Are there any (opensource) tools that can help with automatic or semi-automatic mapping of keys and values in GEO metadata to concepts in an (medical) ontology?
All the metadata in GEO is based on free-text keys and values and I would like to convert this to something more machine readable based on concepts in a (medical) ontology.
Metadata like gender, organism and tissue are often presents for different studies but also often named differently. For instance gender can be called gender or sex and the values might be M/F or Male/Female, While this all means the same.
Google and Wikipedia bring me to this page and to this demo for free text
The metadata I get from GEO is not free text but already in a table. Are there tools aimed at biology research that can convert a table with free text column keys and values to something more machine readable based on extracted concepts?
Lets say for example this table:
age sex Treatment Responder
individual1 10 M Aspirin Responder
individual2 22 M Aspirin Responder
individual3 45 F Ibuprofen nonresponder
