Literary Exploratory Machine (LEM) is an open-access service provided by CLARIN, used to process literary texts in Polish in order to extract statistical information from them. Using the LEM application, users can process text data from many different files saved in various formats, employ lemmatization algorithms, identify parts of speech, characterize the verbs used in the text, create an ordered list of proper names, extract statistics from the corpus, disambiguate lexical meanings, determine hyperonyms and hyponyms, as well as perform a stylometric analysis: group the texts, determine the similarity between them, and analyze the results using various methods of visualization.
