Title : An Empathic Agent that Alleviates Stress by Providing Support via Social Media

Presenter Lenin Medeiros
Abstract I am going to talk about what I have done so far in my PhD as well as the current status of my work. During my PhD research I am developing an ‘artificial friend’, i.e., an intelligent agent that provides support via text messages in social media in order to alleviate the stress that users experience as a result of everyday problems. The agent consists of three main components: 1) a module that processes text messages classifies them into categories of problems, 2) a module that selects appropriate support strategies based on a validated psychological model of emotion regulation, and 3) a module that generates appropriate responses based on the output of the first two modules. The application is able to interact with users via the social network Telegram.

Title : The Semantic Frontier: Going Where No Triple Store Has Gone Before

Presenter Wouter Beek
Abstract In the first decade of its existence, datasets from the LOD Cloud have been stored, indexed, and exposed in triple stores that implement (some subset of) the SPARQL standard. While these triple stores are useful for some purposes, in recent years we have seen an increasing number of Linked Data use cases that do not work well with -- and that may ultimately not depend on -- the traditional SPARQL paradigm. Examples include big data processing, graph navigation, cost-effective publishing, machine learning, and empirical semantics. In this talk I will give a brief overview of where HDT and ClioPatria development is heading today, and what are the main use cases that it seeks to enable. I will specifically delve into the use case of empirical semantics, where we wish to determine the meaning of expressions empirically (rather than by analytic means). I will focus on the challenges that we face when studying semantics empirically, and how we can overcome these challenges by pushing forward the 'semantic frontier'.
