Embodiment 1
[0040] figure 1 It is a schematic flowchart of a method for determining automatic retrieval keywords in an embodiment of the present invention. Such as figure 1 Shown, a kind of determination method of automatic retrieval keyword, described method comprises:
[0041] Step 110: Obtain the first keyword from the automatically retrieved document;
[0042]Specifically, enter the documents that need to be retrieved into the retrieval system for automatic keyword retrieval, and analyze the content of the target retrieval document through the system to obtain the keywords. As the first keyword, the first keyword can be the title The subject of the document, or the words that appear more frequently in the document, can also be the core effect expression words obtained through semantic analysis, etc.
[0043] Step 120: determining a first retrieval database according to the first keyword;
[0044] Further, the determining the first search database according to the first keyword inc...
Embodiment 2
[0074] Based on the same inventive concept as that of a method for determining an automatic retrieval keyword in the foregoing embodiment, the present invention also provides a device for determining an automatic retrieval keyword, such as figure 2 As shown, the device includes:
[0075] A first obtaining unit 11, the first obtaining unit 11 is configured to obtain a first keyword from an automatically retrieved document;
[0076] A first determining unit 12, configured to determine a first search database according to the first keyword;
[0077] A second determination unit 13, configured to determine a first document from the first retrieval database;
[0078] A first judging unit 14, configured to judge the similarity between the first document and the target retrieval document;
[0079] The second obtaining unit 15 is configured to obtain a second keyword from a first document when the similarity meets a predetermined condition, wherein the first keyword and the second k...
Embodiment 3
[0093] Based on the same inventive concept as the method for determining an automatic retrieval keyword in the foregoing embodiment, the present invention also provides a device for determining an automatic retrieval keyword, on which a computer program is stored, and when the program is executed by a processor, the foregoing A step in any method of the authentication method for network authority.
[0094] Among them, in image 3 In, bus architecture (represented by bus 300), bus 300 may include any number of interconnected buses and bridges, bus 300 will include one or more processors represented by processor 302 and various types of memory represented by memory 304 circuits linked together. The bus 300 may also link together various other circuits, such as peripherals, voltage regulators, and power management circuits, etc., which are well known in the art and thus will not be further described herein. The bus interface 306 provides an interface between the bus 300 and the...
