Presentation – Geocoding in Geographic Information Retrieval Systems

I presented this paper at the Geographic Information Systems II (GIS II) session at the 2014 Geography Symposium (See UT Geography Symposium Program 2014)

I represented The University of Tennessee School of Information Sciences at this interdisciplinary conference themed “Mapping outside the lines: Geography as a nexus for interdisciplinary and collaborative research.”

Tanner Jessel, School of Information Sciences, University of Tennessee. “Geocoding in Geographic Information Retrieval Systems.”

Information with a geographic component is among the most valuable and sought after types of information. However, the majority of geographical information exists as indirectly referenced locational information within unstructured text. Even among well-annotated, spatially explicit datasets, existing metadata can be of sparse, inconsistent, or otherwise of poor quality due to time and budgetary constraints. For these reasons, automated annotation of spatially explicit coordinates, a process known as geocoding, is an active area of research in geographic infor- mation science. Research concerning geocoding represents a long-term effort with a body of knowledge that has grown across several decades. Unfortunately, funding cycles are not always long-term, and some groundbreaking technologies and tools are no longer available. The present article attempts to synthesize the current state-of-the art of geocoding and presents a “toolkit” of resources used across the literature to accomplish geocoding, with an emphasis on applications for geographic information retrieval.
