  • KRISTINA goes to the Opera

    July 29, 2017, by Mireia Farrús

    The time of the castrati in the opera, those classical male singing voices equivalent to that of a soprano, mezzo-soprano, or contralto by means of castration is far away. No one could imagine such a technique being carried out nowadays. Luckily enough, it was made illegal in the 19th century, coinciding with the end of the Baroque period and the incorporation of women in the opera.

    At this point, you might be wondering what the relationship between Baroque and KRISTINA is. So well, technologies have evolved so greatly, that we are now able to convert a male voice into a ...

  • Embrace the Unknown

    July 3, 2017, by Louisa Pragst

    Humans spent years of their life learning the meaning of words and how to respond to them. Even after we learned the basics, we never stop expanding our knowledge, with new, more sophisticated words and sentence structures or even by learning another language. We achieve this by permanently consuming and producing language over an extended period of time. Considering most dialogue systems do not spend years of practising with human conversation partners before they are deployed, how can they obtain the ability to hold a conversation?

    Traditionally, a dialogue system uses a predefined model that specifies everything the user and ...

  • Being KRISTINA: The Question Answering soul that drives the AI mind

    May 29, 2017, by lpmayos

    With the introduction of the first smartphone around ten years ago many people have come to grabs with a new kind of technology that surprised them, as they never thought that their lives would benefit from it as much as they did. The next surprise in this technological journey came five years later, when virtual assistants, a “fairytale” whose origins date back to the 60’s, were introduced in smartphones. It was not just an evolution, it was a breakthrough! Even more so when one considers that these assistants operate from a portable gadget that sits in the palm of ...

  • A better health assistance for migrants: family doctors will help us to evaluate the KRISTINA prototype

    May 12, 2017, by Chiara Baudracco

    Family medicine needs to be supported. Now, more than ever, communication technologies will help family doctors to improve their work especially when necessary to overcome linguistic barriers in order to ensure an effective and accurate assistance. The European Funded Project KRISTINA will develop and present a virtual assistant in the field of healthcare that will enable getting over language barriers when dealing with users and, therefore, its priority application will be to attend migrants who are struggling to overcome linguistic barriers. With the first prototype, KRISTINA becomes a conversation partner and during the last semFYC National Congress it has been ...

  • Standards in Kristina’s Avatar; Meeting between ARIA-VALUSPA and KRISTINA

    March 22, 2017, by lpmayos

    Last month, a workshop between the members of KRISTINA and ARIA-VALUSPA, another H2020 project on interactive virtual agents, was held in Dagstuhl (a computer science centre in the south-west of Germany). During this workshop several meetings to discuss different disciplines that creating interactive virtual agents involves took place.

    From a post of the ARIA-VALUSPA project (by Merijn Bruijnes):
    “The ARIA VALUSPA project (Artificial Retrieval of Information Assistants – Virtual Agents with Linguistic Understanding, Social skills, and Personalised Aspects) aims to create Artificial Retrieval of Information Assistants (ARIAs) that are capable of holding multi-modal social interactions in challenging and unexpected situations. The ...

  • The Kristina Social agent, the result of diversity and teamwork

    Jan. 30, 2017, by lstellingwerff

    The Kristina project aims at building a “"Knowledge-Based Information Agent with Social Competence and Human Interaction Capabilities". This is a pretty ambitious goal, but our current work is very promising in achieving that goal. Through diversity and teamwork, the agent is taking shape and starts to gain such competences and capabilities. And this is important, as the Kristina agent is going to be used to help people enhancing their lives, helping to bridge culture and language barriers and providing easier access to medical and health information.

    The Kristina project consortium consists of a broad set of partners, each with different ...

    Talking with machines like we do with humans it is a scenario present in many Science Fiction books, movies and TV series. Back in the 1960's Rosie, the home robot in the Jetsons, conversed with the family. And in the Star Wars series, C-3PO had very human expressions and could communicate with R2D2 who was not able to speak, but could understand spoken instructions. The computer in Star Trek was able to identify who was speaking and to understand voice commands for piloting the space shuttle. In most very recent movies, robots are hardly ...

  • Affective computing using Russell’s Circumplex model of affect

    Dec. 2, 2016, by Oriol Martínez

    Interaction between humans and computers has been increasingly growing during last 30 years [1]. Just think about how television, personal computers and, lately, mobile devices take an important role in your everyday life. Affective computing research aims to equip such deviceswith human-like capabilities to change the way we interact with them. In other words, we want automaticsystems that can recognize, interpret, process and simulate human affects with the final goal to emulatehuman empathy [2].

    In the KRISTINA project,we use Russell’s Circumplex model of affect [3] on both sides of the interaction pipeline: emotion recognition and emotion simulation.The ...
