Artificial Linguistic Internet Computer Entity

2. ALICE is super ELIZA!

3. The Loebner Prize
In 1990 Hugh Loebner agreed with The Cambridge Center for Behavioral Studies
2001 Richard Wallace – Alice bot

4. Alice and the Bots Richard Wallace ALICE – a conversational agent
Multiple clients and wrappers
Supported by A.L.I.C.E. Artificial Intelligence Foundation (
Many versions: ProgramD, ProgramN, etc.

Should not be judged by its cover.

</category>

8. GraphMaster AIML X Input -> Response
Needed – an efficient algorithm
Matching Order must be defined
Depth first search
Patterns may be ordered by some bots
GraphMaster works word by word

9. GraphMaster Structure
AIML patterns are transformed into a tree
Nodes of tree are words to match
Input transformed into a path
Recursive (<srai> tags)

10. Matching Order Constrains on order: Order: Wildcards: _ and *
Last Bot output: THAT
Bot Topic: TOPIC
Order:
Match _ first
Match word
Match *

11. Path
Input string becomes:
input <that> THAT <topic> TOPIC

12. Brain Image
Alice – ~ 24,000 Categories

16. Why does ALICE work? Combinatorics Alice testing
Assuming 10 word choices per word
20 word sentences -> 1020 sentences
Alice testing
1800 starting word for 95% coverage
Second word choice is ~2

Collects a user profile

18. Where Next?
Does Alice think?
How well does Alice work as a front-end?
