 # Dataset Card for schema-summarization_spider
 ## Dataset Description
 ### Dataset Summary
+This dataset has been built to train and benchmark models uppon the schema-summarization task. This task aims to generate the smallest schema needed to answer a NL question with the help of the original database schema.
+This dataset has been build by crossing these two datasets :
+- `xlangai/spider`
+- `richardr1126/spider-schema`
+With the first dataset we take the natural language question and the SQL query. With the second dataset we take the associated schema of the databse id used to answer the question. We then generate the summarized-schema with the help of the SQL query
+
 ### Languages
+As the `xlangai/spider` and `richardr1126/spider-schema` are only labelled in english, this dataset is also labelled in english
