Learn the mark that topic carries out knowledge point/examination point, it is follow-up it is all examine feelings, learn feelings, religion feelings be based on the label of the survey system into
Capable.However there are following defects for the mode of this handmarking：
1, the mark rule that expert manually carries out can not standardize.There is the understanding of mathematical problem inclined in each teacher expert
Difference, the label situation that also may result in different expert's labels have differences, and the difference of these marked differences can directly shadow
Ring the accuracy of matching and sequence.
2, the mark rule particle that expert manually carries out is spent slightly.That is, the mode of expert's mark can not include one
The comprehensive information of problem, and then influence the accuracy of matching and sequence.The information of artificial mark missing is including but not limited to as follows
It is several：The relationship between examination point and knowledge point can not be presented；The relationship between examination point and examination point in topic can not be presented, such as greatly
Examination point includes the inclusion relation of small examination point, the precedence relationship that examination point A and examination point B are one in front and one in back investigated；It can omit non-heavy in examination paper
Point but necessary being and it is possible that the examination point that students' union makes a mistake；And the calculation amount for the examination paper that can not withdraw deposit.And this mode
So that student can not carry out mistake because of positioning.If a problem does wrong, it can only judge that the corresponding all examination points of this problem are not all grasped,
Can not know it is which specific small examination point of this problem or general knowledge point are not grasped again, i.e., can not know the real of smallest particles degree
It is wrong because.
3, expert manually carry out mark human cost it is excessive.In general, can only be by there is the religion of 3 years or more teaching and research experiences
Teacher is marked, and could keep basic accuracy rate, and the teacher to lack experience is difficult the label of complete control mathematical problem.
4, it is helpless to student and understands topic.Student still can only see that the parsing to topic is just learned in the answer parsing of text,
However the parsing content of this text type is unfavorable for student's rational learning mathematical knowledge or even some students can be weary of and see text
Parsing.
5, the relationship between the natural language of topic and examination point can not be established.Due to topic natural language only and knowledge point
Related and examination point without direct relation, do not support artificial intelligence Direct Recognition topic in this way and solve the preposition of topic
Condition-data accumulation (the pass between the natural language for needing accumulation to segment and corresponding knowledge point and knowledge point and knowledge point
Coefficient evidence).
