IDG NEWS SERVICE - Nov 5 - Ancestry.com is using Hadoop as the cornerstone of a new service that allows users to submit a sample of their DNA and then have Ancestry.com look for relatives. eHarmony uses the service to refine its process of matching its millions of members. Hadoop has excelled at comparing thousands of variables across millions of different entities. eHarmony customers fill out an extensive questionnaire, which helps to estimate the user's personality across 29 different dimensions. The system first uses algorithms to predict how happy two potential matches would be if they were married. eHarmony must also predict how attracted two potential people would be to one another. Gauging attractiveness between two people is where the use of big-data-styled machine learning comes in. The service keeps track of a wide range of additional variables of its members including distance. The farther apart two people are geographically, the less likely they are to pick one another from a list of candidates.
