your natural language queries into SQL statements that can be executed against an SQL Server database. This will allow you to interact with your data in a more intuitive and user-friendly way. No more struggling with complex SQL syntax – just speak your query and let the system do the ...
To overcome this, we are doing our project on SQL Query formation using Natural Language Processing (NLP). This project aims at developing a system which will accept English query from user and convert it into SQL. This helps novice user who can easily get required contents without knowing ...
应用 Bert 的地方明显在搜索重排序阶段,应用模式与 QA 也是类似的,就是把 Query 和 Document 输入 Bert,利用 Bert 的深层语言处理能力,作出两者是否相关的判断。如果是 Passage 级别的短文档检索,其实流程基本和 QA 是一样的;而如果是长文档检索,则需要增加一个如何处理长文档的技术方案,然后再走 Bert 去做相关...
Natural Language to SQL( NL2SQL)即旨在将人类的自然语言自动转化为相应的SQL语句(Structured Query Language结构化查询语言),使算法能与数据库直接交互、并返回交互的结果,并服务于子查询预测、SQLNet的替代方案的研究。NL2SQL作为新兴研究领域,以自然语义理解(NL)为技术底层,将机器学习(ML)和深度学习(DL)应用于...
另外,还有两篇做NLP to SQL的工作(Achieving 90% accuracy in WikiSQL/ Table2answer: Read the database and answer without SQL),意思是不用你写SQL语句,而是用自然语言发出命令,系统自动转化成可执行的SQL语句,使用Bert后,也取得了一定幅度的性能提升。我理解这种任务因为是领域受限的,所以相对容易些,我个人对...

While working on normal database system, to retrieve data from database we have to know about the SQL Query language to retrieve exact data from the database. But everyone doesnt have exact knowledge about the SQL Query language. For retrieving data from the database they have to enter the...
