получаване на основна форма на дума?

Използвах JAWS, тъй като го намерих за по-добър от JWNL, проверете този код, за да намеря основа за него и да го разясня

Бих предложил да опитате да използвате алгоритъм на Porter stemmer вместо wordnet, можете да намерите реализации на повечето езици - включително java тук

Това трябва да ви донесе това, което искате
