Resolution-Based Approximate Reasoning for OWL DL
We propose a new technique for approximate ABox reasoning with OWL DL ontologies. Essentially, we obtain substantially improved reasoning performance by disregarding non-Horn features of OWL DL. Our approach comes as a side-product of recent research results concerning a new transformation of OWL DL ontologies into negation-free disjunctive datalog [1, 2, 3, 4], and rests on the idea of perform...
متن کاملD-propranolol and DL-propranolol both decrease conversion of L-thyroxine to L-triiodothyronine.
The effects of propranolol (DL-propranolol) and D-propranolol on thyroid hormone metabolism were studied in six euthyroid volunteers receiving L-thyroxine (T4) and six hypothyroid patients receiving T4 replacement. D-propranolol as well as propranolol decreased L-triiodothyronine (T3) concentrations and the ratio of T3 to T4 in the euthyroid subjects, and D-propranolol decreased these variables...
متن کاملOptimising Resolution-Based Rewriting Algorithms for DL Ontologies
Resolution-based rewriting algorithms have been widely used for computing disjunctive datalog rewritings for DL TBoxes, and recently, also for computing datalog rewriting for queries over TBoxes expressed in DL-Lite and ELHI. Although such algorithms are general enough to support a wide variety of (even very complex) DLs, this generality comes with performance prices. In the current paper we pr...
متن کاملSLDR-DL: A Framework for SLD-Resolution with Deep Learning
This paper introduces an SLD-resolution technique based on deep learning. This technique enables neural networks to learn from old and successful resolution processes and to use learnt experiences to guide new resolution processes. An implementation of this technique is named SLDR-DL. It includes a Prolog library of deep feedforward neural networks and some essential functions of resolution. In...
متن کاملEffective thyroxine ratio and free thyroxine index
Brien, T. G., Fay, J. A., and Griffin, E. A. (1974). Archives of Disease in Childhood, 49, 225. Thyroid status in the newborn infant: effective thyroxine ratio and free thyroxine index. The effective thyroxine ratio (ETR) was determined in 28 term and 17 premature infants at birth and in 17 infants aged 0 to 6 weeks. The mean values found were significantly higher than those in 20 adult euthyro...
