Monetary Policy and Exchange Rate Volatility in a Small Open Economy

by Jordi Galí, Tommaso Monacelli , 2003
"... We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a tractable canonical system in domestic inflation and the output gap. We employ this framework to analyze the macroeconomic implications of three alternative rule-based p ..."

Extracting structured data from web pages

by Arvind Arasu - In ACM SIGMOD , 2003
"... Many web sites contain a large collection of “structured” web pages. These pages encode data from an underlying structured source, and are typically generated dynamically. An example of such a collection is the set of book pages in Amazon. There are two important characteristics of such a collection ..."

rules or training sets. Extracting structured data gives us greater querying power over the data and is useful in information integration systems. Most of the existing work on extracting structured data assumes significant human input, for example, in form of training examples of the data

Scalable Algorithms for Association Mining

by Mohammed J. Zaki - IEEE TRANSACTIONS ON KNOWLEDGE AND DATA ENGINEERING , 2000
"... Association rule discovery has emerged as an important problem in knowledge discovery and data mining. The association mining task consists of identifying the frequent itemsets, and then forming conditional implication rules among them. In this paper we present efficient algorithms for the discovery ..."

The Logic of Bunched Implications

by Peter W. O'Hearn, David J. Pym - BULLETIN OF SYMBOLIC LOGIC , 1999
"... We introduce a logic BI in which a multiplicative (or linear) and an additive (or intuitionistic) implication live side-by-side. The propositional version of BI arises from an analysis of the proof-theoretic relationship between conjunction and implication; it can be viewed as a merging of intuition ..."

Discovery of spatial association rules in geographic information databases

by Krzysztof Koperski, Jiawei Han , 1995
"... Abstract. Spatial data mining, i.e., discovery of interesting, implicit knowledge in spatial databases, is an important task for understanding and use of spatial data- and knowledge-bases. In this paper, an e cient method for mining strong spatial association rules in geographic information database ..."

International Journal "Information Theories & Applications " Vol.12 DIAGARA: AN INCREMENTAL ALGORITHM FOR INFERRING IMPLICATIVE RULES FROM EXAMPLES

by Xenia Naidenova
"... Abstract: An approach is proposed for inferring implicative logical rules from examples. The concept of a good diagnostic test for a given set of positive examples lies in the basis of this approach. The process of inferring good diagnostic tests is considered as a process of inductive common sense ..."

Words and rules

by Steven Pinker , 1999
"... The vast expressive power of language is made possible by two principles: the arbitrary soundmeaning pairing underlying words, and the discrete combinatorial system underlying grammar. These principles implicate distinct cognitive mechanisms: associative memory and symbolmanipulating rules. The dist ..."

An Economic Theory of GATT

by Kyle Bagwell, Robert W. Staiger - American Economic Review , 1999
"... for helpful comments. This paper was written while Staiger was a Fellow at the Center for Advanced Study in the Behavioral Sciences. Staiger is also grateful for financial support provided by the Despite the important role played by GATT in the world economy, economists have not developed a unified ..."

in which governments maximize national income as well as the possibility emphasized in leading political-economy models that governments are concerned with the distributional implications of their tariff choices. Using this general framework we establish that GATT's principles of reciprocity

Integrating association rule mining with relational database systems: Alternatives and implications

by Sunita Sarawagi, Shiby Thomas - Data Mining and Knowledge Discovery
"... Abstract. Data mining on large data warehouses is becoming increasingly important. In support of this trend, we consider a spectrum of architectural alternatives for coupling mining with database systems. These alternatives include: loose-coupling through a SQL cursor interface; encapsulation of a m ..."
Abstract - Cited by 146 (5 self) - Add to MetaCart
using Association rule mining as a case in point. We consider four options in SQL-92 and six options in SQL enhanced with object-relational extensions (SQL-OR). Our evaluation of the different architectural alternatives shows that from a performance perspective, the Cache option is superior, although

Accounting for the effects of accountability

by Jennifer S. Lerner, Philip E. Tetlock - Psychological Bulletin , 1999

It focuses on 4 issues: (a) What impact do various accountability ground rules have on thoughts, feelings, and action? (b) Under what conditions will ac ..."
