Description

Agenda The following work is a prototype financed by the BMWi in the projects Smart Data Web and MACSS. This talk focusses on: Digitization: Insights from text and relational data Our Work: In-Data-Base-Text-Mining (INDREX) What‘s next? Learning to Join between Text and Relations

Why again Digitisation? Exclusive signals help us and our maschines optimizing our core business. 1. Live longer and healthier, maximize therapy adherence. 2. Understand what will your customer likely buy, now and tomorrow.

3. Given our understanding of our customer we optimize •

output for given human labor



natural resources consumption



technology development and usage … until “good enough”

These optimization may create cost savings in our organization.

Better: We sell a platform that enables these optimizations for our customers. Beuth Hochschule für Technik Berlin – Alexander Löser – www.datexis.com

Data-driven Product Examples We conduct BMWi projects (Smart Data Web, ExCELL and MACCS) and industry funded projects with our partners. Siemens SE, Zalando SE, ubermetrics GmbH: All about my brands, products, suppliers, competitors, acquisition targets … from blogs, forums, news, …. and please, fresh!

Charité, SAP SE: Interactive medical systems, such Patients diary, Anamnesis, all about me, correlate information with signals from medical systems SpringerNature: Return scientists condensed tables instead of force them to read publications We heard many more: fraud, CRM, call center support, due dilligence of M&A, legal information from the Web, … Image Sources: Brinki (http://www.flickr.com/photos/brinkmann/493590524/) [CC BY-SA 2.0] Heidelberger Life-Science Lab (Heidelberger Life-Science Lab) [CC BY-SA 3.0] Paul Goyette (http://www.flickr.com/photos/pgoyette/168076182/) [CC BY-SA 2.0 ]

The typical Data Science Process Data driven products implement an iterative process.

All about leads, brands, suppliers, patients, diseases…. Sample from raw data Iterate and resample

Data-driven product

Test model

Cleanse and recombine samples

Learn Model

Plattform: Distributions (IBM Big Insight, Cloudera, MAPR, Hortenworks), Main Memory Data Bases or Cloud Providers (AWS etc.)

INDREX leverages existing Language Models INDREX builds a universal relation on top of the DWH and text data. The single system benefits from built-in features of the RDBMS (columnar layout, security, views, optimizer, transactional behavior, main memory, …).

Shared Nothing + Shared Memory (from ´16) INDREX runs on the Shared Nothing RDBMS Cloudera IMPALA. From 2016 on we will work on a Shared Memory Implementation based on SAP HANA.

Entity Recognition with Deep Neural Networks

We develop character-based models for entity recognition with high recall unsupervised language models trained with word embeddings adaptive annotation using recursive neural networks (RNN) Beuth Hochschule für Technik Berlin – Alexander Löser – www.datexis.com

Take Away Message INDREX recombines text- with relational data in a single system and behind your firewall. The declarative approach is tested with SQL programmers with Cloudera, Zalando, Siemens or SpringerNature (and with Charité in 2016).

Further developments are: •





Shared Memory for the medical domain with SAP, DFKI and Charité Helper functions, such as dictionary learning, robust failuretolerant embeddings, batch and interactive joins Active learning of entity linkage and relations

Feel free to test! The INDREX prototype comes as virtual box (Cloudera CDH 5) and with a toy corpus.

Span Data Model supports RDBMS-optimizer We represent text data with the span data model. Moreover, we provide transformation functions from this model to the bag of word, sequence based, dependency-tree based and relational model.
