BACKGROUND

Introduction

Lillian is a virtual librarian. She is designed to answer user queries about books, and particularly library holdings. As well as being able to tell a user if a library holds a particular book she can also:


  • Deep link them to the library's own holdings page for the book, which may have availability and reservation data

  • Direct them to another library that holds the book if the local library doesn't

  • Direct them to the right page on Amazon if the book is not held

  • Advise them of books by a particular author held

  • Advise them of books on a particular subject held

  • Tell them what the book is about

  • Tell them what other people thought of the book

  • Tell them what books people like who also liked this book

Lillian combines:


  • The Discourse™ Natural Language Interface and Chatbot engine from Daden Limited

  • The Sitepal™ animated avatar and text to speech system from Oddcast Inc

  • Web services interfaces from:

    • Talis

    • Amazon

    • OCLC

Lillian is a web native, web delivered application, requiring only a browser with the Flash plug-in installed to work (Flash plug-in only required for avatar and text-to-speech).

The current version of Lillian is only a proof-of-concept. As such she lacks the security, resilience and error trapping that would be found in a production system, and only implements some of the knowledge cases which would be required in a publicly accessible system.

Lillian can be found at:

http://www.daden.co.uk/chatbots/livebots/lillian/

A text only version is also available for low-bandwidth use.

Lillian was originally built for Talis' Mashing Up The Library competition.

Note: Lillian is intended as a proof-of-concept only and does not yet cover every possible combination of input question and web service response, however addressing these issues is mainly a case of developing more question/response cases rather than writing new code.


Charlotte - Your Talking TV Guide

charlotte.jpg

Talk to Charlotte

Charlotte is a talking TV guide. She can help users find out what is on TV, when their favourite programme is on, or when their favourite type of programme is on.

Charlotte is implemented as a chatbot. She uses our standard SpeechBot engine but with two important additions:

  • a set of AIML cases which are used to pattern match the users request, eg "what is on BBC1 tonight". Essentially a natural language query interface
  • a bespoke module designed to provide a standard interface for the AIML to the BBCTVAPI TV schedule web service.

While Charlotte is presented here with an animated avatar and text-to-speech, these are just one specific interface style. The application will with just a set of plain text dialogue boxes.

Channels

Currently Charlotte only has access to BBC 1 and 2 for generic queries (eg what's on tv), but she can also access all BBC channels for channel specific queries.

The BBC web service is updated every day and stores the next 7 days' data.

Charlotte can also use the standard TV Anywhere format we can implement Charlotte for any TV or radio station or network which makes its programming information in this format, or as a web service. Please contact us for details.

Queries

Charlotte can accept questions in a wide variety of phrasings. Some of the phrasing she supports are:

What is on tv tonight
What is on tv tomorrow
What is on tv monday
What is on tv _
What is on tv on monday
What is on tv this morning
What is on tv this afternoon
What is on tv this evening
What is on tv on _ morning

Are there any _ programmes on the (tv box) tomorrow
Are there any _ programmes on the (tv box) this evening

... where _ is a wildcard standing for the channel, date, time, programme or tag.

Responses

A real challenge is how to present what could be a large amount of data in a conversational style. The approach that Charlotte takes is to extract the 3 or 4 longest programmes for any desired request - on the basis that these are likely to be the most useful responses. Of course it does have its drawbacks when BBC News 24 kicks in at midnight...

Bugs

Charlotte is currently only a demonstration system, so we know there are a few bugs lurking in there. Any major ones we'll report here.

  • Charlotte gets confused by repeats at the moment since they share the same CRID (at URL for the programme). We'll fix that soon.

Future Development

Things we'd like to do to improve Charlotte still further include:

  • more natural phrasing when listing out long results lists (eg neighbours is on monday to fridat at 12.30 and 6.45).
  • better use of keyword searches against the programme tags
  • even more natural language patterns

Charlotte is supported by BBC Backstage.

NewsBots

  • Your own virtual newscaster
  • Engage your visitors and get word-of-mouth promotion
  • High quality speech
  • No specific client plug-ins or downloads
  • Simple to integrate on your web site - just one HTML tag

Make your web site stand out from the crowd by having your very own virtual newsreader, reading out your news and latest information 24x7 to visitors to your web site.

NewsBots are talking, animated avatars that take the contents of a news feed generated by your web site, and read the news out to your visitors. They catch the eye, and ear, and such avatars are proven to increase visits by up to 200%, and sales by over 25%.

Supported Feeds

NewsBots are designed to work with any of the standard feeds produce by today's content management systems. NewsBot supports the RSS, RDF and Atom standards. These feeds can provide your latest news, web site changes, events, product updates, or almost anything that you want to put in them. And if you don't have such feeds enabled from your web site, then we can generate them for you from your existing web pages.

Integration

Since NewsBots are provided as a web delivered application they need the absolute minimum of integration with your existing web site. In fact most installations need only a single <OBJECT> tag. The avatar can be sized to fit whatever space you have available, and the look and background tuned to match your site.

Language Support

Whilst our demo only supports english language feeds, NewsBots can be used with feeds in a variety of languages - but we need to configure the relevant text-to-speech language voice for you. Languages that we currently offer include French, German, Spanish and Canadian French.

Benefits

NewsBots help to make your web site stand out from the crowd, helping to increase visits, retention, and ultimately sales. If you already have a newsfeed on your site NewsBots are the ideal way to make the most of that investment.

Chatbots and eBay

This page provides you with a step-by-step guide to using SitePal avatars on eBay. Whereas users of eBay.com can do a lot of this automatically, eBay.co.uk users need to do some manual cut-and-paste - hence this guide.

The Basics

Putting an avatar onto your eBay pages will help your auction to stand out from the crowd. Ebay users have reported that using avatars can increase sales by up to 25%, and that SitePal enabled sales close higher than other auctions. The avatar can greet every users who looks at your item page with an audible description of the item, information about you the seller, or even play some related sounds or music (copyright willing).

The SitePal Account

The first thing you need is a Sitepal account. Sitepal do 3 types of account, Bronze, Silver and Gold. The first decision is do you want to use recorded speech (for best quality) or text-to-speech (for greatest flexibility). We'd recommend the latter which mans you need a Silver Account ($199 pa). If you're happy to record a new message for each auction (or group of auctions) then you're OK with the Brozen account ($99 pa). Set up your account by clicking here. Note: If you are using eBay.com and want to use Sitepal's automated set-up you'll need a Silver Account - for eBay.co.uk users Bronze is fine.

Planning Your Avatars

Before you design your avatar think about how you are going to use them. With your account you get a number of avatars (5 for Bronze, 10 for Silver). Each can look different, and each can have a different message. You might decide to give them all the same look, but different messages. You might decide to create a unique message for each item you sell (in which case you will be updating the avatar quite often), or use a more generic message (eg "this is a great book" rather than "The Da Vinci Code" is a great read"). Don't worry though, you can redesign avatars and change messages as much as you like for no extra cost.

Designing Your Avatar

Sitepal provides you with the tools to design each avatar, starting from a basic template, changing clothes, colours and backgrounds (you can upload your own images for this). If you are using recorded speech you can upload a separate recording for each one. If you are using text-to-speech then you can type in a separate message for each one.

To set a text to speech message click on the Audio tab top left and then on the Add Audio button.

Then select Text-to-speech from the pop-up dialogue, and then type in your text, choose a voice (visit our web page to hear the voices), and give the message a name. If you're using recorded speech then follow the instructions on the SitePal web site for that.


Make sure the message is selected (i.e. has an orange border around it) before you save the avatar.

Finish your design and save the avatar.

Manually Embedding In eBay - Step 1

OK, now for the tricky bit. From your avatar list click on the "Embed in HTML eBay" button (NOT the Publish to eBay button - that's for eBay.com only) for the avatar that you want to use for a particular auction.


From the next screen click on the HTML Only tab.

Then select all of the text in the main white box (the text usually starts <OBJECT...). You must make sure that every piece of text in the box is selected - ie. shows as white on a blue background. The simplest way of doing this is to just left click in the box and then press CONTROL-A on your keyboard.


Finally copy all this text to your clipboard (CONTROL-C or your preferred method). You can now click on CLOSE as you are finished with Sitepal.


Manually Embedding In eBay - Step 2

With all that text still on your clipboard, open up your eBay account and go to the item that you want to use the avatar on. Open it for editing, then go to the Add Description section and just paste (CONTROL-V) all the text from Sitepal into the section. That's it. Done. Preview your item and you should see the avatar and hear the speech after a few seconds delay. Finally test it "buyer side" and that should be that.

Note: If you are using an auction management system then the method should work just as well. Just paste the Sitepal text into wherever you normally put your description text. You can also put the Sitepal text into tables if you want the avatar say right justified and your description text left justified.

If things don't work

The Sitepal service is pretty reliable, so if you have problems they are more likely to be yours rather than Sitepal. The main things ot check are:

- did you copy every last character across from Sitepal?
- have you chosen the right message for the avatar you are displaying?

Counting Streams

With each Sitepal account you get a number of streams. A stream is basically your avatar reading out your message once. This means that if your item descriptions are typically viewed say 20 times in an auction, then you'll be using up 20 streams for every auction that you use Sitepal on. It doesn't matter how many avatars, how many items or how many times you've changed the message, every "hearing" of a message counts as one stream (even if a user re-loads the page!).

Bronze accounts get 12,000 streams a year, silver 30,000 streams and gold 102,000 streams a year. On the basis of 20 streams per auction that means that Bronze accounts will support 600 auctions a year, Silver 1500, and Gold 5000 auctions a year. If you find yourself reaching your stream limit you can always buy additional streams at $4.95 per 1000 streams - you don't need to upgrade the account. Overall we reckon that for a Silver account every view of your SitePal enabled eBay page will cost you less that half a penny!

So what are you waiting for? Set up your SitePal account and get better results on eBay now!

Chatbots General Questions



Technology Questions


What software do I need to install on my servers?

All software is run either on our servers or those of our technology partners. Other thank links of simple lines of HTML or javascript code there is no need to load new code onto your servers.

What software do my customers need to install on their PCs?

Our textbot needs no extra software. Our avatar based chatbots only need clients PCs to be able to run the standard Macromedia Flash plug-in. Most customers will already have that installed. If not they can download and install it in minutes.

Can chatbots be accessed when mobile?

It is feasible to run an avatar chatbot over a GPRS or dial-up GSM link, but not advisable. For this reason we suggest making a textbot available for mobile users. Avatars should run OK over 3G networks. We currently only support avatars on Microsoft based PDA, not Palm or mobile phones. We can recommend other technology solutions for these devices.

How well does a chatbot work over a dial-up connection?

Avatar chatbots need decent bandwidth to download the speech component. Whilst they will work over dial-up performance will not be ideal. Clients should consider offering text chatbots to supplement avatar chatbots for low bandwidth clients.

What speed of broadband connection is required?

Avatar chatbots work fine on anything over 128 kbps.

Do chatbots work through firewalls?

Because our chatbot use Flash rather than streaming audio or video they will work fine through almost all corporate firewalls.

How do you use cookies?

We only use cookies to stop pagebots repeating the same thing when a customer returns to the same page in the same session.

What browsers do chatbots support?

Since the chatbots place no special demands on the browser beyond the use of Flash they will work on most browsers. We have tested them on IE5/6, Mozilla, Firefox and Opera, and on PCs and Macs.

Can you turn the sound off?

If you want to let customers turn the sound off then this can be done through some simple javascript - with their preferences being saved by a cookie.

Do chatbots work over the phone?

No, chatbots can currently only be accessed through a graphical web terminal. However we do have a product which we will be laucnhing shortly which gives you phone access to chatbot content.

Will the chatbots work on standalone computers?

No. our chatbots are web-native applications designed to work over the Internet. We do have access to standalone chatbot solutions which may suit some applications.

Will the chatbots work on Apple Mac computers?

Yes. Sine they only need a standard browser and Flash support there is no problem in running them on Macs.

Product Questions


What types of avatars are available?

We provide a range of basic avatars, which you can then tailor by changing clothing, colour, hairstyles etc. Adult and child avatars are available.

Can I have a custom avatar designed?

We can provide a custom avatar design service, starting at $5000.

Do avatars have to be human?

No. With our customer avatars they can be anything you like, animals,aliens, shapes, or even talking products.

What voices are available?

You can try our voice samples out for yourself. We offer UK and US English, male and female, as well as German, French and Spanish.

Can I have a custom voice recorded?

Custom voices are only feasible on FAQBots and PageBots. Whilst you will get a completely human voice, you will also lose the flexibility of using Text-to-Speech. And our TTS voices are very good.

Can I record my own speech?

Whilst you will get a completely human voice, you will also lose the flexibility of using Text-to-Speech. And our TTS voices are very good.

Why not use video or recorded speech instead of a pagebot or sitebot?

Flexibility. By using text-to-speech and animated avatars you can instantly change the responses or speech without having to re-record anything. This also means that the responses can be totally dynamic, driven by current stock or pricing levels, or just what's on the news.

Why not use another chatbot like ALICE or Sourceforge?

Whilst these chatbots may be great at chatting, they are significantly lacking in interfacing or commercial focus. Our chatbots are designed to be able to interface with a wide varity of information sources, and to be able to conduct business orientated tasks, such as seeking particular pieces of information or conducting survey. Leave Alice to the laboratories.

How do you capture data to program a chatbot?

We can capture data in a wide variety of ways. We have a simple data format for bulk import, and can provide tools to help import data from any standard data exchange format such as CSV, or Excel. We are also developing "harvester" tools which let the chatbot learn from existing pages of text.

Can a chatbot interface with an existing IT system, eg stock control, pricing etc?

If a system is available through a web interface then we can probably interface our chatbots to it. Our ideal approah is to use an XML based interface, such as an RSS feed or a SOAP interface. If this is not available we can simulate an HHTP GET or POST call and then "screen scrape" the data.

What types of chatbot can you provide?

Read our product pages for full details. Our main "packaged" bots are the FAQBot, PageBot, TextBot, SpeechBot and AIBot.

What languages do you support?

We currently support english, french, german and spanish. Of course you need to programme questions and answers in each language.

What modules are available?

Read our module pages for a full list. Modules let us significantly add to the chatbots functionality - and are what let our chatbots really differentiate themselves from Alice type chatbots.

How many cases do I need to fully programme a chatbot?

This is only an issue for the true chatbots - our TextBot, SpeechBot and AIBot. We think that 100 - 200 cases will cover most of the basic needs. If you have a large product range then we would look to develop a generic interface so that the chatbot can answer questions (e.g on pricing, availability, colours, dimensions etc) without needing to be explicitly programmed on every product.

Should I put a PageBot on every page of my web site?

It's up to you. We normally suggest starting with just the top level pages unless the site is very small. You can then decide where else you want to put PageBots to add emphasis.

Commercial Questions


How much does a chatbot cost?

Visit our product pages for outline pricing. Chatbots are highly affordable, starting at only £499, a fraction of the cost of a new web site. Full pricing details are available on request.

How long does an installation take?

Assuming you have the data readily available there is no reason why a PageBot or FAQBot shouldn't be live within 4 - 6 weeks. We could probably even do it in a week if you're up against a deadline. The proper chatbots take longer as their is more data to laod, and more cases to be considered. Reckon on 8 - 12 weeks for a typical project.

What support do you offer?

We offer a variety of support options following a typical Bronze/Silver/Gold scale, and ranging from 5 day, working hours email support to 24 x 7 options telephone and on-site options. Call us for details.

Accessibility Questions


Are chatbots useful for visually impaired users?

We think that chatbots can offer significant benefits to blind and visually impaired users. Whilst the graphic avatar is of little use, the speech and chat interaction can provide a far more usable interface to yur web site for many users than using a full-blown screen reader such as JAWS, or a simple etxt-to-speech application such as Dragon Naturally Speaking. Indeed even learning impaired users may find the chat interface an easier way to work their way around your site.

Can a chatbot be lip-read by a deaf user?

No, or at least we don't think so. Whilst the mouth moves in sync to the speech we don't beleive its good enough for lip-reading.

Can I talk to a chatbot using speech-recognition software - such as ViaVoice or Dragon Naturally Speaking?

Yes. We have tested Dragon out in our lab and it works suprisingly well. We are adding extra commands to the chatbot to make life easier for speech-rec users. The only downside at present is you need to use a headset to stop the speech-rec trying to read what the chatbot is saying.

Does putting a chatbot on a site fulfil my accessibility requirements?

No. Chatbots are an extra feature on your site. You should also be aiming to make the whole of your site accessible by following the W3C Web Accessibility Initiative guidelines.

Chatbots General Questions


Is a chatbot a real artificial intelligence?

No. Whilst the Turing Test is always talked about as the measure of artificial intelligence it is really just a measure of a good chatbot, not a true AI. And even Alice and other academic chatbots are still far short of winning the Turing Test. Download our white paper for more information.
