A Survey on Ontology System in Semantic Web using Intelligent Techniques

B. Gladys Gnana Kiruba
2016 Indian Journal of Science and Technology  
Methods/Statistical Analysis: Information retrieval among the web is not quite easy as the data is big. Semantic web enables to search the content of web in ease.  ...  Objectives: The current study provides how the web data can be analysed effectively using some intelligent techniques.  ...  For this case, attributes are called many-valued attributes. Since Formal Concept analysis presents multivalued attributes this can be best used for the semantic web to express the domain knowledge.  ...

Revisiting residential self-selection issues: A life-oriented approach

Junyi Zhang
2014 Journal of Transport and Land Use  
In this context, a life-oriented approach becomes relevant, where residential and travel decisions are interdependent not only with each other, but also with other life domains as a part of general life  ...  From a policy perspective, the life-oriented approach suggests that successful transport and land use policies should be designed together with policies in other significantly relevant sectors (e.g., health  ...  Cross-sectional evidence I used data from the life choice survey described in Section 2.1.1.  ...

Empirical evidence for the existence and uses of metacognition in computer science problem solving

Jennifer Parham, Leo Gugerty, D. E. Stevenson
2010 Proceedings of the 41st ACM technical symposium on Computer science education - SIGCSE '10  
For the problem solved in this research, the students reveal a pattern in their interactions between metacognitive processes and the domain-specific strategies used to develop a program.  ...  This research uses verbal protocols from computer science students, and based on the analysis of their transcripts, empirical evidence supports metacognition as a significant role in computer science problem  ...  Let n represent the actual number of data values in each list. For example, x and y can hold up to 10 elements, but the two arrays may only contain 5 actual data values, i.e. n=5.  ...

Model-Based Debugging using Multiple Abstract Models [article]

Wolfgang Mayer, Markus Stumptner
2003 arXiv   pre-print
In particular, model-based diagnosis, together with an abstract interpretation based conflict detection mechanism is used to derive diagnoses, which correspond to possible faults in programs.  ...  Design information and partial specifications are applied to guide a model revision process, which allows for automatic detection and correction of structural faults.  ...  In this work, context and partition are used in the sense of points-to analysis or call graph construction [GDDC97] and represent an abstraction of the call site of a method.  ...
