Problems solved by technology

[0010] However, when the existing minimum hash algorithm is used to cluster text information, it does not consider the importance of each word element in the text, so it may combine two elements that are not of interest to the public at the same time. Text information clustered together

Abstract

The invention discloses a method and a device for generating text fingerprint information. The method comprises the steps as follows: an initial feature vector of a text is extracted; a weighted value of at least one element in the initial feature vector is endowed with a multiple value of the minimum weighted value; the weighted values of the other elements are endowed with the minimum weighted value; the corresponding element is added to the initial feature vector according to the multiple to form a new feature vector; and the text fingerprint information is generated after minimum hash algorithm is carried out on the new feature vector. The method and the device for generating the text fingerprint information disclosed by the invention can improve the accuracy of fingerprint information, so that information clustering has a relatively excellent effect.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for generating fingerprint information. Background technique [0002] With the continuous development and popularization of Internet technology, the amount of information faced by users of text information such as news is increasing at an alarming rate, and the demand for conveniently obtaining text information of interest to them is becoming more and more urgent. [0003] Due to the rapid increase in the amount of text information, the text categories are becoming more and more refined, and have strong real-time characteristics, often updated quickly and with extremely short timeliness. Therefore, effective clustering of texts can be provided to different users or different applications. is very important. [0004] Clustering refers to the process of dividing a collection of physical or abstract objects into classes consisting of similar objects. A clu...
