Dravidian language family through Universal Dependencies lens
Taraka Rama, Sowmya Vajjala
The Universal Dependencies (UD) project aims to create a cross-linguistically consistent dependency annotation for multiple languages, to facilitate multilingual NLP. It currently…
What do complexity measures measure? Correlating and validating corpus-based measures of morphological complexity
Çağrı Çöltekin, Taraka Rama
We present an analysis of eight measures used for quantifying morphological complexity of natural languages. The measures we study are corpus-based measures of morphological comple…
Are pre-trained text representations useful for multilingual and multi-dimensional language proficiency modeling?
Taraka Rama, Sowmya Vajjala
Development of language proficiency models for non-native learners has been an active area of interest in NLP research for the past few years. Although language proficiency is mult…
Probing Multilingual BERT for Genetic and Typological Signals
Taraka Rama, Lisa Beinborn, Steffen Eger
We probe the layers in multilingual BERT (mBERT) for phylogenetic and geographic language signals across 100 languages and compute language distances based on the mBERT representat…
Tübingen-Oslo system: Linear regression works the best at Predicting Current and Future Psychological Health from Childhood Essays in the CLPsych 2018 Shared Task
Çağrı Çöltekin, Taraka Rama
This paper describes our efforts in predicting current and future psychological health from childhood essays within the scope of the CLPsych-2018 Shared Task. We experimented with…
Three tree priors and five datasets: A study of the effect of tree priors in Indo-European phylogenetics
Taraka Rama
The age of the root of the Indo-European language family has received much attention since the application of Bayesian phylogenetic methods by Gray and Atkinson(2003). The root age…
Experiments with Universal CEFR Classification
Sowmya Vajjala, Taraka Rama
The Common European Framework of Reference (CEFR) guidelines describe language proficiency of learners on a scale of 6 levels. While the description of CEFR guidelines is generic a…
Are Automatic Methods for Cognate Detection Good Enough for Phylogenetic Reconstruction in Historical Linguistics?
Taraka Rama, Johann-Mattis List, Johannes Wahle +1
We evaluate the performance of state-of-the-art algorithms for automatic cognate detection by comparing how useful automatically inferred cognates are for the task of phylogenetic…
Fast and unsupervised methods for multilingual cognate clustering
Taraka Rama, Johannes Wahle, Pavel Sofroniev +1
In this paper we explore the use of unsupervised methods for detecting cognates in multilingual word lists. We use online EM to train sound segment similarity weights for computing…
Chinese Restaurant Process for cognate clustering: A threshold free approach
Taraka Rama
In this paper, we introduce a threshold free approach, motivated from Chinese Restaurant Process, for the purpose of cognate clustering. We show that our approach yields similar re…
Siamese convolutional networks based on phonetic features for cognate identification
Taraka Rama
In this paper, we explore the use of convolutional networks (ConvNets) for the purpose of cognate identification. We compare our architecture with binary classifiers based on strin…
Empirical Evaluation of Tree distances for Parser Evaluation
Taraka Rama
In this empirical study, I compare various tree distance measures -- originally developed in computational biology for the purpose of tree comparison -- for the purpose of parser e…
Gap-weighted subsequences for automatic cognate identification and phylogenetic inference
Taraka Rama
In this paper, we describe the problem of cognate identification and its relation to phylogenetic inference. We introduce subsequence based features for discriminating cognates fro…
Does Syntactic Knowledge help English-Hindi SMT?
Taraka Rama, Karthik Gali, Avinesh PVS
In this paper we explore various parameter settings of the state-of-art Statistical Machine Translation system to improve the quality of the translation for a `distant' language pa…
Properties of phoneme N -grams across the world's language families
Taraka Rama, Lars Borin
In this article, we investigate the properties of phoneme N-grams across half of the world's languages. We investigate if the sizes of three different N-gram distributions of the w…
