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 be performed. Alternatively, word sense induction methods can be tested and compared within an application. For instance, it has been shown that word sense induction improves Web search result clustering by increasing the quality of result clusters and the degree diversification of result lists. It is hoped that unsupervised learning will overcome the knowledge acquisition bottleneck because they are not dependent on manual effort. Other approaches may vary differently in their methods: The knowledge acquisition bottleneck is perhaps the major impediment to solving the WSD problem. Unsupervised methods rely on knowledge about word senses, which is barely formulated in dictionaries
