A method of Chinese organization named entities recognition based on statistical word frequency, part of speech and length
We propose a recognition method based on statistics through analysis the grammatical and semantic characteristics of the Chinese organization name. This recognition method includes three elements: frequency, part of speech, word length. We use the data in mature collection as training data; separately calculate a candidate organization name's word frequency, part of speech and word length of the contribution. Finally get this candidate organization name's contribution, compare with a given threshold and achieve the recognition of a Chinese organization name.
Impact of Nuclear Data Uncertainties on Transmutation of Actinides in Accelerator-Driven Assemblies
Abstract The potential impact of nuclear data uncertainties on a large number of performance parameters of reactor cores dedicated to the transmutation of radioactive wastes is discussed. An uncertainty analysis has been performed based on sensitivity theory, which underlines the cross sections, the energy range, and the isotopes that are responsible for the most significant uncertainties. To provide guidelines on priorities for new evaluations or validation experiments, required accuracies on specific nuclear data have been derived, accounting for target accuracies on major design parameters. The required accuracies (mostly in the energy region below 20 MeV), in particular for minor actinide data, are of the same order of magnitude of the achieved accuracies on major actinides. Specific requirements also concern the improvement of minor actinide data related to decay heat and effective delayed-neutron fraction assessment.
