# RDRPOSTagger

R package to perform Parts of Speech tagging and morphological tagging based on the Ripple Down Rules-based Part-Of-Speech Tagger (RDRPOS) available at https://github.com/datquocnguyen/RDRPOSTagger. RDRPOSTagger supports pre-trained POS tagging models for 45 languages.

The R package allows you to perform 3 types of tagging.

- **UniversalPOS** annotation where a reduced Part of Speech and globally used tagset which is consistent across languages is used to assign words with a certain label. This type of tagging is available for the following languages: **Ancient_Greek, Ancient_Greek-PROIEL, Arabic, Basque, Belarusian, Bulgarian, Catalan, Chinese, Coptic, Croatian, Czech, Czech-CAC, Czech-CLTT, Danish, Dutch, Dutch-LassySmall, English, English-LinES, English-ParTUT, Estonian, Finnish, Finnish-FTB, French, French-ParTUT, French-Sequoia, Galician, Galician-TreeGal, German, Gothic, Greek, Hebrew, Hindi, Hungarian, Indonesian, Irish, Italian, Italian-ParTUT, Japanese, Korean, Latin, Latin-ITTB, Latin-PROIEL, Latvian, Lithuanian, Norwegian-Bokmaal, Norwegian-Nynorsk, Old_Church_Slavonic, Persian, Polish, Portuguese, Portuguese-BR, Romanian, Russian, Russian-SynTagRus, Slovak, Slovenian, Slovenian-SST, Spanish, Spanish-AnCora, Swedish, Swedish-LinES, Tamil, Turkish, Urdu, Vietnamese**. 
- **POS** for doing Parts of Speech annotation based on an extended language/treebank-specific POS tagset. for This type of tagging is available for the following languages: **English, French, German, Hindi, Italian, Thai, Vietnamese**
- **MORPH** with very detailed morphological annotation. This type of tagging is available for the following languages: **Bulgarian, Czech, Dutch, French, German, Portuguese, Spanish, Swedish**

This is based on corpora collected and made available at http://universaldependencies.org.

## Examples on Parts of Speech tagging

The following shows how to use the package

```()
library(RDRPOSTagger)
models <- rdr_available_models()
models$MORPH$language
models$POS$language
models$UniversalPOS$language

x <- c("Oleg Borisovich Kulik is a Ukrainian-born Russian performance artist")
tagger <- rdr_model(language = "English", annotation = "POS")
rdr_pos(tagger, x = x)

x <- c("Dus godvermehoeren met pus in alle puisten, zei die schele van Van Bukburg.", 
       "Er was toen dat liedje van tietenkonttieten kont tieten kontkontkont",
       "  ", "", NA)
tagger <- rdr_model(language = "Dutch", annotation = "MORPH")
rdr_pos(tagger, x = x)

tagger <- rdr_model(language = "Dutch", annotation = "UniversalPOS")
rdr_pos(tagger, x = x)
```

The output of the POS tagging shows the following elements:
```
 doc_id token_id            token   pos
     d1        1              Dus   ADV
