Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0050] The purpose of the present invention is to quickly determine which of a group (hundreds to tens of thousands) of target expressions a certain text matches, and is usually used to determine in real time whether a certain document is related to that network event. Each event is marked by some user words and logical words, for example: the expression...

Abstract

The invention relates to the technical field of data mining, in particular to a data screening method and device and electronic equipment, and the method comprises the steps: obtaining at least one user expression which comprises user words and logic words; grammatical analysis is conducted on the user expression, and a tree-shaped data structure corresponding to the user expression is established; sequentially extracting user words in each tree-shaped data structure, matching the extracted user words with a target document, and determining a first target expression matched with the target document; and determining a second target expression matched with the target document according to the logic words in the first target expression. The method comprises the following steps: firstly, extracting user words in each user expression, screening in a target document, and determining which user words appear in the target document to determine a first target expression so as to reduce the subsequent matching quantity; and performing secondary screening on the first target expression based on the logic words to determine a second target expression matched with the target document, so that the data screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a data screening method, device and electronic equipment. Background technique [0002] In the data subscription business system, after users input search expressions, they often hope that the system can automatically push out relevant data. For example, the user enters a search expression of "Beijing AND weather", which is used to retrieve text related to Beijing's weather conditions. If the two words "Beijing" and "weather" appear in a document at the same time, the document matches the preceding expression. [0003] In the prior art, the keywords and the logical relationship of the keywords are generally extracted by analyzing the expressions input by the user, and then the documents are searched. However, when the user inputs many expressions at a time, if the data is filtered for each expression in turn, the filtering efficiency will be low. Contents of the invention...
