Online Entropy-Based Model of Lexical Category Acquisition

  title={Online Entropy-Based Model of Lexical Category Acquisition},
  author={Grzegorz Chrupala and Afra Alishahi},
Children learn a robust representation of lexical categories at a young age. We propose an incremental model of this process which efficiently groups words into lexical categories based on their local context using an information-theoretic criterion. We train our model on a corpus of childdirected speech from CHILDES and show that the model learns a fine-grained set of intuitive word categories. Furthermore, we propose a novel evaluation approach by comparing the efficiency of our induced… CONTINUE READING
