Often adjacent to one another, but the discourse structure of film (see Figure 1), thus related event pairs are In film scenes, events are very densely distributed, We use window sizes 1, 2 and 3, and calculate narrative causality forĮach window size. In this paper, the notion of window size indicates how many eventsĪfter the current event are paired with the current event. Unseen event pairs are smoothed with frequency equal to 1. We obtain the frequency of every event and event pair for each Lord of the Rings: Fellowship of the Ring We use StanfordĬoreNLP 3.5.2 to tokenize, lemmatize, POS tag, dependency parse and Illustrating the potential tradeoff between getting good probabilityĮstimates for event co-occurrence when the same events are repeated Scene descriptions ranges from 2000 to 35000 words.
