Automating Search Interfaces

    Geographic/Spatial queries are a well-researched topic in the database literature. Free text retrieval is definitely a weak approach, though people attempt it by using thesaurus facilities to represent the structure of a gazetteer. In most of the practical systems I have seen, spatial query is done using postal codes: the system needs knowledge of which postal districts are near each other. (We also use such techniques for scheduling the itinerary of service engineers).

    Multilingual search is well researched and seems to work reasonably well. The more difficult problem is to distinguish agencies that can book you a hotel room from newsletter articles by people enthusing what a wonderful hotel room they were staying in: I think this is why there will always be added value in manual categorization and indexing services.
