Update--Web Sources for Barcode Lookup:
Summary:
- Of the 50 Items scanned from my fiance's kitchen, a match was found for 29 items (58%).
- If beverages are removed from the list, the match rate for this set of scans jumps to 28/40 (70%).
- An interesting observation: in this set of scans, ALL store-brand products failed to match.
- Partial matching of UPCs yielded poor results
- For this set, 81% of the items which failed to match had a brand code which matched to something in the database. Perhaps brand could be used in some circumstances to make an educated guess about the properties of the item if a match cannot be made.
- positive example: Florida's Natural (low brand variance)
- negative example: Sam's Choice (high brand variance)
