Distributing the Edit History of Wikipedia Infoboxes
Thursday, May 30, 2013
Posted by Enrique Alfonseca, Google Research
Aside from its value as a general-purpose encyclopedia, Wikipedia is also one of the most widely used resources to acquire, either automatically or semi-automatically, knowledge bases of structured data. Much research has been devoted to automatically building
disambiguation resources
,
parallel corpora
and
structured knowledge
from Wikipedia. Still, most of those projects have been based on single snapshots of Wikipedia, extracting the attribute values that were valid at a particular point in time. So about a year ago we compiled and released a data set that allows researchers to see how data attributes can change over time.
Figure 1. Infobox for the Republic of Palau in 2006 and 2013 showing the capital change.
Many attributes vary over time. These include the presidents of countries, the spouses of people, the populations of cities and the number of employees of companies. Every Wikipedia page has an associated history from which the users can view and compare past versions. Having the historical values of Infobox entries available would provide a historical overview of change affecting each entry, to understand which attributes are more likely to change over time or have a regularity in their changes, and which ones attract more user interest and are actually updated in a timely fashion. We believe that such a resource will also be useful in
training systems to learn to extract data from documents
, as it will allow us to collect more training examples by matching old values of an attribute inside old pages.
For this reason, we released, in collaboration with
Wikimedia Deutschland e.V.
, a resource containing all the edit history of infoboxes in Wikipedia pages. While this was already available indirectly in Wikimedia’s full history dumps, the smaller size of the released dataset will make it easier to download and process this data. The released dataset contains 38,979,871 infobox attribute updates for 1,845,172 different entities, and it is
available for download
. A description of the dataset can be found in our paper
WHAD: Wikipedia Historical Attributes Data
, accepted for publication at the
Language Resources and Evaluation journal
.
What kind of information can be learned from this data? Some examples from preliminary analyses include the following:
Every country in the world has a population in its Wikipedia attribute, which is updated at least yearly for more than 90% of them. The average error rate with respect to the yearly World Bank estimates is between two and three percent, mostly due to rounding.
50% of deaths are updated into Wikipedia infoboxes within a couple of days... but for scientists it takes 31 days to reach 50% coverage!
For the last episode of TV shows, the airing date is updated for 50% of them within 9 days; for for the first episode of TV shows, it takes 106 days.
While infobox attribute updates will be much easier to process as they transition into the
Wikidata
project, we are not there yet and we believe that the availability of this dataset will facilitate the study of changing attribute values. We are looking forward to the results of those studies.
