Deterministic Automata for Unordered Trees

Adrien Boiret, Vincent Hugot, Joachim Niehren, Ralf Treinen
2014 Electronic Proceedings in Theoretical Computer Science  
While the existing notions are well-investigated concerning expressiveness, they all lack a proper notion of determinism, which makes it difficult to distinguish subclasses of automata for which problems  ...  Automata for unordered unranked trees are relevant for defining schemas and queries for data trees in Json or Xml format.  ...  The cost of the class of Presburger formulae is the cost of its class of filters.  ...

Data Analysis and Result Computation (DARC) Algorithm for Tertiary Institutions

Abel U. Osagie
2013 IOSR Journal of Computer Engineering  
We introduce a Fortran algorithm for Data Analysis and Result Computation (DARC). The algorithm analyzes student data as well as computes examination results of all students in a department at once.  ...  That a comprehensive solution for use in many tertiary institutions is not yet common presents a unique opportunity for researchers to help shape the future of this technology.  ...  The rest of the article gave a review of some related work, discusses data preparation, computation and analysis of the computed results.  ...

Applying Machine Learning to Enhance Optimization Techniques for OWL Reasoning

Razieh Mehri, Volker Haarslev
2017 International Workshop on Description Logics  
Our approach presented in this paper applies machine learning to make the selection process more effective and removes the need for manual fine tuning.  ...  Many of the techniques rely on heuristics that have been manually fine tuned for achieving a good performance but might fail dramatically when encountering ontologies exhibiting unexpected design patterns  ...  Therefore, learning to apply the most proper order for variables while solving a SAT problem helps with the order of applying variables in semantic branching.  ...
