Coherence, engagement, and usefulness as sensemaking criteria in participatory media practice
When skilled practitioners create media artifacts such as web pages, newspaper articles, videos, or business presentations, they are engaging in a pursuit which has consequences for the people who will interact with those artifacts. The juncture of practice, artifact, and consequences involves diverse normative considerations. We have summarized these into three criteria: coherence, engagement, and usefulness. In this paper we report on initial progress to develop a method for assessing these criteria in a particular form of skilled real-time media practice
Sensemaking of real estate management using real options and scenario planning
Healthcare across the world is facing many uncertainties. In Dutch
healthcare, a recent policy change forces health organisations to deal
more efficiently with real estate which makes flexibility more necessary.
In order to support real estate managers in decision making in flexibility,
we developed a method combining scenario planning and real options.
This method is aimed to enhance sensemaking on both the consequences
of future uncertainties on the organisation which influences real estate
management, and on the types of flexibility needed to enable adapting to
these changes. In this way, better real estate strategies can be developed.
Through testing the method in one pilot case, this study shows
sensemaking had taken place. Based on these results, propositions are
developed focusing on the relation between real options, backcasting
scenario planning and sensemaking
Discovery-led refinement in e-discovery investigations: sensemaking, cognitive ergonomics and system design.
Given the very large numbers of documents involved in e-discovery investigations, lawyers face a considerable challenge of collaborative sensemaking. We report findings from three workplace studies which looked at different aspects of how this challenge was met. From a sociotechnical perspective, the studies aimed to understand how investigators collectively and individually worked with information to support sensemaking and decision making. Here, we focus on discovery-led refinement; specifically, how engaging with the materials of the investigations led to discoveries that supported refinement of the problems and new strategies for addressing them. These refinements were essential for tractability. We begin with observations which show how new lines of enquiry were recursively embedded. We then analyse the conceptual structure of a line of enquiry and consider how reflecting this in e-discovery support systems might support scalability and group collaboration. We then focus on the individual activity of manual document review where refinement corresponded with the inductive identification of classes of irrelevant and relevant documents within a collection. Our observations point to the effects of priming on dealing with these efficiently and to issues of cognitive ergonomics at the human–computer interface. We use these observations to introduce visualisations that might enable reviewers to deal with such refinements more efficiently
Exploring the importance of reflection in the control room
While currently difficult to measure or explicitly design for, evidence suggests that providing people
with opportunities to reflect on experience must be recognized and valued during safety-critical
work. We provide an insight into reflection as a mechanism that can help to maintain both individual
and team goals. In the control room, reflection can be task-based, critical for the 'smooth' day-to-day
operational performance of a socio-technical system, or can foster learning and organisational change
by enabling new understandings gained from experience. In this position paper we argue that
technology should be designed to support the reflective capacity of people. There are many
interaction designs and artefacts that aim to support problem-solving, but very few that support
self-reflection and group reflection. Traditional paradigms for safety-critical systems have focussed
on ensuring the functional correctness of designs, minimising the time to complete tasks, etc. Work
in the area of user experience design may be of increasing relevance when generating artefacts that
aim to encourage reflection
You can't always sketch what you want: Understanding Sensemaking in Visual Query Systems
Visual query systems (VQSs) empower users to interactively search for line
charts with desired visual patterns, typically specified using intuitive
sketch-based interfaces. Despite decades of past work on VQSs, these efforts
have not translated to adoption in practice, possibly because VQSs are largely
evaluated in unrealistic lab-based settings. To remedy this gap in adoption, we
collaborated with experts from three diverse domains---astronomy, genetics, and
material science---via a year-long user-centered design process to develop a
VQS that supports their workflow and analytical needs, and evaluate how VQSs
can be used in practice. Our study results reveal that ad-hoc sketch-only
querying is not as commonly used as prior work suggests, since analysts are
often unable to precisely express their patterns of interest. In addition, we
characterize three essential sensemaking processes supported by our enhanced
VQS. We discover that participants employ all three processes, but in different
proportions, depending on the analytical needs in each domain. Our findings
suggest that all three sensemaking processes must be integrated in order to
make future VQSs useful for a wide range of analytical inquiries.Comment: Accepted for presentation at IEEE VAST 2019, to be held October 20-25

Life editing: Third-party perspectives on lifelog content
Lifelog collections digitally capture and preserve personal experiences and can be mined to reveal insights and understandings of individual significance. These rich data sources also offer opportunities for learning and discovery by motivated third parties. We employ a custom-designed storytelling application in constructing meaningful lifelog summaries from third-party perspectives. This storytelling initiative was implemented as a core component in a university media-editing course. We present promising
results from a preliminary study conducted to evaluate the
utility and potential of our approach in creatively
interpreting a unique experiential dataset
TopicViz: Semantic Navigation of Document Collections
When people explore and manage information, they think in terms of topics and
themes. However, the software that supports information exploration sees text
at only the surface level. In this paper we show how topic modeling -- a
technique for identifying latent themes across large collections of documents
-- can support semantic exploration. We present TopicViz, an interactive
environment for information exploration. TopicViz combines traditional search
and citation-graph functionality with a range of novel interactive
visualizations, centered around a force-directed layout that links documents to
the latent themes discovered by the topic model. We describe several use
scenarios in which TopicViz supports rapid sensemaking on large document
collections
Exploring scholarly data with Rexplore.
Despite the large number and variety of tools and services available today for exploring scholarly data, current support is still very limited in the context of sensemaking tasks, which go beyond standard search and ranking of authors and publications, and focus instead on i) understanding the dynamics of research areas, ii) relating authors ‘semantically’ (e.g., in terms of common interests or shared academic trajectories), or iii) performing fine-grained academic expert search along multiple dimensions. To address this gap we have developed a novel tool, Rexplore, which integrates statistical analysis, semantic technologies, and visual analytics to provide effective support for exploring and making sense of scholarly data. Here, we describe the main innovative elements of the tool and we present the results from a task-centric empirical evaluation, which shows that Rexplore is highly effective at providing support for the aforementioned sensemaking tasks. In addition, these results are robust both with respect to the background of the users (i.e., expert analysts vs. ‘ordinary’ users) and also with respect to whether the tasks are selected by the evaluators or proposed by the users themselves
