Hello, I am now preparing for Chinese text mining using jiebaR, in Korea on Korean language Windows OS.
Followings are my computing environment verified by library(jiebaR); sessionInfo().

library(jiebaR); sessionInfo();
R version 4.1.1 (2021-08-10)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 10 x64 (build 19042)

I managed to set up the word segmentation process as the following. The result, however, is disappointing in that user-defined dictionary doesn't work.

bri_text<-readLines("BRIVA_revised3.txt", encoding="UTF-8")

bri_stnc<-bri_text %>% as_tibble() %>% unnest_tokens(input=value, output=sentence, token="sentences")
bri_stnc<-bri_stnc %>% mutate(sentence_id=row_number())
bri_df<-bri_stnc %>%mutate(text=sapply(segment(bri_stnc$sentence, worker(bylines=TRUE, user= "C:/Users/user/Documents/R/win-library/4.1/jiebaRD/dict/user.dict.utf8")), function(x){paste(x, collapse=" ")})) %>% unnest_tokens(word, text)
bri_df

A tibble: 4,175 x 3

The problem is that there is no difference between with user-defined dictionary and without. Tibble structure of "4175 by 3" does not change even with user.dict. By the way, I checked out that stopwords.dict works well. I have no idea of what seems toi be the problem
For reference, I attach screen capture of "use.dict.utf8" file below.
Thanks for advise!
