The method can be executed by a mining device or electronic device for subject words. The device or electronic device can be implemented by software and / or hardware. The device Or the electronic device can be integrated in any smart device with network communication function. Such as figure 1 As shown, the method for mining keywords may include the following steps:

[0056] S101. Receive a query word input by a user, and obtain at least one original topic word corresponding to the query word from a predetermined topic map.

[0057] In a specific embodiment of the present invention, the electronic device may receive a query word input by a user, and obtain at least one original topic word corresponding to the query word from a predetermined topic map. Specifically, the electronic device can first generalize the query words input by the user. ...

Embodiment 2

[0065] figure 2 It is a schematic flowchart of the method for mining subject words provided in Embodiment 2 of the present invention. Such as figure 2 As shown, the method for mining keywords may include the following steps:

[0066] S201. Receive a query word input by a user, and obtain at least one original topic word corresponding to the query word from a predetermined topic map.

[0067] In a specific embodiment of the present invention, the electronic device may receive a query word input by a user, and obtain at least one original topic word corresponding to the query word from a predetermined topic map. Specifically, the electronic device can first generalize the query words input by the user. Data generalization is an analysis process that abstracts and summarizes a large amount of task-related data in the database from a relatively low-level concept to a higher-level concept. The query words entered by the user are generalized to obtain multiple generalized words...

Abstract

The embodiment of the invention discloses a topic word mining method and device, an electronic device and a storage medium. The method comprises the following steps of receiving a query word inputted by a user, and obtaining at least one original topic word corresponding to the query word in a predetermined topic map; determining a basic information material recall set corresponding to all original theme words through a theme discrimination model in all pre-acquired information materials matched with the query words, wherein the basic information material recall set comprises at least one basic information material; in the basic information material recall set, mining the target topic word recall sets corresponding to all original topic words, wherein the target topic word recall set comprises at least one target topic word. According to the present invention, more topic words with higher writing value can be mined, so that a user can be helped to quickly select an appropriate focus point, and a more excellent article can be created within the shortest time.

Description
