A prototype context search engine (using default decay-as-N algorithm)

What is your context?

Location

Give OS co-ordinates of your location, these should be two values each of up to 7 digits; they should be FULL OS co-ordinates (i.e. the first digit should give the 100-kilometre shares -- this is often omitted when the reference is known to be within a certain 100km square). Leading zeroes are part of the reference and should NOT be omitted. The X and Y values should be separated by a comma, e.g. 292,092. Examples

What are your two OS co-ordinates:

Temperature

Give the temperature (in Fahrenheit) if you want to (you can also give a range , e.g. 60..70):

Time

Give the time, assuming a 24 hour clock, if you want to (give a pretended time if you want to visit the attraction at some future time):

THRESHOLD

Give the threshold matching score for retrieval, this should be a number between 2.0 (only perfect matches) and 0 (everything):

We are most grateful to the Leverhulme Foundation for support for creating the context matcher.

Examples of OS co-ordinates

The database covers the West Country; approximate co-ordinates of some of the main locations are:
