Rule mining in knowledge bases

Abstract : The continuous progress of information extraction (IE) techniques has led to the construction of large general-purpose knowledge bases (KBs). These KBs contain millions of computer-readable facts about real-world entities such as people, organizations and places. KBs are important nowadays because they allow computers to “understand” the real world. They are used in multiple applications in Information Retrieval, Query Answering and Automatic Reasoning, among other fields. Furthermore, the plethora of information available in today’s KBs allows for the discovery of frequent patterns in the data, a task known as rule mining. Such patterns or rules convey useful insights about the data. These rules can be used in several applications ranging from data analytics and prediction to data maintenance tasks. The contribution of this thesis is twofold : First, it proposes a method to mine rules on KBs. The method relies on a mining model tailored for potentially incomplete webextracted KBs. Second, the thesis shows the applicability of rule mining in several data-oriented tasks in KBs, namely facts prediction, schema alignment, canonicalization of (open) KBs and prediction of completeness.
