It is assumed you have a word based likelihood table (csv file) where
the headers consists of the literal word ``Word`` and the remaining
columns are the features you would like to classify.

For example:

+----------+----------+---------+---------+
| Word | Animal | Human | Plant |
+----------+----------+---------+---------+
| cat | 0.33 | 0.03 | 0.05 |
+----------+----------+---------+---------+
| dog | 0.33 | 0.02 | 0.05 |
+----------+----------+---------+---------+
| leaves | 0.05 | 0.03 | 0.4 |
+----------+----------+---------+---------+
| tree | 0.05 | 0.02 | 0.4 |
+----------+----------+---------+---------+
| man | 0.12 | 0.45 | 0.05 |
+----------+----------+---------+---------+
| women | 0.12 | 0.45 | 0.05 |
+----------+----------+---------+---------+
