WP11 Multilingual semantic wiki - M3

Multilingual Online Translation

Summary of progress

During the first 3 months of our participation in the MOLTO project we completed an initial integration of the GF-provided services (mainly translation and look-ahead editing) into AceWiki.

We implemented a new Java front-end to the GF Webservice, and use it to connect to the GF services from AceWiki. The existing AceWiki user interface was extended to allow for an easy switching between different languages and to present with each sentence its GF-provided analysis (translations into other languages, word alignment diagrams, GF syntax trees, etc.). The AceWiki storage format was changed to a one based on GF abstract trees (which are language-neutral).

The other main part of our work dealt with the implementation of the ACE grammar in GF. We tested an existing implementation (Angelov and Ranta, 2009) which targets an earlier version of ACE for its recall and precision, and found that some changes need to be introduced to make it compatible with the latest version of ACE. More importantly, we decided to focus on and also started work on a grammar of the subset of ACE that is used in the current AceWiki.

We also experimented with taking the content of an existing AceWiki demo wiki (domain Geography) and using it to pre-populate the new GF-based AceWiki.

Highlights

  • integration of the existing AceWiki with the existing GF webservice, allowing for multilingual viewing and editing of the wiki content
  • analysis of the existing GF implementation of the ACE grammar
