Dependency Parse Tree Processing Library

Dependency TreeBanks

Tesnière introduced the dependency trees, structural order, the concept of dependency and applied his representation concepts in a variety of languages such as French, Greek, Russian, Italian, and so on. In structural order, syntactic relations are presented in a hierarchical manner as opposed to the linear order. He uses “stemmas” to reflect hierarchy.

Today, dependency grammars are divided into two. One study from the tradition that applies this distinction to the dependency grammar is the Prague Dependency Treebank (PDT) developed by the Prague School of Functional and Structural Linguistics. A famous example for the other school of thought that displays linear order is the Penn Treebank that functioned between the years of 1989-1996, containing seven million annotated texts from American English.

In 2005, The Stanford Dependencies developed for the parsing of the English language and to be used in NLP studies and in Stanford Dependency Parser. Stanford Dependencies were acknowledged as the standard for the dependency analyses of English. However, the Stanford Dependency parser could not reach an adequate accuracy when it was used with other dependency schemes. In the following years, the Universal Dependency Treebank (UDT) project pioneered to develop treebanks for languages other than English by transforming the Stanford dependencies into a more inclusive annotation scheme for a diverse set of languages.

The developments in the dependency treebanking made it clear that Turkish language needed a Treebank of its own. The first Turkish language dependency treebank is METU-Sabanci Turkish Treebank. This treebank used a corpus that consisted of 7,262 sentences and included morphological and syntactic annotations. In 2016, this tree-bank was revisited under the name of ITU-METU-Sabancı Treebank (IMST) to reduce the inconsistencies of its earlier version. They succeeded to reduce inconsistencies by applying a new annotation scheme. As a last step, The Bogazici-ITU-METU-Sabancı Treebank (BIMST) is updated as the same corpus. Having a linguistic team of three people, they created a new annotation scheme for IMST and manually re-annotated the data of 5.635 sentences while introducing new dependency relations that were not present in IMST.

How to read a string as get a sentence for DependencyTreebankSentence ?

Hello, I would like to ask that how can I read a string as a sentence in DependencyTreeBankSentence? So I mean how can do the same job as public Sentence(String sentence) method in DependencyTreeBankSentence type? Thanks in advance.

Dependency relations NUSBJ:OUTER and CSUBJ:OUTER are missing

Atis contains these tags, we need to update universalDependencyTypes and universalDependencyTags in UniversalDependencyRelation

AUX:Q tag missing

UD v2 introduced a new dependency tag for Turkish. This should be added to our tag list.

UD tag obl:npmod is missing

Dependency Tag obl:npmod does not exist in TurkishDependencyParser/src/main/java/DependencyParser/Universal/UniversalDependencyType.java
