Abstract

The invention relates to the technical field of sequence sampling, in particular to a sample representativeness calculation method for sequence sampling. The method comprises the steps of calculatinga span ratio, calculating a sampling ratio, calculating a sequence entropy and calculating representativeness. Various elements are comprehensively considered, and the representativeness of samplingsequences is reflected from the span, the sampling proportion and the distribution uniformity degree of sampling sub-sequences. And the output result is a real number between 0 and 1, so that the subsequent operation processing is facilitated, and the visual feeling of people on the result is facilitated.

Description

technical field [0001] The invention relates to the technical field of sequence sampling, in particular to a sample representative calculation method oriented to sequence sampling. Background technique [0002] The so-called sample representativeness of sequence-oriented sampling refers to an indicator of the extent to which a subsequence is representative of the entire sequence after a subsequence is extracted from the entire sequence. This representation can be used for some basic tasks in natural language processing (NLP) and its effect evaluation. Existing schemes generally only consider the ratio of the sampling number to the total number, but do not consider the span of the sampling subsequence and its distribution in the whole sequence. That is, the representativeness of the existing scheme = sampling ratio = number of sampling samples / total number. Even under the premise of the same sampling ratio, the span size and distribution uniformity of the sampling samples i...
