Hello Alexander,

Word embedding models, such as word2vec, and glove, are common approaches; where words represented with a numerical vector ( https://arxiv.org/pdf/1310.4546.pdf <https://arxiv.org/pdf/1310.4546.pdf>, https://code.google.com/archive/p/word2vec/ <https://code.google.com/archive/p/word2vec/>). When you have word embedding, you can do geometric computations based other vectors. A common approach is to compute the average embedding of all words in a phrase; You can check fasttext for this purpose.

Regards, Mohammad

However, the LSA approach only works for individual words and no phrases and it is IMHO too numerical because it doesn't consider semantics of participating words.
