Notes

• It proposes a Framework for IE-based Ontology Population (Ontology-based Information Extraction).
• It uses the term Identity Resolution for Entity Mention Normalization.
• It defines Identity Relation as:
  • “the process of deciding whether an instance extracted from text refers to a known entity in the target domain (e.g. the ontology)”
  • “the process of deciding if a particular fact extracted from text It can be linked to identical/similar facts in the ontology.”.
• It implements the Framework and tests it on Employment Posting Information Extraction.
• implementation makes use of:
  • The extensible PROTON Ontology. (Terziev et al., 2005)
  • The Knowledge Base System used is KIM System (Popov et al., 2004)

that is based on OWLIM (Kiryakov et al., 2005) and Sesame.

Abstract

In the context of ontology-based information extraction, identity resolution is the process of deciding whether an instance extracted from text refers to a known entity in the target domain (e.g. the ontology). We present an ontology-based framework for identity resolution which can be customised to different application domains and extraction tasks. Rules for identify resolution, which compute similarities between target and source entities based on class information and instance properties and values, can be defined for each class in the ontology. We present a case study of the application of the framework to the problem of multi-source job vacancy extraction.
