Julie: Behind the scenes! [Infographic]

This article is an updated version and was originally published on november 2016.

“Julie who is CC’d in this email will contact you to schedule the meeting”

Ah! Where would we be without her? Even though she is an integral part of your daily life, we haven’t really taken the time to fully introduce her to you have we? Let’s fix this right now: come discover what goes on behind the scenes of Julie through this infographic display. You can print it and showcase it above your desk, share it with your friends… the possibilities are endless.

A self-aware intelligence…

If we go back to the definition and origins of the term intelligence, Wikipedia, the king of definitions tells us this:

“The term derives from the latin verb intelligere ( “ability to understand”), whose prefix “ inter- ” ( “between”) and stem legĕre (“to collect, to gather) or ligare (“to bind, to unite”) essentially suggest the ability to bind elements with one another.”

Indeed, the main challenge that Julie faces is to succeed in combining the different elements found in the emails she receives so that she can not only understand them but also process them successfully. This explains why she requires her own thinking capacity, developed through artificial intelligence (AI) and particularly the two following features:

A large number of computing programs exist inside Julie’s core but that’s not the end of it. All these programs have to be created and modeled by humans. The way we interact in society and in this particular case, the way we schedule our different appointments respond to a specific set of well established codes transmitted between generations and therefore must also be transmitted to machines.

In Julie’s case, all three founders initially “divided” the appointment scheduling process into several steps. In other words, they analyzed the act of scheduling a meeting in all its little steps. To do so and to fully understand how scheduling a meeting works, they, themselves, took upon the role of assistants 24/7 for a duration of 6 months and came up with the following steps:

  1. New request
  2. Answer questions WHO? WHAT? WHEN? WHERE?
    1. Who is making the request?
    2. What is the request?
    3. When will the appointment take place?
    4. Where will the appointment take place?
  3. Make the appointment
    1. Send available dates
    2. OR send an invitation for the appointment

Each step is divided into sub-steps, precisely in sub-questions to which Julie must find an answer in order to move forward in her decision tree and finally carry out one of two actions: Send an email OR create a new event in the agenda.

Excerpt from Julie Desk’s decision tree

In the end, Julie’s AI brain contains 4 main components:

It is evident here that the human component is essential to the development of an AI.

… And a great expertise

The different blocks integrated into Julie’s core allow her to develop a whole set of skills and know-hows that are essential to an efficient virtual assistant when it comes to appointment scheduling.

Let’s analyze in depth all these know-hows.

Information retrieval

In order to understand the emails that she receives, Julie needs to fully “understand their meaning”. For that to happen, she carries out several information retrieval tasks such as:

Here is an example to illustrate this:  

“I would like to schedule a meeting with Julien for Friday 16th July 2017 at 2.30pm in his office”

The following “Friday 16th July”, “2.30pm”, “in his office” are respectively named entities of date, time and location.

Automatic Classification

As mentioned in our previous post How NLP gave birth to Julie, to allow her to process the requests she receives, we have defined several tags linked to appointment scheduling that she has to associate with each request: “Lunch”, “Call”, “Interview”, “Meeting”… Julie uses around ten tags to categorize the appointments that she processes. Each one corresponds to a different type of appointment.

This classification allows for Julie to assign these various tags to the data she receives and extracts from emails.

Bilingualism

Did you know that Julie is bilingual? She understands English just as well as she understands French. Once you understand the complexity of all the different analysis and information extracting processes, you quickly realize that being bilingual isn’t irrelevant, especially where NLP is concerned.   

Constant learning

Just like we learn from our experiences, successes and failures, Julie also needs to continuously learn and evolve through feedbacks from not only her users but also her “coaches” who are our operators. As we have mentioned before, it is also a part of the learning process.

The big difference that exists between Julie and other intelligent agents is that we do not believe in a 100% automatic technology to manage the appointment scheduling: language constitutes such an immense and complicated field and more often than not, we tend not to act in a logical manner. At this point in time, it is difficult, if not impossible for a machine to respond to 100% of a user’s requests without making any kind of mistake. On the contrary, we believe in combining both humans and machines to create efficient and increasingly powerful models and thus revolutionize the role we play in society and the way we live.

In that sense, Julie is a supervised intelligence.  

Each action carried out by Julie is submitted to operators who will complete, correct and validate it. There are like teachers who give out an average grade. That way, Julie is able to understand how she conducted her task well and continually seek to improve herself. This is the last step we mentioned in Machine Learning, the optimization step.

Machine Learning – the Optimization step


The more you use Julie, the more she improves 🙂

But what about the security of my data?

As you may have noticed, data plays a key role in the process of machine learning. But rest assured, Julie won’t be doing whatever she wants with your data!

What is the data stored by Julie Desk?

When you sign up for Julie Desk, you connect her to your calendar. This means that you give Julie the right to read and write on your calendar. Julie can also see the times that you are available and program your meetings depending on your availability (and your preferences of course).

In order to make these requests to Julie, you will have to send her the information by email or by putting her on copy of an email. These emails are also archived. We only have access to the information you have decided to send or transfer to Julie and only archive emails that she receives directly from you. In the same vein, we have no access to your inbox or contacts.

Where is the data stored?

We work with OVH, certified ISO27001. We house our services and data in a dedicated database in France.

We are also in the process of obtaining a ISO27001 certification and are working on conforming to the new GDPR regulation (in place by May 2018).

Who has access to the data?

Julie:)
As mentioned before, Julie is a supervised AI program. Julie’s “coaches,” the operators we mentioned, have access to the data. Access to data is controlled and only possible under certain conditions. To learn more, contact us.

What is the data for?

Julie uses the data for two things:
