Lumify ( is an open source platform for big data analysis and visualization, designed to help organizations derive actionable insights from the large volumes of diverse data flowing through their enterprise. Utilizing both Hadoop and Storm, it ingests and integrates virtually any kind of data, from unstructured text documents and structured datasets, to images and video. Several open source analytic tools (including Tika, OpenNLP, CLAVIN, OpenCV, and ElasticSearch) are used to enrich the data, increase its discoverability, and automatically uncover hidden connections. All information is stored in a secure graph database implemented on top of Accumulo to support cell-level security of all data and metadata elements. A modern, browser-based user interface enables analysts to explore and manipulate their data, discovering subtle relationships and drawing critical new insights. In addition to full-text search, geospatial mapping, and multimedia processing, Lumify features a powerful graph visualization supporting sophisticated link analysis and complex knowledge representation.

Charlie Greenbacker (, Director of Data Science at Altamira (, will provide an overview of Lumify and discuss how natural language processing (NLP) tools are used to enrich the text content of ingested data and automatically discover connections with other bits of information. Joe Ferner (, Senior Software Engineer at Altamira, will describe the creation of SecureGraph ( and how it supports authorizations, visibility strings, multivalued properties, and property metadata in a graph database.
