Embodiment Construction

[0027] The solution of the embodiment of the present invention is mainly: collect the text set with designated keywords, and screen out the text list corresponding to its mainstream meaning for ambiguous keywords; generate predetermined ambiguous keyword vectors and texts based on the text set Vector; calculate the similarity between the text vector and the predetermined ambiguous keyword vector, and filter out the text vector whose similarity is less than a predetermined threshold according to the similarity, so as to filter out the articles corresponding to the mainstream meaning of the ambiguous keyword required by the user.

[0028] Such as figure 1 As shown, a preferred embodiment of the present invention proposes a text filtering method based on ambiguous keywords, including:

[0029] Step S101, collecting text sets with designated keywords;

[0030] In this embodiment, based on the ambiguity TAG, the text list corresponding to the mainstream meaning is screened out, an...

Abstract

The invention discloses a polysemy keyword based text filtering method and device. The polysemy keyword based text filtering method comprises collecting a text set with an appointed keyword; generating into predetermine polysemy keyword vectors and text vectors based on the text set, wherein the predetermine polysemy keyword comprises the appointed keyword; calculating the similarity between the text vectors and the predetermine polysemy keyword vectors; filtering out texts of the text vectors with the similarity less than a predetermined threshold value. According to the polysemy keyword based text filtering method, a text list which is corresponding to the mainstream meaning is screened out based on the polysemy tag, then the used required texts are screened, the costs are low, the efficiency is high, the filtering efficiency is good, manual interference is not needed, and all polysemy keywords are applicable.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a text filtering method and device based on ambiguous keywords. Background technique [0002] Many words often have more than one meaning, and the primary meaning can vary in different contexts.
