Abstract: There is provided an association analysis method and apparatus. An original database is divided into projection databases, each not contributing to a support count of a frequent item set of another. The projection databases are used for sequential-pattern association analysis performed respectively by nodes corresponding to the projection databases. Local frequent item sets and corresponding support counts obtained by the nodes are combined. Since an established projection database does not contribute a support count of a frequent item set of another projection database, different nodes can perform association mining, including pruning, on different projection databases respectively.

Abstract: Disclosed is a method for investigating data, the method including: starting an investigation application program preinstalled on a mobile terminal, receiving an investigation request in a display interface of the investigation application program, and determining whether a corresponding initiator of the investigation request is a predetermined investigating role; receiving an assignment instruction to assign the investigation task when the corresponding initiator of the investigation request is the predetermined investigating role and a corresponding investigation task of the investigation request is a predetermined task; and performing a corresponding transfer or assignment of the investigation task after determining the investigation task needs to be transferred or assigned, when the corresponding initiator of the investigation request is the predetermined investigating role and the corresponding investigation task of the investigation request is not the predetermined task.

Abstract: The disclosed embodiments provide a method and an apparatus for acquiring an evaluation index. The method comprises the steps of inputting samples into a classification model for classification training and acquiring output data of the classification model; acquiring probability statistics by performing probability distribution on the output data, wherein the probability statistics comprise probability intervals and a number of true positive samples and a number of true negative samples in each probability interval; and calculating the evaluation index of the classification model according to a threshold set and the acquired probability statistics. In the disclosed embodiments, probability statistics is performed for the output data of the classification model; and the evaluation index is calculated based on the acquired probability statistics, thereby solving the problem of scanning output data multiple times during the calculation of evaluation index.

Abstract: The present disclosure discloses methods and apparatuses for distinguishing topics. One exemplary method for distinguishing topics includes: extracting data from data corresponding to known topics, marking the extracted data, and combining the marked data and data to be trained into a training data set; clustering the training data set to obtain topics to which training data belongs; and distinguishing, based on the marked data, whether a topic obtained by clustering is a known topic or a new topic. The methods and the apparatuses consistent with the present disclosure reduce the difference between human beings' understanding and machines' understanding of a question, and can increase the accuracy for identifying questions raised by users.

Abstract: Embodiments of the disclosure provide a text information clustering method and a text information clustering system. The method can include performing word segmentation on multiple pieces of text information to generate multiple words; performing an initial clustering on the multiple words to generate multiple first-level topics, each of the first-level topics comprising at least two pieces of text information; determining, for each of the first-level topics, a number of second-level topics based on a number of pieces of text information under the first-level topic; and performing, according to the number of second-level topics of each of the first-level topics, a secondary clustering on the multiple words of at least two pieces of text information comprised in the first-level topic to generate multiple second-level topics.

Abstract: The present disclosure provides a data processing method, including: receiving an expiration redemption file sent by a channel side and a mandatory redemption file sent by a third party system; when a verification of the expiration redemption file succeeds and the expiration redemption file is a closed one, judging whether redemption data contained in the expiration redemption file is identical with pre-stored purchase data; when the redemption data is identical with the pre-stored purchase data, and the mandatory redemption file requires full redemption on expiration, matching the expiration redemption file with the mandatory redemption file; and when the expiration redemption file is identical with the mandatory redemption file, generating a result confirmation file, informing the third party system, and sending the result confirmation file to the channel side.

Abstract: A method, device, terminal, and storage medium for amending prompt.
