Curation, curation, curation

The media curation craze has spawned a multitude of new sites that help users to collect and share web content. Some market themselves as spaces to explore a common interest through different types of related media. Others are promoted as a means for creating and sharing stories, or producing personalized newspapers. Still others target the education market, claiming that curation can be a powerful learning tool for web-based content. But who really benefits from the curation task: the content curator or the content consumer? This paper will argue that for curation to fully support learning, on either side, then the curation site has to allow the content curator to research and tell stories through their selected content and for the consumer to rewrite the story for themselves. This brings the curation task inline with museum practice, where museum professionals tell stories through careful selection, organization and presentation of objects in an exhibition, backed up by research. This paper introduces the notion of ‘recuration’ to describe a process in which shared content can be used as part of learning

Semi-automated curation of protein subcellular localization: a text mining-based approach to Gene Ontology (GO) Cellular Component curation

Background: Manual curation of experimental data from the biomedical literature is an expensive and time-consuming endeavor. Nevertheless, most biological knowledge bases still rely heavily on manual curation for data extraction and entry. Text mining software that can semi- or fully automate information retrieval from the literature would thus provide a significant boost to manual curation efforts. Results: We employ the Textpresso category-based information retrieval and extraction system http://www.textpresso.org webcite, developed by WormBase to explore how Textpresso might improve the efficiency with which we manually curate C. elegans proteins to the Gene Ontology's Cellular Component Ontology. Using a training set of sentences that describe results of localization experiments in the published literature, we generated three new curation task-specific categories (Cellular Components, Assay Terms, and Verbs) containing words and phrases associated with reports of experimentally determined subcellular localization. We compared the results of manual curation to that of Textpresso queries that searched the full text of articles for sentences containing terms from each of the three new categories plus the name of a previously uncurated C. elegans protein, and found that Textpresso searches identified curatable papers with recall and precision rates of 79.1% and 61.8%, respectively (F-score of 69.5%), when compared to manual curation. Within those documents, Textpresso identified relevant sentences with recall and precision rates of 30.3% and 80.1% (F-score of 44.0%). From returned sentences, curators were able to make 66.2% of all possible experimentally supported GO Cellular Component annotations with 97.3% precision (F-score of 78.8%). Measuring the relative efficiencies of Textpresso-based versus manual curation we find that Textpresso has the potential to increase curation efficiency by at least 8-fold, and perhaps as much as 15-fold, given differences in individual curatorial speed. Conclusion: Textpresso is an effective tool for improving the efficiency of manual, experimentally based curation. Incorporating a Textpresso-based Cellular Component curation pipeline at WormBase has allowed us to transition from strictly manual curation of this data type to a more efficient pipeline of computer-assisted validation. Continued development of curation task-specific Textpresso categories will provide an invaluable resource for genomics databases that rely heavily on manual curation

Digital Curation at Work: Modeling Workflows for Digital Archival Materials

This paper describes and compares digital curation workflows from 12 cultural heritage institutions that vary in size, nature of digital collections, available resources, and level of development of digital curation activities. While the research and practice of digital curation continues to mature in the cultural heritage sector, relatively little empirical, comparative research on digital curation activities has been conducted to date. The present research aims to advance knowledge about digital curation as it is currently practiced in the field, principally by modeling digital curation workflows from different institutional contexts. This greater understanding can contribute to the advancement of digital curation software, practices, and technical skills. In particular, the project focuses on the role of open-source software systems, as these systems already have strong support in the cultural heritage sector and can readily be further developed through these existing communities. This research has surfaced similarities and differences in digital curation activities, as well as broader sociotechnical factors impacting digital curation work, including the degree of formalization of digital curation activities, the nature of collections being acquired, and the level of institutional support for various software environments

Curating Campus Speakers

Curation—the picking and choosing of materials for pedagogical reasons—regularly occurs on college campuses both inside and outside of the classroom. This brief essay explains that curation in two contexts. Part I discusses the curation of courses inside the classroom. Part II discusses the curation of campus speakers outside the classroom. Though applied to different topics, the process of curation is similar in both contexts. Considering both forms of curation can help illuminate and resolve some of the most important issues underlying the debate regarding controversial campus speakers

Applicability and Utility of the Astromaterials X-Ray Computed Tomography Laboratory at Johnson Space Center

The Astromaterials Acquisition and Curation Office at NASAs Johnson Space Center is responsible for curating all of NASAs astromaterial sample collections (i.e. Apollo samples, Luna Samples, Antarctic Meteorites, Cosmic Dust Particles, Microparticle Impact Collection, Genesis solar wind atoms, Stardust comet Wild-2 particles, Stardust interstellar particles, and Hayabusa asteroid Itokawa particles) [1-3]. To assist in sample curation and distribution, JSC Curation has recently installed an X-ray computed tomography (XCT) scanner to visualize and characterize samples in 3D. [3] describes the instrumental set-up and the utility of XCT to astromaterials curation. Here we describe some of the current and future projects and illustrate the usefulness of XCT in studying astromaterials

A Puff of Steem: Security Analysis of Decentralized Content Curation

Decentralized content curation is the process through which uploaded posts are ranked and filtered based exclusively on users\u27 feedback. Platforms such as the blockchain-based Steemit employ this type of curation while providing monetary incentives to promote the visibility of high quality posts according to the perception of the participants. Despite the wide adoption of the platform very little is known regarding its performance and resilience characteristics. In this work, we provide a formal model for decentralized content curation that identifies salient complexity and game-theoretic measures of performance and resilience to selfish participants. Armed with our model, we provide a first analysis of Steemit identifying the conditions under which the system can be expected to correctly converge to curation while we demonstrate its susceptibility to selfish participant behaviour. We validate our theoretical results with system simulations in various scenarios

Exploring a curatorial turn in journalism

Curation has moved from the ‘rarefied’ atmosphere of museums and exhibitions into journalism where new discourses and practices are proliferating. The changes have attracted academic attention such that journalism is now facing its own curatorial turn akin to what Paul O’Neill identified in museum studies. This article draws on a meta-analysis of journal articles in the field to argue that the prevalent instrumentalist definitions of curation are necessary but not sufficient to capture what the shifts in discourse and practices mean for journalism. In order to derive a more nuanced conceptualization of curation that includes the instrumental and metaphorical, the article draws on literature beyond the field of journalism studies to trace the changing meanings of the term from curation from antiquity to the digital age. The conditions are propitious for the movement of new practices into newsrooms but where it fits in relation to existing professions is intellectually unclear because of a lack of conceptual clarity as to how curation overlaps and differs from other roles. The article offers a preliminary attempt to address this
