Strange lemmatization result in r, textstem package

由 北城以北 提交于 2021-01-29 09:30:29
问题 I would like to get lemma "dive" from all possible forms of the word using textstem package in R. But when I used textstem package in r, the basic form becomes a very strange result. library(textstem) words<-c("dived", "diving", "dive") lemmatize_strings(words, dictionary = lexicon::hash_lemmas) [1] "dive" "dive" "diva" Here, I do not want "dive" as a result from a word "dive", instead I need to lemmatize the word "dive" into "dive", so it can be counted as the same word with other forms

问题 I would like someone to correct my understanding of how VADER scores text. I've read an explanation of this process here, however I cannot match the compound score of test sentences to Vader's output when recreating the process it describes. Lets say we have the sentence: "I like using VADER, its a fun tool to use" The words VADER picks up are 'like' (+1.5 score), and 'fun' (+2.3). According to the documentation, these values are summed (so +3.8), and then normalized to a range between 0 and

What is “Orthogonality”?

What does "orthogonality" mean when talking about programming languages? What are some examples of Orthogonality? C. Ross Orthogonality is the property that means "Changing A does not change B". An example of an orthogonal system would be a radio, where changing the station does not change the volume and vice-versa. A non-orthogonal system would be like a helicopter where changing the speed can change the direction. In programming languages this means that when you execute an instruction, nothing but that instruction happens (very important for debugging). There is also a specific meaning when
