Resumen:
Toward the quickly growing of information available on the web, to recover, in a
simple and efficient way, documents that meet the increasingly specific needs of the users is
the major challenge in Information Retrieval (IR). Besides the large amount of information,
another issue that interferes on process of acquisition by the user is the fact, that information
need be expressed with a few keywords. In this scenario, query expansion techniques are
applied in order to add new terms to the original query in order to enrich it semantically. Most
of these expansion techniques have been applied to geographic locations terms, because the
geographical context plays an important role in identifying the real user needs. However,
these techniques are restricted to terms that represent a geographic location and fail to
consider that the vocabulary used by is different according to geographical region. So, i f the
user uses a term of his knowledge, in other words, from its region, to do a search for
documents from other region, and this term isn't widely used in this region, the result of your
query will be compromised. Therefore, this paper presents an information retrieval system,
which uses the geographical context of the terms to semantically expand users' queries.
