Abstract

Regular expressions are used in many information extraction systems like YAGO, DBpedia, Gate and SystemT. However, they sometimes do not match what their creator wanted to find. We investigate how missing words can be added automatically to a regular expression by creating disjunctions at the appropriate positions. Our demo visualizes the steps that our algorithm employs to repair the regular expression.
