Informal Persian Universal Dependency Treebank (iPerUDT)

Informal Persian Universal Dependency Treebank, consisting of 3000 sentences and 54,904 tokens, is an open source collection of colloquial informal texts from Persian blogs. The corpus is annotated in CoNLL-U format within the Universal Dependencies scheme (Nivre et al., 2020).

The following Course-grained Universal Dependencies parts of speech tags (UPOS), and fine-grained language-specific parts of speech tags (XPOS) are used in this treebank.

We used the Universal Dependencies annotation scheme which produces syntactic analyses of sentences in terms of the dependency structures of dependency grammar, determined by the relation between a head and its dependents. The syntactic annotation consists of 42 dependency relations, including 32 universal and 10 language-specific relations (marked by *).
