Abstract: Our objective is to estimate focusing target of learner for the purpose of providing appropriate personal learning information automatically that enforces learner|s knowledge acquisition. In order to detect the understanding states of other learners based on their utterances, the solution network is introduced, which represents answering steps of exercise and easiness of deriving them. Then, the calculation method of understanding the states of other learner in answering steps by using the solution network is proposed. By comparing the calculated understanding states of other learners with that of the learner, the learner|s focusing target is determined. The experimental result showed that our prototype system could detect the correct focusing targets of learners who could not derive the answer by themselves and needed other learners| advices.
