On assigning place names to geography related web pages

place name disambiguation
place name assignment
Issue Date: 
Paper presented at the Joint Conference on Digital Libraries, Denver, CO, 2005.
In this paper, we attempt to give spatial semantics to web
pages by assigning them place names. The entire assignment
task is divided into three sub-problems, namely place name
extraction, place name disambiguation and place name as-
signment. We propose our approaches to address these sub-
problems. In particular, we have modified GATE, a well-
known named entity extraction software, to perform place
name extraction using a US Census gazetteer. A rule-based
place name disambiguation method and a place name as-
signment method capable of assigning place names to web
page segments have also been proposed. We have evalu-
ated our proposed disambiguation and assignment methods
on a web page collection referenced by the DLESE meta-
data collection. The results returned by our methods are
compared with manually disambiguated place names and
place name assignment. It is shown that our proposed place
name disambiguation method works well for geo/geo ambi-
guities. The preliminary results of our place name assign-
ment method indicate promising results given the existence
of geo/non-geo ambiguities among place names.
