- Social media platforms have created new ways for people to communicate and express themselves. Thus, it is important to explore how e-health related information is generated and disseminated in these platforms. The aim of our current efforts is to investigate the content and flow of information when people in Sweden use Twitter to talk about diabetes related issues. To achieve our goals, we have used data mining and visualization techniques in order to explore, analyze and cluster Twitter data we have collected during a period of 10 months. Our initial results indicate that patients use Twitter to share diabetes related information and to communicate about their disease as an alternative way that complements the traditional channels used by health care professionals.

- This article describes our work in developing an application that recognizes automatically generated tweets. The objective of this machine learning application is to increase data accuracy in sociolinguistic studies that utilize Twitter by reducing skewed sampling and inaccuracies in linguistic data. Most previous machine learning attempts to exclude bot material have been language dependent since they make use of monolingual Twitter text in their training phase. In this paper, we present a language independent approach which classifies each single tweet to be either autogenerated (AGT) or human-generated (HGT). We define an AGT as a tweet where all or parts of the natural language content is generated automatically by a bot or other type of program. In other words, while AGT/HGT refer to an individual message, the term bot refers to non-personal and automated accounts that post content to online social networks. Our approach classifies a tweet using only metadata that comes with every tweet, and we utilize those metadata parameters that are both language and country independent. The empirical part shows good success rates. Using a bilingual training set of Finnish and Swedish tweets, we correctly classified about 98.2% of all tweets in a test set using a third language (English).

Sonifying the periphery: Supporting the formation of gestalt in air traffic control

Konferensbidrag (refereegranskat)abstract
- We report a design-led exploration of sonification to provide peripheral awareness in air traffic control centers. Our assumption is that by using musical sounds for sonification of peripheral events, it is possible to create a dynamic soundscape that complements the visual information to support the formation and maintenance of an airspace Gestalt throughout the air traffic controller’s interaction. An interactive sonification concept was designed, focusing on one controlled sector of airspace with inbound and outbound aircraft. A formative assessment of the sonification concept suggests that our approach might facilitate the air traffic controller’s work by providing complementary auditory information about inbound and outbound aircraft, particularly in situations where the traffic volume is moderate to low.

- Our work aims to explore novel approaches to the challenge of designing the interaction between people and automation. Through a case study within the domain of air traffic control, we focus on designing fine-grained human–automation interactions. We design a concept and develop an interactive lo-fi prototype of an assisted sketching system to enable air traffic controllers to interact with automation in a fine-grained manner and to externalize mental images. Assisted sketching seems to offer a possible way to communicate different degrees of predictive certainty using visual cues and interaction. Our insights further suggest that externalization through assisted sketching could encourage exploration of future scenarios, and support communication and collaboration between air traffic controllers and between air traffic controllers and pilots. The explorative benefits for the individual decision-making process might be more evident in situations where air traffic controllers have more time for reflection, for example during planning or debriefing and in educational settings.

Designing for sketching to support concept exploration
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Sketching is a way of exploring early concepts through the act of externalization in a suitable material with the aid of a suitable tool. One could use paper and sketch with a pencil or go digital and sketch with code. What is appropriate to choose depends on the situation and on the skillset of the person who is going to sketch. When sketching is done successfully, the externalization can “speak back” and thus engage the sketcher, and others, in a conversation leading to a better understanding of the sketched concepts as well as new concept ideas. This is thoroughly documented in literature – a typical example would be an architect sketching a site plan on a flat piece of paper and being able to read into the possible movements in the third-dimensional space. Sketching generally works like this in familiar, that is, idiomatic situations for experienced sketchers. In unfamiliar or non-idiomatic situations, existing sketching tools are inadequate for expressing and exploring early concepts. For novice sketchers, with limited sketching literacy, even attempting to sketch in an idiomatic situation can be challenging.Through three cases, I design for concept exploration by enabling sketching to understand how this can be done in new situations. The first case deals with expert sketchers exploring non-idiomatic situations: professional creatives working with fulldome format for visual communication. The second case deals with novice sketchers exploring non-idiomatic situations: design students working with virtual reality. The third case deals with novice sketchers exploring idiomatic situations: air traffic controllers working with finding alternative routes for aircraft in the airspace with automation support.I take a constructive design approach by making design examples and reflecting during and after the process. With the help of the design examples, I engage domain experts through participatory co-design workshops and elicit insights in order to inspire further design work. What I learn through this dynamic making-workshopping-and-reflecting process forms the foundation of the knowledge contribution. It is presented here as three design tactics on how sketching could be like to support concept exploration: 1) be responsive, 2) emulate salient material properties, and 3) be lightweight.

- In recent years, data visualization has become a major area in Digital Humanities research, and the same holds true also in linguistics. The rapidly increasing size of corpora, the emergence of dynamic real-time streams, and the availability of complex and enriched metadata have made it increasingly important to facilitate new and innovative approaches to presenting and exploring primary data. This demonstration showcases the uses of Virtual Reality (VR) in the visualization of geospatial linguistic data using data from the Nordic Tweet Stream (NTS) project (see Laitinen et al 2017). The NTS data for this demonstration comprises a full year of geotagged tweets (12,443,696 tweets from 273,648 user accounts) posted within the Nordic region (Denmark, Finland, Iceland, Norway, and Sweden). The dataset includes over 50 metadata parameters in addition to the tweets themselves.We demonstrate the potential of using VR to efficiently find meaningful patterns in vast streams of data. The VR environment allows an easy overview of any of the features (textual or metadata) in a text corpus. Our focus will be on the language identification data, which provides a previously unexplored perspective into the use of English and other non-indigenous languages in the Nordic countries alongside the native languages of the region.Our VR prototype utilizes the HTC Vive headset for a room-scale VR scenario, and it is being developed using the Unity3D game development engine. Each node in the VR space is displayed as a stacked cuboid, the equivalent of a bar chart in a three-dimensional space, summarizing all tweets at one geographic location for a given point in time (see: https://tinyurl.com/nts-vr). Each stacked cuboid represents information of the three most frequently used languages, appropriately color coded, enabling the user to get an overview of the language distribution at each location. The VR prototype further encourages users to move between different locations and inspect points of interest in more detail (overall location-related information, a detailed list of all languages detected, the most frequently used hashtags). An underlying map outlines country borders and facilitates orientation. In addition to spatial movement through the Nordic areas, the VR system provides an interface to explore the Twitter data based on time (days, weeks, months, or time of predefined special events), which enables users to explore data over time (see: https://tinyurl.com/nts-vr-time).In addition to demonstrating how the VR methods aid data visualization and exploration, we will also briefly discuss the pedagogical implications of using VR to showcase linguistic diversity.

Tidskriftsartikel (refereegranskat)abstract
- We demonstrate an approach that utilizes immersive virtual reality (VR) to explore and interact with corpus linguistics data. Our case study focuses on the language identification parameter in the Nordic Tweet Stream corpus, a dynamic corpus of Twitter data where each tweet originated within the Nordic countries. We demonstrate how VR can provide previously unexplored perspectives into the use of English and other non-indigenous languages in the Nordic countries alongside the native languages of the region and showcase its geospatial variation. We utilize a head-mounted display (HMD) for a room-scale VR scenario that allows 3D interaction by using hand gestures. In addition to spatial movement through the Nordic areas, the interface enables exploration of the Twitter data based on time (days, weeks, months, or time of predefined special events), making it particularly useful for diachronic investigations.In addition to demonstrating how the VR methods aid data visualization and exploration, we briefly discuss the pedagogical implications of using VR to showcase linguistic diversity. Our empirical results detail students’ reactions to working in this environment. The discussion part examines the benefits, prospects and limitations of using VR in visualizing corpus data.

Supporting dispatch decisions for the fire and rescue services
- 2015

Konferensbidrag (refereegranskat)abstract
- Decision support tools for efficient dispatching of fire and rescue resources are developed and evaluated. The tools can give suggestions about which resources to dispatch to new accidents, and help the decision makers in evaluating the current preparedness for handling future accidents. The tools are evaluated using simulation game based experiments, with players from the fire and rescue services. The results indicate that the tools can help the fire and rescue services in identifying the closest resources to new accidents, and to select resources that preserve the preparedness in the area. However, the results also indicate that there is a risk that the tools increase the decision time.

Bilateral Prophylactic Mastectomy in Swedish Women at High Risk of Breast Cancer: A National Survey.
- 2011

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND/OBJECTIVE:: This study attempted a national inventory of all bilateral prophylactic mastectomies performed in Sweden between 1995 and 2005 in high-risk women without a previous breast malignancy. The primary aim was to investigate the breast cancer incidence after surgery. Secondary aims were to describe the preoperative risk assessment, operation techniques, complications, histopathological findings, and regional differences. METHODS:: Geneticists, oncologists and surgeons performing prophylactic breast surgery were asked to identify all women eligible for inclusion in their region. The medical records were reviewed in each region and the data were analyzed centrally. The BOADICEA risk assessment model was used to calculate the number of expected/prevented breast cancers during the follow-up period. RESULTS:: A total of 223 women operated on in 8 hospitals were identified. During a mean follow-up of 6.6 years, no primary breast cancer was observed compared with 12 expected cases. However, 1 woman succumbed 9 years post mastectomy to widespread adenocarcinoma of uncertain origin. Median age at operation was 40 years. A total of 58% were BRCA1/2 mutation carriers. All but 3 women underwent breast reconstruction, 208 with implants and 12 with autologous tissue. Four small, unifocal, invasive cancers and 4 ductal carcinoma in situ were found in the mastectomy specimens. The incidence of nonbreast related complications was low (3%). Implant loss due to infection/necrosis occurred in 21 women (10%) but a majority received a new implant later. In total, 64% of the women underwent at least 1unanticipated secondary operation. CONCLUSIONS:: Bilateral prophylactic mastectomy is safe and efficacious in reducing future breast cancer in asymptomatic women at high risk. Unanticipated reoperations are common. Given the small number of patients centralization seems justified.

Visions of Future News - Consensus or Conflict?
- 2002

-
Konferensbidrag (refereegranskat)abstract
- The move from print to multimedia will cause changes not only to the form of the news service but also the involved processes in the news organizations. The cooperative scenario building technique is used on a number of groups; end-users, management and media professionals to envisioning the news services of the future. We take the perspective of consensus and conflict to illustrate the identified visions. Firstly, we illuminate conflicts and consensus between the groups, regarding their visions and future use scenarios. Secondly, we show the implications of using the cooperative scenariobuilding technique in relation the consensus and conflict perspectives in cooperative design. We conclude that both consensus and conflicts could be found in the scenarios described in the paper and that the cooperative technique was suitable in this context.
