在云南方言中,"非"是作为程度副词来使用的,其语义与句法结构形式都跟普通话有较大差异."非"以单音节形式作程度副词使用既不是从古汉语发展而来的,又与现代汉语的用法相差甚远.大理洱海沿岸地区白族话中用[φε44]作程度副词,它是白族话固有的词语,随着民族的融合及文化的交流,[φε44]这一白族话中的程度副词被汉族吸收、借鉴,成为云南方言中特有的表程度的副词. 相似文献

ABSTRACT The increased use of quantitative education data is often regarded by scholars as evidence of the emergence of’governing by numbers’. These scholars ascribe major stakeholders such as the OECD and nation states agency as they produce, distribute and consume data, and respond to these with policy and management initiatives. This paper argues that metrics themselves have a configurative agency that affects education in terms of educational ideas and designs. The paper illustrates this point by analysing two cases of graduate employability metrics, each of which configures education differently, and discusses how the configurative agency of metrics can become the focal point of a different research agenda using distinct analytical concepts drawn from the sociology of quantification and new materialism. The paper concludes that such a research agenda can enable actors involved in the design and development of education to enter into a professional dialogue and engagement with education data, rather than merely dismissing it. 相似文献

Word embeddings, which represent words as numerical vectors in a high-dimensional space, are contextualized by generating a unique vector representation for each sense of a word based on the surrounding words and sentence structure. They are typically generated using such deep learning models as BERT and trained on large amounts of text data and using self-supervised learning techniques. Resulting embeddings are highly effective at capturing the nuances of language, and have been shown to significantly improve the performance of numerous NLP tasks. Word embeddings represent textual records of human thinking, with all the mental relations that we utilize to produce the succession of sentences that make up texts and discourses. Consequently, the distributed representation of words within embeddings ought to capture the reasoning relations that hold texts together. This paper makes its contribution to the field by proposing a benchmark for the assessment of contextualized word embeddings that probes into their capability for true contextualization by inspecting how well they capture resemblance, contrariety, comparability, identity, relations in time and space, causation, analogy, and sense disambiguation. The proposed metrics adopt a triangulation approach, so they use (1) Hume’s reasoning relations, (2) standard analogy, and (3) sense disambiguation. The benchmark has been evaluated against 22 Arabic contextualized embeddings and has proven to be capable of quantifying their differential performance in terms of these reasoning relations. Results of evaluation of the target embeddings revealed that they do take context into account and that they do reasonably well in sense disambiguation but have weakness in their identification of converseness, synonymy, complementarity, and analogy. Results also show that size of an embedding has diminishing returns because the highly frequent language patterns swamp low frequency patterns. Furthermore, the suggest that future research endeavors should not be concerned with the quantity of data as much as its quality, and that it should focus more on the representativeness of data, and on model architecture, design, and training. 相似文献

Abstract Vendor-supplied e-resource statistics are often unavailable, unreliable, or not comparable across vendors. This study compared locally generated usage statistics to those supplied by four major publishers, and analyzed the resulting patterns of use. The additional information provided by vendor statistics was assessed to see how it might be utilized selectively to provide a better understanding of the importance of individual titles. The local statistics for all titles provided by the four publishers were then compared. A strong similarity between the two datasets was found, supporting the position that local statistics are a viable alternative to vendor statistics. Another finding was that the 80/20 rule is closer to 80/30 in the online environment. Some of the issues for subject librarians and electronic resources librarians are discussed. 相似文献
