Reanimating cultural heritage through digital technologies
Digital technologies are becoming extremely important for web-based cultural heritage applications. This thesis presents novel digital technology solutions to 'access and interact' with digital heritage objects and collections. These innovative solutions utilize service orientation (web services), workflows, and social networking and Web 2.0 mashup technologies to innovate the creation, interpretation and use of collections dispersed in a global museumscape, where community participation is achieved through social networking.
These solutions are embedded in a novel concept called Digital Library Services for Playing with Shared Heritage (DISPLAYS). DISPLAYS is concerned with creating tools and services to implement a digital library system, which allows the heritage community and museum professionals alike to create, interpret and use digital heritage content in visualization and interaction environments using web technologies based on social networking. In particular, this thesis presents a specific implementation of DISPLAYS called the Reanimating Cultural Heritage system, which is modelled on the five main functionalities or services defined in the DISPLAYS architecture, content creation, archival, exposition, presentation and interaction, for handling digital heritage objects.
The main focus of this thesis is the design of the Reanimating Cultural Heritage system's social networking functionality that provides an innovative solution for integrating community access and interaction with the Sierra Leone digital heritage repository composed of collections from the British Museum, Glasgow Museums and Brighton Museum and Art Gallery. The novel use of Web 2.0 mashups in this digital heritage repository also allows the seamless integration of these museum collections to be merged with user or community generated content, while preserving the quality of museum collections data.
Finally, this thesis tests and evaluates the usability of the Reanimating Cultural Heritage social networking system, in particular the suitability of the digital technology solution deployed. Testing is performed with a user group composed of several users, and the results obtained are presented
Representing archaeological uncertainty in cultural informatics
This thesis sets out to explore, describe, quantify, and visualise uncertainty in a
cultural informatics context, with a focus on archaeological reconstructions. For quite
some time, archaeologists and heritage experts have been criticising the often toorealistic
appearance of three-dimensional reconstructions. They have been highlighting
one of the unique features of archaeology: the information we have on our heritage
will always be incomplete. This incompleteness should be reflected in digitised
reconstructions of the past.
This criticism is the driving force behind this thesis. The research examines archaeological
theory and inferential process and provides insight into computer visualisation.
It describes how these two areas, of archaeology and computer graphics,
have formed a useful, but often tumultuous, relationship through the years.
By examining the uncertainty background of disciplines such as GIS, medicine,
and law, the thesis postulates that archaeological visualisation, in order to mature,
must move towards archaeological knowledge visualisation. Three sequential areas
are proposed through this thesis for the initial exploration of archaeological uncertainty:
identification, quantification and modelling. The main contributions of the
thesis lie in those three areas.
Firstly, through the innovative design, distribution, and analysis of a questionnaire,
the thesis identifies the importance of uncertainty in archaeological interpretation
and discovers potential preferences among different evidence types.
Secondly, the thesis uniquely analyses and evaluates, in relation to archaeological
uncertainty, three different belief quantification models. The varying ways that these
mathematical models work, are also evaluated through simulated experiments. Comparison
of results indicates significant convergence between the models.
Thirdly, a novel approach to archaeological uncertainty and evidence conflict visualisation
is presented, influenced by information visualisation schemes. Lastly, suggestions
for future semantic extensions to this research are presented through the
design and development of new plugins to a search engine
