Evaluation of search engines relies on assessments of search results for selected test queries, from which we would ideally like to draw conclusions in terms of relevance of the results for general (e.g., future, unknown) users. In practice however, most evaluation scenarios only allow us to conclusively determine the relevance towards the particular assessor that provided the judgments. A factor that cannot be ignored when extending conclusions made from assessors towards users, is the possible disagreement on relevance, assuming that a single gold truth label does not exist. This paper presents and analyzes the predicted relevance model (PRM), which allows predicting a particular result’s relevance for a random user, based on an observed assessment and knowledge on the average disagreement between assessors. With the PRM, existing evaluation metrics designed to measure binary assessor relevance, can be transformed into more robust and effectively graded measures that evaluate relevance towards a random user. It also leads to a principled way of quantifying multiple graded or categorical relevance levels for use as gains in established graded relevance measures, such as normalized discounted cumulative gain, which nowadays often use heuristic and data-independent gain values. Given a set of test topics with graded relevance judgments, the PRM allows evaluating systems on different scenarios, such as their capability of retrieving top results, or how well they are able to filter out non-relevant ones. Its use in actual evaluation scenarios is illustrated on several information retrieval test collections. 相似文献

The authors outline the Goals, Functions, Roles, and Systems Model (GFRS), a school counseling—specific model for supervising school counselors‐in‐training (SCITs). The GFRS was created as a guide for assisting in supervising and preparing SCITs for the multifaceted tasks they will undertake in their internships and careers. The components of this model are described within the context of the systems influencing supervision of SCITs. The GFRS is detailed to illustrate how it meets the specific needs of school counseling supervision. Examples are included of the GFRS when applied in supervision. 相似文献

This paper discusses an electronic course survey system designed to support evaluation of a modular programme in management taught through distance education. The scale and communication issues raised by distance education, when compounded by a complex rolling modular programme, make conventional evaluation complicated, slow and expensive. To overcome these problems, an automated evaluation process was introduced, partly based on web-based surveying, but significantly emphasising the reporting process and allowing performance indicators and complex analyses to be embedded in high quality word-processed reports, that can be quickly and easily generated after each presentation of a module. The paper discusses the system and the impact that it has had on the evaluation process, before looking to future opportunities for developments in this field, and discussing some of the implications - both expected and unanticipated - that have come out of using automation in the evaluation process. 相似文献

Young Children Understand That Looking Leads to Knowing (So Long as They Are Looking into a Single Barrel) 总被引:5,自引:0,他引:5
3 experiments were conducted to investigate the claim made by Wimmer, Hogrefe, and Perner that 3-4-year-old children do not understand that people gain knowledge about something by looking at it. The first experiment involved a simple forced-choice procedure in which children had to judge which of 2 assistants knew what was inside a box when one of the assistants had looked inside and the other had lifted it up. In this experiment, the children did realize that the assistant who had looked in the box knew its contents. The second experiment followed the Wimmer et al. procedure, but with a simpler question form. The children were just asked to state whether someone knew what was in the box. Again, the children were able to work out that a person who had looked in a box knew what was inside it. In the third experiment, a direct comparison was made between the simpler question and the more complex, double-barreled question asked by Wimmer et al. The children found the more complex question considerably harder. The results of these experiments suggest that, in contrast to the claims made by Wimmer et al., 3- and 4-year-old children do understand that looking leads to knowing, and that their difficulty in the Wimmer et al. study was mainly with the form of the question that they were asked. 相似文献

This article briefly chronicles nearly a decade of research and development activity undertaken in the area of assessment by a group of committed volunteers, ‘The Student Assessment and Classification Working Group’ (SACWG). However, greater attention is given to demonstrating what a self‐help approach can achieve in respect of research and development in higher education, and to identifying the factors that contribute to success in this respect. It is suggested that the approach has transfer value, provided that certain conditions are met. 相似文献
