Potential chatbot for the masses or an Expert System?
« on: November 19, 2010, 10:46:33 pm »
After watching a few videos of this bot, I was pretty impressed with it's abilities, to say the least.

The bot seems to make inferences on usages like "it" when the it describes a person in a previous sentence or question.

The topic seems to flow quite smoothly and the bot talks to the person not just providing bland answers.

It reminds me a lot of Leslie Spring's bot, Silvia, in its abilities.

I have written a couple emails to their company rep but have not received any answers yet.

No, the bot isn't released to the general public and they only have the videos to show so that's why I emailed them to inquire about whether the bot was scripted, can it learn from conversations, etc....

We'll see but by all means, check out Cassandra at: http://www.ejtalk.com/v1/bio.html

Click on DEMO.

I'd like to hear some thoughts on this bot.
In the world of AI, it's the thought that counts!

This has grabbed my attention Art, my type of bot, it seems smart and appears to stay on topic very well indeed.

I noticed the person talking to it didn’t once say, how are you? Or what is your favourite xxxxx, at last a bot is made that might actually have a real life use.

I bet if you ask it “what are you?” it will give a truthful answer, just a hunch but I think the makers of this bot have tried to keep it real.    

It looks like a Haptek character too, I wonder if it is.

I thought this vid was great, it even talked about one of my favourite topics and the detail it has and the answers it gives, very impressive.  


correction the guy talking did say how are you, my bad.  :o

  From the video I feel like I just visited someone who worked at a sky watch station.  Wonder how many subjects the bot can speak about in as much depth.

Yes, these were some of my questions and concerns in my emails. No response to date.

I'd LOVE to have a bot like this that was on my local machine and NOT on a server in someone else's computer. The following conversation is really incredible!

Imagine if it (the bot) could learn or "know" a variety of subjects and not just be scripted with a story line.

I think it's about time to check in on Leslie Spring's Silvia once again to see what type of progress has been made with that program.

I also made a comment for Bruce Wilcox of Suzette fame but no responses to date either.

Anyone else have any bots / ideas, vids, let's share them!

Thanks for your thoughts guys!

UPDATE:

I have received a response and am waiting for permission to post.
Stay tuned! ;)

Emmett>> Actually, ejTalk is not about "chatbots". We are focused on the
elements of conversation; how to navigate and negotiate a conversation. We
use specific domain information to talk about. In the case of Hamlet it was
a structured data (xml document) that was a semantic "Cliff's Notes" on the
play: the cast, their basic relationships, key concepts/plot elements,
famous quotes, etc. In the case of the planets it was a list of things
(planets) and some attributes. For the planets she could apply generic
knowledge about lists to display and interact via voice and touch. The
specifics (planets vs. cities or restaurants or 'species of ants' or ...)and
other information that relates to those items in the list are supplied in a
structured xml file. So, she did not read Hamlet or astronomy books and
reason her answers. Chatbots seem intent on trying (and failing) to fool
people into believing they are a human. ejTalk is interested in automating
natural conversational mechanisms that make the conversation with the
machine conform to what people do naturally (ellipsis, indirect
confirmation, familiarity with the task, etc.)

Emmett>>> I have spoken with Leslie at conferences. Deixis and anaphora are
some of the things that we are making automatic. If you point to a planet in
the list and say "how far is that one from the sun?" Cassandra can
automatically combine the context with the conversational focus and responds
on topic. But if some time passed and we talked about some other things,
then she might attempt to verify if you were still "talking about Jupiter?"

Art>I'd like to know the type of program in which it is written? I don't

Emmett>>> No, Cassandra is not an AIML bot. She uses the ejTalker engine.
Her conversational behaviors are written in STEP files (and others) and much
of the power of the system is that it is that behaviors derive from more
basic behaviors and this derivation can go as deep (and broad) as desired.
Additionally, ejTalker has a number of mechanisms that support interesting
and appropriate variations in her interactions. For instance if you were
adding things to a grocery list Cassandra might use different phrases like
"put on" or "added to" your grocery list. If you were adding a series of
things she would notice that and shorten her responses on subsequent "adds"
just like a human would.

Art>> It would be nice to allow the bot / software to be for sale as a lot of
 practical uses could be realized by its use.

Emmett
>>> The ejTalker engine is currently being used to develop an
assistive agent product. And we are considering others. We are also working
on a webish version. We are working on the cloud issues now. Some of the big
issues are the speech input. The demos you saw use the speech recognition
that comes with the Windows opsys. It is used to great advantage for the
semantics of what was spoken (not just pattern matches like AIML). And the
TTS is a specific ATT voice that has nice qualities (and some quirky ones
too).

But we are working toward a "cloud" version to interact with ... and
hopefully with a big enough pool of serious/friendly users we can let her
learn and grow. That's the dream.

Art>At any rate, thanks for your time and all the best,

From the reply it seems to me that Cassandra is heading in the right direction, not classed as a chatbot and even more important not trying to fool the user into thinking they are talking to a human, spot on.

Thanks Art
