Toponym Disambiguation in Information RetrievalBuscaldi, Davide 12 November 2010 (has links)
In recent years, geography has acquired a great importance in the context of
Information Retrieval (IR) and, in general, of the automated processing of
information in text. Mobile devices that are able to surf the web and at the
same time inform about their position are now a common reality, together
with applications that can exploit this data to provide users with locally
customised information, such as directions or advertisements. Therefore,
it is important to deal properly with the geographic information that is
included in electronic texts. The majority of such kind of information is
contained as place names, or toponyms.
Toponym ambiguity represents an important issue in Geographical Information
Retrieval (GIR), due to the fact that queries are geographically constrained.
There has been a struggle to nd speci c geographical IR methods
that actually outperform traditional IR techniques. Toponym ambiguity
may constitute a relevant factor in the inability of current GIR systems to
take advantage from geographical knowledge. Recently, some Ph.D. theses
have dealt with Toponym Disambiguation (TD) from di erent perspectives,
from the development of resources for the evaluation of Toponym Disambiguation
(Leidner (2007)) to the use of TD to improve geographical scope
resolution (Andogah (2010)). The Ph.D. thesis presented here introduces
a TD method based on WordNet and carries out a detailed study of the
relationship of Toponym Disambiguation to some IR applications, such as
GIR, Question Answering (QA) and Web retrieval.
The work presented in this thesis starts with an introduction to the applications
in which TD may result useful, together with an analysis of the
ambiguity of toponyms in news collections. It could not be possible to
study the ambiguity of toponyms without studying the resources that are
used as placename repositories; these resources are the equivalent to language
dictionaries, which provide the di erent meanings of a given word. / Buscaldi, D. (2010). Toponym Disambiguation in Information Retrieval [Tesis doctoral no publicada]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/8912 / Palancia
