Finding similar cases
Finding the similar cases is not rocket science
Remember, aim is to find a few similar cases
- can be used by field staff as basis for new quote
- want a manageable number (e.g. 20)
Main technique is to relax values of features
- e.g. “item Athol_B23” becomes “T31_fan_coil”
- where Athol_B23 is one specific type of T31_fan_coil
- allows retrieval of installations using other types
- e.g. “temperature = 65 F” becomes “60F < T < 65F”
Knowledge engineering used to find relaxations
- e.g. use of domain experts to advise on suitable relaxations
