While computational estimation of dificulty of words in the lexicon is useful in many edu- cational and assessment applications, the concept of scalar word dificulty and curent corpus-based methods for its estimation are inadequate. We propose a new paradigm called word meaning maturity which tracks the degre of knowledge of each word at dif- ferent stages of language learning. We pre- sent a computational algorithm for estimating word maturity, based on modeling language acquisition with Latent Semantic Analysis. We demonstrate that the resulting metric not only corelates well with external indicators, but captures deeper semantic efects in lan- guage. 1 Motivation It is no surprise that through stages of language learning, different words are learned at different times an...
