Enabled backchannel: conference Twitter use by digital humanists

Purpose – To date, few studies have been undertaken to make explicit how microblogging technologies are used by and can benefit scholars. This paper aims to investigate the use of Twitter by an academic community in various conference settings, and to pose the following questions: Does the use of a Twitter‐enabled backchannel enhance the conference experience, collaboration and the co‐construction of knowledge? and How is microblogging used within academic conferences, and can one articulate the benefits it may bring to a discipline?Design/methodology/approach – This paper considers the use of Twitter as a digital backchannel by the Digital Humanities (DH) community, taking as its focus postings to Twitter during three different international 2009 conferences. The resulting archive of 4,574 “Tweets” was analysed using various quantitative and qualitative methods, including a qualitative categorisation of Twitter posts by open coded analysis, a quantitative examination of user conventions, and text analysi...

What do people study when they study Twitter? Classifying Twitter related academic papers

Purpose – Since its introduction in 2006, messages posted to the microblogging system Twitter have provided a rich dataset for researchers, leading to the publication of over a thousand academic papers. This paper aims to identify this published work and to classify it in order to understand Twitter based research.Design/methodology/approach – Firstly the papers on Twitter were identified. Secondly, following a review of the literature, a classification of the dimensions of microblogging research was established. Thirdly, papers were qualitatively classified using open coded content analysis, based on the papers title and abstract, in order to analyze method, subject, and approach.Findings – The majority of published work relating to Twitter concentrates on aspects of the messages sent and details of the users. A variety of methodological approaches is used across a range of identified domains.Research limitations/implications – This work reviewed the abstracts of all papers available via database search...

Reinventing Research? Information Practices in the Humanities.

Researchers in the humanities adopt a wide variety of approaches to their research. Their work tends to focus on texts and images, but they use and also create a wide range of information resources, in print, manuscript and digital forms. Like other researchers, they face multiple demands on their time, and so they find the ease and speed of access to digital resources very attractive: some of them note that they are reluctant on occasion to consult texts that require a trip to a distant library or archive. Nevertheless, none of the participants in our study is yet ready to abandon print and manuscript resources in favour of digital ones. Rather, they engage with a range of resources and technologies, moving seamlessly between them. Such behaviours are likely to persist for some time.This is reflected also in how researchers disseminate their research. The overwhelmingly dominant channels are the long-established ones such as journal articles, conferences and workshops, monographs and book chapters. We found only limited use – except among philosophers - of blogs and other social media. We noted the doubts expressed in other fields about quality assurance for users of such media, but also concerns about how best to present material that will be read by non-academic audiences.A key change in humanities research over the past 10-15 years has been the growth of more formal and systematic collaboration between researchers. This is a response in part to new funding opportunities, but also to the possibilities opened up by new technology. Over recent years there has also been a shift from the model under which technology specialists tell researchers how to do their research to more constructive engagement. Like other researchers, scholars in the humanities use what works for them, finding technologies and resources that fit their research, and resisting any pressure to use something just because it is new.But there is little evidence as yet of their taking full advantage of the possibilities of more advanced tools for text-mining, grid or cloud computing, or the semantic web; and only limited uptake of even simple, freely-available tools for data management and sharing. Rather, they manage and store information on their desktops and laptops, and share it with others via email. Barriers to the adoption and take up of new technologies and services include lack of awareness and of institutional training and support, but also lack of standardization and inconsistencies in quality and functionality across different resources. These make for delays in research, repetitive searching, and limitations on researchers’ ability to draw connections and relationships between different resources.

Library and information resources and users of digital resources in the humanities

Purpose – The purpose of this article is to discuss the results of the Log Analysis of Internet Resources in the Arts and Humanities (LAIRAH) study. It aims to concentrate upon the use and importance of information resources, physical research centres and digital finding aids in scholarly research. Design/methodology/approach – Results are presented of web server log analysis of portals for humanities scholars: the arts and humanities data service (AHDS) website and Humbul Humanities Hub. These are used to determine which resources were accessed most often, or seldom. Questionnaire data about perceptions of digital resource use were also gathered. Findings – Information resources such as libraries, archives museums and research centres, and the web pages that provide information about them are vital for humanities scholars. The university library website was considered to be the most important resource, even compared to Google. Secondary finding aids and reference resources are considered more important than primary research resources, especially those produced by other scholars, whose output is less trusted than publications produced by commercial organisations, libraries, archives and museums. Practical implications – Digital resources have not replaced physical information resources and the people who staff them, thus both types of information continue to require funding. Scholars trust the judgment of information professionals, who therefore need to be trained to evaluate and recommend specialist digital research resources. Originality/value – LAIRAH was the first research project to use quantitative data to investigate resource use. Findings about the type of resources used are based on evidence rather than opinions alone. This gives a clearer picture of usage that may be used to plan future information services.

The Digital Wunderkammer: Flickr as a Platform for Amateur Cultural and Heritage Content

Many memory institutions are now digitizing their holdings to provide online access. Although recent developments in technology have allowed users to create high quality digital resources outside institutional boundaries, little consideration has been given to the potential contribution that the general public can make to digitizing cultural heritage. This article seeks to scope the growing trend of the creation of digital images of cultural and heritage materials beyond library, art gallery, or museum walls, particularly focusing on the use of the image-hosting site Flickr (www.flickr.com) as a forum for hosting, discussing, and collecting vintage ephemera. This article discusses how Flickr is currently being used and provides empirical data that demonstrates that the most successful examples of this approach can teach best practice to traditional memory institutions in how to make their collections useful, interesting, and used by online communities. The use of a common, centralized access point to image-based heritage allows a central point for discussing and accessing collections. Furthermore, the adoption of Flickr by libraries and archives can extend the use of collections and the interaction that this affords both the institution and the individual.

Opening Access to collections: The making and using of open digitised cultural content

Purpose – The purpose of this paper is to situate the activity of digitisation to increase access to cultural and heritage content alongside the objectives of the Open Access Movement (OAM). It demonstrates that increasingly open licensing of digital cultural heritage content is creating opportunities for researchers in the arts and humanities for both access to and analysis of cultural heritage materials. Design/methodology/approach – The paper is primarily a literature and scoping review of the current digitisation licensing climate, using and embedding examples from ongoing research projects and recent writings on Open Access (OA) and digitisation to highlight both opportunities and barriers to the creation and use of digital heritage content from galleries, libraries, archives and museums (GLAM). Findings – The digital information environment in which digitised content is created and delivered has changed phenomenally, allowing the sharing and reuse of digital data and encouraging new advances in rese...

How Twitter Is Studied in the Medical Professions: A Classification of Twitter Papers Indexed in PubMed

Background Since their inception, Twitter and related microblogging systems have provided a rich source of information for researchers and have attracted interest in their affordances and use. Since 2009 PubMed has included 123 journal articles on medicine and Twitter, but no overview exists as to how the field uses Twitter in research. Objective This paper aims to identify published work relating to Twitter within the fields indexed by PubMed, and then to classify it. This classification will provide a framework in which future researchers will be able to position their work, and to provide an understanding of the current reach of research using Twitter in medical disciplines. Methods Papers on Twitter and related topics were identified and reviewed. The papers were then qualitatively classified based on the paper’s title and abstract to determine their focus. The work that was Twitter focused was studied in detail to determine what data, if any, it was based on, and from this a categorization of the data set size used in the studies was developed. Using open coded content analysis additional important categories were also identified, relating to the primary methodology, domain, and aspect. Results As of 2012, PubMed comprises more than 21 million citations from biomedical literature, and from these a corpus of 134 potentially Twitter related papers were identified, eleven of which were subsequently found not to be relevant. There were no papers prior to 2009 relating to microblogging, a term first used in 2006. Of the remaining 123 papers which mentioned Twitter, thirty were focused on Twitter (the others referring to it tangentially). The early Twitter focused papers introduced the topic and highlighted the potential, not carrying out any form of data analysis. The majority of published papers used analytic techniques to sort through thousands, if not millions, of individual tweets, often depending on automated tools to do so. Our analysis demonstrates that researchers are starting to use knowledge discovery methods and data mining techniques to understand vast quantities of tweets: the study of Twitter is becoming quantitative research. Conclusions This work is to the best of our knowledge the first overview study of medical related research based on Twitter and related microblogging. We have used 5 dimensions to categorize published medical related research on Twitter. This classification provides a framework within which researchers studying development and use of Twitter within medical related research, and those undertaking comparative studies of research, relating to Twitter in the area of medicine and beyond, can position and ground their work.

3D reconstruction for damaged documents: imaging of the great parchment book

Digitization of historical documents is extremely useful as it allows easy access to the documents from remote locations and removes the need for potentially harmful physical handling. Traditional imaging methods are unsuitable for documents with complex geometry as they will produce images containing perspective distortions, and 3D imaging methods previously proposed for document scanning will often suffer from occlusions and/or require manual alignment of individual range scans. We present a lightweight pipeline for imaging and generating 3D reconstructions of severely damaged and distorted documents which exhibit such complex geometry. We demonstrate our pipeline on The Great Parchment Book of The Honourable The Irish Society, a 17th century survey of the Ulster estates managed by the City of London, which was severely damaged by a fire in 1786.

Interactive Exploration and Flattening of Deformed Historical Documents

We present an interactive application for browsing severely damaged documents and other cultural artefacts. Such documents often contain strong geometric distortions such as wrinkling, buckling, and shrinking and cannot be flattened physically due to the high risk of causing further damage. Previous methods for virtual restoration involve globally flattening a 3D reconstruction of the document to produce a static image. We show how this global approach can fail in cases of severe geometric distortion, and instead propose an interactive viewer which allows a user to browse a document while dynamically flattening only the local region under inspection. Our application also records the provenance of the reconstruction by displaying the reconstruction side by side with the original image data.

Documentation and the users of digital resources in the humanities.

Purpose - The purpose of this paper is to discuss the importance of documentation for digital humanities resources. This includes technical documentation of textual markup or database construction, and procedural documentation about resource construction.Design/methodology/approach - A case study is presented of an attempt to reuse electronic text to create a digital library for humanities users, as part of the UCIS project. The results of qualitative research by the LAIRAH study on provision of procedural documentation are discussed, as also is, user perception of the purpose, construction and usability, of resources collected using semi-structured interviews and user workshops.Findings - In the absence of technical documentation, it was impossible to reuse text files with inconsistent markup (COCOA and XML) in a Digital Library. Also, although users require procedural documentation, about the status and completeness of sources, and selection methods, this is often difficult to locate.Practical implications - Creators of digital humanities resources should provide both technical and procedural documentation and make it easy to find, ideally from the project web site. To ensure that documentation is provided, research councils could make documentation a project deliverable. This will be even more vital once the AHDS is no longer funded to help ensure good practice in digital resource creation.Originality/value - Previous work has argued that documentation is important. However, the paper presents actual evidence of the problems caused by a lack of documentation and shows that this makes reuse of digital resources almost impossible. This is intended to persuade project creators who wish resources to be reused to provide documentation about its contents and technical specifications.
