### Dataset Summary

Spider is a large-scale complex and cross-domain semantic parsing and text-to-SQL dataset annotated by 11 Yale students
The goal of the Spider challenge is to develop natural language interfaces to cross-domain databases

### Supported Tasks and Leaderboards

The leaderboard can be seen at https://yale-lily.github.io/spider

### Languages

The text in the dataset is in English.

## Dataset Structure

### Data Instances

**What do the instances that comprise the dataset represent?**

Each instance is natural language question and the equivalent SQL query

**How many instances are there in total?**

**What data does each instance consist of?**

[More Information Needed]

### Data Fields

* **db_id**: Database name
