Social talk capabilities for dialogue systems

Small talk capabilities are an important but very challenging extension to dialogue systems. Small talk (or “social talk”) refers to a kind of conversation, which does not focus on the exchange of information, but on the negotiation of social roles and situations. The goal of this thesis is to provide knowledge, processes and structures that can be used by dialogue systems to satisfactorily participate in social conversations. For this purpose the thesis presents research in the areas of natural-language understanding, dialogue management and error handling. Nine new models of social talk based on a data analysis of small talk conversations are described. The functionally-motivated and content-abstract models can be used for small talk conversations on various topics. The basic elements of the models consist of dialogue acts for social talk newly developed on basis of social science theory. The thesis also presents some conversation strategies for the treatment of so-called “out-of-domain” (OoD) utterances that can be used to avoid errors in the input understanding of dialogue systems. Additionally, the thesis describes a new extension to dialogue management that flexibly manages interwoven dialogue threads. The small talk models as well as the strategies for handling OoD utterances are encoded as computational dialogue threads

EEG Mode: emotional episode generation for social sharing of emotions

Social sharing of emotions (SSE) occurs when one communicates their feelings and reactions to a certain event in the course of a social interaction. The phenomenon is part of our social fabric and plays an important role in creating empathetic responses and establishing rapport. Intelligent social agents capable of SSE will have a mechanism to create and build long-term interaction with humans. In this paper, we present the Emotional Episode Generation (EEG) model, a fine-tuned GPT-2 model capable of generating emotional social talk regarding multiple event tuples in a human-like manner. Human evaluation results show that the model successfully translates one or more event-tuples into emotional episodes, reaching quality levels close to human performance. Furthermore, the model clearly expresses one emotion in each episode as well as humans. To train this model we used a public dataset and built upon it using event extraction techniques(1).info:eu-repo/semantics/publishedVersio

Culture and disaster risk management - stakeholder attitudes during Stakeholder Assembly in Lisbon, Portugal

This report provides a summary of the topics discussed and the results of the third CARISMAND Stakeholder Assembly conducted in Lisbon, Portugal on 27-28 February 2018. In order to promote cross-sectional knowledge transfer and gather a variety of attitudes and perceptions, as in the first and second CARISMAND Stakeholder Assemblies held in Romania and Italy in the previous years, the audience consisted of a wide range of practitioners who are typically involved in disaster management, e.g., civil protection, the emergency services, paramedics, nurses, environmental protection, Red Cross, firefighters, military, and the police. Further, these practitioners were from several regions in Portugal, including the island of Madeira. The 40 participants were recruited via invitations sent to various Portuguese organisations and institutions, and via direct contacts of the Civil Protection Department in Lisbon which is one of the partners in the CARISMAND consortium. The event consisted of a mix of presentations and discussion groups to combine dissemination with information gathering (for the detailed schedule/programme see Appendix 1). Furthermore, this third Stakeholder Assembly was organised and specifically designed to discuss and collect feedback on a comprehensive set of recommendations for disaster practitioners, which will form one of the core elements of the CARISMAND Work Package 9 ‘Toolkit’. These recommendations, which have all been formulated on the basis of Work Packages 2-10 results, were structured in four, main “sets”: 1. Approaches to ethnicity in disaster management; 2. Culturally aware disaster-related training activities; 3. Cultural factors in disaster communication, with the sub-sets: a. Cultural values and emotions; (cross-)cultural symbols; “physical” aides and methods; b. Involvement of cultural leaders; involvement of specific groups; usage of social media and mobile phone apps; and 4. Improving trust, improving disaster management. In an initial general assembly, the event started with presentations of the CARISMAND project and its main goals and concepts, including the concept of culture adopted by CARISMAND, and the planned CARISMAND Toolkit architecture and functionalities. These were followed by a detailed presentation of the first of the above mentioned sets of recommendations for practitioners. Then, participants of the Stakeholder Assembly were split into small groups in separate breakout rooms, where they discussed and provided feedback to the presented recommendations. Over the course of the 2-day event, this procedure was followed for all four sets of recommendations. To follow the cyclical design of CARISMAND events, and wherever meaningful and possible, the respective Toolkit recommendations for practitioners provided also the basis for a respective “shadow” recommendation for citizens which will be discussed accordingly in the last round of CARISMAND Citizen Summits (Citizen Summit 5 in Lisbon, and Citizen Summit 6 in Utrecht) in 2018. The location of the Third Stakeholder Assembly was selected to make use of the extensive local professional network of the Civil Protection Department in Lisbon, but also due to Portugal being a traditional “melting pot” where, over more than a millennium, people from different cultural backgrounds and local/ethnical origins (in particular Africa, South America, and Europe) have lived both alongside and together. All documents related to the Working Groups, i.e. discussion guidelines and consent forms, were translated into Portuguese. Accordingly, all presentations, as well as the group discussions were held in Portuguese, aiming to avoid any language/education-related access restrictions, and allowing participating practitioners to respond intuitively and discuss freely in their native language. For this purpose, simultaneous interpreters and professional local moderators were contracted via a local market research agency (EquaçãoLógica), which also provided the basic data analysis of all Working Group discussions and an independent qualitative evaluation of all recommendations presented in the event. The results of this analysis and evaluation will demonstrate that most recommendations were seen by the participating practitioners to be relevant and useful. In particular, those recommendations related to the use of cultural symbols and the potential of mobile phone apps and/or social media were perceived as stimulating and thought-provoking. Some recommendations were felt to be less relevant in the specific Portuguese context, but accepted as useful in other locations; a very small number was perceived to be better addressed to policy makers rather than practitioners. These and all other suggestions for improvement of the presented CARISMAND Toolkit recommendations for practitioners have been taken up and will be outlined in the final chapter of this report.The project was co-funded by the European Commission within the Horizon2020 Programme (2014-2020).peer-reviewe

Rethinking Research Partnerships: Discussion Guide and Toolkit

In recent years, there has been a drive towards research collaboration between academics and international non-governmental organisations (INGOs). These new partnerships offer exciting opportunities to improve learning and practice in international development, leading to innovation and deepened understandings of the world and, ultimately, a better impact on poverty eradication. However, they also present considerable challenges. How do organisations with different structures, goals and interests collaborate? Can they work together productively around these differences? What tensions exist and what is the impact of these? How is power distributed and which voices are amplified or lost in the process? This guide does not seek to answer these questions, but offers a way of exploring them. It is aimed at people and organisations that are considering embarking on a research collaboration, or are already working in partnership. It introduces some of the key issues that arise when working collaboratively, and suggests tools and activities to help you to critically reflect on them. The guide is aimed at those at the forefront of these partnerships – academics, INGO staff and their respective institutions. However, the content will also be of relevance to funders and others seeking to support or encourage collaborative research approaches. This guide is a toolkit for critical reflection, rooted in the idea that research partnerships must be entered into with care. Attention needs to be given to contexts, power relations and the different interests involved in order to successfully deliver truly collaborative knowledge generation that serves everyone’s interests. The risks are real – partnerships without serious considerations of the power dynamics risk reaffirming certain interests and voices and marginalising others, particularly those already experiencing structural disadvantage, undermining the real benefit that these partnerships can bring. In addition, they can end up placing unfunded and unsupported burdens on particular individuals or organisations, and reinforce existing structures that constrain the intended learning and growth
