A method and a device for automatic retrieval

[0055] Example one

[0056] figure 1 It is a schematic flowchart of an automatic retrieval method in an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0057] Step 110: Obtain a target search document, where the target search document includes a first search term.

[0058] Specifically, obtaining a target retrieval document is a target document that requires similar technologies to be retrieved, and the target retrieval document has some key information, such as retrieval terms, technical fields, classification numbers, and so on. The target search document includes a first search term, where the first search term is a key word of the core technology of the target search document.

[0059] Step 120: Obtain a first search database according to the first search term.

[0060] Step 130: Obtain the first extended word from the first search database according to the first rule.

[0061] Further, the first extended word and the first search word are simila

[0095] Based on the same inventive concept as the automatic retrieval method in the foregoing embodiment, the present invention also provides an automatic retrieval device, such as figure 2 As shown, the device includes:

[0096] The first obtaining unit is configured to obtain a target search document, where the target search document includes a first search term;

[0097] The second obtaining unit is configured to obtain the first search database according to the first search term;

[0098] The third obtaining unit is configured to obtain the first extended word from the first search database according to the first rule;

[0099] A fourth obtaining unit, configured to obtain a second search database according to the first expanded word;

[0100] The fifth obtaining unit is configured to obtain a target database according to the second search database and the first search database.

[0101] Further, the third obtaining unit includes:

[0102] The sixth obtaining unit is c

[0122] Based on the same inventive concept as the automatic retrieval method in the foregoing embodiment, the present invention also provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, the automatic retrieval method described above is realized. Steps of any method of the retrieval method.

[0123] Among them, in image 3 In the bus architecture (represented by the bus 300), the bus 300 can include any number of interconnected buses and bridges. The bus 300 will include one or more processors represented by the processor 302 and various types of memory represented by the memory 304. The circuits are linked together. The bus 300 may also link various other circuits such as peripheral devices, voltage regulators, power management circuits, etc., which are all known in the art, and therefore, no further descriptions thereof are provided herein. The bus interface 306 provides an interface betwe
