Methods for estimating the number of relevant documents in a collection     

Don Miller  Robert T. Dattola 《Information processing & management》1982,18(4):179-191

Several statistical sampling methods are evaluated for estimating the total number of relevant documents in a collection for a given query. The total number of relevant documents is needed in order to compute recall values for use in evaluating document retrieval systems. The simplest method considered uses simple random sampling to estimate the number of relevant documents. Another type of random sampling, which assigns unequal selection probabilities to the individual documents in the collection, is also investigated. An alternative approach considered uses curve fitting and extrapolation, where a smooth curve is developed which relates precision to document rank. Another curve relates a function of precision to the query-document score. In either case, the curve is extrapolated to the total number of documents in order to estimate the number of relevant documents. Empirical comparisons are made of all three methods.  相似文献

Testing the double-deficit hypothesis in an adult sample     

Miller CJ  Miller SR  Bloom JS  Jones L  Lindstrom W  Craggs J  Garcia-Barrera M  Semrud-Clikeman M  Gilger JW  Hynd GW 《Annals of dyslexia》2006,56(1):83-102

The double-deficit hypothesis of dyslexia posits that reading deficits are more severe in individuals with weaknesses in phonological awareness and rapid naming than in individuals with deficits in only one of these reading composite skills. In this study, the hypothesis was tested in an adult sample as a model of reading achievement. Participants were parents of children referred for evaluation of reading difficulties. Approximately half of all participants reported difficulty learning to read in childhood and a small subset demonstrated ongoing weaknesses in reading. Structural equation modeling results suggest that the double-deficit hypothesis is an accurate model for understanding adult reading achievement. Better reading achievement was associated with better phonological awareness and faster rapid automatized naming in adults. Posthoc analyses indicated that individuals with double deficits had significantly lower reading achievement than individuals with single deficits or no deficits.  相似文献   

Peer‐assisted Student Support at the University of Glamorgan: innovating the learning process?     

Christopher Miller  Gary Packham 《Mentoring & Tutoring: Partnership in Learning》2013,21(1):81-95

This article analyses the overall performance of the Peer‐Assisted Student Support (PASS) Scheme in the Business School at the University of Glamorgan. Observations were made over a seven‐week period to measure the effectiveness of the scheme in terms of enhancing the student learning process. Weekly attendance was measured to establish patterns of demand in terms of age, gender and mentored subject area. Further quantitative and qualitative research was undertaken to provide an insight into the perceived benefits of the scheme in relation to student social development and academic performance. The empirical findings of this article show that PASS attendance is female dominated. Moreover, the research suggests that contrary to previous research, the majority of benefactors reside in the under‐21 age group. The findings also highlight that academic and laboratory‐based subjects are a considerable strain on PASS resources and more significantly superior academic performance is positively correlated with regular PASS attendance.  相似文献   

School‐based Management — pointing directions for twenty‐first century elementary and middle school principals     

R. C. Bradley  William A. Miller 《School Leadership & Management》2013,33(3):347-358

As man rushes to the dawn of the twenty‐first century, his society and our own system of education are engulfed in widespread changes. One of these provocative changes is the new move to the site‐based management concept whereby principals become the chief school officers of their own school site. The school principal, in essence, is to have complete control and responsibility over his/her school — the superintendent does not dictate, but rather, negotiates all school business with his principals. In light of this new movement, these two authors draw a parallel between past and present expectations of building principals and submit a planning model for on‐site managerial administrators to inspect, study and implement in accordance with their own needs. The reader is provided with an array of perspectives with which on‐site administrators must deal if total assumption of school‐site business and school programming becomes a reality in the USA and universally.  相似文献
