ECOLE: A Look-ahead Editor for a Controlled Language
Rolf Schwitter, Anna Ljungberg, Hood David · 2003
This paper presents ECOLE, a look-ahead text editor that supports authors writing seemingly informal specifications in PENG, a computer-processable controlled natural language. ECOLE communicates via a socket interface with the controlled language processor of the PENG system. After each word form entered the look-ahead editor displays appropriate look-ahead categories. These syntactic hints tell the author what kind of word or syn-tactic structure can follow the current in-put string and reduce thereby the cogni-tive burden to learn and remember the controlled language. While the author types the text word by word and adds un-known content words on the fly to the lex-icon, a discourse representation structure and a paraphrase is built up dynamically for the text in a completely compositional manner. The arising specification can be checked automatically for consistency and informativity with the help of third-party reasoning services. 1
