Distributed agents for online spatial searches
Distributed agents for online spatial searches

    As the availability and utilisation of online data blossoms, automated online searches―whether to answer a simple question, seek speci?c sensor readings, or investigate research in a particular domain―have raised a number of issues. Simple search tools do not access the deep web of services and online forms, and cannot handle knowledge domain-speci?c search problems, but specialist search tools can have a narrow domain and applicability. Some online tools circumvent these problems by putting more ?lter con- trols into the hands of users, but this leads to more complex interfaces which can raise usability barriers. A distributed approach, where specialised search agents act autonomously to ?nd contextualised information, can provide a useful compromise between a simple, general search interface and specialist searches. This paper outlines work in progress on design and use of specialist search agents, with a case study to ?nd public transportation bus stopswithin a spatial region. The approach is demonstrated with a proof of concept web interface, developed to interpret a text query to ?nd and show bus stop locations within a named boundary by coordinating multiple online search agents. Search agents were designed to follow a common model to allow for future development of agent types, including specialist agents used in the case study to search standard open web services and extract spa- tial features.
