Recommandation Engine - small improvement

Sometimes the Smart Lexicon's strength can appear as a weakness to the average user, when it comes to words that have multiples lemmas.

Example on "hôtel" (screenshot). The user may think that we are not lemmatizing correctly, and cannot guess that the other "spellings" are in fact refering to creative works.

I suggest filtering these words in the recommandation engine. Maybe hide words which have the exact same lemma but with a very high specificity?
