WP11 Multilingual semantic wiki - M9
Summary of progress
Three lines of work were followed: developing a multilingual ACE grammar (ACE-in-GF), extending the AceWiki system based on the GF technology (currently referred to as AceWiki-GF) and extending the Attempto reasoner RACE.
In collaboration with UGOT (John J. Camilleri) a GF-based multilingual grammar for ACE was developed. This grammar has the following properties:
- it covers the AceWiki subset of ACE, but is easily extendable towards full ACE
- it is available in 10 languages (in addition to ACE), but is easily extendable to other languages given that they are available in the GF resource grammar library
- its performance is similar to existing ACE parsers
- it is directly usable in AceWiki-GF
This resource is fully presented in Deliverable D11.1.
AceWiki-GF was further developed by adding preliminary support for multiple grammars, multiple articles, ambiguity management, and grammar editing. A large number of AceWiki-GF demo wikis have been made publicly readable/editable on the Attempto website. Most of these wikis are based on grammars developed in MOLTO and in previous GF-related projects. Some of the simpler grammars can also be edited. The current work on AceWiki-GF and its underlying ideas were published at CNL 2012 and presented as both a talk and a demo.
The Attempto reasoner RACE is currently extended to handle arithmetic, linear equations and text problems. This work – not being part of the actual MOLTO tasks – aims at providing AceWiki-GF with an alternative reasoning capability that covers the complete first-order subset of ACE. The current, still incomplete, version of RACE was demonstrated at CNL 2012.
Organization of meetings and conferences:
- 7-9 March the 4th MOLTO project meeting was organized by Norbert E. Fuchs at the University of Zurich
- 29-31 August the 3rd Workshop of Controlled Natural Language (CNL 2012) was organized by Tobias Kuhn and Norbert E. Fuchs at the University of Zurich

Deviations from Annex I
A small deviation is expected for the deliverables of this workpackage to allow time for Tobias Kuhn's contributions, who is a leading developer of AceWiki currently on a researcher's visit abroad. The revised schedule is as follows:
- D11.2 planned for M33 (end November 2012) is postponed to M34 (end December 2012)
- D11.3 planned for M37 (end March 2013) is postponed to M38 (end April 2013).
