DEI Talks | “Towards AI-Assisted Synthesis of Verified Dafny Methods” by Prof. Cristina Videira Lopes

The talk “Towards AI-Assisted Synthesis of Verified Dafny Methods”, will be presented March the 24th, at 11:00, in room I-105, moderated by Rui Maranhão (DEI).

Abstract:

“LLMs show “great promise” in code synthesis. Can they keep the promise and ensure that the synthesized code is provably correct?
In this talk I will present our work on synthesizing formally verified Dafny methods. LLMs don’t know much about Dafny, but they learn fast with proper RAG-CoT prompts. We spent 6 weeks hand-coding 50 verified algorithms in Dafny, and then GPT4 was able to generate 103 new ones with the right postconditions and the necessary verification hints.
Md Rakib Hossain (Misu) co-led the work, with assistance from Iris Ma. Joint work with James Noble.”

Abstract:

The proliferation of health misinformation, especially during critical times such as pandemics, has underscored the need for effective mechanisms to verify and disseminate accurate health news. This research, guided by Value Sensitive Design (VSD), investigates the integration of Artificial Intelligence (AI) in health fact-checking, aiming to enhance the speed and reliability of information dissemination while ensuring ethical compliance. The study addresses these key research questions: How can AI facilitate the rapid dissemination of authenticated health information? What benefits does AI integration bring to health fact-checking processes? How can AI promote ethically responsible practices in the dissemination of counter-information? Through systematic reviews, case studies, and empirical research, including co-design workshops and surveys, the research evaluates existing AI applications. It develops guidelines for incorporating AI in journalism and public health information systems. This dissertation follows a structured approach centered around the three distinct phases of VSD. During the Conceptual Investigations phase, systematic reviews and meta-analyses were conducted on publications from 2020 to 2022, using the PRISMA process to analyze 57 studies. During the Technical Investigations phase, case studies and semi-structured interviews were conducted with stakeholders. In the Empirical Investigations, technological probes using AI for the dissemination phase of health fact-checking were tested through co-design workshops, focus groups, and surveys. The data collected in the Technical and Empirical phases were analyzed using thematic and exploratory methods. Findings indicate that while AI significantly enhances the efficiency of fact-checking processes, challenges related to equality, governance, and stakeholder trust remain prevalent. The study also explores the socio-technical dynamics of AI applications in fact-checking, emphasizing the importance of value-driven design to mitigate ethical risks and promote inclusivity. The implications of this research are far-reaching, offering guidelines for developing AI-driven tools that are not only technologically effective but also culturally sensitive and ethically sound. By fostering a better understanding of AI’s role in managing health misinformation, this work contributes to the broader discussion on technology governance and the ethical dimensions of digital media in public health contexts.

Abstract:
Shadow libraries are media repositories whose primary goal is to enable access to resources that were previously restricted or inaccessible through other means. These informal publishing streams have the additional capacity to interface knowledge that does not fit or does not aim to fit within formal distribution models.
As a case study, we researched Portuguese-student shadow libraries (PSSLs) as spaces significant beyond their distributive capacity. Through physical, digital and hybrid interfaces, PSSLs challenge contemporary access to published research, enabling community members to produce and distribute informal knowledge and actively questioning the stability of peers’ roles, dependencies, and interdependencies.
This research started by investigating PSSLs community members’ current needs and requirements. Subsequently, we analysed how prominent shadow libraries align with these needs and how available platforms have the necessary affordances to respond to them. Informed by present constraints, we established a set of software requirements to support the creation and transformation of multiple shadow libraries, enable the collection of plural voices and interventions, and ensure these spaces accommodate a diverse range of resources.
In the second moment of our research, we studied shadow libraries from a new lens. We explored potential library discourses using mechanics from pervasive games as a tool with particular traits and potential. In the context of this research, these are particularly relevant due to their capacity to extend experiences beyond fixed timeframes, leading to users’ sustained and continuous involvement; extend the relationship between users and their environment, exploring the boundaries between physical and digital spaces; extend the possible interfaces for interaction introducing new hypotheses for interaction and user engagement; extend the dynamics between users and their community by integrating external variables and reshaping social interactions; extend users’ engagement at a more personal and meaningful level.
Through a practice-based research methodology, we led community members to reconsider shadow library’s distribution and production dynamics, as well as community interactions. Contributions from these explorations establish a holistic set of design strategies that challenge dominant shadow library practices and highlight the importance of protecting projects’ motivations, community requirements, dependencies, and informal principles. Collectively, the strategies and dependencies identified establish a framework for expanding shadow libraries in response to communities’ evolving needs, ultimately shaping access, distribution, production, and publication of knowledge, and peer synergies.

DEI Talks | “AI and the Worlds of Work“ by Prof. Christopher Mathieu (Lund University)

The talk “AI and the Worlds of Work “ will be presented February the 25th, at 11:00, in room I-105, moderated by António Coelho (DEI).

Abstract:

“The effects of AI on work is a central point of discussion and negotiation in many fields. Machines and mechanical tools have replaced some but not all physical manual labour. The assumption is that AI will bring similar changes, eradicating some jobs, transforming many and having little impact on others. At the moment we know very little about which jobs AI will replace, transform, increase or have little real impact on, but we know that the scope of work and jobs is wide, and that changes do not occur automatically, they are usually negotiated, and negotiations have already begun to take place in a number of sectors. While industrial machines largely replaced low-skill, low-paid physically demanding manual work, the assumption is that AI will increasingly have an impact on high-skill, high-qualification, and high-consequence cognitive and even “creative” work. As AI poses challenges to workers of higher standing and better organized, the deployment and use of AI is subject to negotiation and contestation, both at workplaces and in central negotiations between employers and employee representatives. Worlds of work differ from technical and social perspectives, and as we already see, AI is confronted differently dependent upon what types of employees are being impacted and in which jurisdiction. This lecture examines the various reactions to the “threats” and “possibilities” of AI among different types of workers from telecoms to entertainment in Europe and North America, arguing that institutional factors play a significant role in these negotiations and subsequent use and deployment of AI.”

DEI Talks | “Evaluating Diversification in Group Recommendation of Points of Interest” by Prof. Frederico Durão

The talk “Evaluating Diversification in Group Recommendation of Points of Interest” will be presented November 21st, at 15:00, room I-105, moderated by Prof. Rosaldo Rossetti (DEI).

 Abstract:

With the massive availability and use of the Internet, the search for Points of Interest (POI) is becoming an arduous task. POI Recommendation Systems have, therefore, emerged to help users search for and discover relevant POIs based on their preferences and behaviors. These systems combine different information sources and present numerous research challenges and questions. POI recommender systems traditionally focused on providing recommendations to individual users based on their preferences and behaviors. However, there is an increasing need to recommend POIs to groups of users rather than just individuals. People often visit POIs together in groups rather than alone. Thus, some studies indicate that the further users travel, the less relevant the POIs are to them. In addition, the recommendations belong to the same category, without diversity. This work proposes a POI Recommendation System for a group using a diversity algorithm based on members’ preferences and their locations. The evaluation of the proposal involved both online and offline experiments. Accuracy metrics were used in the evaluation, and it was observed that the level at which the results were analyzed was relevant. For the top 3, recommendations without diversity performed better, but diversification positively impacted the results at the top 5 and 10 levels.
