Embodiment Construction
[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0058] Such as figure 1 As shown, the text selection device provided by the present invention includes: according to the needs of specific types of scientific and technological texts, the selected preprocessed feature sample set, professional thesaurus, and corpus; based on the objective scoring module of the text and the fuzzy scoring module of the text And the correlation scoring module between the text and the sample set; the BP neural network model used for screening. The establishment plan of the device is: take out the sample set in the file server and score it through each scoring module, and whether each score and the text are marked as optional (1 means selected, 0 means not selected), the most training Sample set, set training parameters according to different requirements, and obtain a BP neural network model that can be screened through feedback ...

The invention proposes a scientific and technical text selection method and apparatus, and belongs to the field of computer text analysis and mining. The apparatus provided by embodiments of the invention comprises a selected feature sample set, a calculation module which performs feature grading on texts in the sample set and comprises a text-based objective grading module, a text-based fuzzy grading module and a text and sample set association degree grading module, and a neural network screening model obtained through establishing a training set of whether various grades and texts are marked to be optional or not for training, wherein the text-based fuzzy grading module comprises text specialized vocabulary fuzzy grading, text key sentence pattern determination and grading, and text language objectivity grading. For to-be-selected texts, the selection method comprises the steps of performing various feature grading on the texts and performing screening through the trained neural network model. The method and the apparatus also can be used for evaluation selection of other various professional documents with certain features or establishment of an evaluation selection system.
Description
technical field [0001] The invention relates to the fields of intelligent expert systems and text mining analysis, in particular to a method and device for selecting scientific and technological texts. Background technique [0002] In recent years, my country has paid more and more attention to industry-university-research cooperation and encouraged scientific research institutions to transfer as many achievements as possible. Enterprises are also more and more willing to cooperate with scientific research institutions to jointly develop new technologies and create new value. In the process of cooperation, the communication between enterprises and scientific research institutions often begins with the submission of technical documents by enterprises to scientific research institutions. As an effective carrier of enterprise demand information, technical documents vary in quality due to the different technical expertise of each enterprise, and a technical document often invol...
