Treebank is an important resource for both research and application of natural language processing.For Vietnamese, we still lack such kind of corpora.This paper presents up-to-date results of a project for Vietnamese treebank construction.Since Vietnamese is an isolating language and has no word delimiter, there are many ambiguities in sentence analysis.We systematically applied a lot of linguistic techniques to handle such ambiguities.Annotators are supported by automaticlabeling tools and a tree-editor tool.Raw texts are extracted from Tuoi Tre (Youth), an online Vietnamese daily newspaper.The current annotation agreement is around 90 percent.
