Technical term translations are important for cross-lingual information retrieval. In many languages, new technical terms have a common origin rendered with different spelling of the underlying sounds, also known as cross-lingual spelling variants (CLSV). To find the best CLSV in a text database index, we contribute a formulation of the problem in a probabilistic framework, and implement this with an instance of the general edit distance using weighted finite-state transducers. Some training data is required when estimating the costs for the general edit distance. We demonstrate that after some basic training our new multilingual model is robust and requires little or no adaptation for covering additional languages, as the model takes advantage of language independent transliteration patterns. We train the model with medical terms in seven languages and test it with terms from varied domains in six languages. Two test languages are not in the training data. Against a large text database index, we achieve 64–78 % precision at the point of 100% recall. This is a relative improvement of 22% on the simple edit distance.  相似文献

When searching for health information, results quality can be judged against available scientific evidence: Do search engines return advice consistent with evidence based medicine? We compared the performance of domain-specific health and depression search engines against a general-purpose engine (Google) on both relevance of results and quality of advice. Over 101 queries, to which the term ‘depression’ was added if not already present, Google returned more relevant results than those of the domain-specific engines. However, over the 50 treatment-related queries, Google returned 70 pages recommending for or against a well studied treatment, of which 19 strongly disagreed with the scientific evidence. A domain-specific index of 4 sites selected by domain experts was only wrong in 5 of 50 recommendations. Analysis suggests a tension between relevance and quality. Indexing more pages can give a greater number of relevant results, but selective inclusion can give better quality.  相似文献

This article addresses the notion of ‘making it’ as an early-career academic in physical education and sport pedagogy. In it, we draw on the tradition of material semiotics to reflect on our shared journeys from doctoral student to beginning scholar and beyond. By attuning ourselves to the relationality, materiality and precariousness of our experiences, we offer an answer to the question of what it takes to ‘make it’ as an early-career academic by advocating the practice of ‘making do’ or ‘doctoring.’ We develop this argument, first, by describing the narrative methods we used to conduct our inquiry and by explaining the material-semiotic ideas we used to explore the stories it generated. Then, we tell tales of our transitions from higher degree research student to early-career academic, focusing specifically on our ongoing, collective efforts to make do. In our discussion, we explore these narratives and attend to three features of our actions and activities as early-career academics; namely semiotic relationality, material heterogeneity and the precarious processes of heterogeneous engineering through which we sought to make a career in our field. We conclude by encouraging beginning scholars in physical education and sport pedagogy to become sensitive to these aspects of their own agency, and to experiment, experience and tinker together in ways that are attentive, inventive, caring and persistent.  相似文献

In the decade since the founding of WikiLeaks, no non-leak-related issue has dominated coverage of the organization more than the August 2010 allegations made by two women in Stockholm against WikiLeaks founder Julian Assange. This case has been addressed on the WikiLeaks Twitter feed on a consistent basis over the past 6 years. The tweets from WikiLeaks to millions of followers constitute a form of popular communication where a broad—albeit somewhat prefigured—audience is targeted using an open social media platform. With this audience in mind, I analyze the use of Twitter by WikiLeaks to address the 2010 rape allegations against Assange (and the subsequent follow-on events after those allegations), with a particular focus on two issues: (a) the framing by WikiLeaks of the allegations, Sweden, rape, and feminism; and (b) how the sources (links) used in those tweets to back up claims should be seen as part of the general framing process.  相似文献

This study sought to compare the kinetics and kinematics data in a group of habitual shod runners when running in traditional running shoes and newly designed minimalist shoes with lug platform. This novel footwear design claims to simulate barefoot running and reduce energy loss during impact. We compared footstrike angle (FSA), vertical average (VALR) and instantaneous (VILR) loading rates, energy loss and initial vertical stiffness between two shoe conditions. Runners demonstrated a decreased FSA while running in minimalist shoes with lug platform than traditional shoes (= 0.003; Cohen’s = 0.918). However, we did not observe a landing pattern transition. VALR and VILR between two footwear conditions showed no significant difference (= 0.191–0.258; Cohen’s = 0.304–0.460). Initial vertical stiffness (= 0.032; Cohen’s = 0.671) and energy loss (= 0.044; Cohen’s = 0.578) were greater when running in minimalist shoes with lug platform. The results show that minimalist shoes with lug platform reduce the FSA but may not lead to a landing pattern switch or lower vertical loading rates. Interestingly, the new shoe design leads to a greater energy loss than traditional running shoes, which could be explained by a higher initial vertical stiffness.  相似文献

Parents of children who have participated in a conductive education programme in Sweden were asked questions about their reasons for choosing the programme, the expectations they had of it and how they were fulfilled. The results showed that the parents were satisfied with the development of their child, and wanted to continue to take part in further courses with their child. They appreciated the intensive training and found it motivating and enjoyable for the child. They wanted an intensive training for their child because they believed that active training could help the child to develop. The parents learned more about cerebral palsy at the courses and now understood why and how they could train their child. Most of the parents continued the training at home with the child. They experienced financial difficulties in participating in further courses, and found it difficult to stay away from work and family for a long period of time.  相似文献

The present study explored the method of testing muscle mechanical properties through the linear force–velocity (FV) relationships obtained from loaded vertical jumps. Specifically, we hypothesised that the FV relationship parameters depicting the force, power, and velocity of the tested muscles will differ among individuals of different physical fitness. Strength trained, physically active, and sedentary male participants (N = 10 + 10 + 10; age 20–29 years) were tested on maximum countermovement and squat jumps where manipulation of external loads provided a range of F and V data. The observed FV relationships of the tested leg muscles were approximately linear and mainly strong (median correlation coefficients ranged from 0.77 to 0.92; all p < 0.05), independently of either the tested group or the jump type. The maximum power revealed higher values in the strength trained than in the physically active and sedentary participants. This difference originated from the differences in F-intercepts, rather than from the V-intercepts. We conclude that the observed parameters could be sensitive enough to detect the differences among both the individuals of different physical fitness and various jump types. The present findings support using loaded vertical jumps and, possibly, other maximum performance multi-joint movements for the assessment of mechanical properties of active muscles.  相似文献

Institutions of higher education acknowledge that online learning represents a growing segment of the modern learning environment, and most students have mastered basic computer skills. However, reluctance to engage in online learning remains among both faculty and students. This article presents a case study of three schools of nursing that collaboratively developed and implemented an online undergraduate-nursing course. The article discusses the challenges that were encountered by faculty and students. The faculty used the distance education literature to address these challenges related to technological, institutional, and pedagogical aspects of online learning, as well as the recruitment and retention of online learners. Quantitative and qualitative methods were used to evaluate the effectiveness of the course. The paper concludes with suggestions to overcome the challenges of online learning, such that faculty and students receive the inherent rewards.  相似文献
