TL;DR: A new scheme to learn dynamic user's interests in an automated information filtering and gathering system running on the Internet that adapts quickly to significant changes in user interest, and is also able to learn exceptions to interest categories.

Abstract: In this paper, we describe a new scheme to learn dynamic user's interests in an automated information filtering and gathering system running on the Internet. Our scheme is aimed to handle multiple domains of long-term and short-term user's interests simultaneously, which is learned through positive and negative user's relevance feedback. We developed a 3-descriptor approach to represent the user's interest categories. Using a learning algorithm derived for this representation, our scheme adapts quickly to significant changes in user interest, and is also able to learn exceptions to interest categories.

Learning in Nonstationary Environments: A Survey
TL;DR: In such nonstationary environments, where the probabilistic properties of the data change over time, a non-adaptive model trained under the false stationarity assumption is bound to become obsolete in time, and perform sub-optimally at best, or fail catastrophically at worst.

TL;DR: In this paper, an improved user interface and method for presenting recommendations to a user when the user adds an item to a shopping cart is presented, where a page generation process generates and returns a page that includes a recommendation portion and a condensed view of the shopping cart.

Personalized web search by mapping user queries to categories
Fang Liu,Clement Yu,Weiyi Meng +2 more
- 04 Nov 2002
TL;DR: A novel technique to map a user query to a set of categories, which represent the user's search intention, is proposed, which can serve as a context to disambiguate the words in the users' query.

Indexing by Latent Semantic Analysis
TL;DR: A new method for automatic indexing and retrieval to take advantage of implicit higher-order structure in the association of terms with documents (“semantic structure”) in order to improve the detection of relevant documents on the basis of terms found in queries.

Learning in the presence of concept drift and hidden contexts
Gerhard Widmer,Miroslav Kubat +1 more
TL;DR: A family of learning algorithms that flexibly react to concept drift and can take advantage of situations where contexts reappear are described, including a heuristic that constantly monitors the system's behavior.
Learning and Revising User Profiles: The Identification ofInteresting Web Sites
TL;DR: The use of a naive Bayesian classifier is described, and it is demonstrated that it can incrementally learn profiles from user feedback on the interestingness of Web sites and may easily be extended to revise user provided profiles.
