Besides finding it amusing I also related to it since I have used an example with light bulbs in a webinar about data matching as seen here:
The use of synonyms in Search Engine Optimization (SEO) is very similar to the techniques we use in data matching.
Here the problem is that for example these two product descriptions may have a fairly high edit distance (very different character by character), but are the same:
- Light bulb, A 19, 130 Volt long life, 60 W
- Incandescent lamp, 60 Watt, A19, 130V
while these two product descriptions have an edit distance of only one substitution of a character, but are not the same product (though being same category):
- Light bulb, 60 Watt, A 19, 130 Volt long life
- Light bulb, 40 Watt, A 19, 130 Volt long life
Working with product data matching is indeed very enlightening.
