USER’S GUIDE TO VISCOSITY SOLUTIONS OF SECOND ORDER PARTIAL DIFFERENTIAL EQUATIONS
, 1992
"... The notion of viscosity solutions of scalar fully nonlinear partial differential equations of second order provides a framework in which startling comparison and uniqueness theorems, existence theorems, and theorems about continuous dependence may now be proved by very efficient and striking argume ..."

Data Preparation for Mining World Wide Web Browsing Patterns
- KNOWLEDGE AND INFORMATION SYSTEMS
, 1999
"... The World Wide Web (WWW) continues to grow at an astounding rate in both the sheer volume of tra#c and the size and complexity of Web sites. The complexity of tasks such as Web site design, Web server design, and of simply navigating through a Web site have increased along with this growth. An i ..."

server logs. This paper presents several data preparation techniques in order to identify unique users and user sessions. Also, a method to divide user sessions into semantically meaningful transactions is defined and successfully tested against two other methods. Transactions identified
Web Document Clustering: A Feasibility Demonstration
, 1998
"... Abstract Users of Web search engines are often forced to sift through the long ordered list of document “snippets” returned by the engines. The IR community has explored document clustering as an alternative method of organizing retrieval results, but clustering has yet to be deployed on the major s ..."

Unique User-generated Digital Pseudonyms ⋆ Updated: 2007/09/12
"... Abstract. This paper presents a method to generate unique and nevertheless highly random pseudonyms in a distributed environment. More precisely, each user can now generate his pseudonym locally in his personal security environment, e.g. in his smart card or his personal digital assistant. There is ..."

Collusion-Secure Fingerprinting for Digital Data
- IEEE Transactions on Information Theory
, 1996
"... This paper discusses methods for assigning codewords for the purpose of fingerprinting digital data (e.g., software, documents, and images). Fingerprinting consists of uniquely marking and registering each copy of the data. This marking allows a distributor to detect any unauthorized copy and trac ..."

Libckpt: Transparent Checkpointing under Unix
, 1995
"... Checkpointing is a simple technique for rollback recovery: the state of an executing program is periodically saved to a disk file from whichitcan be recovered after a failure. While recent research has developed a collection of powerful techniques for minimizing the overhead of writing checkpoint f ..."

transparent to the programmer, it also supports the incorporation of user directives into the creation of checkpoints. This user-directed checkpointing is an innovation which is unique to our work.
Content-Based Book Recommending Using Learning for Text Categorization
- IN PROCEEDINGS OF THE FIFTH ACM CONFERENCE ON DIGITAL LIBRARIES
, 1999
"... Recommender systems improve access to relevant products and information by making personalized suggestions based on previous examples of a user's likes and dislikes. Most existing recommender systems use collaborative filtering methods that base recommendations on other users' preferences. ..."

. By contrast, content-based methods use information about an item itself to make suggestions. This approach has the advantage of being able to recommend previously unrated items to users with unique interests and to provide explanations for its recommendations. We describe a content-based book recommending
Combining agile methods and user-centered design to create a unique user experience: An empirical inquiry
"... Abstract- With the advent of the Internet and websites, many people believe that website development is as easy as dragging an icon here, placing a menu there, and adding a picture. However, there is more to website design than many people believe especially if you desire to develop a website that m ..."

While there are many software process models and human-computer interaction activities that focus on the user, the integration of these activities is quite difficult, especially as it relates to website development.

Searching The Web: The Public and Their Queries
, 2001
"... In studying actual Web searching by the public at large, we analyzed over one million Web queries by users of the Excite search engine. We found that most people use few search terms, few modified queries, view few Web pages, and rarely use advanced search features. A small number of search terms ar ..."
