Noise Word Lists

In its Analytics Guide, Relativity recommends a noise word list posted to a Dutch site Ranks. Ranks has noise word lists available in several different languages, including Japanese, Chinese, French and German.

There are actually several noise word lists for English.

1. A long list of 668 words. It includes less obvious words such as accordance; beginning; looking; predominantly; and usefulness, as well as each single letter in the alphabet.

2. A short list of 174 words.

3. The MySQL stop word list of 543 words that does not include single letter words.

Surprisingly the MySQL and Ranks long list noise word lists are quite different. There are 206 words in the long Ranks list which are not in the MySQL list, and 82 words in the MySQL list omitted from the Ranks long list. As you can see from the lists below, the MySQL list tends to include more contractions, and the Ranks Long List has more common adverbsand misspellings or grammatical mistakes.
