Providing adaptive electronic reading support

摘要

A method may include estimating a current level of vocabulary knowledge of a learner. The method may also include determining a first vocabulary level of a first chunk in an electronic document read by the learner. Additionally, the method may include comparing the current level of vocabulary knowledge of the learner with the first vocabulary level of the first chunk. The method may further include determining whether to replace, in the electronic document, the first chunk with a second chunk of a vocabulary database based on the comparison of the current level with the first vocabulary level. The second chunk may have a second vocabulary level.
