Looks like it's from the description of the content of the film with the selection according to certain rules:
1. full descriptive action
2. descriptive type of character,
3. all of the emotional characteristics or actions
4. proper names, place names, etc.
5. all combinations of object/action that contains any word: "woman, man, name, motive, villain, hero, actor, origin" (etc.).
Word forms (p. 5) is likely to be a GENERAL table of nouns on the basis of the descriptions of ALL the films, occurring most frequently in the descriptions of all these movies put together. (ie, automatically generated tagging)
Also, I think that made addition in manual mode all the original word forms for the maximum required build interesting for the reader the thematic groups (tag/node).
