Abstract
U ovom radu dan je pregled trenutno aktualnih metoda strojnog učenja za analizu tekstualnih dokumenata. Prikazane su sve faze prirodnog procesiranja jezika kao i različiti algoritmi za klasifikaciju kao što je logistička regresija, Naive Bayes te strojevi s potpornim vektorima. U svrhu demonstracije implementiran je sustav u kojemu korisnici razmjenjuju poruke u stvarnom vremenu pri ćemu se poruke klasificiraju kao pozitivne ili negativne. Pri implementaciji sustava koristio se Apache Spark za izvršavanja svih faza podatkovne pipe za obradu teksta, Node.js i Socket.io za razmjenu poruka u stvarnom vremenu, Apache Kafka za prosljeđivanje poruka sa Node servera na Spark platformu te Apache Cassandra za spremanje rezultata. Također je izvršena evaluacija preciznosti prethodno navedenih algoritama za klasifikaciju pri kojoj su se koristili testni podatci. Poruke se uspješno klasificiraju te prikazana je jednostavna vizualizacija klasificiranih poruka.
Abstract (english)
This paper provides an overview of current machine learning methods for textual document analysis. All phases of natural language processing are presented as well as various classification algorithms such as logistic regression, Naive Bayes and support vector machines. For the purpose of demonstration, a system has been implemented in which users exchanges messages in real time, whereby messages are classified as positive or negative. The system was implemented using Apache Spark to execute all phases of natural languge processing pipeline, Node.js and Socket.io for real-time messaging, Apache Kafka for forwarding messages from the Node server to the Spark platform and Apache Cassandra for saving results. An evaluation of the accuracy of the aforementioned classification algorithms using test data was also performed. Messages are successfully classified and a simple visualization of classified messages is shown.
