System requirements

• Insertion and retrieval of data has to be done quickly and easily

• Should be possible to export the data so it can be analyzed with other informatics

systems

• Should support statistical assessments

• Have user-friendly visualization capabilities

• Controlled access to data, based on user roles, accounting for data privacy issues

• Easy dissemination of related studies and results

• Always online (web-based)

• Help finding additional information about the microorganisms present in the biological

samples

1.635 lines x 137 columns

ProtoFilWW system major components

1. Content Management component: supports the

researchers managing and analyzing the data obtained

from the WWTP’s samples

2. Text Mining component: finding additional information

about the microorganisms present in the biological

samples

Major Text Mining technologies used

• Lucene is a high-performance text search engine

library.

• Solr is a standalone enterprise search server with a

REST-like API

• UIMA is a powerful infrastructure for the storage,

transport, and retrieval of document and annotation

knowledge accumulated in NLP pipeline systems

• LINNAEUS is a popular organism name identification

system for biomedical literature that is capable of

normalizing to unambiguous NCBI taxonomy identifiers

Preventive Medicine

Alert the user to the risk of Type 2 Diabetes.

How?

1. We know the user has a gene mutation associated with Type 2

Diabetes, because he gave us is genome!

2. We know what he has eaten, because he told us!

3. We know what exercise he’s been doing, because he told us!

4. Genehome connects the dots!
