WADaR: Joint Wrapper and Data Repair
Summary: WADaR is a scalable tool for joint wrapper and data repair in web-scraped relations. It uses off-the-shelf entity recognizers to locate targets and Markov-chain repairs to fix data and wrappers; yields 15–60% quality gains and full wrapper repair in >50% without site knowledge.
