Description
This workflow finds disease relevant to the query string via the following steps: 1. A user query: a list of terms or boolean query - look at the Apache Lucene project for all details. E.g.: (EZH2 OR "Enhancer of Zeste" +(mutation chromatin) -clinical); consider adding 'ProteinSynonymsToQuery' in front of the input if your query is a protein. 2. Retrieve documents: finds 'maximumNumberOfHits' relevant documents (abstract+title) based on query (the AIDA service inside is based on Apache's Lucene) 3. Discover proteins: extract proteins discovered in the set of relevant abstracts with a 'named entity recognizer' trained on genomic terms using a Bayesian approach; the AIDA service inside is based on LingPipe. This subworkflow also 'filters' false positives from the discovered protein by requiring a discovery has a valid UniProt ID. Martijn Schuemie's service to do that contains only human UniProt IDs, which is why this workflow only works for human proteins. 4. Link proteins to disease contained in the OMIM disease database (with a service from Japan that interrogates OMIM) Workflow by Marco Roos (AID = Adaptive Information Disclosure, University of Amsterdam; http://adaptivedisclosure.org) Text mining services by Sophia Katrenko and Edgar Meij (AID), and Martijn Schuemie (BioSemantics, Erasmus University Rotterdam). OMIM service from the Center for Information Biology and DNA Data Bank of Japan, National Institute of Genetics, director Hideaki Sugawara (see http://xml.nig.ac.jp) Changes to our original BioAID_DiseaseDiscovery workflow: * Use of Martijn Schuemie's synsets service to * provide uniprot ids to discovered proteins * filter false positive discoveries, only proteins with a uniprot id go through; this introduces some false negatives (e.g. discovered proteins with a name shorter than 3 characters) * solve a major issue with the original workflow where some false positives could contribute disproportionately to the number of discovered diseases * Counting of results in various ways.

This is our original disease discovery workflow. Please note that some false positives among 'proteins' extracted from abstracts can contribute disproportionately to the number of diseaeses retrieved from OMIM (e.g. a protein called 'tumor').
If you are mainly interested in human proteins, please use BioAID_DiseaseDiscovery_byHumanUniProt. This workflow filters false positives by a check against human UniProt IDs (using a service provided by Martijn Schuemie).
In other cases you may want to try the BioAID_DiseaseDisvcovery_count version, as with this you can check manually for false positives. Diseases are listed and counted per extracted protein. We discovered the weakness in our original workflow with this workflow.
I updated the original with a version that both filters using uniprot (v2: rat, human, mouse), and counts. The original workflow can still be found as version 1. I will delete the separate uniprot and count versions from myExperiment.
