The Ape Bank of Cloud and big Data company how to transform the traditional examination item Bank product

Remember that classic case of big data mining? A store with a huge amount of information will even know that her daughter is pregnant before a mother. The product vision of the Ape test item is similar: In exams, it's better to know you than you are and to help you practice more efficiently. It will tell you which problem is not, where there is an omission, and if you practice hard enough, it can tell you how many points you can get in an exam that hasn't been held yet.

This is also the ape Question Bank CEO Li Yong stressed himself to do is actually large data business reasons. He said that the ape database is done through artificial intelligence algorithm for testing centers, test frequency and difficulty analysis, based on large data mining to accurately assess the user's current ability level, to achieve one-to-one targeted.

Yesterday on the line of the ape test questions-national judicial examination, is the Monkey test paper introduced the second exam item Bank class products. The previous ape question bank-the Civil Service exam series has attracted 200,000 of registered users in two months and is expected to reach 1.5 million this year. After the first attempt to the Community platform products Chalk Net, Li Yong Team choose from the qualification test for this small angle, once again into the online education.

"Unlike many educational websites, the ape bank does not simply want to move offline content to the line, but to bring computing and cloud services to traditional education." So we're actually a cloud computing company. There is no one to do this, but it is valuable. ”

Li Yong said: "Facts show that users of the Internet backed products to accept the intention is more optimistic than we think, cloud computing and data mining can play a big role in the behavior of Examinee can participate in product improvement, plus mobile Internet, this product development than expected a lot better. ”

Professional exam preparation is strong demand, users are active in the major sites and forums to find information, so the product is not difficult to contact the user, but the user is highly sensitive to product quality, so Li Yong Team's practice is, and traditional organizations to ensure the professional content, and then use data mining technology and user experience to build their own core value.

Li Yong said that in the traditional education methods, whether the test paper preparation or capacity testing, the establishment of the model when the method of assigning value is very rough, mainly by virtue of the teacher's experience, and it is difficult to optimize according to the performance of candidates. But for the ape item bank, it will be divided into two steps: when the product has just been rolled out and has not accumulated valid data, they will first take experience assignment, but with the accumulation of user data, they based on the project response theory, genetic algorithm, and Ebbinghaus memory curve established by the algorithm model will play a value, Make each user's Test paper different.

Moreover, the traditional education data processing is a sample, and the ape question bank as long as has the user to carry on the practice, can begin to collect the data, all user behavior is the data source, once no longer needs the sample, the data value label is particularly big, may minimize the deviation. and from their civil service line survey products, the introduction of two months, the user cumulative effective answer number has exceeded 22.35 million.

These algorithms and data, from the product level, are embodied in the two main modules of the Ape Bank: Intelligent Exercise and competency assessment.

In the intelligent practice this piece, the ape question bank will consider from two angles: 1. Who is doing the problem? In combination with the user before the historical data, real-time assessment of personal ability; 2. What is the problem, according to the vast number of effective users to do the problem data, real-time statistics of the relevant information, including the answer time for each question, the correct rate, difficulty, error, difficulty, combined with the test site and the difficulty of the value of the requirements, select the topic.

Take the mock test paper, the Monkey Bank is not the practice of the questions in the question of random extraction combination, but the combination of genetic algorithms, there is a complex calculation process: The system first generated 100 sets of questions in the bank, and then 22 combinations, new students into 200 sets of topics, and then the test site and the original user practice for the standard, the topic of scoring, Remove the scoring low and keep 100 sets. After doing this 100 times, you will eventually generate a set of quiz papers for the user.

From the ability assessment, they will be based on the user's historical practice data to calculate the user's mastery of each test site, and then through the match with the previous focus of the examination, mapping to the actual test, the user in the actual possible score to predict. Conco, operations director, said that after the results of the civil servants ' provincial examinations this year, some user feedback said that the ape-question bank's predictions and the scores they actually scored differed within 5 minutes.

Because of the user's willingness to pay for educational products, and for the willingness of the team, the Apes select the monthly subscription fee, and the price of the division examination Bank and row test item Bank is 25 yuan per month, and all new users have 3 days full function free experience period. Li Yong said that the two-month civil service question Bank, paid users about 5%, this is not low.

"The way the value-added service reminds me of the SP, says it is free, but in fact this also charges that also charges, this way too low." So we'd rather opt for a paid subscription. ”

However, user fees are not the only way to profit from the apes since he defined himself as a big data company, Li Yong thought is still the data business, he said, the ape bank is a learning product, but positioning and education measurement, so will use the data available, try to work with educational institutions.

Although for different exams, the ape question Bank will provide the custom function, but the model already can reuse, the marginal cost is greatly reduced, therefore they will soon launch the different product for each kind of qualification examination, including the upcoming Test paper and the first class construction engineer question Bank which will release in June, including the qualification examination Question Bank also in the plan.

They seem to be clear enough about the way they want to go: The 30-person team, most of them technology developers, has plans to make ends meet in the second half of the year.
