Given a term (word) versus tweet (document) matrix, non-negative matrix factorization (NMF) can be used to pull out a preset number of topic vectors. This is, in concept, similar to singular-value decomposition (SVD) except that, unlike SVD, NMF keeps all elements of the resulting vectors as positive contributions, making the results easier to interpret. The topic vectors shown below are from the 700 original tweets at SDPain_2022 keeping the 396 words that occurred three or more times. For more on NMF and text mining, see "NMF - A visual explainer and Python Implementation" at https://bit.ly/3vv5skV and "Learning the parts of objects by non-negative matrix factorization" at
