Anonymous personalization in collaborative web search 总被引:2,自引:0,他引:2
We present an innovative approach to Web search, called collaborative search, that seeks to cope with the type of vague queries that are commonplace in Web search. We do this by leveraging the search
behaviour of previous searchers to personalize future result-lists according to the implied preferences of a community of
like-minded individuals. This technique is implemented in the I-SPY meta-search engine and we present the results of a live-user
trial which indicates that I-SPY can offer improved search performance when compared to a benchmark search engine, across
a variety of performance metrics. In addition, I-SPY achieves its level of personalization while preserving the anonymity
of individual users, and we argue that this offers unique privacy benefits compared to alternative approaches to personalization. 相似文献

ABSTRACTOpen education resources represent a great opportunity to reduce textbook costs, but many of them have not been evaluated for quality. Librarians and former students in an introduction to engineering course collected and evaluated open education resources to supplement the course textbook in future semesters. Both searching for and evaluating these resources created opportunities for the librarians to evaluate information literacy skills of these students and to provide instruction to improve these skills. 相似文献

The final session of the National Research Center on Learning Disabilities (NRCLD) Responsiveness-to-Intervention (RTI) Symposium, "What are alternative models to LD identification other than RTI?" included four papers that discussed concerns over the exclusive reliance on an RTI approach to learning disability identification, considerations for analyzing proposed LD identification models, and various alternatives to LD identification. The work of the participating panelists is summarized in this discussant paper, and next steps for the NRCLD in light of these presentations are suggested. 相似文献

Employing an experimental design, mother-to-infant transmission of stress was examined. Mothers (N = 117) were randomized to either have a positive or conflictual discussion with their marital partners, after which infants (age = 6 months) participated in a fear and frustration task. Saliva samples were collected to assess maternal cortisol responses to the discussion and infant cortisol responses to the challenge task. Results indicate maternal cortisol reactivity and recovery to the conflict (but not positive) discussion predicted infant cortisol reactivity to the infant challenge. Mothers’ positive affect during the discussion buffered, and intrusion during the free-play potentiated, mother-to-infant adrenocortical transmission. These findings advance our understanding of the social and contextual regulation of adrenocortical activity in early childhood. 相似文献

The purpose of this study was to examine the effects of a federally funded early literacy project that aimed to promote the school readiness skills of preschool-age children from low income families. Through daily, explicit, and systematic instruction, the project targeted to improve preschoolers’ oral language skills, phonological awareness, print awareness, and alphabet knowledge that aligned with the existing curriculum of the local school district. Data were collected through multiple sources at the individual child level, classroom level, and from the family/home environment. Significant gains were found between pre- and post-tests in child outcomes, classroom environments, instructional practices, parent attitudes toward early literacy, and family involvement in literacy activities. Additionally, classroom organization was identified as a significant predictor for children’s receptive language skills. Limitations of the current study and implications for future research as well as instructional practices were discussed. 相似文献

A baseline assessment of the new curriculum standards of mathematics for elementary education in Flanders is presented and discussed. A total of 24 measurement scales, each representing a cluster of standards, covered the whole mathematics curriculum. A total of 5,763 6th-grade students participated in the study. Performance on each scale was summarized by estimating the proportion of students who were nonmasters, intermediate, and good masters. Overall, the more innovative curriculum standards were mastered worse. Few gender differences in performance were observed. 相似文献
