A new model for aggregating multiple criteria evaluations for relevance assessment is proposed. An Information Retrieval context is considered, where relevance is modeled as a multidimensional property of documents. The usefulness and effectiveness of such a model are demonstrated by means of a case study on personalized Information Retrieval with multi-criteria relevance. The following criteria are considered to estimate document relevance: aboutness, coverage, appropriateness, and reliability. 相似文献

In this paper we present the relevance ranking algorithm named PolarityRank. This algorithm is inspired in PageRank, the webpage relevance calculus method used by Google, and generalizes it to deal with graphs having not only positive but also negative weighted arcs. Besides the definition of our algorithm, this paper includes the algebraic justification, the convergence demonstration and an empirical study in which PolarityRank is applied to two unrelated tasks where a graph with positive and negative weights can be built: the calculation of word semantic orientation and instance selection from a learning dataset. 相似文献

In a special section of the american Annals of the Deaf, Deaf education and the Deaf community in South Africa are discussed. The special section is organized into 7 segments: a historical overview to establish context, the educational context, educators and learners, postgraduate education and employment, perspectives of Deaf children and their parents, sport and the arts, and spiritual lives and mental health. Throughout the entire section, however, the central focus is on the overall foundation (or lack thereof) of education for Deaf learners in South Africa. 相似文献

This paper examines the validity of the Approaches and Study Skills Inventory for Students—short version (ASSIST; Tait et al. in Improving student learning: Improving students as learners, 1998), to be used with Portuguese undergraduate students. The ASSIST was administrated to 566 students, in order to analyse a Portuguese version of this inventory. Exploratory factor analysis (principal axis factor analysis followed by direct oblimin rotation) reproduced the three main factors that correspond to the original dimensions of the inventory (deep, surface apathetic and strategic approaches to learning). The results are consistent with the background theory on approaches to learning. Additionally, the reliability analysis revealed acceptable internal consistency indexes for the main scales and subscales. This inventory might represent a valuable research tool for the assessment of approaches to learning among Portuguese higher education students. 相似文献

Any implementation of an inclusive policy is largely dependent on educators’ attitudes. In Turkey, many teachers who educate preschool children with Special Educational Needs (SEN), and who have not received in‐service teacher training (INSET) are observed to have negative attitudes towards their SEN students. The aim of this article is to examine differences between the attitudes of preschool teachers before and after an INSET course. Sixty‐six preschool teachers were selected for this study which had a single group pre–post‐test design. The teachers’ opinions and attitudes relating to mainstreaming SEN students in regular educational environments were assessed using the ‘Opinions Relative to Mainstreaming’ scale. The data indicate that these teachers were affected by the INSET programme in such a way that their attitudes towards the inclusion of SEN students became more positive. 相似文献

This study examined underground iron ore miners' occupational narratives to uncover how their stories socialize miners into blue-collar careers and reinforce their work identities. Through the root theme of sisu (Finnish for inner determination), underground miners create a status hierarchy that is used to construct a sense of pride around their work and to establish milestones of success for themselves and others in their workgroup. Furthermore, they communicatively construct exemplars that guide their performance and decisions during the unfolding of their work experiences. Their discourses provide alternatives to white-collar conceptualizations and practices of careers and success. 相似文献
