description

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.

Enriched Text Documents Drug Lord El Chapo Captured in Mexico PUBLISHED DATE SOURCE Audit 2014/02/22 Wikipedia Add Property Although Guzman had long hidden successfully in remote areas of the Sierra Madre mountains, the arrested members of his security team told the military he had begun venturing out to Culiacan and the beach town of Mazatlan. A week prior to his capture, Guzman and Zambada were reported to have attended a family reunion in Sinaloa. The Mexican military followed the bodyguards tips to Guzmans ex-wifes house, but they had trouble ramming the steel-reinforced front door, which allowed Guzman to escape through a system of secret tunnels that connected six houses, eventually moving south to Mazatlan. He planned to stay a few days in Mazatlan to see his twin baby daughters before retreating to the mountains. On 22 February 2014, at around 6:40 a.m., Mexican authorities arrested Guzman at a hotel in a beach front area in Mazatlan, Sinaloa, following an operation by the Mexican Navy, with joint intelligence from the DEA and
