A Classification Model with Corpus Enrichment for Toponym Disambiguation
Lecture Notes in Computer Science, 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

Toponym Disambiguation Using Ontology-Based Semantic Similarity
Lecture Notes in Computer Science, 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 ...

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 ...

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,

Map-based vs. knowledge-based toponym disambiguation
Proceedings of the 5th Workshop on Geographic Information Retrieval, 2008Toponym Disambiguation, i.e. the task of assigning to place name their correct reference in the world, is getting more attention from many researchers. Many methods have been proposed since now, making use of different resources, techniques and sense inventories.

Toponym disambiguation in online social network profiles
Proceedings of the 23rd SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2015In online social networks individuals are given the option to reveal on their online profiles some personal information about themselves including, among others, their home location that, if specified, is typically referred to with a toponym. A toponym disclosed by an individual on her profile, or self-reported toponym (e.g., "London"), is often ...

Toponym disambiguation in historical documents using network analysis of qualitative relationships
Proceedings of the 3rd ACM SIGSPATIAL International Workshop on Geospatial Humanities, 2019In this paper we use network analysis to identify qualitative "neighbors" for toponyms in an eighteenth-century French encyclopedia, but could apply to any entry-based text with annotated toponyms. This method draws on relations in a corpus of articles, which improves disambiguation at a later stage with an external resource.

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
