This is the Arbogramo sentence treebank. What you can search, are data from the ELB project (Esperanta Lingvo-Banko), a growing set of Esperanto text corpora from the news, literature and web domains, automatically annotated with grammatical information and sentence structure by Eckhard Bick (VISL) as part of a joint venture with a group of programmers (Jacob Nordfalk, Rasmus H�yrup Jensen og Mads Sejersen) working for the youth section of the Danish Esperanto Association. Other aspects of the project include lexicography and web based language services, as well as applications for mobile phones. The EspGram-parser used in the project is a multi-stage hybrid system, containing both Constraint Grammar and Phrase Structure modules. EspGram is accessible for online use.
