Retrieval method of scientific and technological resources based on machine reading comprehension

Abstract

The invention discloses a scientific and technological resource retrieval method based on machine reading comprehension, which sequentially performs noise removal, Chinese text word segmentation, stop word removal and word vector processing of scientific and technological text on text; the processed text adopts TF-IDF of n-gram The text matching method, by calculating the word frequency TF, inverse text frequency IDF and word order information of words in the text, finally calculates the similarity score between the text and keywords, and then determines the relevant text; the matched text is read and understood by machine The method integrates the machine reading comprehension model into the retrieval model, and returns the retrieval results by understanding the content in the text. This retrieval method not only fully considers the frequency TF and inverse text frequency IDF of the words in the text, but also fully considers the order information of the words, and then fully understands the semantics of the text, achieves more accurate text matching, and increases the ability of the model to understand. The content in the text returns more accurate retrieval results and improves the user's retrieval efficiency.
