The increasing dependence of daily human life on internet has greatly increased the importance of capturing geographical information on the web, due to the ground fact that most human activities occur locally. Hence, geographical information retrieval has gained lot of importance these days. Also today blogs have become a means for people to express their thoughts, actions, and their reactions. Various techniques have been proposed for geotagging documents based on their content by identifying placenames, disambiguating them and then finding the geographical focus of the document. In this thesis we propose a technique for geotagging blogs without disambiguating the placenames individually. Geotagging the blogs would improve the precision and recall of the Geo-IR systems since it would help to extract more relevant documents with the added information about the target geography of the blog.
