Geographic Query Parsing Data Set
Geographic Query Parsing
A geographic query is usually composed of three components, “what? “geo-relation?and “where? How to parse queries and extract these components from them is a key problem for geographic information retrieval (GIR).
The keywords in the “what?component indicate what users want to search; “where?indicates the geographic area users are interested in; “geo-relation?stands for the relationship between “what?and “where? For example, for a query “Restaurant in Beijing, China? “what?= “Restaurant? “where?= “Beijing, China? and “geo-relation?= “IN? For another query “Mountains in the south of United States? “what?= “Mountains? “where?= “United States? and “geo-relation?= “SOUTH-OF?
For the “what?component, we categorize it into three types, as listed below:
- Map type, users are looking for natural points of interests, like river, beach, mountain, monuments, etc.
- Yellow page type, users are looking for businesses or organizations, like hotels, restaurants, hospitals, etc.
- Information type, users are looking for text information, like news, articles, blogs, etc.
For the "geo-relation" component, a list of relation types is shown in Table 1.

Data Set
800,000 queries were collected from Windows Live Search logs (http://search.live.com/). Most of them were geographical queries. A sample labeled set of 100 queries were provided as a training set. This data set has been used in the geographic query parsing task of GeoCLEF 2007.
The query set is in XML format. Each query has two attributes:
The sample labeled set is in the following format. There are 4 more attributes:
