Patent text classification method and device

Abstract

The invention provides a patent text classification method and device, and the method comprises the steps: obtaining a to-be-classified patent text, and extracting the patent attribute features of theto-be-classified patent text; performing word segmentation processing and word vector construction processing on the patent text to be classified to obtain text word vector features; inputting the patent attribute features and the text word vector features into a patent text classification model to obtain a classification result of the to-be-classified patent text according to operation of the patent text classification model, wherein the patent text classification model is a neural network model constructed by combining a classification information set corresponding to a preset technical classification node according to a preset training sample. Through a neural network learning mode, the patent text classification work is realized according to the technical classification nodes established by the technical system of the user and based on the patent text classification model trained by the classification information set constructed by the technical classification nodes, and the technical problem of low patent text classification efficiency in the prior art is solved.

Description

technical field [0001] The present application relates to the field of text classification, in particular to a patented text classification method and device. Background technique [0002] With the current vigorous development of intellectual property rights in our country, in order to better protect their own interests, many enterprises have begun to attach importance to the operation of intellectual property rights. Moreover, for technical enterprises, patent texts are an effective way to understand and master industry technologies. It also helps to provide direction guidance for technology research and development. For this purpose, many companies will choose to build their own patent database based on their own technology system for use. [0003] However, patent texts are different from ordinary texts in that they express very strong technical and legal characteristics, and have many additional attributes, such as classification numbers, applicants, etc. It is very compl...
