NLP Cloud is an API for natural language processing.
什么是嵌入？
嵌入是文本片段的向量表示。如果两个文本具有相似的向量表示，则很可能意味着它们具有相似的含义。
设想有以下 3 个句子：
NLP Cloud proposes an API dedicated to NLP at scale.
I went to the cinema yesterday. It was great!
以下是上述 3 个句子的嵌入结果（为简洁起见已截断）：

嵌入是自然语言处理的一个核心特征，因为一旦机器能够检测到文本之间的相似性，就能为语义相似性、RAG（检索增强生成）系统、语义搜索、转述检测、聚类等许多有趣的应用铺平道路。
