Users are individuals: individualizing user models

by Elaine Rich - International Journal of Man-Machine Studies , 1983
"... It has long been recognized that in order to build a good system in which a person and a machine cooperate to perform a task it is important to take into account some significant characteristics of people. These characteristics are used to build some kind of a "user model". Traditi ..."

". Traditionally, the model that is built is a model of a canonical (or typical) user. But often individual users vary so much that a model of a canonical user is insufficient. Instead, models of individual users are necessary. This article presents some examples of situations in which individual user models

Individual user characteristics and information . . .

by Dereck Toker, Cristina Conati, Ben Steichen, Giuseppe Carenini - CHI 2013 , 2013
"... There is increasing evidence that users’ characteristics such as cognitive abilities and personality have an impact on the effectiveness of information visualization techniques. This paper investigates the relationship between such characteristics and fine-grained user attention patterns. In particu ..."

type. These results are discussed in view of our long-term goal of designing information visualisation systems that can dynamically adapt to individual user characteristics.

Heuristic Evaluation of User Interfaces

by Jukob Nielsen, Rolf Molich - IN: PROCEEDINGS OF THE CHI´90 CONFERENCE, SEATTLE , 1990
"... Heuristic evaluation is an informal method of usability analysis where a number of evaluators are presented with an interface design and asked to comment on it. Four ex-periments showed that individual evaluators were mostly quite bad at doing such heuristic evaluations and that they only found betw ..."

Tailoring the Interface to Individual Users

by Melanie Hartmann, Daniel Schreiber, Max Mühlhäuser , 2008
"... As the input and output capabilities in Ubiquitous Computing are often very limited, the interaction costs are much higher than for traditional desktop applications. Adapting the interface to the user’s needs and preferences is the key to reducing interaction costs and increasing usability of applic ..."

for an individual user in a given situation. We show that it clearly outperforms algorithms that do not consider the user’s situation.

USER ACCEPTANCE OF INFORMATION TECHNOLOGY: TOWARD A UNIFIED VIEW

by Viswanath Venkatesh, Michael G. Morris, Gordon B. Davis, Fred D. Davis , 2003
"... Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formu ..."

Generating Representative Web Workloads for Network and Server Performance Evaluation

by Paul Barford, Mark Crovella , 1997
"... One role for workload generation is as a means for understanding how servers and networks respond to variation in load. This enables management and capacity planning based on current and projected usage. This paper applies a number of observations of Web server usage to create a realistic Web worklo ..."

It also addresses the technical challenges to satisfying this large set of simultaneous constraints on the properties

Private Information Retrieval

by Benny Chor, et al.
"... We describe schemes that enable a user to access k replicated copies of a database ( k * 2) and privately retrieve informationstored in the database. This means that each individual database gets no information on the identity of the item retrieved by the user. For a single database, achieving thi ..."

Using Linear Algebra for Intelligent Information Retrieval

by Michael W. Berry, Susan T. Dumais - SIAM REVIEW , 1995
"... Currently, most approaches to retrieving textual materials from scientific databases depend on a lexical match between words in users' requests and those in or assigned to documents in a database. Because of the tremendous diversity in the words people use to describe the same document, lexical ..."

We call this retrieval method Latent Semantic Indexing (LSI) because the subspace represents important associative relationships between terms and documents that are not evident in individual documents. LSI is a completely

Grouplens: Applying collaborative filtering to usenet news

Furthermore, each user values a different set of messages. Both taste and prior knowledge are major factors in evaluating news

Awareness and Coordination in Shared Workspaces
