Research Unit in Logic, Language and Information (Andalucia Tech)
UILLI - AT
The research network UILLI-AT is a coordinated Research Unit that incorporates other labs/research teams within
University of Seville and University of Malaga.
Its main objective is to promote collaboration through the realization of great research projects that require
the active participation of multiple researchers in various disciplines. These fields include the following:
- Logics and Philosophy of Science.
- Computer Science and Artificial Intelligence.
- Mathematics applied to Computer Science.
- Cooperative Information Systems.
- Other convergent fields, like Robotics and Domotics.
The unit is fully operative and is currently involved in the research Project "New Design of Dialogue Systems"
with a focus on the study of the techniques for the application of new approaches to the design, implementation
and evaluation of Dialog Systems.

Explora Research Project
New Design of Dialogue Systems
Dialog Systems (DS) that are oriented both to spoken and written interaction represent one area of
major economic impact and scientific interest in the field of Language Technologies. To design a DS is
a highly complex process that must integrate operative functional requirements (what to do and how),
linguistic issues (natural language) and computational elements (response times must be extremely
The main research lines have been lately focused around the study of the techniques that allow for the
quasi-automatic creation of such systems from training bases (annotated corpora), while addressing
open domains (one of the present-day objectives is precisely the idea of universal domain). Having
into account the main goals of the Explora program (exploration and investigation), researchers from
different teams raise the following question: How the analysis of human language learning can inspire
the creation of a model applicable to the design of dialog systems.
The first observation to be made in our proposal is the abductive nature of language learning, the
temporal and epistemic characteristics of such process and the existence of cognitive and metacognitive
phenomena that come along and could be spread to modulate DSs. This Project must
therefore be considered an exploratory one that can allow for the development of a formal framework
that may produce a dynamic design of a DS. This project is endorsed by the collaboration of researchers
from different teams in all related fields: Advanced Dialog Systems (UGr), Logic, Language and Information (US),
Cognitive Sciences, Applied Mathematics and Computation and InDoMiTo (UMA).
A Research Platform for Conversational User Interfaces
Innovative research on hot topics related to New Design of Dialogue Systems requires the use of Advanced platforms for the implementation, use and evaluation of Conversational User Interfaces. In order to optimize the available resources of the research project and streghten the collaboration between the accademic and industrial sectors, the aforementioned Explora project will use the Lekta.ai technology as a reference working platform.
Lekta version 2 is the result of several years of intensive research on Spoken Dialogue Systems and Conversational User Interfaces. It follows a multidimensional approach integrating the computational linguistic dimension, with the operative, communicative and business factors involved.
In addition, Lekta follows a hybrid approach that facilitates the integration of knowledge, business-oriented and strategic-driven operational and communicative strategies. This hybrid approach also guarantees the optimization of the whole architecture by means of machine learning, and data science-based techniques.
Lekta.ai is currently working on version 3 of the technological platform, integrating some of the key research trends in the field, such as incremental understanding and dialogue management, an open-domain approach able to improve the reusability of language resources, application of deep learning to dialogue management and error handling, etc.
Jose F Quesada is the director of the Andalusian Scientific Information System (SICA), Associate professor of the Department of Computer Science and Artificial Intelligence of the University of Seville, coordinator of the Club Scratch Iberciencia (Secretary of Science - Organization of the Iberoamerican States - OEI), and has served the European Commission as well as the COST organization as an Expert Evaluator since 2013.
He got his Doctor degree in Computer Science degree from University of Seville in 1997, BA in Philosophy from the University of Granada in 1992, and BA in Art History from UNED in 2013. After a PostDoc at SRI (Computer Science Lab, Menlo Park, CA), he participated in several Spanish and European Research Projects. From 2005 till 2012 he was the Research Director of the Natural Language Division of Vocalcom. In 2016, he has co-founded the company Lekta.ai, where he is leading the research and innovation programs as the CTO of the company.
His present research interests focus on the integration of Language Technologies, Machine Learning and Data Science. He has published more than 80 papers in different journals and conferences, and has participated in more than 100 industrial events related with language technologies.
