The repository which contains our code for our EACL 2021 paper titled, "Cognition-aware Cognate Detection". This work was awarded a best paper honourable mention among the long papers during the conference.

We ask the following pertinent questions with this work:

“Can cognitive features be used to help the task of Cognate Detection?”

furthermore,

“Using gaze features collected on a small set of data points, can we predict the same features on a larger set of data points to alleviate the need for collecting gaze data?”

Automatic detection of cognates helps downstream NLP tasks of Machine Translation, Cross-lingual Information Retrieval, Computational Phylogenetics and Cross-lingual Named Entity Recognition. Previous approaches for the task of cognate detection use orthographic, phonetic and semantic similarity based features sets. In this paper, we propose a novel method for enriching the feature sets, with cognitive features extracted from human readers’ gaze behaviour. We collect gaze behaviour data for a small sample of cognates and show that extracted cognitive features help the task of cognate detection. However, gaze data collection and annotation is a costly task. We use the collected gaze behaviour data to predict cognitive features for a larger sample and show that predicted cognitive features, also, significantly improve the task performance. We report improvements of 10% with the collected gaze features, and 12% using the predicted gaze features, over the previously proposed approaches. Furthermore, we release the collected gaze behaviour data along with our code and cross-lingual models.
