This example is a quick exercise to illustrate the lemma results for a specific word or set of words.
A "lemma" is defined in Wikipedia as:
In morphology and lexicography, a lemma (plural lemmas or lemmata) is the canonical form, dictionary form, or citation form of a set of words (headword)[citation needed]. In English, for example, run, runs, ran and running are forms of the same lexeme, with run as the lemma.If we were to do this really thoroughly, the database contains the usage of the words as well. For example in the word above, "run" is used as a verb. However, "run" can also be a noun -- a baseball player scored a run; a Broadway show had a good run. That refinement might be available in a future release.
