Representing "Just Invalid" Knowledge
نویسنده
چکیده
Data, information and knowledge are all represented in a single formalism as “items”. Items contain two types of acceptability measures that measure the invalidity of item instances. Objects are item building operators that also contain two types of acceptability measures. These acceptability measures define a graduated acceptability region for data, information and knowledge. This region represents ‘just invalid’ knowledge. A quantitative calculus estimates the extent to which a knowledge base may be expected to extend into this region as time passes. This calculus is simplified by the use of the unified knowledge representation. A single rule of knowledge decomposition simplifies the structure of the conceptual model. Expressions in this calculus are simplified if the knowledge has been decomposed.

Background and Objectives: Nowadays, the academic integrity suffers from invalid science. Researchers may use this bogus research and conduct their studies based on them, and present invalid findings. Identifying main factors which lead to junk science propagation can be important and this study aimed to determine factors which are affecting the propagation of junk science by using phenomenogra...
متن کاملFinding the optimal bayesian network given a constraint graph
Despite recent algorithmic improvements, learning the optimal structure of a Bayesian network fromdata is typically infeasible past a few dozen variables. Fortunately, domain knowledge can frequently be exploited to achieve dramatic computational savings, and in many cases domain knowledge can even make structure learning tractable. Several methods have previously been described for representin...
متن کاملStatic Analysis of XSLT Programs
XML is becoming the dominant standard for representing and exchanging data on the World Wide Web. The ability to transform and present data in XML is crucial and XSLT (Extensible Stylesheet Language Transformations) is the principal programming language that supports this activity. Methods for analysis of XSLT programs are currently an important open issue. In this paper, we discuss new methods...
متن کاملEmpirically grounding grounded cognition: The case of color
Grounded cognition theories hold that the neural states involved in experiencing objects play a direct functional role in representing and accessing object knowledge from memory. However, extant data marshaled to support this view are also consistent with an opposing view that perceptuo-motor activations occur only following access to knowledge from amodal memory systems. We provide novel discr...
متن کاملThe Advantages of Abstract Control Knowledge in Expert System Design
A poorly designed knicd edge base can be as cryptic as an arbitrary program and just as difficult to maintain. Representing control knowledge abstractly, separately from domain facts and relations, makes the design more transparent and explainable. A body of abstract control knowledge provides a generic framework for constructing knowledge bases for related problems in other domains and also pr...
