A similarity measurement method for science and technology project text

Abstract： Existing text similarity measurements often use the TF-IDF method to model texts as term frequency vectors without considering the structural features of texts. This paper combines the structural features of texts with the TF-IDF method and proposes a text similarity measurement for science and technology project texts. This approach firstly pre-processes a text and extracts module texts according to its structural features. After applying the TF-IDF method to these extracted module texts, this method extracts the top keywords of each module text, obtains its feature vector representation, and finally uses cosine formula to calculate the similarity of two texts. By comparing with the TF-IDF method, experimental results show that the proposed method can promote the evaluation metrics of F-measure.
