Hi All Doug Turnbull's latest blog http://opensourceconnections.com/blog/2017/11/21/solr-synonyms-mea-culpa/ at OpenSourceConnections is great, I learned lots. He mentions Wordnet the lexical database for the English language. If you are using his suggested synonyms in Solr to 'tune' tf/idf then your synonym file will have synonyms for hypernyms (correct me if I got this wrong). Does it make any sense to import the hypernym records from Wordnet in bulk? Thanks -- Rick -- Sorry for being brief. Alternate email is rickleir at yahoo dot com
