Euler Input File Checker

This checker takes a plain text file which is going to be used as input of Euler, then checks whether it is a valid input file of Euler, including:

• Unmatched leaves:
  By convention every leaf concept should be aligned by an articulation in an alignment.
• Children with multiple parents:
  Usually each child concept has only one parent concept.
• Multiple roots per taxonomy:
  Mostly each taxonomy is a tree, so there is only one root.
