Semantics of Context-Free Languages
- In Mathematical Systems Theory
, 1968
"... "Meaning " may be assigned to a string in a context-free language by defining "at-tributes " of the symbols in a derivation tree for that string. The attributes can be de-fined by functions associated with each production in the grammar. This paper examines the implications of th ..."

Topic-Sensitive PageRank
, 2002
"... In the original PageRank algorithm for improving the ranking of search-query results, a single PageRank vector is computed, using the link structure of the Web, to capture the relative "importance" of Web pages, independent of any particular search query. To yield more accurate search resu ..."

results, we propose computing a set of PageRank vectors, biased using a set of representative topics, to capture more accurately the notion of importance with respect to a particular topic. By using these (precomputed) biased PageRank vectors to generate query-specific importance scores for pages at query
Mixtures of Probabilistic Principal Component Analysers
, 1998
"... Principal component analysis (PCA) is one of the most popular techniques for processing, compressing and visualising data, although its effectiveness is limited by its global linearity. While nonlinear variants of PCA have been proposed, an alternative paradigm is to capture data complexity by a com ..."

maximum-likelihood framework, based on a specific form of Gaussian latent variable model. This leads to a well-defined mixture model for probabilistic principal component analysers, whose parameters can be determined using an EM algorithm. We discuss the advantages of this model in the context
The Application of Petri Nets to Workflow Management
, 1998
"... Workflow management promises a new solution to an age-old problem: controlling, monitoring, optimizing and supporting business processes. What is new about workflow management is the explicit representation of the business process logic which allows for computerized support. This paper discusses the ..."

the use of Petri nets in the context of workflow management. Petri nets are an established tool for modeling and analyzing processes. On the one hand, Petri nets can be used as a design language for the specification of complex workflows. On the other hand, Petri net theory provides for powerful analysis
Developing a Context-aware Electronic Tourist Guide: Some Issues and Experiences
, 2000
"... In this paper, we describe our experiences of developing and evaluating GUIDE, an intelligent electronic tourist guide. The GUIDE system has been built to overcome many of the limitations of the traditional information and navigation tools available to city visitors. For example, group-based tours a ..."

Following a period of requirements capture, involving experts in the field of tourism, we
MediaBench: A Tool for Evaluating and Synthesizing Multimedia and Communications Systems

The “What” and “Why” of Goal Pursuits: Human Needs and the Self-Determination of Behavior
, 2000
"... Self-determination theory (SDT) maintains that an understanding of human motiva-tion requires a consideration of innate psychological needs for competence, auton-omy, and relatedness. We discuss the SDT concept of needs as it relates to previous need theories, emphasizing that needs specify the nece ..."
