Crowdsourcing in Language Classes Can Help Natural Language Processing

Abstract

One way of teaching grammar, namely morphology and syntax, is to visualize sentences as diagrams capturing relationships between words. Similarly, such relationships are captured in a more complex way in treebanks serving as key building stones in modern natural language processing. However, building them is very time consuming, thus we have been seeking for an alternative cheaper and faster way, like crowdsourcing. The purpose of our work is to explore possibility to get sentence diagrams produced by students and teachers. In our pilot study, the object language is Czech, where sentence diagrams are part of elementary school curriculum.
