Tokens are surface tokens (Spanish `vámonos` is one), words are syntactic words (`vamos` + `nos`); multiword tokens are those split into several words; empty nodes are the `N.M` nodes of the enhanced graph. Splits dev are absent from the release.

## Summary

> UD Indonesian-CSUI is a conversion from an Indonesian constituency treebank in the Penn Treebank format named [**Kethu**](https://github.com/ialfina/kethu) that was also a conversion from a constituency treebank built by [**Dinakaramani et al. (2015)**](https://github.com/famrashel/idn-treebank). We named this treebank **Indonesian-CSUI**, since all the three versions of the treebanks were built at Faculty of Computer Science, Universitas Indonesia.

## Introduction

> UD Indonesian-CSUI treebank was converted automatically from the [**Kethu**](https://github.com/ialfina/kethu) treebank, an Indonesian constituency treebank in the Penn Treebank format. The Kethu treebank itself was converted from a consituency treebank built by [**Dinakaramani et al. (2015)**](https://github.com/famrashel/idn-treebank).
> 
> Other characteristics of the treebank:
> 
> - Genre: news in formal Indonesian (the majority is economic news)
> - This treebank consists of 1030 sentences and 28K words. We divide CSUI treebank into testing and training dataset: Testing dataset consists of around 10K words Training dataset consists of around 18K words
> - Average sentence length is around 27.4 words per-sentence, which is very high compare to the [Indonesian-PUD](https://github.com/UniversalDependencies/UD_Indonesian-PUD) treebank that has average sentence length of 19.4.
