The problem is that each document has a single species (or super-species, or sub-species), and needs to get information about it's place in the hierarchy 'elsewhere', i.e. in an externally encoded hierarchy.
I don't, for example, have data in this format: SPECIES: "Hordeum / Hordeum vulgare / Hordeum vulgare var. hybernum" but rather SPECIES: "Hordeum vulgare". How can I add in that data at analysis time? Cheers, Dan.
