It summarizes the text based on graph-based centrality scoring of sentences. LexRank uses an IDF-modified cosine similarity score to improve the Pagerank score for document summarization. LexRank Algorithm is an unsupervised approach to summarization and is inspired by the PageRank algorithm. To read text document from a text file with location as ‘file’: parser = om_file(file, Tokenizer("english"))Īfter reading the text document in Sumy Text Parser, we can use several algorithms or methods to summarize the given text document. To read text document from a text string variable ‘document’: parser = om_string(document, Tokenizer("english")) To read text documents from string variable or file, we can use a PlainTextParser from the Sumy package.
