Hi, I'm trying to replace pprter stemmer with an english lemmatizer in my analysis chain. Just wondering what is the recommended way of achieving this. I've come across few different implementation which are listed below;
Open NLP --> https://lucene.apache.org/solr/guide/7_5/language-analysis.html#opennlp- lemmatizer-filter https://opennlp.apache.org/docs/1.8.0/manual/opennlp.html#tools.lemmatizer KStem Filter --> https://lucene.apache.org/solr/guide/7_5/filter-descriptions.html#kstem-filter There are couple of third party libraries , but not sure if they are being maintained or compatible with the solr version i'm using (7.5). https://github.com/nicholasding/solr-lemmatizer https://github.com/bejean/solr-lemmatizer Currently, I'm looking for English only lemmatization. Also, I need to have the ability to update the lemma dictionary to add custom terms specific to our organization (not sure of kstem filter can do that). Any pointers will be appreciated. Regards, Shamik
