How people do relational reasoning? Role of problem complexity and domain familiarity

Shikhar Kumar, Iliano Cervesato, Cleotilde Gonzalez
2014 Computers in Human Behavior  
Literature in the field of psychology of human reasoning offer little insight as to how people solve relational problems.  ...  The goal of this paper is to study how people do relational reasoning, such as selecting the grade of all students in a class with GPA (Grade Point Average) greater than 3.5.  ...  However, little is known about how people do relational reasoning. Clearly some people are very good at it (e.g., database programmers). But how natural is it for the rest of us?  ...

Computing Multi-Relational Sufficient Statistics for Large Databases

Zhensong Qian, Oliver Schulte, Yan Sun
2014 Proceedings of the 23rd ACM International Conference on Conference on Information and Knowledge Management - CIKM '14  
Contingency table algebra is a new extension of relational algebra, that facilitates the efficient implementation of this Möbius virtual join operation.  ...  Databases contain information about which relationships do and do not hold among entities.  ...  The model also supports probabilistic reasoning for answering "what-if" queries about the probabilities of uncertain outcomes.  ...

Statistical Dependency Parsing in Korean: From Corpus Generation To Automatic Parsing

Jinho D. Choi, Martha Palmer
2011 Workshop on Statistical Parsing of Morphologically Rich Languages  
Second, we show how to extract useful features for dependency parsing from rich morphology in Korean. Once we build the dependency Treebank, any statistical parsing approach can be applied.  ...  We also test the impact of fine vs. coarse-grained morphologies on dependency parsing. With automatic morphological analysis, we achieve labeled attachment scores of 80% + .  ...  The reason we use outputs from two different systems is to compare the impact of fine vs. coarsegrained morphologies on dependency parsing in Korean.  ...

Towards a robust query optimizer

Brian Babcock, Surajit Chaudhuri
2005 Proceedings of the 2005 ACM SIGMOD international conference on Management of data - SIGMOD '05  
No statistics available. In some cases, it is possible that full join synopses will not be constructed for all relations in a query.  ...  For every relation S such that R has a foreign key to S, join the sample of R with the full relation S.  ...

SmartInt: Using Mined Attribute Dependencies to Integrate Fragmented Web Databases [article]

Ravi Gummadi, Anupam Khulbe, Aravind Kalavagattu, Sanil Salvi, Subbarao Kambhampati
2011 arXiv   pre-print
The standard way of reconstructing the entities will involve joining the tables.  ...  Given a query, our system uses the Approximate Functional Dependencies (AFDs) to piece together a tree of relevant tables to answer it.  ...  Direct (Naive) Join: The second and a seemingly more reasonable approach is joining the tables using whatever shared attribute(s) are available.  ...

Effects of the 2010 Affordable Care Act Dependent Care Provision on Military Participation Among Young Adults

Pinka Chatterji, Xiangshi Liu, Barış K. Yörük
2018 Eastern Economic Journal  
The findings indicate that the ACA dependent care provision is associated with statistically significant reduction in the likelihood that young adults have military health insurance.  ...  In this study, we test whether the Affordable Care Act's (ACA) dependent care provision is associated with young adults' propensity to be in the armed forces and to have military health insurance.  ...  In addition to the health and labor market-related outcomes that have been studied, the ACA dependent care provision also may have affected young adults' decisions about whether or not to serve in the  ...

2013 Journal of Information and Data Management  
In this work we explore statistical methods, namely multiple regression analysis, in order to predict three distinct join types execution times, comparing them with actual running times.  ...  One of the most critical operations in data processing is joining large data sets. This is one of the most expensive and hardest operations to optimize.  ...  Time (Secs.) 3000 1500 1500 0 0 Join Queries Join Queries Fig. 12.

The following study explored farmer attitudes to BVD control schemes in relation to advice networks and information sharing, shared aims and goals, motivation and benefits of membership, notions of BVD  ...  Over half of Orkney scheme members stated their reason for joining was for 'personal gain', as compared to more altruistic reasons such as the 'overall good' of the Island.  ...  With regard to Norfolk, reasons for joining the scheme differed. Farmers tended to join either because their vet had advised them or to solve an existing or known prior problem with BVD.  ...
