Index maintenance for time-travel text search
Avishek Anand, Srikanta Bedathur, Klaus Berberich, Ralf Schenkel · 2012
Time-travel text search enriches standard text search by temporal predicates, so that users of web archives can easily retrieve document versions that are considered relevant to a given keyword query and existed during a given time interval. Different index structures have been proposed to efficiently support time-travel text search. None of them, however, can easily be updated as the Web evolves and new document versions are added to the web archive.
