|   An empirical exercise, based on the following example presented by Neil Christopher
|   at the NIST Semantic Distance Workshop, November 2003

|
|   In this version, we use a scalar Distance measure that Adrian proposed at the workshop.
|   ( A distance of 0 is unambiguous.  A distance >0 is a warning that ambiguity must be reduced )
|   However, it's important to note that what is in this file is simply a framework for exploring
|   different scalar and non-scalar measures, by running them to see what results we get.
|
|   Given some information about the following two systems:
|
|            ERP                                             GTM
|   Enterprise Resource Planning                      Global Trade Management
|    ( Alternatively                                   ( Alternatively
|    Sales Order Entry/Shipment                       Trade Management Operations
|    Enterprise Model View )                           Enterprise Model View )
|
|   Try some experiments aimed at answering the following questions:
|
|   Q1. Given two interface definitions, derived from their respective ontologies,
|       can the distance between the two be measured?
|
|   Q2.  Is this measure a single value? A set of like values with harmonized units ?
|
|   Q3. What factors would contribute to uncertainty in this measure?
|
|   Q4. Is time a factor in this measure? i.e. is it reasonable to expect distance measure to change over time?
|
|   Q5. Could a Distance Measure be mapped empirically to a $ cost of integration?
|
|   Q6. Could a Distance Measure be mapped empirically to a $ cost of maintenance?
