Abstract-Biodiversity studies all life forms that we find in nature. The maintenance of biological diversity is important because it is essential to life on Earth. The lack of accurate spatial geographic information in species occurrence data, especially from diversity rich regions (like the Amazon Forest), leads to problems in many conservation activities, such as systematic planning for the protection of endangered species. In this paper, we present a gazetteer (a geographical directory that associate name places to geographic coordinates) for biodiversity data that is available as an Linked Open Data resource (using a GeoSPARQL Endpoint) and show how it can be used to improve inaccurate geographic collection data. We compared the efficiency of our Gazetteer with three openly available resources, Geonames, WikiMapia and Wikipedia, and got a 10% better recall rate than these endpoints. We also used the Gazetteer to correct geographic data from a big record sample (327,000 occurrence records) from SpeciesLink and GBIF (two big open access repositories of biodiversity occurrence data). In this data set, we were able to add geographic coordinates to around 14% of records that did not have them before.

Abstract. We propose techniques for achieving the geographical navigation of historical events described in Web pages as "Virtual History Tour". First, we develop a method for extracting information on the historical events from the Web and organizing it into a chronological table. Our method can effectively handle ambiguous cases -homonyms and multiple location names in a sentence -by using the number of cooccurrences among events, person names, location names, and addresses in the Web. Next, we propose a method for ranking historical entities according to their impacts at specific time and location. We extend the PageRank algorithm to calculate the temporal and spatial impacts of entities. Finally, we introduce our concrete application demonstrating how users can browse historical events through timeline and map interfaces.

Vernacular place names are names that are commonly in use to refer to geographical places. For purposes of effective information retrieval, the spatial extent associated with these names should reflect peoples perception of the place, even though this may differ sometimes from the administrative definition of the same place name. Due to their informal nature, vernacular place names are hard to capture, but methods to acquire and define vernacular place names are of great benefit to search engines and all kinds of information services that deal with geographic data. This paper discusses the acquisition of vernacular use of place names from web sources and their representation as surface models derived by kernel density estimators. We show that various web sources containing user created geographic information and business data can be used to represent neighbourhoods in Cardiff, UK. The resulting representations can differ in their spatial extent from administrative definitions. The chapter closes with an outlook on future research questions.
