Preparing the 3rd KiWi Release: New Features and Stability Improvements
Over the last weeks we have spent much time on improving the KiWi system. Compared to the 0.2 prerelease, there is quite a number of changes upcoming:
- KiWi now supports very fast and very flexible facetted search, already tested with tens of thousands of articles; KiWi’s facetted search builds upon Apache SOLR, but also allows many “semantic” search features, as we add much of the RDF metadata to the index (thanks to Solr’s flexibility); the new search function is also the base for the geographic queries in the TagIT application, which are now incredibly fast!
- the TagIT application (actually developed as part of another project on top of KiWi) is moving into a state where it is good enough to be really used; we are currently running with around 15.000 news articles without any significant performance problems
- the Dashboard has been further improved with a history widget and a tagcloud widget; we are also currently working on the user profile functionality and hope to be able to include it in the next release
- the KiWi editor now features a first implementation of an RDFa plugin that allows to annotate parts of the text with RDF metadata
- many serious bugs have been fixed, so that the overall system stability is now better than ever and there are less unexpected issues
Besides these core changes that will also be available in the binary release, there has been quite some work in the extension part. Particularly, the work on information extraction is currenly progressing in an experimental extension called ieeval, the logica use case is developed in an extension called logica, and we are currently experimenting with routing functionality for the TagIT application. Christoph Lange has also begun to port his work on SWiM to the KiWi platform, so we might see the first KiWi application developed outside the project soon!
While the 0.3 prerelease is not (yet) available for download (we are still working on some issues), you can try out the latest changes with some live data – as always – on http://showcase.kiwi-project.eu/KiWi/.
