update of udpipe

I’m happy to announce that the R package udpipe was updated recently on CRAN. CRAN now hosts version 0.8.3 of udpipe. The main features incorporated in the update include

• parallel NLP annotation across your CPU cores
• default models now use models trained on Universal Dependencies 2.4, allowing to do annotation in 64 languages, based on 94 treebanks from Universal Dependencies. We now have models built on afrikaans-afribooms, ancient_greek-perseus, ancient_greek-proiel, arabic-padt, armenian-armtdp, basque-bdt, belarusian-hse, bulgarian-btb, buryat-bdt, catalan-ancora, chinese-gsd, classical_chinese-kyoto, coptic-scriptorium, croatian-set, czech-cac, czech-cltt, czech-fictree, czech-pdt, danish-ddt, dutch-alpino, dutch-lassysmall, english-ewt, english-gum, english-lines, english-partut, estonian-edt, estonian-ewt, finnish-ftb, finnish-tdt, french-gsd, french-partut, french-sequoia, french-spoken, galician-ctg, galician-treegal, german-gsd, gothic-proiel, greek-gdt, hebrew-htb, hindi-hdtb, hungarian-szeged, indonesian-gsd, irish-idt, italian-isdt, italian-partut, italian-postwita, italian-vit, japanese-gsd, kazakh-ktb, korean-gsd, korean-kaist, kurmanji-mg, latin-ittb, latin-perseus, latin-proiel, latvian-lvtb, lithuanian-alksnis, lithuanian-hse, maltese-mudt, marathi-ufal, north_sami-giella, norwegian-bokmaal, norwegian-nynorsk, norwegian-nynorsklia, old_church_slavonic-proiel, old_french-srcmf, old_russian-torot, persian-seraji, polish-lfg, polish-pdb, polish-sz, portuguese-bosque, portuguese-br, portuguese-gsd, romanian-nonstandard, romanian-rrt, russian-gsd, russian-syntagrus, russian-taiga, sanskrit-ufal, serbian-set, slovak-snk, slovenian-ssj, slovenian-sst, spanish-ancora, spanish-gsd, swedish-lines, swedish-talbanken, tamil-ttb, telugu-mtg, turkish-imst, ukrainian-iu, upper_sorbian-ufal, urdu-udtb, uyghur-udt, vietnamese-vtb, wolof-wtb
• some fixes as indicated in the NEWS file

How does parallel NLP annotation looks like right now? Let’s do some annotation in French.

library(udpipe)
data("brussels_reviews", package = "udpipe")
x <- subset(brussels_reviews, language %in% "fr")
x <- data.frame(doc_id = x$id, text = x$feedback, stringsAsFactors = FALSE)
anno <- udpipe(x, "french-gsd", parallel.cores = 1, trace = 100)
anno <- udpipe(x, "french-gsd", parallel.cores = 4) ## this will be 4 times as fast if you have 4 CPU cores
View(anno)

Note that udpipe particularly works great in combination with the following R packages

• crfsuite for entity recognition (more docs here)
• textrank for text summarisation (more docs here)
• BTM for topic modelling on short texts (more docs here)
• ruimtehol for doing text classification, text recommendation and finding similaries between articles, sentences, words, bigrams, labels, tags, persons, websites, entities and entity relations (more docs here and here)

And nothing stops you from using R packages tm / tidytext / quanteda or text2vec alongside it!
