danger and unnecessarily forced additional people into a 21-day quarantine. We can talk about using semantic text technologies to prevent these kinds of hospital errors, or big data to improve traveler screening processes. At the end of the day, however, this is a type of error that the billing department at the Dallas hospital should have been able to catch. EbolaCare(TM) insurance “Where do we send this bill?” “Hmmm, address in Liberia. Looks like he has EbolaCare(TM), the national health plan of Liberia.”… Read the restError bands, or why models will be models (of the mathematical variety)
In response to our article on the Social Progress Index (SPI) and prediction markets, the Social Progress Index folks asked why we didn’t just stop at optimizing the SPI. Two reasons, we said: (1) There’s an unfortunate tendency of people to believe (math) models are reality. They’re just models with error bands. (2) There’s going to be politically-motivated suspicion of any model (as well as political-motivated attempts to manipulate models and their interpretation). [For our readers coming over from our fashion design section, or our earlier article on virtual reality fashion models and modeling, we are talking about mathematical models here.] So how do models go bad? Let’s use the Social Progress Index as an example. We talked elsewhere about the tension between things like freedom of press and national security in a model like this. (In general, such tension will exist in an useful economic or financial model. If the tension did not exist, there would be nothing interesting to optimize, and so need for such a model in the first place.)… Read the restMH17 and big data: preventing the tragedy?
This might be a good time to take a break from our usual Internet of Things and Predictive Analytics technological musings and take a quick look at current events. Can big data be applied to the tragic recent shoot-down of MH17? Could a country-scale analytics dashboard (or lessons derived from analytics) have prevented this tragedy? We think so. In an earlier blog article (before the tragedy), we discussed possible frameworks for country-wide analytics dashboards. For any such dashboards to be successful, it needs to be as apolitical as possible. For this to work, these models need first to be accepted by stakeholders (e.g., politicians, corporations, voters, citizens, tax-payers, oligarchs, dictators). There needs to be a general consensus that the models’ predictions are based on sound social science. Even if the models are not perfectly accurately, there should be an understanding that they are at least directionally correction in terms of connecting input parameters with future outputs.… Read the restContract product managers for start-ups?
“Would you consider hiring a contract product manager? [Part of our continuing Ask Acculation series; we originally answered this question on a Q&A site. Scroll down to the bottom of this post to find out how you can get your start-up, analytics, or business management questions answered in a future version of this column.] We know of companies that hire contract Product Managers (PMs). Our CEO has interviewed a number of PMs over the years and otherwise been involved in PM hiring decisions as well as worked with closely with many PMs while leading engineering and scientific teams. First off, we might want to take a step back and explain to readers what a product manager does. They’re typical managers or senior executives within a product division of a company. Not every firm considers itself a “product company” and so not every company has a product division or product managers. For example, a company that considered itself primarily focused on sales or financial investments might not have many product managers.… Read the restRecent Comments
