Programming With Unrestricted Natural Language

We argue it is better to program in a natural language such as English, instead of a programming language like Java. A natural language interface for programming should result in greater readability, as well as making possible a more intuitive way of writing code. In contrast to previous controlled language systems, we allow unrestricted syntax, using wide-coverage syntactic and semantic methods to extract information from the user’s instructions. We also look at how people actually give programming instructions in English, collecting and annotating a corpus of such statements. We identify differences between sentences in this corpus and in typical newspaper text, and the effect they have on how we process the natural language input. Finally, we demonstrate a prototype system, that is capable of translating some English instructions into executable code.
