Data-to-Text

Suppose you ask a question that can be answered using data in a database, and you use a text-to-data model to map the question to a formal query in the database. The query evaluated on a database returns the answer in a structured representation, such as a table in a relational database or a graph in a graph database. The full cycle of natural language interfaces to databases is not complete without mapping this structured data to natural language, which is the topic of this chapter.
