Kaiko's going evasive

The recent failure of kaiko web server was due to a flow of SPARQL requests to DBnary. A client launched 46 Million requests (in less than a week) to the sparql server in a very brief delay, leading to an overflow of the log file that filled up the root partition and broke the server. May I remind everybody that the DBnary data is available easily by downloading turtle files that you may use either directly using adequate libraries (e.g. JENA in java or others in other programming languages) or upload in a local dbnary mirror.

Major bug discovered and fixed

While using DBnary in conjunction with other lemon resources (mainly during the Lider datathon in Madrid), we discovered a small but major problem with DBnary data. Until now, the lemon prefix was http://www.lemon-model.net/ while the official prefix was http://lemon-model.net/ leading to a poor mapping between DBnary data and other lemon datasets. The prefix has been fixed in the extractor and I also fixed ALL PREVIOUS VERSIONS of the dataset. Meaning that from now on, even if you use an older dataset (provided that you re-download it), you’ll have the correct mapping.

METEOR with DBNARY

The DBnary dataset has been used for an experiment on a Machine Translation Quality measure based on METEOR. The research paper will be presented during MT-Summit 2016. For work replication, we provide the sources of the experiment: full source code + data on dropbox

21 languages are now available

Latin is now part of the extracted languages. It is a rather small language, but, while we were participating to the first Summer Datathon (SD-LLOD2015) in Cercedilla (Spain), this language seemed quite expected by certain participants.

4 more languages immediately available

Thanks to Malick Diagne and Steve Roques, DBnary now extracts data from Dutch, Lithuanian, Serbo-Croat and Swedish editions. The Serbo-Croat language extractor also extracts morphological informations.

WikDict, a web service based on DBnary data

Karl Bartel has created a very simple web service to lookup translation of many languages. The data powering wikDict is provided by DBnary. The service is still preliminary, but I’m quite sure it will improve with the time. Go to wikDict home page…

Improvement in Russian extractor

Several bug fixes were made on the Russian extractor. Definitions should now be extracted in a more complete way and empty definitions should not be extracted anymore. Translation extraction has also been modified to avoid (rather unfrequent) special cases where links and usage notes where not extracted correctly.

French and German morphology is now extracted

Since December 2014, morphological data has been extracted from French and German language edition. This data is currently stored in exhaustive version, meaning that every inflected form may be found in an a lemon:otherForm property. German morphology extraction is still rather preliminar, but French version should already be in a form useful for DBnary users.

English extraction improved

English extraction has been improved slightly. More part of speeches are now extracted (mainly affixes, proverbs, …), Extracted data is now more precisely typed and described, using lexinfo vocabulary, Additionally, All lexical entries are now explicitly typed as LexicalEntry while they were previously typed as lemon:Word or lemon:Phrase or lemon:Adjective (all of which are sub classes of lemon:LexicalEntry).
