Abstract
During the workshop, we deeply discussed what CONversational Information ACcess (CONIAC) is and its unique features, proposing a world model abstracting it, and defined the Conversational Agents Framework for Evaluation (CAFE) for the evaluation of CONIAC systems, consisting of six major components: 1) goals of the system’s stakeholders, 2) user tasks to be studied in the evaluation, 3) aspects of the users carrying out the tasks, 4) evaluation criteria to be considered, 5) evaluation methodology to be applied, and 6) measures for the quantitative criteria chosen.

It’s OK to Want to Have a Good Time

Authors: Luke Church and Mariana Marasoiu

Published in: OASIcs, Volume 134, Companion Proceedings of the 9th International Conference on the Art, Science, and Engineering of Programming (Programming 2025)

Abstract
We reflect on our decade or so of experience advising students, corporate teams and policy makers, many of whom really just want to have a good time at work and want others to as well. However, they seem to be embarrassed to say so, they dress their work in the mantle of productivity, and mostly damage it in the process. In this short opinion piece, we argue that it is long past time to say goodnight to Taylorism and ask what models of research aligned to something humane might replace it?

Fast Pseudoalignment Queries on Compressed Colored de Bruijn Graphs

Authors: Alessio Campanelli, Giulio Ermanno Pibiri, and Rob Patro

Published in: LIPIcs, Volume 344, 25th International Conference on Algorithms for Bioinformatics (WABI 2025)

Abstract
Motivation. Indexes for the colored de Bruijn graph (c-dBG) play a crucial role in computational biology by facilitating complex tasks such as read mapping and assembly. These indexes map k-mers (substrings of length k) appearing in a large collection of reference strings to the set of identifiers of the strings where they appear. These sets, colloquially referred to as color sets, tend to occupy large quantities of memory, especially for large pangenomes. Our previous work thus focused on leveraging the repetitiveness of the color sets to improve the space effectiveness of the resulting index. As a matter of fact, repetition-aware indexes can be up to one order of magnitude smaller on large pangenomes compared to indexes that do not exploit such repetitiveness. Such improved space effectiveness, on the other hand, imposes an overhead at query time when performing tasks such as pseudoalignment that require the collection and processing of multiple related color sets. Methods. In this paper, we show how to avoid this overhead. We devise novel query algorithms tailored for the specific repetition-aware representations adopted by the Fulgor index, a state-of-the-art c-dBG index, to significantly improve its pseudoalignment efficiency and without consuming additional space. Results. Our results indicate that with increasing redundancy in the pangenomes, the compression factor provided by the Fulgor index increases, while the relative query time actually reduces. For example, while the space of the Fulgor index improves by 2.5× with repetition-aware compression and its query time improves by 1.6× on a collection of 5,000 Salmonella Enterica genomes, these factors become (6.1×,2.8×) and (11.2×,3.2×) for 50,000 and 150,000 genomes respectively. For an even larger collection of 300,000 genomes, we obtained an index that is 22.3× smaller and 2.2× faster.

Evaluating the Ability of Large Language Models to Reason About Cardinal Directions (Short Paper)

Authors: Anthony G Cohn and Robert E Blackwell

Published in: LIPIcs, Volume 315, 16th International Conference on Spatial Information Theory (COSIT 2024)

Abstract
We investigate the abilities of a representative set of Large language Models (LLMs) to reason about cardinal directions (CDs). To do so, we create two datasets: the first, co-created with ChatGPT, focuses largely on recall of world knowledge about CDs; the second is generated from a set of templates, comprehensively testing an LLM’s ability to determine the correct CD given a particular scenario. The templates allow for a number of degrees of variation such as means of locomotion of the agent involved, and whether set in the first , second or third person. Even with a temperature setting of zero, Our experiments show that although LLMs are able to perform well in the simpler dataset, in the second more complex dataset no LLM is able to reliably determine the correct CD, even with a temperature setting of zero.

Collaboration and learning through live coding (Dagstuhl Seminar 13382)

Authors: Alan Blackwell, Alex McLean, James Noble, and Julian Rohrhuber

Published in: Dagstuhl Reports, Volume 3, Issue 9 (2014)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 13382 "Collaboration and learning through live coding". Live coding is improvised interactive programming, typically to create electronic music and other digital media, done live with an audience. Our seminar was motivated by the phenomenon and experience of live coding. Our conviction was that those represent an important and broad, but seldom articulated, set of opportunities for computer science and the arts and humanities. The seminar participants included a broad range of scholars, researchers, and practitioners spanning fields from music theory to software engineering. We held live coding performances, and facilitated discussions on three main perspectives, the humanities, computing education, and software engineering. The main outcome of our seminar was better understanding of the potential of live coding for informing cross-disciplinary scholarship and practice, connecting the arts, cultural studies, and computing.

Interdisciplinary Design Research for End-User Software Engineering

Authors: Alan Blackwell

Published in: Dagstuhl Seminar Proceedings, Volume 7081, End-User Software Engineering (2007)

Abstract
How does EUSE research build on empirical studies of programmers, and what kinds of empirical research might provide foundations for future EUSE research? My own work on interdisciplinary design draws comparisons across academic and professional boundaries, applying the results to the design of new technologies, and the critical assessment of technology.
