Fecha de publicación: 05/06/2014 Fuente: Wipo "BigData" A method and system for determining causality based on big data analysis are provided. The method comprises extracting a plurality of unstructured data elements from a plurality of unstructured big data sources; generating at least one signature for each of the plurality of unstructured data elements; identifying at least one common pattern within the signatures of the plurality of unstructured data elements; matching the at least one common pattern to at least one hypothesis by comparing at least one signature of the common pattern to at least one hypothesis; and determining the causality of the at least one common pattern based on the at least one hypothesis matching the at least one common pattern.
