Abstract

The invention discloses a method for evaluating the innovation degree of text information. The method for evaluating the innovation degree of the text information comprises the steps of performing word segmenting pre-processing on acquired text data, and training an LDA model by using preprocessed data to realize an industry-themed classification for distinguishing texts in different industries so as to enable a trained model to contain model files of keywords of each industry category; establishing a knowledge network composed of key knowledge and technical information extracted from the preprocessed data according to a time sequence, and continuously updating the knowledge network at regular time intervals; utilizing the preprocessed data sorted according to the time sequence to extract attribute information of each piece of literature, establishing a literature text structure network, and determining an innovation type of each piece of literature; using the trained LDA model to analyze which industry technology keywords or knowledge keywords in patent data belong to respectively, and combining the attribute information of the literature text structure network so as to constitute multidimensional indexes for the innovation degree evaluation.

Description

technical field [0001] The invention relates to a method for evaluating the innovation degree of text information. Background technique [0002] With the continuous progress and development of information technology, people can easily and quickly obtain a large number of documents to meet people's reading and learning needs. At present, the degree of innovation of various literatures cannot be accurately measured. [0003] For example, the degree of innovation of patents, etc., still relies on manpower for retrieval and analysis, which requires professional training for personnel, and the speed of personnel retrieval and evaluation of innovation degree is relatively slow and requires different levels of review and supplementary retrieval. Examiners are under great pressure and may delay the progress of the review, resulting in delays in authorization, and more re-examination and invalidation matters. [0004] In addition, when enterprises carry out innovation work, they us...
