Bokkapitel (refereegranskat)abstract
- Bookkeeping and accounting is a prevalent feature of small organizations, which has changed face quite substantially with the advent of personal computers and, later, the Internet. The emergence of digitalized accounting procedures has taken place in a nexus of different types of actors (e.g., software developers, accountancy firms and the businesses themselves), regulatory frameworks (e.g., bookkeeping laws and accounting standards) and technical frameworks (e.g., standards for software interactions with banks and tax authorities). Altogether, this has made the paths taken in this process to be largely national. In general, this process of digitalization is largely undocumented and untheorized in research despite its profound impact on practice. Against this backdrop, this chapter has a descriptive and forward-looking approach, documenting the case of how Swedish bookkeeping practices of small organizations became digitalized, which can work as a reference case for comparisons with other national contexts.

The liberalization of railway passenger transport in Sweden : outstanding regulatory challenges
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The purpose of this paper is to describe Sweden’s recent reforms to open the railway passenger markets to entry, and to addresses four critical issues for the success of the reforms; the allocation of infrastructure capacity, the provision of maintenance and terminal facilities, the access to rolling stock and the provision of information and ticketing to travelers. The analysis shows that the legislation and regulatory tools that are needed to handle these challenges to a large extent remain to be developed.

Learning about flood risk : comparing the Web-based and physical flood-walk learning environment

Tidskriftsartikel (refereegranskat)abstract
- Numerous of sustainable development related challenges are emerging today, e.g. flooding problems. Our group has developed ‘the flood walk’ project since 2010 to convey flood risk knowledge in an authentic context. Considering the limitation of time and space to educate people the flood risk knowledge, we tried to transform the physical flood walk field trip into a Web-based virtual trip. In this study, we aim to examine whether the Web-based flood-walk environment can help participants to achieve the same learning outcome as its authentic counterpart. A total of 65 upper secondary school pupils participated in this study. The results illustrate that a physical experience is irreplaceable, and the importance of providing physical experiences for learners in both formal and informal education needs to be emphasised.

The Use of Case-Based Reasoning in a Human-Robot Dialog System
- 2006
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- As long as there have been computers, one goal has been to be able to communicate with them using natural language. It has turned out to be very hard to implement a dialog system that performs as well as a human being in an unrestricted domain, hence most dialog systems today work in small, restricted domains where the permitted dialog is fully controlled by the system.In this thesis we present two dialog systems for communicating with an autonomous agent:The first system, the WITAS RDE, focuses on constructing a simple and failsafe dialog system including a graphical user interface with multimodality features, a dialog manager, a simulator, and development infrastructures that provides the services that are needed for the development, demonstration, and validation of the dialog system. The system has been tested during an actual flight connected to an unmanned aerial vehicle.The second system, CEDERIC, is a successor of the dialog manager in the WITAS RDE. It is equipped with a built-in machine learning algorithm to be able to learn new phrases and dialogs over time using past experiences, hence the dialog is not necessarily fully controlled by the system. It also includes a discourse model to be able to keep track of the dialog history and topics, to resolve references and maintain subdialogs. CEDERIC has been evaluated through simulation tests and user tests with good results.

Konferensbidrag (refereegranskat)abstract
- There is growing evidence that changes in speech and language may be early markers of dementia, but much of the previous NLP work in this area has been limited by the size of the available datasets. Here, we compare several methods of domain adaptation to augment a small French dataset of picture descriptions (n = 57) with a much larger English dataset (n = 550), for the task of automatically distinguishing participants with dementia from controls. The first challenge is to identify a set of features that transfer across languages; in addition to previously used features based on information units, we introduce a new set of features to model the order in which information units are produced by dementia patients and controls. These concept-based language model features improve classification performance in both English and French separately, and the best result (AUC = 0.89) is achieved using the multilingual training set with a combination of information and language model features.

Understanding Spontaneous Negotiation Dialogue
- 1999
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In this paper we present the task-oriented context representation and the dialogue manager for the {\sc Verbmobil} translation system. We show how to utilize statistical methods, shallow extraction and propositional representation to provide translation relevant information and most of all, to enable the system to automatically create a dialogue script and result summary.

Temporal Analysis of Semantic Verbal Fluency Tasks in Persons with Subjective and Mild Cognitive Impairment.
- 2019

Minneapolis, Minnesota, USA, June 6, 2019 / Kate Niederhoffer, Kristy Hollingshead, Philip Resnik, Rebecca Resnik, Kate Loveys (Editors). - Stroudsburg, PA : Association for Computational Linguistics. - 9781948087957

Konferensbidrag (refereegranskat)abstract
- The Semantic Verbal Fluency (SVF) task is a classical neuropsychological assessment where persons are asked to produce words belonging to a semantic category (e.g., animals) in a given time. This paper introduces a novel method of temporal analysis for SVF tasks utilizing time intervals and applies it to a corpus of elderly Swedish subjects (mild cognitive impairment, subjective cognitive impairment and healthy controls). A general decline in word count and lexical frequency over the course of the task is revealed, as well as an increase in word transition times. Persons with subjective cognitive impairment had a higher word count during the last intervals, but produced words of the same lexical frequencies. Persons with MCI had a steeper decline in both word count and lexical frequencies during the third interval. Additional correlations with neuropsychological scores suggest these findings are linked to a person’s overall vocabulary size and processing speed, respectively. Classification results improved when adding the novel features (AUC = 0.72), supporting their diagnostic value.

Managing Traceability Information Models: Not Such a Simple Task After All?
- 2021

Ingår i: IEEE Software. - 0740-7459 .- 1937-4194. ; 38:5

Tidskriftsartikel (refereegranskat)abstract
- Practitioners are poorly supported by the scientific literature when managing traceability information models (TIMs), which capture the structure and semantics of trace links. In practice, companies manage their TIMs in very different ways, even in cases where companies share many similarities. We present our findings from an in-depth focus group about TIM management with three different systems engineering companies. We find that the concrete needs of the companies as well as challenges such as scale and workflow integration are not considered by existing scientific work. We thus issue a call-to-arms for the requirements engineering and software and systems traceability communities, the two main communities for traceability research, to refocus their work on these practical problems.
