I started jiu jitsu a few years ago. The fundamentals were constantly stressed. So, I spoke with a handful of blackbelts so they could clearly state the fundamentals to me. Unfortunately many of them couldn’t articulate them and only provided me with a vague idea. So I wanted to find a way to explicitly define the fundamentals of jiu jitsu, starting with the most foundational principle from which all others build upon.
To do this I scraped the social media profile of a jiu jitsu expert, John Danaher, because he is the most knowledgeable instructor on the planet and shares lessons daily on his social media accounts. I processed the data for some NLP analysis. The goal was to find the most informative posts then feed those posts to Google’s BERT algorithm for summarization.
To filter the posts I used lowered, lemmatized, and tokenized the words. Then I created a library with weights. I limited the library to the top 100 highest weighted words. I then scored each post based on the library. I then fed the highest rated posts to BERT to find a summary of jiu jitsu.
