We consider the notion of an isomorphism between two hyper BCI-algebras and obtain all of the hyper BCI-algebras of order 3. It is shown that there exist 14 proper hyper BCI-algebras and 5 proper weak hyper BCI-algebras of order 3 up to isomorphism. Finally, further study on the theory of hyper BCI-algebra and its related hyper structure and applications of our results in information sciences a...

This paper describes the classifier part of a named entity recogniser for Norwegian which uses memory-based learning to categorise proper names. Names are classified into one of the categories Person, Organisation, Location, Work, Event, or Other. We test the effect of using different features as input to the model, ranging from knowledge-poor features such as windows of inflected forms, to fea...
