Increased computing power and the Web have made information widely accessible. In turn, this has encouraged the development of recommendation systems that help users find items of interest, such as books or restaurants. Such systems are more useful when they personalize themselves to each user's preferences, thus making the recommendation process more(More)
In natural language acquisition, it is difficult to gather the annotated data needed for supervised learning; however, unanno-tated data is fairly plentiful. Active learning methods attempt to select for annotation and training only the most informative examples , and therefore are potentially very useful in natural language applications. However , existing(More)
The authors analyzed data from the 2002 National Study of the Changing Workforce (N = 3,504) to investigate relationships among availability of formal organizational family support (family benefits and alternative schedules), job autonomy, informal organizational support (work-family culture, supervisor support, and coworker support), perceived control, and(More)
This paper focuses on a system, Wolfie (WOrd Learning From Interpreted Examples), that acquires a semantic lexicon from a corpus of sentences paired with semantic representations. The lexicon learned consists of phrases paired with meaning representations. Wolfie is part of an integrated system that learns to transform sentences into representations such as(More)
This paper describes a system, Wolfie (WOrd Learning From Interpreted Examples), that acquires a semantic lexicon from a corpus of sentences paired with semantic representations. The lexicon learned consists of words paired with meaning representations. Wolfie is part of an integrated system that learns to parse novel sentences into semantic(More)
In this paper, we describe the Adaptive Place Advisor, a conversational interface designed to help users decide on a destination. We view the selection of destinations as an interactive process of constraint satisfaction, with the advisory system proposing attributes and the human responding. We further characterize this task in terms of heuristic search,(More)
Background There is no model to estimate absolute invasive breast cancer risk for Hispanic women. Methods The San Francisco Bay Area Breast Cancer Study (SFBCS) provided data on Hispanic breast cancer case patients (533 US-born, 553 foreign-born) and control participants (464 US-born, 947 foreign-born). These data yielded estimates of relative risk (RR)(More)
Breast milk lactose, total nitrogen, conductivity, osmolality, and intake by infants of 33 women with insulin-dependent diabetes mellitus (IDDM), 33 control women without diabetes, and 11 reference women were determined in a 3-mo study of lactation. Milk of women with IDDM had significantly lower lactose and higher total nitrogen (2-3 d postpartum), and(More)
BACKGROUND Prostate ducts and acini whose lumens are filled with malignant cells represent a well-recognized histological pattern recently termed intraductal carcinoma of the prostate (IDC-P). These tumors are often associated with rapid disease progression, and most recur after radical surgery. Controversy exists as to whether IDC-P should be recognized as(More)
