Syntactic information, obtainable through syntactical analysis, plays an important role in many areas of NLP. Researches of Indonesian constituent parser have been very limited with the currently available yields very poor performance of 38.89% and 47.22% using Earley and CYK algorithm respectively. With the availability of the newly introduced Indonesian treebank corpus, we evaluate the performance of Indonesian constituent parser using Trance parser, a language independent constituent parser which employs deep learning. The parser achieved a respectable f-score of 74.91%, a very significant improvement to previous researches.
