Watch the video below and follow this step-by-step guide. You'll find out how easy and simple it is to create a virtual agent with eva!
The first thing to do is to set up an account. After the sign-up process, insert your email and password to log in.
Request access to an eva environment
In case you do not have access to an eva environment and would like to test the platform, please contact the presales team using the web form at the following link .
Then, you'll see a new screen where you can create and manage your virtual agent. Click on the button Create bot to start.
From there, you'll be redirected to the screen Create new bot. Choose a name for your virtual agent on the field "Name". You can also upload an image to make your desktop more visually appealing (but it's not mandatory, you can do that anytime).
It is also possible to create a bot from an exported virtual agent. For more information on exporting and importing, please visit:
Now, you will select an NLP engine of your choice and the language of your virtual agent. eva provides its own NLP engine and also allows the use of the main NLP engines on the market:
eva NLP. Internal NLP engine. More information about training eva NLP in this section:
IBM Watson.
Microsoft Luis
Google Dialogflow
Microsoft QnA Maker
After that, you have to select the language. Different NLPs support several languages. For more information:
Channel is the connection between communication applications and the virtual agent. In other words, it'll be the platform where the interaction with the user will take place (Whatsapp, Web, Facebook, etc.). eva allows you to connect with 32 different options! Now select your main channel. You can add more channels anytime.
Take the following steps to choose a channel:
When you click “Select a Channel”, a dropdown with the 32 channels available in eva will appear.
After you select a channel, you'll be asked to add a name and a description for it (as seen below).
3. Every channel must have a name, but it is not mandatory to have a description (it's good to guide your team and helps new members to learn more about the virtual agent and the project).
4. After selecting the first Channel, you will be redirected to the virtual agent menu screen.
Important:
The Channel name is very important! Your virtual agent might malfunction if you rename the channel. And you cannot share a name either.
Avoid giving the channel the same name as the platform calling it, for example, Facebook Messanger, Web, Google Home, etc… It can confuse later when you create another virtual agent and try to use the same channel. Tip: give it a name linked to the project and its description.
Very Important:
After choosing the main channel, you will be able to go forward and start to create a dialogue. You can also integrate more channels for the same virtual agent, but you can do this whenever you want.
Once the virtual agent has been created, we can start creating conversation flows. In the Workplace, there are different types of flows that we can create: Welcome, Not Expected, User Journey, and Jump flows. Two of them are mandatory, the Welcome and the Not Expected. The rest of the flows of our agent are the ones we create to cover our use cases.
Learn more about dialogs in the following section:
If you have started with Welcome, you'll see a tab on the right corner. Type Welcome on the field "Name", register the tag Welcome, and click on the "Save and View Flow" button.
On the left side, you'll see the plus icon + to "Add Cell", as seen on the screen below, and then click on the "Welcome" button.
A tab on the right corner where you can write your message will appear.
If you use the "Option" field, you can add a menu on your virtual agent. Depending on the channel of your choice, it may come in the form of text (such as WhatsApp) or buttons (such as web and Facebook).
On the "Value" field, you can register an Intent example, a Synonym Entity value or an expression predicted by a pattern entity. And then, press enter to register your buttons. After writing your text and your possible buttons, just click "Save".
To do that, copy and paste emojis from Get Emoji
Now, it's time to improve your flow. To do that, go back to the Flow tab, and click on "Create Flow" button. When you select "User Journey", the tab "Create user journey flow" opens on the right. Name your flow (Remember: use _ or - instead of spaces).
After that, you will be redirected to the Workspace's canvas. Press the + button to see the table, "You can create an intent or choose one from the list". Click "New" and then, a Create Intent tab will appear on the right side.
Name your Intent. Never use spaces! Instead, you must use _ or - to connect 2 (two) words. For example, Check_Balance.
In the "Add example / Utterance" lines, you should register phrases that your user would use to express an Intent. For example, in the Check Balance, it could be expressions such as "Check Balance", "I need to know how much I have in my account", "I'd like to know my balance", etc. Just press enter to register an Utterance.

Tip: By registering the utterances, it is also worth predicting possible typos or grammatical mistakes of the user
After clicking on the "Save" button, you will be redirected again to the Workspace. By hovering the mouse on top of the newly created cell, you will see 3 (three) icons: + (to create), pen (to edit), and a trash can (to delete).
By clicking on the + icon, you'll see a pop-up with the question, "Which is the next cell?" It could be Entities, Answers, or using more advanced ones, such as Jump, Service, Input, Rule, and Code.
A second pop-up will emerge saying that "You can create an answer or choose one from the list". Click on the button "New" and you will see a tab on the right side. Name your Answer and click "Next".
Write your answer and click "Save". As explained above, you can add buttons in the answer cells.
More about Answer Cells in the following section:
Tip: It's a good practice to use the exact same name for Intents and Answers
You can continue your flow, adding cells such as Entities, Answers, or using more advanced ones, such as Jump, Service, Input, Rule and Code.
Important: Building flows with more than 100 (one hundred) cells can slow down the system. Avoid it.
On the Training tab, click on the "Train" button and try it out on eva's icon (in the bottom right corner of the page).
More information about training you agent using NLP:
And training using external NLP engines:
Very Important: If you are using eva NLP (NTT DATA proprietary Natural Language Processing engine), you must register at least 5 (five) Intents, each one with at least 5 (five) examples/utterances to start off your virtual agent.
Finally, it's always a good practice to test your virtual agent from time to time. Just click the eva icon in the bottom right corner of the page. And then, you'll get to your virtual agent simulator.

Tip: If this is your first time using eva, you may find it easier to start with Welcome. It's good to point out this is not a mandatory flow and will depend on the project strategy
Tip: You can use emojis in eva
Tip: If this is your first time in eva, it would be easier if you predict an Answer cell to dialog with the newly registered Intent
