Stopwords: Topic modelling con LDA
...como stopwords? ¿Hay alguna forma de refinar más el
análisis y que haya más diferencias entre topics?
Este es el código que estoy usando:
Reviews_dtm <-text_df12star %>%
unnest_tokens(word, text) %>%
anti_join(stop_words)%>%
count(Brand, word) %>%
cast_dtm(Brand, word, n)
Reviews_lda <- LDA(Reviews12_dtm, k = 15, control = list(seed = 2016))
Un saludo
Miriam
