The concepts of fiscal federalism are related to vertical and horizontal fiscal relations. The notions related to horizontal fiscal relations are related to regional imbalances and horizontal competition. Similarly the notions related to fiscal relations
Word-sense disambiguation supervised machine learning techniques. The 2000s saw supervised techniques reach a plateau in accuracy, and so attention has shifted to coarser-grained senses, domain adaptation, semi-supervised and unsupervised corpus-based systems, combinations of different methods, and the return of knowledge-based systems via graph-based methods. Still, supervised systems continue to perform best. One problem with word sense disambiguation is deciding what the senses are. In cases like the word "bass" above, at least some senses are obviously different. In other cases, however, the different senses can be closely related (one meaning being a metaphorical or metonymic extension of another), and in such cases
