A document can typically refer to a sentence or paragraph and a corpus is typically a collection of documents as a bag of words. So, in such cases its desirable to train your own model. 1. Soft cosine similarity is similar to cosine similarity but in addition considers the semantic relationship between the words through its vector representation. This uses an extractive summarization algorithm. That is, for each document, a corpus contains each words id and its frequency count in that document. Make a graph with sentences that are the vertices. Using the ratio parameter, you specify what The Term Frequency Inverse Document Frequency(TF-IDF) is also a bag-of-words model but unlike the regular corpus, TFIDF down weights tokens (words) that appears frequently across documents. Text summarization has a huge demand in this modern world. Automatic text summarization is the task of producing a text summary "from one or more texts, that conveys important information in the original text(s), and that is no longer than half of the original text(s) and usually, significantly less than that".
