Visualising Museum Stories, Eoin Kilfeather

Publications

Storytelling is fundamental to our ability to understand, and find meaning in, the world around us. Stories allow us to organise and share knowledge, and to identify the relationships between objects, events, and experiences. Within museums stories allow visitors to engage with collections and to gain meaningful understanding of museum objects. Stories transform a collection of objects into a meaningful knowledge structure that connects the objects and give them meaning.

This paper describes the Open Source Storyscope system that has been developed by the EU FP7 DECIPHER project. Storyscope's workspace and tools allow museum professionals and visitors to research, develop, …

Nextgen Flight Deck Data Comm: Auxiliary Synthetic Speech Phase I, Tracy Lennertz, Judith Bürki-Cohen, Andrea L. Sparko, Nickolas D. Macchiarella, Jason Kring, Mike Coman, Tom Haritos, Jeffry Alvarado

Publications

Data Comm—a text-based controller-pilot communication system—is critical to many NextGen improvements. With Data Comm, communication becomes a visual task. Interacting with a visual Data Comm display may yield an unsafe increase in head-down time, particularly for single-pilot operations. This study examined the feasibility of supplementing Data Comm with synthetic speech. To this end, thirty-two pilots flew two experimental scenarios in a Cessna 172 Flight Training Device. In one scenario, ATC communication was with a text-only Data Comm display, in the other, communication was with a text Data Comm display with synthetic speech that read aloud each message (i.e., text+speech). Pilots …

An Infrastructure To Support Data Integration And Curation For Higher Educational Research, Linh B. Ngo, Amy W. Apon, Pengfei Xuan, Kimberley Ferguson, Christin Marshall, John Mccann, Yueli Zheng

Web Supported Emplotment: Using Object And Event Descriptions To Facilitate Storytelling Online And In Galleries, Trevor Collins, Paul Mulholland, Annika Wolff

Publications

The process of emplotment refers to the selection of significant events in a story and the identification of pertinent relations between them, in order to produce a plot providing an interpretation of those events. We are investigating how models of emplotment can be applied to develop web-based tools for creating and interpreting narratives. In particular, we are focusing on the process undertaken by art gallery professionals to design and present exhibitions. This paper presents a set of plot relations developed in collaboration with museum professionals from two national galleries in Ireland, and shows how theories of narrative and digital cultural …

Storyspace: A Story-Driven Approach For Creating Musuem Narratives, Annika Wolff, Paul Mulholland, Tevor Collins

Publications

In a curated exhibition of a museum or art gallery, a selection of heritage objects and associated information is presented to a visitor for the purpose of telling a story about them. The same underlying story can be presented in a number of different ways. This paper describes techniques for creating multiple alternative narrative structures from a single underlying story, by selecting different organising principles for the events and plot structures of the story. These authorial decisions can produce different dramatic effects. Storyspace is a web interface to an ontology for describing curatorial narratives. We describe how the narrative component …

Curate And Storyspace: An Ontology And Web-Based Environment For Describing Curatorial Narratives, Paul Mulholland, Annika Wolff, Trevolr Collins

Publications

focus on describing the heritage objects that the museum holds in its collection. These are used to manage and describe individual heritage objects according to properties such as artist, date and preservation requirements. Curatorial narratives, such as physical or online exhibitions tell a story that spans across heritage objects and have a meaning that does not necessarily reside in the individual heritage objects themselves. Here we present curate, an ontology for describing curatorial narratives. This draws on structuralist accounts that distinguish the narrative from the story and plot, and also a detailed analysis of two museum exhibitions and the curatorial …

An Event-Based Approach To Describing And Understanding Museum Narratives, Paul Mulholland, Annika Wolff, Trevor Collins, Zdenek Zdrahal

Publications

Current museum metadata tends to be focused around the properties of the heritage object such as the artist, style and date of creation. This form of metadata can index a museum’s collection but cannot express the relations between heritage objects and related concepts found in contemporary museum exhibitions. A modern museum exhibition, rather than providing a taxonomic classification of heritage objects, uses them in the construction of curatorial narratives to be interpreted by an audience. In this paper we outline how curatorial narratives can be represented semantically using our Curate Ontology. The Curate Ontology, informed by a detailed analysis of …

Forensic Analysis Of Plug Computers, Scott Conrad, Greg Dorn, Philip Craiger

Publications

A plug computer is essentially a cross between an embedded computer and a traditional computer, and with many of the same capabilities. However, the architecture of a plug computer makes it difficult to apply commonly used digital forensic methods. This paper describes methods for extracting and analyzing digital evidence from plug computers. Two popular plug computer models are examined, the SheevaPlug and the Pogoplug.

Accelerating Image Feature Comparisons Using Cuda On Commodity Hardware, Amy Apon, Seth Warn, Wesley Emeneker, John Gauch, Jackson Cothren

Publications

Given multiple images of the same scene, image registration is the process of determining the correct transformation to bring the images into a common coordinate system—i.e., how the images fit together. Feature based registration applies a transformation function to the input images before performing the correlation step. The result of that transformation, also called feature extraction, is a list of significant points in the images, and the registration process will attempt to correlate these points, rather than directly comparing the input images.

Community Funding Models For Computational Resources, Amy Apon, Jeff Pummill, Dana Brunson
