Finding circular attributes in attribute grammars
Journal of the ACM, 1999The problem of finding the circular attributes in an grammar is considered. Two algorithms are proposed: the first is polynomial but yields conservative results while the second is exact but is potentially expontial. It is also shown that finding the circular attributes is harder than testing circularity.

Attribute-Based Encryption for Range Attributes
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2016Attribute-Based Encryption ABE is an advanced form of public-key encryption where access control mechanisms based on attributes and policies are possible. In conventional ABE, attributes are specified as strings. However, there are certain applications where it is useful to specify attributes as numerical values and consider a predicate that determines

Selecting syntactic attributes for authorship attribution
The 2011 International Joint Conference on Neural Networks, 2011In this work we present a methodology to select syntactic attributes for authorship attribution. The approach takes into account a multi-objective genetic algorithm and a Support Vector Machine classifier and it operates in a wrapper mode. Through a series of comprehensive experiments on a database composed of 3000 short articles written in Portuguese ...

Estimates of frequency: Attribute or attribution?
Journal of Experimental Psychology: Learning, Memory, and Cognition, 1986Subjects in two experiments were asked to estimate how often items had appeared in a studied list. If the estimates are based on the value of a frequency attribute, the implicit question is, "How many times did you think of this item during study?" If, on the other hand, estimates are memorial attributions, the implicit question is, "How many study ...

Journal of Trauma and Acute Care Surgery, 2014
To improve quality, programs such as accountable care organizations need to determine the part of the health care system most "responsible" for a complication. This is referred to as attribution. This provides a framework to compare physicians for patients and third-party payers. Traditionally, the attribution of complications has been to the admitting

Proceedings of the 21st annual ACM symposium on User interface software and technology, 2008
Attribute gates are a new user interface element designed to address the problem of concurrently setting attributes and moving objects between territories on a digital tabletop. Motivated by the notion of task levels in activity theory, and crossing interfaces, attribute gates allow users to operationalize multiple subtasks in one smooth movement.

British Journal of Clinical Psychology, 1988
Subjects rated the importance of 24 different contributors towards overcoming four relatively common problems: alcoholism, depression, sexual problems and shyness. Factor analysis revealed seven almost identical clusters for each problem, which were labelled inner control, receiving help, understanding, social consequences, physical basis, avoidance ...

Proceedings of the 20th ACM international conference on Multimedia, 2012
This work presents a new interactive Content Based Image Retrieval (CBIR) scheme, termed Attribute Feedback (AF). Unlike traditional relevance feedback purely founded on low-level visual features, the Attribute Feedback system shapes users' information needs more precisely and quickly by collecting feedbacks on intermediate level semantic attributes ...

Graph attribution with multiple attribute grammers
ACM SIGPLAN Notices, 1987Attributed graphs are well suited to represent structured sets of data objects. A multiple attribute grammar (MTAG) consists of several attribute grammars that describe an attributed graph as a union of attributed trees. Thus, from an MTAG one can automatically generate attribute evaluators for graphs.

Behaviour, 1966
The instinct versus learning controversy once revived by LEHRMAN's critique of LORENZ's theory has subsided, yet the issue seems to remain unclear in the minds of many people (SCHOENFELD & BARON, 1965). Although neither the definition of instinct nor the criteria for the dichotomy have been formally put forth, ethologists characterized instinctive ...
