Towards secure web browsing
… attacks, intensifying the need for secure web browsing systems. Current research efforts to retrofit today's web browsers help to improve security, but fail to address the fundamental design flaws of current browsing systems. To overcome those issues, in this dissertation, we rethink the way we …

Children's Interface Design for Searching and Browsing
… so it is important to design searching and browsing interfaces to support them. However, many interfaces for children do not consider their skills and preferences. Children can perform simple, single item searches, and are also capable of conducting Boolean searches involving multiple search …

Towards integrated document processing and file browsing
By using the World Wide Web (WWW), it has become easy to access information which is distributed over the entire Internet. However, due to the immense and rapidly growing supply of information, the Web Site may contain multiple data types in distinct heterogeneous sources, and stored under …

Hierarchical topic map generation for exploratory browsing
This thesis proposes a novel model for automatically generate topic map for a document corpus with no supervision. We extend a previous approach to discovery of lexical relations from text data to construct a hierarchy of topics. Given a collection of documents, we will generate a set of topics on …

A web browsing workload model for simulation
… model for traffic generated by an individual browsing the web. We derived the workload model by studying packet traces of web traffic generated by individuals browsing the web on a campus network.

Progressive browsing-state delivery for interactive multimedia exploration
Unlike traditional retrieval, dynamic exploration of multimedia collections may require complex aggregation queries whose performance is highly sensitive to dataset size, filters and grouping applied at any time. Such queries often yield unstable response times, thus undermining interactivity. …

Klink Search: Enabling Exploratory Browsing Activities in Digital Libraries
… provide limited support for exploratory browsing activities, which is a crucial step that supports learning during the exploratory search process. The present research addresses this issue by designing and implementing a novel search interface called KLink Search, to support exploratory …

Dynamically exploiting available metadata for browsing and information retrieval
… supporting effective information retrieval and browsing in such repositories. This system is general purpose, involving no hard-coded assumptions about the structure of the repository. An understanding of the end-user's search process is used to provide effective "next steps" to the users …

Response of marula to simulated browsing on a productivity gradient
… factors in regulating savannah functioning are browsing and soil fertility. The aim of this research was to assess the effects of simulated browsing on the physical and chemical properties of marula trees growing on a productivity gradient in a controlled environment. The hypothesis to be tested …

User interface design for keyframe-based content browsing of digital video
… focusing on keyframe-based video content browsing interfaces. By analysing and identifying important elements in designing keyframe-based browsing interfaces, we construct a welldefined "design space" where a specific user interface can be designed by simply selecting a set of available …

Adding, Retrieving and Browsing Content in Social Media and E-Journalism
This thesis explores the use of avatars with facial expressions in social media and e-journalism communication interfaces. This thesis involved three experimental conditions. In the first experimental condition a survey (n=34) and an experiment (n=25) were carried out in order to explore the …

Exploratory and faceted browsing, over heterogeneous and cross-domain data sources
Exploration of heterogeneous data sources increases the value of information by allowing users to answer questions through exploration across multiple sources; users can use information that has been posted across the Web to answer questions and learn about new domains. We have conducted research …

VastMM-Tag: Semantic Indexing and Browsing of Videos for E-Learning
Quickly accessing the contents of a video is challenging for users, particularly for unstructured video, which contains no intentional shot boundaries, no chapters, and no apparent edited format. We approach this problem in the domain of lecture videos though the use of machine learning, to gather …

BlendDB : blending table layouts to support efficient browsing of relational databases
… as is likely to be the case when supporting browsing-oriented applications, performance will be quite poor. This thesis focuses on optimizing the performance of these kinds of path queries in a system called BlendDB, a relational database that supports on-disk co-location of tuples from …
