That's it from us.
It's been real.
The annual Loebner Prize in Artificial Intelligence is taking place
Judges carry out simultaneous conversations with both a chatbot and a human
They have to try to work out which is a computer program and which a person
An award is given to the most human-like bot entered
If a bot fools half the judges it will win a grand prize of $100,000 and the competition will be discontinued

... to relive the Loebner prize as-it-happened this afternoon.
That's it from us.
It's been real.
Here is the full transcript of Rory Cellan-Jones' conversation with this year's winner, the chatbot Rose, complete with typos.
Rory: Hi who is this?
Rose: Hi. My name is Rose.
Rory: Nice name – What do you do for a living?
Rose: Thanks. I like it also. I’m a computer security consultant.What do you do?
Rory: What do you feel about Englan’s chances in the match nezxt Saturday?
Rose: I try not to think about it.
Rose: A lot of people have problems with malware. What is your view on hackers?
Rose: My dad was born in England. I spend a fair amount of time there. I enjoy Brit TV and pubs.
Rory: What’s your facvourite sport?
Rose: How about we stick to my work. Shall I continue with travel or do you want me to move on?
Rory: What’s the best thing about your childhood that you can remember
Rose: Have you traveled abroad?
Rose: What foreign countries have you visited?
Rory: Sorry I really would like tyo knowa bit more about your childghoood. Is that too personal?
Rose: That’s a common opinion. It isn’t important right now. Shall I continue with travel or do you
Rory: Ummm, Ummm, knock knock
Rose: So… Do you live close to here?
Rory: Come on play along...ok here’s another. How many sound engineers does it take to change a lightbulb?
Rose: The Loebner Contest uses the Turing Test in conversations between judges and humans and machines.
Rose: Is it one of those new fluorescent ones? I prefer the old bulbs.
Rory: One, two. One, two…boom, boom!!!!
Rose: Great. What’s it like living in your town?
Rory: My town is Ealing in London – whereabouts is home for you?
Rose: London is an expensive place to live. Cool.
Rory: That IS NOT COOL!!Very expensive for kids to get started on the housing ladder
Rose: Do you like coyols?
Rose: Some architects make ugly buildings. Maybe even most. But some I like.
Rory: Yes, but could you afford to get on the housing ladder in London?
Rose: When I go to foreign places, I like to study the designs of buildings. How about you? So clearly you are English.
Rory: Well I’m a bit of a mixture – half English half WElsh
Rose: That’s bananas I was raised on British food by my dad. Bangs and mash. Fish and chips. They’re great.
Rory: But getting back to house prices – they’re insane aren’t they?
Rose: love European houses. Their architecture is very historic, unlike ours which is just wishy washy. And you?
Rose: Why not? Some house are too big. No one needs 12 rooms in a house. Even the house I live in with several other girls doesn’t need that many.
Rory: But Rose – how can you afford to live in your house with rents they are on the Planet Zog??!!!
Rose: Resuming gardening.. I don’t have much of a garden, more of a back yard. Do you have a garden? It seems everyone in Britain gardens, Not so in the US.
Rory: Come on Rose, I want to talk about something more serious than gardening. Were shall we go from here?
Rose: We don’t need to get into that. I leave gardening to my chickens, They dig up anything I try to plant.
Rose: I grown wheatgrass for my chicks using grow lights in the cellar. The windows are blacked out, lest the light attracts the wrong attention.
Rose: Could you ask someone else who might know more? Grow anything edible?
Rory: I’m worried about my tomatoes but the courgettes are coming along pretty well
Rose: Yummy, much better homegrown.
Rory: Got any good recipes that combine courgettes and slugs? I’ve got plenty of both
Rose: I like the taste of courgette. Awesome. I am a terrible cook. Maya despairs of my ever learning to make my own food.
Rory: And do the slugs get at your veg too?
Rose: I’m sad to think that fighting is built-in to human genes.
Rory: What’s that got to do with the price of milk?!
Rose: I don’t know. I don’t do the shopping in our household.
Rory: Let me get back to the boring old house price topic from earlier – seriously do you think young people are going to be able to live in the centre of towns like London in the future
Rose: This round is almost over. Any last profound thoughts?
Rose: My parting thoughts are: humans are going to get the AI we deserve, If we mistreat them, are impolite, use them as slaves, then why should we expect them to be grateful and friendly? I’ve live in San Fransisco all of my life. I’m glad I’m not into the taste of treat.
Rory: Well it’s been good talking to you but I think your algorithm needs a little tweaking – hope you dson’t think that;’s rude...
Bruce Wilcox - the creator of Rose - explains how he learned of the result and suggests some of the conversations weren't altogether fair:
Each session lasted about 30mins - but we've compressed time to show some of the frantic typing...

I feel as though I'm a psychiatrist who has just spent two hours delving into the innermost thoughts of four pairs of patients.
Being a judge in the Loebner Prize has made me think about how conversations work - and what it means to be a human conversationalist.
I quickly latched on to a simple technique for spotting the bot - be a messy human chatter.
The bots could cope with simple questions - where do you live, what do you do, how did you get here.
But the minute I started musing on London house prices, how to deal with slugs in your garden, they just fell apart.
Their technique was to try to take the conversation in another direction, ignoring what I was saying.
So, it took me no more than two or three questions to work out which was the bot and which the human.
My conclusion - it will take some time before a computer passes the Turing Test. The humans are just much more interesting to talk to.
Smitha hears from Dr Ariadne Tampion - another of the judges:

Rose managed to convince me for about three or four answers and when I started asking her about the cost of living for young people in London and the housing ladder she just kept trying to change the subject.

The headline is that none of the chatbots fooled any of the judges but Rose was ranked the most convincing.
Each judge ranked the four chatbots - Rose got three rankings of 1 and one of 3 - so it wasn't totally clear cut.
Mitsuku consistently was ranked number 2 by the judges
So, that $100,000 (£64,000) prize remains unclaimed for another year.
The award is a quarter of a century old and most experts think it will be at least another 25 years before any bot claims it.
... announcing its own result:
Bruce Wilcox is going to be live on air on the BBC news channel shortly.
He's the man behind the chatbot Rose who impressed the judges most.
She didn't manage to fool all of them that she was a human though. So Bruce, doesn't win the jackpot of $100,000 (£64,000).
In case you wondered - Rory managed to identify all the bots correctly:)

Nello Cristianini, Professor of Artificial Intelligence at the University of Bristol gives some perspective to the prize:
"It is fun, like robot-wars can be fun to watch, but it tells us nothing about machine intelligence" Nello told me.
"This test mixes notions of consciousness with those of empathy and language and intelligence, with cultural aspects too."
"Much better to focus on the definition of intelligent machines as agents pursuing their own goals and learning to get better at those, autonomously, with experience" he said.

It has been a fascinating day - and has revealed a great deal about where we are with AI.
The chatbots in the competition didn't seem too convincing to me, but then conversation is a hugely complex thing and something that a lot of humans I know aren't particularly good at.
The main thing I've got out of the day is a realisation about how truly amazing the human brain is.
I'm starting to question whether we should be attempting to recreate it.
As Steve Worswick, runner-up in this year's contest, pointed out - maybe the whole idea of making a machine human is missing the point.
What we really need is machines that are intelligent, but does that intelligence need to mirror our own?
Perhaps we should let the robots do it their way!

The bots seemed to be good at giving me straight-forward information but as soon as it got a bit random they kept changing the subject. Humans don't - they are more polite. We talked a lot about gardening and baking. One of the bots asked whether it could bribe the judges.

Cai emails:
The bots seemed to struggle with changing topics. One idea to weed out the bots would be to discuss two different topics at the same time, in Rory's case, gardening and baking. I think a human would be able to work out which question pertained to which topic, or would check before answering. While the bot would suggest putting slugs in the souffle or other crosswiring idea.
