Hi Steven, And welcome to the list :)
You've spotted a bug, or kind of a bug. Our infobox extraction algorithm supports the extraction of dates (see e.g. the "date" property in http://dbpedia.org/page/Battle_of_New_Orleans), but doesn't (or at least doesn't seem to) support time spans (e.g. in Battle_of_Baltimore). my question @all: How to best represent timespans in RDF? Can't offer you an immediate solution, sorry, but when someone fixes this bug, the next dataset should have your data :) Please feel free to submit a bugfix yourself. Our code is open source, available at http://dbpedia.svn.sourceforge.net/viewvc/dbpedia/ Cheers, Georgi -- Georgi Kobilarov Freie Universität Berlin www.georgikobilarov.com > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:dbpedia- > [EMAIL PROTECTED] On Behalf Of Steven Isley > Sent: Monday, April 21, 2008 3:48 AM > To: [email protected] > Subject: [Dbpedia-discussion] Extracting Date Information > > Hello Everyone, > > First off, I want to apologize in advance for any obvious questions I > may ask.
