Using Event Semantics for Toponym Disambiguation
2012This chapter discusses a method for improving the disambiguation of location names using limited event semantics. Location names are often ambiguous, as the same name may refer to locations in different states, countries, or continents. Ambiguous location names, also known as toponyms, need to be disambiguated (or grounded) when resolving many spatial ...

Toponym Disambiguation Using Ontology-Based Semantic Similarity
2012We propose a new heuristic for toponym sense disambiguation, to be used when mapping toponyms in text to ontology concepts, using techniques based on semantic similarity measures. We evaluated the proposed approach using a collection of Portuguese news articles from which the geographic entity names were extracted and then manually mapped to concepts ...

A conceptual density‐based approach for the disambiguation of toponyms
International Journal of Geographical Information Science, 2008Nowadays, a huge quantity of information is stored in digital format. A great portion of this information is constituted by textual and unstructured documents, where geographical references are usually given by means of place names. A common problem with textual information retrieval is represented by polysemous words, that is, words can have more than

Construction of a Japanese gazetteers for Japanese local toponym disambiguation
Proceedings of the 7th Workshop on Geographic Information Retrieval, 2013When processing toponym information in natural language text, it is crucial to have a good gazetteers. There are several well-organized gazetteers for English text, but they do not cover Japanese local toponyms. In this paper, we introduce a Japanese gazetteers based on Open Data (e.g., the Toponym database distributed by Japanese ministries, Wikipedia,

INTERNATIONAL JOURNAL ON Advances in Information Sciences and Service Sciences, 2012
This article considers the issue of the Geographic Information Retrieval (GIR) suggesting the development of techniques for disambiguation of toponyms based on ontologies to address the ambiguity in GIR queries. In particular, mixed domain ontology was built to way of organizing the Spanish-speaking countries, in order to develop a disambiguator method

A Classification Model with Corpus Enrichment for Toponym Disambiguation
2012This paper presents a method based on information retrieval to enrich corpus using bootstrapping techniques. A supervised corpus manually validated is provided, and then snippets are obtained from Web in order to increase the size of the initial corpus. Although this technique has already been reported in the literature, the main objective of this work
