Ontology has been extensively applied in various fields, such as artificial intelligence, information extraction and retrieval \textit{et al}. In this paper we describe a new approach for automatic learning terminological ontology. The method takes the topics generated by generative topic model as concepts and builds subsumption relationships between such concepts to learn ontology without the existence...
Generally speaking, it is assumed that the smaller the size of the FDTD (finite difference time domain) cell, the better the result will be. In this communication, we show that the shape of the computational domain can significantly influence the accuracy of the results in the FDTD simulation. Specifically, an improper choice for the domain shape can dramatically degrade the FDTD results even if we...
