The invention discloses a knowledge point quantitative-
analysis method and device. The method includes: constructing a knowledge point lineage graph, and establishing correspondence relationships of all knowledge points and all test questions, wherein the knowledge point lineage graph includes a knowledge point meta-
database and a
test question database; positioning a to-be-checked knowledge pointin the knowledge point meta-
database, and acquiring at least one detection
test question, which corresponds to the to-be-checked knowledge point, in the
test question database according to the corresponding relationships; receiving an answering answer input by an examinee, acquiring a test
question answer of the detection test question in the test question database, and carrying out analysis andcomparison on the test
question answer and the answering answer to obtain
question answering result information of the examinee for the to-be-checked knowledge point; and determining mastery result information of the examinee on the to-be-checked knowledge point according to all the
question answering result information of the examinee. According to the knowledge point quantitative-analysis methodand device provided by the invention, the knowledge point can be quickly accurately and quantitatively analyzed, the mastery result information of the examinee on the knowledge point can be accurately determined, then examinee learning efficiency can be improved, and complete construction of a knowledge
system of a learner is effectively helped.
