Task-based evaluation of text summarization using Relevance Prediction   总被引:2,自引:0,他引:2  
This article introduces a new task-based evaluation measure called Relevance Prediction that is a more intuitive measure of an individual’s performance on a real-world task than interannotator agreement. Relevance Prediction parallels what a user does in the real world task of browsing a set of documents using standard search tools, i.e., the user judges relevance based on a short summary and then that same user—not an independent user—decides whether to open (and judge) the corresponding document. This measure is shown to be a more reliable measure of task performance than LDC Agreement, a current gold-standard based measure used in the summarization evaluation community. Our goal is to provide a stable framework within which developers of new automatic measures may make stronger statistical statements about the effectiveness of their measures in predicting summary usefulness. We demonstrate—as a proof-of-concept methodology for automatic metric developers—that a current automatic evaluation measure has a better correlation with Relevance Prediction than with LDC Agreement and that the significance level for detected differences is higher for the former than for the latter.  相似文献

This essay describes a plan for investigating the cultural meanings of hockey in Canada by examining media narratives of high-level amateur and professional hockey during the late nineteenth and early twentieth centuries. In particular, this project analyzes English Canadian newspaper coverage of Stanley Cup games between 1894 and 1907, as well as the telegraph reconstructions that enabled fans to share a simultaneous experience of distant games. Media coverage of hockey brought Canadians into local and national communities of interest, while constructing narratives of manhood, regional rivalry, and civic pride. Hockey played a significant role in the construction of gender and class identities, and in debates about amateurism, professionalism, and community representation in sport. By exploring key issues related to media, gender, and community identities in early hockey, this research addresses important gaps in the study of sport history and the analysis of sport and Canadian popular culture.  相似文献

The present study contributes to the growing body of research on workplace bullying by examining the advice targets receive along with their interpretations of its usefulness. Based on an analysis of interviews with 48 individuals from a variety of occupations, we identified a paradox of workplace bullying advice where targets described themselves as offering the same advice to other targets they had received, even though they believed following the advice either would have made no difference or made their own situations worse. We address the paradox by considering the possibility that urging individual targets to ‘remain calm’ and ‘stay rational’ overestimates the difference a single individual can make, downplays the significance of strong emotional responses to bullying, and constrains the ability to think and act with greater freedom.  相似文献

ABSTRACT

New forms of data like altmetrics are helping librarians to make smarter decisions about their collections. A recent nationwide study administered to librarians at R1 universities shines light on exactly how these metrics are being applied in academia. This article is based on a presentation from the NASIG 31st Annual Conference. It includes survey results addressing previously unknown rates of technology and metrics uptake among collection development librarians, the most popular citation databases and altmetrics services being used to make decisions, and surprising factors that affect attitudes toward the use of metrics.  相似文献

This presentation focused on how elements of the electronic resource lifecycle, such as those described in the NASIG Core Competencies for Electronic Resource Librarians and the Techniques for Electronic Resource Management, apply to the management of physical library projects, including the weeding and shifting of physical collections, a digitization project, as well as other “duties as assigned” that are part of the average librarian’s workload at a small library. Additionally, this presentation touched on issues related to managing print and electronic collections in law libraries.  相似文献

In this article we describe coaching as an intervention for college students with attention deficit/hyperactivity disorder (ADHD). Coaching college students with ADHD empowers individuals to organize and execute their responsibilities, both in academia and in everyday life. With the assistance of a coach, individuals with ADHD can create structure and execute change by identifying strategies that circumvent their deficits in executive functioning. We also present an example of a representative client to illustrate the methods used in coaching. Given the increased risks facing college students with ADHD, coaching is a useful complement to academic advising and intensive therapy. Our discussion includes obstacles to implementing and evaluating an ADHD coaching intervention. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 647–656, 2005.  相似文献
