GIR

Semantic aligning of heterogeneous geographical data from different sources behaves unsatisfactory on Geographical Semantic Web (GSW) due to the flat structure of GSW and the influence of spatial features. To solve this problem, this paper proposes a ...

Advances in technology have continually progressed our understanding of where people are, how they use the environment around them, and why they are at their current location. Having a better knowledge of when various locations become popular through ...

The work in this paper is motivated from two different perspectives: First, gazetteers as an important data source for Geographic Information Retrieval (GIR) applications often lack historic place name information. More focused historic gazetteers are a ...

Farmers face pressure to respond to unpredictable weather, the spread of pests, and other variable events on their farms. This paper proposes a framework for data aggregation from diverse sources that extracts named places impacted by events relevant to ...

Events as composites of temporal, spatial and actor information are a central object of interest in many information retrieval (IR) scenarios. There are several challenges to such event-centric IR, which range from the detection and extraction of ...

We propose a categorization algorithm for text content description such as tags for images from social media or crowd sourcing services, to identify places characteristics. The algorithm is based on a spatial coverage and a multi-facets categorization. ...

Ongoing initiatives promoted by cultural institutions and public administrations engage in the development of textual corpora issued from the general public. In this work, we deal with a spoken corpus of life stories and a crowd-sourced Web corpus of ...

In this paper, we point out to the shortcomings of precision and recall in evaluating the performance of geoparsing algorithms. We propose separate processes for evaluating toponym recognition and toponym resolution stages, and also propose new metrics ...

Local news articles are an important source of knowledge about local events, place-specific culture, and peoples' thoughts about their environment. Reliable geocoding of such articles is the first step towards unlocking such local knowledge for ...
