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: <QUERYNO> and <QUERY>.

<QUERY>Restaurant in Beijing, China</QUERY>

<QUERY>Real estate in Florida</QUERY>

<QUERY>Mountains in the south of United States</QUERY>

The sample labeled set is in the following format. There are 4 more attributes: <LOCAL>, <WHAT>, <WHAT_TYPE>, <GEO-RELATION> and <WHERE>.

<QUERY>Restaurant in Beijing, China</QUERY>

<WHAT>Restaurant</WHAT>

<WHAT-TYPE> Yellow page</WHAT-TYPE>

<GEO-RELATION>IN</ GEO-RELATION>

<WHERE>Beijing, China</WHERE>

<LAT-LONG>40.24, 116.42</LAT-LONG>

<QUERY> Lottery in Florida</QUERY>

<WHAT>Lottery</WHAT>

<WHAT-TYPE>Information</WHAT-TYPE>

<GEO-RELATION>IN</ GEO-RELATION>

<WHERE>Florida</WHERE>

<LAT-LONG>28.38, -81.75</LAT-LONG>
