    Building sentiment lexicons based on recommending services for the Polish language
    (Wydawnictwa AGH, 2016) Gliwa, Bogdan; Zygmunt, Anna; Dąbrowski, Michał
    Sentiment analysis has become a prominent area of research in computer science. It has numerous practical applications, e.g., evaluating customer satisfaction, identifying product promoters. Many methods employed in this task require language resources such as sentiment lexicons, which are unavailable for the Polish language. Such lexicons contain words annotated with their emotional polarization, but the manual creation of sentiment lexicons is very tedious. Therefore, this paper addresses this issue and describes a new method of building sentiment lexicons automatically based on recommending services. Next, the built lexicons were used in the task of sentiment classification.

    Hybrid neuro-fuzzy classifier based on NEFCLASS model
    (Wydawnictwa AGH, 2011) Gliwa, Bogdan; Byrski, Aleksander
    The paper presents hybrid neuro-fuzzy classifier, based on NEFCLASS model, which was modified. The presented classifier was compared to popular classifiers - neural networks and k-nearest neighbours. Efficiency of modifications in classifier was compared with methods used in original model NEFCLASS (learning methods). Accuracy of classifier was tested using 3 datasets from UCI Machine Learning Repository: iris, wine and breast cancer wis-consin. Moreover, influence of ensemble classification methods on classification accuracy was presented.
