內(nèi)容簡介

　　短文本表示建模，通常是指將短文本轉(zhuǎn)化成機(jī)器可以詮釋的形式，旨在幫助機(jī)器“理解”短文本的含義。本書詳細(xì)介紹了短文本表示建模研究體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關(guān)研究方法，既涵蓋了大量經(jīng)典算法，又特別引入了近年來在該領(lǐng)域研究中涌現(xiàn)出的新方法、新思路，力求兼顧內(nèi)容的基礎(chǔ)性和前沿性。同時(shí)，本書融入了作者多年來從事以概念化和向量化為核心的短文本表示建模方法與理論研究的經(jīng)驗(yàn)和成果，并以短文本檢索這一典型應(yīng)用問題為例，詳細(xì)介紹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進(jìn)的設(shè)計(jì)思想融入具體應(yīng)用問題的求解。本書可供計(jì)算機(jī)、信息處理、自動(dòng)化、系統(tǒng)工程、應(yīng)用數(shù)學(xué)等專業(yè)的教師以及相關(guān)領(lǐng)域的研究人員和技術(shù)開發(fā)人員參考。
