Let f1, . . . , fn ∈ k[t], where k is an arbitrary field. A necessary and sufficient condition for the two function fields k(t) and k(f1, . . . , fn) to be same is developed in terms of zero-dimensionality of an ideal in the bivariate polynomial ring k[s, t]. Since zero-dimensionality of such an ideal can be readily determined by a Gröbner basis computation, this gives an algorithm that determi...

In this paper we present CroNER, a named entity recognition and classification system for Croatian language based on supervised sequence labeling with conditional random fields (CRF). We use a rich set of lexical and gazetteer-based features and different methods for enforcing document-level label consistency. Extensive evaluation shows that our method achieves state-of-the-art results (MUC F1 ...

Assigning documents to related categories is critical task which is used for effective document retrieval. Automatic text classification is the process of assigning new text document to the predefined categories based on its content. In this paper, we implemented and performed comparison of Naïve Bayes and Centroid-based algorithms for effective document categorization of English language text....
