Adaptive Hypermedia

Abstract: Adaptive hypermedia is a relatively new direction of research on the crossroads of hypermedia and user modeling. Adaptive hypermedia systems build a model of the goals, preferences and knowledge of each individual user, and use this model throughout the interaction with the user, in order to adapt to the needs of that user. The goal of this paper is to present the state of the art in adaptive hypermedia at the eve of the year 2000, and to highlight some prospects for the future. This paper attempts to serve both the newcomers and the experts in the area of adaptive hypermedia by building on an earlier comprehensive review (Brusilovsky, 1996; Brusilovsky, 1998).

User Modeling in Human–Computer Interaction

Abstract: A fundamental objective of human–computer interaction research is to make systems more usable, more useful, and to provide users with experiences fitting their specific background knowledge and objectives. The challenge in an information-rich world is not only to make information available to people at any time, at any place, and in any form, but specifically to say the “right” thing at the “right” time in the “right” way. Designers of collaborative human–computer systems face the formidable task of writing software for millions of users (at design time) while making it work as if it were designed for each individual user (only known at use time). User modeling research has attempted to address these issues. In this article, I will first review the objectives, progress, and unfulfilled hopes that have occurred over the last ten years, and illustrate them with some interesting computational environments and their underlying conceptual frameworks. A special emphasis is given to high-functionality applications and the impact of user modeling to make them more usable, useful, and learnable. Finally, an assessment of the current state of the art followed by some future challenges is given.

Generic User Modeling Systems

Abstract: The paper reviews the development of generic user modeling systems over the past twenty years. It describes their purposes, their services within user-adaptive systems, and the different design requirements for research prototypes and commercially deployed servers. It discusses the architectures that have been explored so far, namely shell systems that form part of the application, central server systems that communicate with several applications, and possible future user modeling agents that physically follow the user. Several implemented research prototypes and commercial systems are briefly described.

Soliciting information based on a computer user's context

Abstract: A user search request is received and context information for the user is identified. The user search request and the context information are then combined to generate search criteria corresponding to the user search request, providing for information solicitation based on a computer user's context.

Information Filtering: Overview of Issues, Research and Systems

Abstract: An abundant amount of information is created and delivered over electronic media Users risk becoming overwhelmed by the flow of information, and they lack adequate tools to help them manage the situation Information filtering (IF) is one of the methods that is rapidly evolving to manage large information flows The aim of IF is to expose users to only information that is relevant to them Many IF systems have been developed in recent years for various application domains Some examples of filtering applications are: filters for search results on the internet that are employed in the Internet software, personal e-mail filters based on personal profiles, listservers or newsgroups filters for groups or individuals, browser filters that block non-valuable information, filters designed to give children access them only to suitable pages, filters for e-commerce applications that address products and promotions to potential customers only, and many more The different systems use various methods, concepts, and techniques from diverse research areas like: Information Retrieval, Artificial Intelligence, or Behavioral Science Various systems cover different scope, have divergent functionality, and various platforms There are many systems of widely varying philosophies, but all share the goal of automatically directing the most valuable information to users in accordance with their User Model, and of helping them use their limited reading time most optimally This paper clarifies the difference between IF systems and related systems, such as information retrieval (IR) systems, or Extraction systems The paper defines a framework to classify IF systems according to several parameters, and illustrates the approach with commercial and academic systems The paper describes the underlying concepts of IF systems and the techniques that are used to implement them It discusses methods and measurements that are used for evaluation of IF systems and limitations of the current systems In the conclusion we present research issues in the Information Filtering research arena, such as user modeling, evaluation standardization and integration with digital libraries and Web repositories

Machine Learning for User Modeling

Abstract: At first blush, user modeling appears to be a prime candidate for straightforward application of standard machine learning techniques. Observations of the user's behavior can provide training examples that a machine learning system can use to form a model designed to predict future actions. However, user modeling poses a number of challenges for machine learning that have hindered its application in user modeling, including: the need for large data sets; the need for labeled data; concept drift; and computational complexity. This paper examines each of these issues and reviews approaches to resolving them.

System and method for obtaining user preferences and providing user recommendations for unseen physical and information goods and services

Abstract: A system and method for searching data repositories and for obtaining user preferences and providing user recommendations for unseen physical and information goods and services. The system includes, for example, four levels of filtering: content-based, collaborative, event-based and context-based. Filtering is designed to understand and anticipate a user's physical and information goods and services needs by learning about the user's preferences and the preferences of users similar to the user.

Semantic user interface

Abstract: A system and method that allows a user to use their everyday language or user defined words to operate a computer in a highly efficient way. In short, every word, letter, control character and symbol is potentially actionable. A computer user's productivity is dramatically increased by making available those functions that enable a user to produce most of his work through simple, language-based commands. The present invention provides an intuitive interface, referred to as a semantic user interface (SUI), that enhances the operation of the current standard window-based interface in a manner that is simple, richer and natural. By leveraging all of the richness and power inherent in a user's language, the present invention provides an important tool that allows the personal computer to operate in a manner that is much closer to our natural way of interacting. A user is allowed to enter “commands” in his everyday natural language in order to control the operations of the computer. All commands are language-based and user-defined. These commands can be entered from any context of the user's computer (e.g., any application or operating system workspace). The commands allows a user to launch applications and navigate within applications by using language rather than clicks from a pointing device such as a mouse. It also allows the replacement of keystrokes with stored words or keystrokes. The system also keeps a complete archive record of all the text content the user provides as input, regardless of which application program or operating system window the user is operating in at the time. The combined set of all user defined commands and the memory of all the input text that is stored in the archive constitutes the personality profile and is transportable from one computer to another.

Abstract: The present invention provides a system and method for interactively providing product and related information to a user based upon product identification information, such as a UPC code, and enabling the user to engage in various transactions related to the product. According to one aspect of the present invention, the system informs and educates the user about a particular product or service which the user is interested in and enables the user to efficiently purchase the product or service. The system is also configured to offer personalized transactional benefits to the user based on the amount and/or type of personal information that is provided by the user.

Predictive Statistical Models for User Modeling

Abstract: The limitations of traditional knowledge representation methods for modeling complex human behaviour led to the investigation of statistical models. Predictive statistical models enable the anticipation of certain aspects of human behaviour, such as goals, actions and preferences. In this paper, we motivate the development of these models in the context of the user modeling enterprise. We then review the two main approaches to predictive statistical modeling, content-based and collaborative, and discuss the main techniques used to develop predictive statistical models. We also consider the evaluation requirements of these models in the user modeling context, and propose topics for future research.

Context of Use within usability activities

Abstract: Designing for usability involves establishing user requirements for a new system or product, developing design solutions, prototyping the system and the user interface, and testing it with representative users. However, before any usability design or evaluation activity can begin, it is necessary to understand the Context of Use for the product, i.e. the goals of the user community, and the main user, task and environmental characteristics of the situation in which it will be operated. This paper describes the background to, and importance of, understanding Context of Use, and presents a process for performing a context analysis. The method described is particularly aimed at non-experts in the area of user-centred design and evaluation.

System, method and computer program product for gathering and delivering personalized user information

Abstract: A system, method and computer program product for providing a secure data channel between a user and associates. The method may receive pushed information from an associate, including, e.g., an update to the user profile information, related information, or personalized content for the user. The method can convey to the user, personal information including a selectable union of the user profile information, the related information, and/or the personalized content. The method can further share access to the personal information to a family, where the family can include another user, users, or multiple related users. The pushed information can include textual, digitized audio, digitized video, graphical image, or other data, and can include prescription, automobile service, or purchased product information, or voicemail messages.

Empirical Evaluation of User Models and User-Adapted Systems

Abstract: Empirical evaluations are needed to determine which users are helped or hindered by user-adapted interaction in user modeling systems. A review of past UMUAI articles reveals insufficient empirical evaluations, but an encouraging upward trend. Rules of thumb for experimental design, useful tests for covariates, and common threats to experimental validity are presented. Reporting standards including effect size and power are proposed.

Environment-responsive user interface / entertainment device that simulates personal interaction

Abstract: An interaction simulator, such as a chatterbot, is enabled to simulate an awareness of the user to generate an interaction that is more natural and appropriate than prior art chatterbots. For example, the device may employ machine vision to detect the number of persons present or the activity of the user and respond accordingly by interrupting its output or by inviting a conversation or other interaction when a user approaches. The device may modify its responses according to the user's activity, for example, by playing music when the user falls asleep or requesting an introduction when another user speaks. The device may also respond to unrecognized changes in the situation by inquiring about what is going on to stimulate interaction or generate new responses.

User support apparatus and system using agents

Abstract: A user support system employing agent technology is provided. The entrance server identifies the user command by matching it with a collection of anticipated user commands. An index search is performed to identify the contents of the user command. The identified user command is then used to determine which specialized server should respond to the user command. The specialized server contains a collection of action patterns for an agent to use in responding to a user command. An agent supports a user in searching for information and/or navigating to the desired information through friendly conversation with that user. The entrance server is configured as a portal site and a specialized server is provided for each specialized field.

Universal Access in the Information Society: Methods, Tools, and Interaction Technologies

Abstract: Accessibility and high quality of interaction with products, applications, and services by anyone, anywhere, and at any time are fundamental requirements for universal access in the emerging Information Society. This paper discusses these requirements, and their relation to the concept of automated adaptation of user interfaces. An example application is presented, showing how adaptation can be used to accommodate the requirements of different user categories and contexts of use. This application is then used as a vehicle for discussing a new engineering paradigm appropriate for the development of adaptation-based user interfaces. Finally, the paper investigates issues concerning the interaction technologies required for universal access.

Cheese: tracking mouse movement activity on websites, a tool for user modeling

Abstract: Conventional web interfaces respond to and consider only mouse clicks when defining a user model. We have extended this and take into account all mouse movements on a page as an additional layer of information for inferring user interest. We have developed a straightforward way to record all mouse movements on a page, and conducted a user study to analyze and investigate mouse behavior trends. We found certain mouse behaviors, common across many users, which are useful for content providers in increasing the effectiveness of their interface design.

Abstract: This invention provides a method for a subscriber television system client device to provide a three-dimensional user interface comprising a virtual reality media space. The three-dimensional user interface allows the user to navigate a three dimensional environment, participate in activities, and interact with other users. The three-dimensional user interface enables the user to associate personal characteristics with an avatar which represents the user in the system, such personal characteristics comprising a symbol, a picture, and video.

Modelling both the Context and the User

Abstract: Research into context-aware computing risks losing sight of the user. This paper discusses how different types of information about a user, ranging from information about the current context to information about the user’s long-term properties, can simultaneously be relevant to a given adaptation decision. Pointers are given to two areas of research that can help with the integration of a broader range of information into context-aware systems: research on user-adaptive systems and on decision-theoretic methods.

A Unifying Reference Framework for the Development of Plastic User Interfaces

Abstract: The increasing proliferation of computational devices has introduced the need for applications to run on multiple platforms in different physical environments. Providing a user interface specially crafted for each context of use is extremely costly and may result in inconsistent behavior. User interfaces must now be capable of adapting to multiple sources of variation. This paper presents a unifying framework that structures the development process of plastic user interfaces. A plastic user interface is capable of adapting to variations of the context of use while preserving usability. The reference framework has guided the design of ARTStudio, a model-based tool that supports the plastic development of user interfaces. The framework as well as ARTStudio are illustrated with a common running example: a home heating control system.

Individual recommender database using profiles of others

Abstract: A data-class recommender, such an electronic program guide that recommends television programs, avoids users getting trapped in a rut when the users select the same programming material over and over again. In an embodiment, the recommender may be programmed automatically to leverage the profile of another user to broaden the user's profile. For example, the recommender may use the target descriptions of other users in a same household of the user as a guide for broadening the user's profile. Alternatively, the household profile may be used as a filter for source material for soliciting feedback from the user. In this way, rather than simply broadening the user's range arbitrarily, guidance from other profiles, related in some way to the user, is obtained and leveraged. Note that the “relationship” can include friends, published stereotypes representing interests of the user, and others.

Regulating users of online forums

Abstract: Regulating a user of a computer-based service includes receiving input about a first user from at least one other user of the computer-based service, determining a degree to which the at least one other user can influence a parameter associated with the first user, and modifying the first user's parameter based on the received input and the determined degree of influence. The first user's parameter, for example, can relate to the first user's ability to use the computer-based service.

Customer self service subsystem for adaptive indexing of resource solutions and resource lookup

Abstract: An adaptive resource indexing and lookup method for a customer self service system that performs resource search and selection and includes a resource library having selectable resources. The method includes steps of: receiving a current user query for requesting resources; receiving a user context vector associated with the current user query, the user context vector comprising data associating an interaction state with the user; mapping each user query and associated context vector to a sub-set of resources from the resource library; and, generating a response set including the sub-set of resources that are most relevant to the user's query. An adaptive indexing function implementing a supervised learning algorithm is applied for increasing the value of search results for a current user in their context and for enhancing and optimizing the performance of the resource indexing functions by increasing their relevance and specificity for mapping user queries to resources.

Techniques for identifying and accessing information of interest to a user in a network environment without compromising the user's privacy

Abstract: Techniques for identifying and accessing documents (e.g., web pages) of interest to a user in a network environment without compromising the user's privacy. A user system receives index information comprising information related to documents stored in a network environment. The index information is then used to identify and access documents of interest to the user. The identification of documents of interest to the user is performed on the user system thus obviating the need to provide any information to search engines executing on remote servers. The present invention preserves user privacy by controlling and minimizing the communication and collection of user-related information from the user system. Merely by way of example, the present invention allows users to identify and access web pages from web servers coupled to a communication network such as the Internet without compromising user privacy.

Method and apparatus for setting user communication parameters based on voice identification of users

Abstract: The present invention provides a method and apparatus for setting user communication parameters for a voice communication between a calling party and a called party, whereby at least one of the calling party and the called party include at least a first user and a second user. In the present invention, after a voice communication is established between the parties, a user communication parameter of the first user is set if the first user is determined to be a registered user in accordance with the first user's identification. If the first user passes the communication to the second user, the communication parameter is changed to that of the second user by determining the second user's identification. The present invention also provides a method and apparatus for setting user communication parameters based on priority information of the users if the first and second users are in the communication simultaneously. The priority may be determined by one of order of participation in the communication, pre-assigned priority and amount paid to a service provider. If the priority is the same between users, a secondary determination may be made by another one of order of participation in the communication, pre-assigned priority and amount paid to a service provider.
