引言:对话推荐系统(CRS)旨在通过交互式的语言对话为用户提供推荐服务,它通常包括推荐和对话两个模块。传统的对话系统大多是一个端到端系统,将历史对话作为输入来产生应答,这往往利用语料库中的高频词产生回复,这种“安全”的回答往往缺乏有意义的信息。因此,基于知识增强的对话推荐系统被提出了,系统可以基于对话语境和外部知识,生成具有丰富信息并有意义的回答。

2.『不同知识来源的对话增强』

2.1 通过主题进行增强

在对话系统中,为了避免产生琐碎并且偏离主题的回复,基于主题增强的对话系统可以从潜在的主题中挖掘文档的高阶语义信息。

2.2 通过关键词进行增强

关键词:一个或多个单词的序列,为文档主要内容。

Sequence to Backward and Forward Sequences: A Content-Introducing Approach to Generative Short-Text Conversation

Generating responses with a specific emotion in dialog

Emotion-aware Chat Machine: Automatic Emotional Response Generation for Human-like Emotional Interaction

2.3 通过知识库进行增强

知识库存储,管理了大量大规模的信息,里面包含大量的三元组知识。

2.4 通过知识图谱进行增强

知识图谱是一种结构化的人类知识,由许多的知识三元组构成的。三元组由实体,关系和结构化介绍组成的。

2.5 通过文本进行增强

基于知识的文本指的是,提供与输入序列相关的额外文本信息。它对于理解输入序列与相关背景信息起着重要的作用,可以为对话系统提供额外的外部知识。
