Hello. I want to perform morphological analysis with lttoolbox. I have as input a text file and I want to incorporate this file in the analyzer and get as output the analyzed text. my question is which module is responsible to receive each sentence and generate its analysis. Moreover, I need to use the Tagger to keep just one analysis for each word, so how can I proceed? Note: these modules will be incorporated in my program. Any help please!
