- This study seeks to develop a method for identifying the occurrences and proportions of researchers, media and other professionals active in Twitter discussions. As a case example, an anonymised dataset from Twitter vaccine discussions is used. The study proposes a method of using keywords as strings within lists to identify classes from user biographies. This provides a way to apply multiple classification principles to a set of Twitter biographies using semantic rules through the Python programming language.

The Illicit Information Community : Information - Practical Reflections on the Shadow Library AAARG
- 2017

Ingår i: Improving Quality of Life Through Information. - Tampere. - 9789520305246 ; , s. 121-125

Konferensbidrag (refereegranskat)abstract
- This paper presents a netnographic analysis of information needs and practices related to the shadow library AAARG. AAARG is regarded as a portal and community for the sharing and distribution of academic and artistic texts, books and articles. The portal in question is defined as an actor within the guerrilla open access movement, a radical node within the larger open access movement, which is analysed as a cultural field using the theoretical framework of Sociologist Pierre Bourdieu. AAARG is thereafter discussed in an information-practical sense with re- gards to social interaction between individual users’ needs as well as discursive and constructional origins of such needs. These needs and the practices they create are then examined with regards to the order that the platform itself creates, tied to the cultural field which it is a part of. The conclusion is that alternative knowledge organizational platforms such as AAARG have had and will continue to have a big influence on the discussion of today’s open access models, since they clearly fill a certain demand. The discrepancy between such initiatives and institutional open access activities will therefore need further analysis in a library and information scientific context.

Tracing hyperlinks : How to support different forms of presence and knowledge production in an online citizen science community?
- 2021
-
Konferensbidrag (refereegranskat)abstract
- Over the past decade there have been significant improvements in the organizational infrastructures supporting information sharing, retrieval, storage, and use. At present, users with access to online applications can post, read, evaluate, vote for, and elaborate on information sources of all shapes and stripes. In citizen science, this is manifested in projects focusing on volunteer classification of readily available data. While such projects adopt standardized methods for data classification, virtual discussion boards provide possibilities for peers to confer about method uncertainties. In such environments, it is important to explore how emerging organizational forms and sociomaterial dynamics shape a range of knowledge production opportunities. Some might be facilitated by experts providing tutorials which resemble classroom teaching while others emerge out of collective work on discussion boards or agent-centered explorations where participants build hyperlinked resource libraries. Through practices of hyperlinking, digital sources of internal and external information can be drawn into the discussion boards to facilitate debates and conversations, mitigating classification uncertainties. Problematizing standardized methods in relation to peer knowledge from discussion boards, we compare volunteers’ knowledge production practices in a citizen science project on Zooniverse.org. Taking our point of departure in practice theory (Gherardi 2019; Østerlund, Crowston, Jackson 2020), we combine insights from studies of collaborative knowledge production with a sociomaterial informed theory of learning articulated by the STS scholar Sørensen (2009). This is done to unfold how hyperlinking practices expand standardized data classification methods and performatively shape knowledge production in a citizen science project.

Unfolding material constraints and opportunities in biodiversity citizen science information practices

- Introduction. The purpose of this paper is to outline an approach for understanding how information practices in biodiversity citizen science are enabled and constrained through participants’ interactions with material objects such as cameras, artificial intelligence-supported smartphone applications and information systems.Theory. The approach draws on the theory of objectual practice; how knowledge is constructed iteratively through interaction with epistemic objects. Epistemic objects are understood as objects sustained by projections of knowledge, open for interpretation and question-generation, rather than clearly defined things.Empirical context. The approach is empirically contextualised through a study of biodiversity citizen science activities in relation to a bioblitz, a short-term, intensive period of species observations in a given geographical setting. Three empirical units of analysis are to be studied: binoculars, cameras, and loupes for observing species; field guides, identification keys and smartphone applications for identifying species; and standardising, large-scale information systems for reporting identified observations.Concluding discussion The approach opens up for studying how material objects enable and constrain biodiversity citizen science information practices. The objectual practice approach in relation to a multifaceted empirical setting such as biodiversity citizen science extends sociomaterial aspects to citizen science studies by enabling practice-oriented observation and trace investigations of large-scale phenomena.
