Fiscal illusion Mourao (2008) attempts to quantify fiscal illusion empirically for almost 70 democracies since 1960. Fiscal illusion Fiscal illusion is a public choice theory of government expenditure first developed by the Italian economist Amilcare Puviani in his 1903 book "Teoria della illusione finanziaria" ("Theory of Financial Illusion" (not yet translated into English, but translated into German in 1960 under the title "Die Illusionen in der öffentlichen Finanzwirtschaft", Berlin: Dunker & Humblot, 1960)). Fiscal illusion suggests that when government revenues are not completely transparent or are not fully perceived by taxpayers, then the cost of government is seen to be less than
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
