Title: "Geographic Information Retrieval: Algorithms and Approaches"

    The goal of Geographic Information Retrieval (GIR) is to retrieve
relevant information resources in response to queries with geographic
constraints. GIR implies that the indexing and retrieval of objects in
a digital collection takes into account some form of georeferencing,
and may use various forms of geographical proximity, containment, or
other spatial relations in estimating or predicting geographic
relevance. Systems that provide searches using GIR methods, including
geographic digital libraries, and location-aware web search engines, are
based on a collection of georeferenced information resources and methods
to spatially search these resources with geographic location as part of
their search specifications.

Information resources in digital library collections can be considered
georeferenced if they are spatially indexed by one or more regions or
points on the surface of the Earth, where the specific locations of
these regions are encoded using spatial coordinates directly
(geometrically), or indirectly by toponyms (place names). In this
lecture we will examine the effectiveness of Geographic Information
Retrieval (GIR) methods in IR systems.

We will show how various types of information may benefit from explicit
geographic search, and where text-based place name search may be
sufficient. We will also show how implicit geographic search (or
geographic browsing) can be used to dynamically generate geographic
searches in geographic interfaces like Google Earth. We will
describe the algorithms used for Geographic search and how these may be
combined with topical text searches. In addition we will show results
from the GeoCLEF IR evaluation for text-based geographic search.

Short biography:

   Professor Ray R. Larson is a faculty member of the University of
California, Berkeley, in the School of Information. Prof. Larson
specializes in the design and performance evaluation of information
access systems, and the evaluation of user interaction with those
systems. His current research focuses on Geographic Information
Retrieval, Cross-Language Information Retrieval and Structured
(XML) retrieval using probabilistic methods. His background includes
work as a programmer/analyst with the University of California Division
of Library Automation (DLA) where he was involved in the design,
development, and performance evaluation of the UC public access online
union catalog (MELVYL). His past and current research has concentrated
on the design and evaluation of information retrieval systems, with an
emphasis on digital libraries. Prof. Larson was the principal
investigator for the “CHESHIRE Demonstration and Evaluation Project”
sponsored by the US Dept. of Education, that developed a next-generation
online catalog and full-text retrieval system. He was a co-principal
investigator for the “Searching Unfamiliar Metadata Vocabularies”
project sponsored by DARPA. Prof. Larson was also the principal
investigator of the “Cross-Domain Resource Discovery: Integrated
Discovery and Use of Textual, Numeric and Spatial Data” project
sponsored by NSF as part of the International Digital Libraries program.

Prof. Larson was Co-PI along with Michael Buckland and Fredric C. Gey
for the IMLS National Leadership grants “Seamless Searching of Numeric
and Textual Resources”,  “Going Places in the Catalog: Improved
Geographic Access”and most recently, “Support for the Learner: What,
Where, When and Who”. Prof. Larson is the PI on the recently awarded
IMLS National Leadership grant “Bringing Lives to Light: Biography in
Context.” Prof. Larson also teaches courses on the design and evaluation
of information systems,  including IS202 “Information Organization and
Retrieval”,IS257 “Database Management”,
IS240 “Principles of Information Retrieval”,  and IS245 “Organization of
Information in Collections”.
