Detect related sentences This question is related to "How to grow a list of related words based on initial keywords?"

In the previous question they attempt to get similar words to a given word. However, I am interested in knowing the possibility of doing it to sentences.

As I'm not familiar with this area, my questions are:

Is there a way to do this with sentences (without just considering words)?
What tools are available for it?
Word Mover’s Distance (WMD) is an algorithm for finding the distance between pairs of strings. It is based on word embeddings (e.g., word2vec) which encode the semantic meaning of words into dense vectors.


  The WMD distance measures the dissimilarity between two text documents as the minimum amount of distance that the embedded words of one document need to "travel" to reach the embedded words of another document.


For example:

The gensim package has a WMD implementation.
