SUM: an exploration of Shared User Models and Interface Adaptations to Improve Accessibility of Mobile Touchscreen Interactions
… characteristics of an individual’s impairment. User models for personalisation are often constructed from stereotypical generalisations of the similarities of people with disabilities, neglecting to recognise the unique characteristics of the individuals themselves. Existing strategies for …

Adaptive Planning and Prediction in Agent-Supported Distributed Collaboration.
Agents that act as user assistants will become invaluable as the number of information sources continue to proliferate. Such agents can support the work of users by learning to automate time-consuming tasks and filter information to manageable levels. Although considerable advances have been made …

The development and validation of a user's model for interactive text editing
… explore a method of deriving naive and expert user models by use of a clustering algorithm. The models, which consisted of a core set of commands, were developed by applying a hierarchical cluster analysis to the paper and pencil responses of naive and expert subjects. It was expected that in …

The (not so) Intelligent House: User Perception in an Interactive Architectural Environment
… designer-defined disposition, where a user has to adapt to a given setting, to an interactive architecture that adapts to the needs of the user. Yet, built examples show that the reality of intelligent houses is not as open-minded as the theory would have us believe. Often, the …

Intelligent personalized approaches for semantic search and query expansion
… Many services are advertised and provided to the users through online channels. The user looks for services and obtains them through different search engines. To obtain the best results that meet the needs and requirements of the users, researchers have extensively studied methods such as …

A new user model to support electronic commerce
User models incorporate the knowledge about the user so as to increase, in a general sense, the effectiveness of man-machine interaction. Several applications or software agents can use such model-based knowledge to give better and personalized services to end-users. The personalization can be in …

Model-based user interaction for accessing electronic news
… is natural and that does not require elaborate user training. The two main problems in human-computer dialog are resolution of ambiguity and incompleteness. A model-based architecture is introduced in this thesis that provides a solution to these problems. The uniqueness of the solution is based …

Procedurally generated realistic virtual rural worlds
… some tasks and take some of the burden off the user. Input parameters for these procedural algorithms are often unintuitive, however, and their impact on the final results, unclear. This thesis proposes, implements, and evaluates an approach to procedurally generate vegetation and water networks …

Short-term traffic forecasting for a smart satellite communications system
… usage of satellite resources is the change in user terminal traffic during a complete cycle of the system: collecting data, generating a constellation setting solution, transmitting the new solution to each satellite and executing changes to the satellite's parameters. As the system's cycle …

Semantic linking and personalization in context
… Hypermedia (AH) methods using ontology-based user models. In our second contribution, we introduce and implement a novel personalized Semantic Web browser, called SemWeB which is a browser that augments Web documents with metadata. It creates and personalizes context-based hyperlinks and data …

User Simulation in Interactive Information Retrieval : methods and frameworks for simulating complex search behavior
… face challenges in simulating realistic user search behavior. Evolving interaction patterns and the integration of AI-powered interfaces make these challenges even harder. Traditional evaluation methods struggle to capture the dynamic nature of user interactions, particularly in complex …

PerspectiveSpace
… operations are used to perform calculations on user models and microtheories. PerspectiveSpace has applications ranging from discovering subcultures in a larger society to building community-driven web sites that adapt to individual perspectives, and three such applications are illustrated here. …

User interface agents in electronic commerce applications
A User Interface Agent (UIA) is a software entity that assists its users in effectively using the user interface software. In electronic commerce applications, the user interface software plays an important role. Users of different kinds and backgrounds will use this software with different …

Power and delay trade-offs in fading channels
… and power based on the current fading level, a user in a wireless network can more efficiently utilize the available energy. For a given average transmission rate, information theoretic arguments provide the optimal power allocation. However, such an approach can lead to long delays or buffer …

Foundations research in information retrieval inspired by quantum theory
… for dealing with the uncertainty associated with user interactions; so that one has the necessary formal foundation to be able to perceive IR as "search science". The key problems restricting a science of search pertain to the ambiguity in the current way in which search scenarios and concepts are …
