HETA: Hadoop environment for text analysis

As a leading energy player, EDF (Électricité de France) actively works on new techniques to better understand customers' voice. In order to process unstructured and semi-structured massive text data, we have developed HETA, an application based on open source solutions which offers different text processing steps (document engineering, text analysis, clustering and visualization) on top of Hadoop. It is based on Mahout and uses sigma.js library for the visualization of the results as interactive graphs. HETA presents an ergonomic Web interface and is able to analyze any kind of unstructured (blog comments) and semi-structured (tweets, articles, etc.) massive text data. Being a modular and extensible application, HETA can be easily enhanced with the addition of advanced text mining methods.
