Summary
UD_Bulgarian-BTB is based on the HPSG-based BulTreeBank, created at the Institute of Information and Communication Technologies, Bulgarian Academy of Sciences. The original consists of 215,000 tokens (over 15,000 sentences).
All the texts were processed automatically at tokenization, morphological and chunk level. Then, the full syntactic analysis were perfomed manually by trained annotators.
Introduction
The UD_Bulgarian-BTB consists of 156 149 tokens (11,138 sentences). This subset of BulTreeBank excludes ellipses and some rare phenomena. The conversion was done semi-automatically by Kiril Simov, with the application of set of rules and constraints for result consistency.
The rest of the sentences will be converted for the next releases. The original version is freely available for research upon request.
