1 Shuang Liang ● Southern Medical University Building a Knowledge Discovery System

2 The real act of discovery consists not in finding new lands but in seeing with new eyes - Marcel Proust Marcel Proust Eying a picture is better than seeing a thousand words

3 Uncover the hidden links Disease Symptom Gene Protein miRNA SM Drug TCM Data Knowledge Bioinformatics

4 Focus Data Mining Data Integration Platform Building Translational Research Mining Clinical  data, Sequence, Literature etc. Omics, Annotation, Literature, Structure, Medical records/images HT Analytical pipeline, database, algorithm, prediction/analytical tools Drug screening, TCM, Target ID, Diagnosis, Prognosis

5  NCBI - GEO  EBI – ArrayExpress  NextGen Sequencing  Connectivity Map  GWAS/SNP/aCGH HT data Literature Structure Others  KEGG  DrugBank  Locate  MGI  PubMed  iHOP  GO  OMIM  GenBank  Transfac  miRBase  InterPro  TarFisDock Data Sources
