Hello friends, I am trying to check similarity of two documents or two sentances. I am using TF-IDF and cosine similarity check for this. But in some cases it does not work. for example "Train is delayed" and "Train is running late" these two sentances are similar but we only can recognize this, using cosine similarity algorithm we cannot get the required result. Is there any other similarity algorithm which will also work for such cases, or could any one help me on this case. Please help me on this.
