A comparison of methods for the automatic identification of locations in wikipedia

Davide Buscaldi, Paolo Rosso
2007 Proceedings of the 4th ACM workshop on Geographical information retrieval - GIR '07  
In this paper we compare two methods for the automatic identification of geographical articles in encyclopedic resources such as Wikipedia.  ...  The methods are a WordNet-based method that uses a set of keywords related to geographical places, and a multinomial Naïve Bayes classificator, trained over a randomly selected subset of the English Wikipedia  ...  Due to the lack of standardization that can be observed in the pages of Wikipedia, because of the 'open' nature of the Wiki project, the automatic identification of a Wikipedia page as one referring to  ...

Understanding user's query intent with wikipedia

Jian Hu, Gang Wang, Fred Lochovsky, Jian-tao Sun, Zheng Chen
2009 Proceedings of the 18th international conference on World wide web - WWW '09  
We demonstrate the effectiveness of this method in three different applications, i.e., travel, job, and person name. In each of the three cases, only a couple of seed intent queries are provided.  ...  We perform the quantitative evaluations in comparison with two baseline methods, and the experimental results show that our method significantly outperforms other approaches in each intent domain.  ...  According to the definition from Wikipedia, "Travel is the change in location of people on a trip, or the process of time involved in a person or object moving from one location to another" (  ...
