GIR Experimentation
Geographic Information Retrieval (GIR) community has generally accepted the thesis that both thematic and geographic aspect of documents are useful for GIR. This paper describes a preliminary experiment exploring this thesis by seperately index-ing/searching geographical relevant-terms (place names, geo-spatial relations, geographic concepts and geographic adjacetives) extracted from reference ...

Ground source heat pumps are receiving increasing interest in North America and in some countries in Europe. The technology is well established with over 400 000 units (80% of which are domestic) installed worldwide and about 45 000 installed annually although most systems in the United States are of the reversible type. Very few systems have been installed in the UK. Efficiencies for ground so...
متن کاملForostar: A System for GIR
We detail our methods for generating and applying co-occurrence models for the purpose of placename disambiguation. We explain in detail our use of co-occurrence models for placename disambiguation using a model generated from Wikipedia. The presented system is split into two stages: a batch text & geographic indexer and a real time query engine. Four alternative query constructions and six met...
متن کاملMMIS at GeoCLEF 2008: Experiments in GIR
In this paper we present our Geographic Information Retrieval System, Forostar, and the results of three experiments. We compare two data fusion methods, and show that a simple geographic filter outperforms a penalty based system. We compare context based disambiguation to a default gazetteer and show no significant difference. Finally we compare a unique geographic index to an ambiguous geogra...
متن کاملLAF/GrAF-grounded Representation of Dependency Structures
This paper shows that a LAF/GrAF-based annotation schema can be used for the adequate representation of syntactic dependency structures in many languages. We first argue that there are at least two types of textual units that can be annotated with dependency information: words/tokens and chunks/phrases. Based on this consideration, we discuss a sub-typing of GrAF to represent the corresponding ...
