From: Explorative search of distributed bio-data to answer complex biomedical questions
Example of History Navigation Tree of a bio-data exploration through search services registered in Bio-SeCo. From an initial query (using the NCBI Blast service), three subsequent query expansion refinements (using the GPDW Protein coding Gene, Array Express gene expression search and GPDW Protein Genetic Disorder services, respectively); then one backward step (to the query expansion refinement using the Array Express gene expression search service, by undoing the query expansion refinement performed using the GPDW Protein Genetic Disorder service) and a following query expansion (using the GPDW Gene Biological Function Feature annotation service).
