Approximate String Matching for Geographic Names and Personal Names
The problem of matching strings allowing errors has recently gained importance, considering the increasing volume of online textual data. In geotechnologies, approximate string matching algorithms find many applications, such as gazetteers, address matching, and geographic information retrieval. This paper presents a novel method for approximate string matching, developed for the recognition of...
متن کاملInferring Location Names for Geographic Information Retrieval
For the participation of GIRSA at the GeoCLEF 2007 task, two innovative features were introduced to the geographic information retrieval (GIR) system: identification and normalization of location indicators, i.e. text segments from which a geographic scope can be inferred, and the application of techniques from question answering. In an extension of a previously performed experiment, the latter...
متن کاملDisambiguating Geographic Names in a Historical Digital Library
Geographic interfaces provide natural, scalable visualizations for many digital library collections, but the wide range of data in digital libraries presents some particular problems for identifying and disambiguating place names. We describe the toponym-disambiguation system in the Perseus digital library and evaluate its performance. Name categorization varies significantly among different ty...
متن کاملBBK-UFRGS@CLEF2009: Query Expansion of Geographic Place Names
For our first participation on CLEF, our aim was to compare plain information retrieval strategies and query expansion and emphasis of geographic terms. ANNIE was used to recognise geographic entities which were expanded using Google's Hierarchical List of Geographical Place Names. The idea was that the expansion would produce more accurate answers. The results have shown the opposite. Our best...
متن کاملAssigning textual names to sets of geographic coordinates
NameSet is a system that translates a set of geographic coordinates into a textual name based on the geographic regions where the coordinates occur. One possible application of NameSet is to concisely present the geographical scope of a set of geo-referenced observations to a human user. Another application is to generate text to depict a set of coordinates that appear on a web site – text that...
