| File Name | Description | Size/Download |
|---|---|---|
| emoticons-sorted-by-length.txt | All unique emoticon triplets used in the system, sorted by length (number of characters). | 30 kB /  |
| emoticon-unique-chars-with-frequencies.txt | All unique characters appearing in all emoticons used in the system, with their frequencies within database. | 5 kB / |
| emodetector.zip | A simple Perl script that decects the presence of emoticons (or emoticon bundle). Should work for most cases. It uses a simplified version of algorithm used in CAO to detect the presence of emoticons. | 4 kB / |

Development History
- soon - rewrite the system into Perl, fix long startup time, fix partial emoticons, add online demo.
- 2010 Jan [CAO 1.0]
- Original experimental version written in C#.
- Has five different ways of score calculation,
- long initial stratup time (loads all emoticon combinations into memory),
- partial emoticons (without one eye, or mouth) not always work.
