心理语言学刺激生成的反应式禁忌搜索算法
A Reactive Tabu Search Algorithm for Stimuli Generation in Psycholinguistics
摘要：
在心理语言学中，为了实验的目的，经常需要产生与某些统计和/或语言标准相匹配的无意义的“词”。这种刺激在认知神经科学文献中被称为假词或非词。构建非词的过程有时必须基于音节或词素等语言单位，当非词的大小增加时，会导致组合的数量爆炸。本文提出了一种反应式禁忌搜索算法来产生大小可变的非字。该方法通过使用一个改进的Metaheuristic算法的基础上增强了基于反馈的计划的局部搜索过程中建立伪词。实验结果表明，该算法是一种实用有效的非词生成工具。
英文摘要：
The generation of meaningless "words" matching certain statistical and/or linguistic criteria is frequently needed for experimental purposes in Psycholinguistics. Such stimuli receive the name of pseudowords or nonwords in the Cognitive Neuroscience literatue. The process for building nonwords sometimes has to be based on linguistic units such as syllables or morphemes, resulting in a numerical explosion of combinations when the size of the nonwords is increased. In this paper, a reactive tabu search scheme is proposed to generate nonwords of variables size. The approach builds pseudowords by using a modified Metaheuristic algorithm based on a local search procedure enhanced by a feedback-based scheme. Experimental results show that the new algorithm is a practical and effective tool for nonword generation.
