Semantic Expansion of Text Retrieval Term Based on Neural Network

Abstract

Abstract: Following a brief introduction to the features of textual data and text retrieve, this paper presents a basic method of semantic expansion of

摘要： 在讨论文本数据和文本检索特点的基础上,提出了一种运用神经网络进行检索词语义扩充的基本方法,对其中的检索词矢量化问题提出了一种方法,重点阐述在语义扩充中选择LVQ神经网络的原因、LVQ网络的修正学习算法和有关补充说明,最后给出实证证明神经网络方法进行检索词语义扩充的可行性。
