awk -F "\"*,\"*" '{print $2}' DDID.csv | grep -v "DOID" > DDID.txt
awk -F "\"*,\"*" '{print $2}' GAMUTS.csv > GAMUTS.txt

This two steps created two txt file which contains the preferred terms. Then we can use the build function to create two list for further Acora algorithm.

The build function turned the txt file into a list, and filter out empty string and useless numbers.

We use the Acora module, which is based on the Aho-Corasick algorithm.yu
