The BoK Matching Tool (BMT) allows to compare EO4GEO BoK-annotated resources with respect to knowledge and skills and visually discover (dis)similarities. Resources can be ranked according to best/worst match and detailed statistics can be seen for every individual match. BoK-annotated resources understood by BMT are any content created by any of the other tools in the EO4GEO tools ecosystem: an educational offer (CDT), a job offer (JOT), an occupational profile (OPT) or an annotated PDF file (BAT).
