“…There have been recently several complicated mechanisms converting from natural language to semantic one (Cimiano, Haase, & Heizmann, 2007;Lopez, Pasin, & Motta, 2005). For example, QUICK search engine (Zenz, Enrico, Wolf, & Wolfgang, 2012) generates a complete semantic query space, that is, a set of all possible semantic queries for a given set of keywords. It first identifies all possible query patterns called query template, then generates semantic queries by binding keywords to query templates.…”
