内容简介

　　短文本表示建模，通常是指将短文本转化成机器可以诠释的形式，旨在帮助机器“理解”短文本的含义。本书详细介绍了短文本表示建模研究体系中具有代表性的短文本概念化表示建模研究分支和短文本向量化表示建模研究分支的相关研究方法，既涵盖了大量经典算法，又特别引入了近年来在该领域研究中涌现出的新方法、新思路，力求兼顾内容的基础性和前沿性。同时，本书融入了作者多年来从事以概念化和向量化为核心的短文本表示建模方法与理论研究的经验和成果，并以短文本检索这一典型应用问题为例，详细介绍了如何把短文本概念化表示建模方法和短文本向量化表示建模方法以及先进的设计思想融入具体应用问题的求解。本书可供计算机、信息处理、自动化、系统工程、应用数学等专业的教师以及相关领域的研究人员和技术开发人员参考。
