Museums have a remit to inspire visitors. However, inspiration is a complex, subjective construct and analyses of inspiration are often laborious. Increased use of social media by museums and visitors may provide new opportunities to collect evidence of inspiration more efficiently. This research investigates the feasibility of a system based on knowledge patterns from FrameNet -a lexicon structured around models of typical experiences -to extract expressions of inspiration from social media.The study balanced interpretation of inspiration by museum staff and computational processing of Twitter data. This balance was achieved by using prototype tools to change a museum's Information Systems in ways that both enabled the potential of new, social-media-based information sources to be assessed, and which caused the museum staff to reflect upon the nature of inspiration and its role in the relationships between the museum and its visitors.The prototype tools collected and helped analyse Twitter data related to two events. Working with museum experts, the value of finding expressions of inspiration in Tweets was explored and an evaluation using annotated content achieved an F-measure of 0.46, indicating that social media may have some potential as a source of valuable information for museums, though this depends heavily upon how annotation exercises are conducted. These findings are discussed along with the wider implications of the role of social media in museums.
Proposing a step-change in preservation system architectures
Structured AbstractPurpose To consider how Digital Preservation system architectures will support Business Analysis of large-scale collections of preserved resources, and the use of Big Data analyses by future researchers.
Design / methodology / approachArchitectural reviews of existing systems. Experimental surveys of large digital collections using existing Digital Preservation tools at Big Data scales. Design of a proposed new architecture to work with Big Data volumes of preserved digital resources -also based upon experience of managing a collection of 30 million digital images.
FindingsModern visualisation tools enable Business Analyses based on file-related metadata, but most currentlyavailable systems need more of this functionality 'out-of-the-box'. Scalability of preservation architecture to Big Data volumes depends upon the ability to run preservation processes in parallel, so indexes that enable effective sub-division of collections are vital. Not all processes scale easily: those that don't require complex management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
