阿里雲智能語義理解Quick Start

作者：俏巴

概述

智能語義理解（Intelligent Semantic Understanding）依託阿里巴巴在深度學習、自然語言處理方向上的技術積累，為客戶提供文本相似度和機器閱讀理解等優質算法技術。其中文本相似度可以計算兩段短文本之間的相似度，並給出相似度評分；機器閱讀理解能針對某幾個問題，從若干篇文章中分別尋找問題答案。智能語義理解技術可以應用於問答系統、信息檢索、新聞推薦等場景。下面主要介紹該產品的開通及使用。

Step By Step

1、開通服務，公測申請地址。

2、開通後控制檯概覽

3、操作步驟，可以在控制檯快速查看創建項目，然後查看進程

4、使用SDK進行相關操作

5、Demo相關解釋

• 5.1 UploadDictionary作用：

幫助分詞，業務的一些專有詞，默認分詞分不出來的情況下需要用上傳到自定義詞表。

• 5.2 上傳數據格式參考及解釋：數據格式說明。
• 5.3 用戶答疑釘釘群號：23162166。（可在文件位置獲取產品簡介文檔，對理解產品有很大幫助）
