WebMain Steps. The main steps are as follows: The questions have body and title. We make a consolidated column combining body and the title . We make a TF-IDF vector for each of the questions text column and also of the question asked by the student. We calculate the cosine similarity between the question asked and the consolidated list of questions. WebNov 30, 2024 · TF-IDF. A nifty trick for calculating the similarity between two strings is by applying TF-IDF not on the entire words, but on character n-grams to create vector representations. Then, we can use cosine similarity to calculate how similar strings are to each other and extract the best match!
