This study aims to identify user perception of different qualities of optical character recognition (OCR) in texts. The purpose of this paper is to study the effect of different quality OCR on users' subjective perception through an interactive information retrieval task with a collection of one digitized historical Finnish newspaper.

This study is based on the simulated work task model used in interactive information retrieval. Thirty-two users made searches to an article collection of Finnish newspaper Uusi Suometar 1869–1918 which consists of ca. 1.45 million autosegmented articles. The article search database had two versions of each article with different quality OCR. Each user performed six pre-formulated and six self-formulated short queries and evaluated subjectively the top 10 results using a graded relevance scale of 0–3. Users were not informed about the OCR quality differences of the otherwise identical articles.

The main result of the study is that improved OCR quality affects subjective user perception of historical newspaper articles positively: higher relevance scores are given to better-quality texts.

To the best of the authors’ knowledge, this simulated interactive work task experiment is the first one showing empirically that users' subjective relevance assessments are affected by a change in the quality of an optically read text.

The purpose of this paper is to test the effects of citizens’ support for two rival and opposing conceptions of political involvement, political consumerism and stealth democracy, on their attitudes about demand response (flexible consumption) and prosumerism (self-production) in the context of making of Finnish energy policy. Stealth democracy represents an established view on the role of citizens in energy policy making: the energy sector has traditionally been presented as a technocratic domain reserved for experts and businessmen. By contrast, political consumerism can be seen as an expression of “energy democracy”.

The data is based on a postal survey and an internet survey that were conducted in 2016 among a random sample representing Finns who were between 18 and 75 years. The dependence of the support for demand response and prosumerism on the endorsement of political consumerism and stealth democracy will be tested statistically (Pearson chi-square).

The endorsement of demand response mainly depended statistically on citizens’ attitudes towards political consumerism and stealth democracy. However, comparing electricity prices and changing electricity suppliers did not depend on adherence to political consumerism and stealth democracy. Nevertheless, in these cases, support was higher among the supporters of political consumerism than among supporters of stealth democracy. By contrast, the endorsement of prosumerism, for instance, in terms of factors that influence citizens’ decisions to invest in electricity generation in their households, depended statistically on citizens’ attitudes on political consumerism and stealth democracy.

It might be that the variables used in this study to measure stealth democracy are not specific enough. More generally, Finns’ willingness to support for stealth democracy may be based on or at least encouraged by the misunderstandings of democratic politics: more information is needed on the level of knowledge that citizens have about normative principles of democratic decision-making processes.

The implication of this study for energy policy making is that there are (at least in Finland) good preconditions for developing a decentralized energy system: citizens are ready to adopt a more active role as energy citizens in terms of demand response and prosumerism – irrespective of their attitudes on macro-level attitudes on governmental institutions. Democratization of the energy system could strengthen the legitimacy of energy policy making.

Citizens’ attitudes indicate that their potential for involvement needs to be strengthened in the spirit of energy democracy: the idea of energy democracy needs to be seen in terms of the demand for increased accountability and democratization of the energy sector that was previously not seen as requiring public involvement and was most often depoliticized and dominated by technocrats. However, strengthening energy democracy through demand response and prosumerism is not without its problems: utilization of these devices requires a relatively large amount of resources which depend on the individuals’ socio-economic position. Thus, energy democracy cannot replace but complement electoral participation as a form of energy policy involvement.

The contribution of this study is to fill a part of the research gap linking to ongoing energy transitions. As a socio-technical transition can take place only if citizens support and participate in it, we need to better understand citizens’ attitudes on energy consumption and production and energy policy involvement. Citizens’ attitudes on energy production and consumption are becoming more and more critical for managing the energy sector as a result of that the share of wind power and solar power is increasing in the energy system. In a decentralized energy system, citizens have to be prepared to change their modes of operation. To the best of the authors’ knowledge, the originality of this study is to test the impact of citizens’ political attitudes on the endorsement of demand response and prosumerism.
