Hello Raimon, depending on what focus your master thesis should be Lucene / Solr may or not be the right project. Basically if your sentiment analysis topic is tight to information retrieval (very dummy example: making a search engine which scores documents boosting "positive" ones) then it could be ok (in this case you could leverage some classification capabilities Lucene has [1]) otherwise if your task is more focused on the extraction of such sentiments then other projects may fit better, see for example OpenNLP or Mahout or UIMA.
