A Gold Standard Dependency Treebank for Turkish
Proceedings of The 12th Language Resources and Evaluation Conference, European Language Resources Association" (2020), pp. 5156-5163
Preview abstract
We introduce TWT; a new treebank for Turkish which consists of web and Wikipedia sentences that are annotated for segmentation, morphology, part-of-speech and dependency relations. To date, it is the largest publicly available human-annotated morpho-syntactic Turkish treebank in terms of the annotated word count. It is also the first large Turkish dependency treebank that has a dedicated
Wikipedia section. We present the tagsets and the methodology that are used in annotating the treebank and also the results of the baseline experiments on Turkish dependency parsing with this treebank.

The Practical Challenges of Active Learning: A Case Study from Live Experimentation
Jean-François Kagy
ICML Workshop on Human In the Loop Learning (2019)
Preview abstract
We tested, in a production setting, the use of active learning for selecting text documents for human annotations used to train a Thai segmentation machine learning model. In our study, two concurrent annotated samples were constructed, one through random sampling of documents from a text corpus, and the other through model-based scoring and ranking of documents from the same corpus. We observed that several of the assumptions forming the basis of offline (simulated) evaluation largely failed in the live setting. We present these challenges and propose guidelines addressing each of them which can be used for the design of live experimentation of active learning, and more generally for the application of active learning in live settings.

A Syntactically Expressive Morphological Analyzer for Turkish
Proceedings of the 14th International Conference on Finite-State Methods and Natural Language Processing, Association for Computational Linguistics, Dresden, Germany (2019), pp. 65-75
Preview abstract
We present a broad coverage model of Turkish morphology and an open-source morphological analyzer that implements it. The model captures intricacies of Turkish morphology-syntax interface, thus could be used as a baseline that guides language model development. It introduces a novel fine part-of-speech tagset, a fine-grained affix inventory and represents morphotactics without zero-derivations. The morphological analyzer is freely available. It consists of modular reusable components of human-annotated gold standard lexicons, implements Turkish morphotactics as finite-state transducers using OpenFst and morphophonemic processes as Thrax grammars.

The aim of this document is to provide a list of dependency tags that are to be used for the Arabic dependency annotation task, with examples provided for each tag. The dependency representation is a simple description of the grammatical relationships in a sentence. It represents all sentence relations uniformly typed as dependency relations. The dependencies are all binary relations between a governor (also known the head) and a dependant (any complement of or modifier to the head).
