一个新的度量标准，词成熟度，估计的发展，由个别学生的知识，每个词在一个大型语料库。该指标是由潜在语义分析建模的单词知识作为一个功能的阅读，模拟学习者已经做了，并校准其发展的信息内容接近模拟识字成人。通过自适应测试，将个人学习者的知识与模拟相结合。证据的准确性，例如应用词汇评估，教学和阅读研究，性能的度量，并推测其可能更广泛的重要性。
A new metric, Word Maturity, estimates the development by individual students of knowledge of every word in a large corpus. The metric is constructed by Latent Semantic Analysis modeling of word knowledge as a function of the reading that a simulated learner has done and is calibrated by its developing closeness in information content to that of a simulated literate adult. Individual human learner knowledge is aligned with the simulation by adaptive testing. Evidence of accuracy, example applications to vocabulary assessment, teaching and reading research, properties of the metric, and a conjecture about its possible wider importance are described.
