This article reports the results of a survey of literature on measures of library effectiveness. This survey led to the formulation of six criterion concepts (accessibility, cost, user satisfaction, response time, cost/benefit ratio, and use). The advantages and disadvantages of each method of measurement are discussed. Several points which became clear during the analysis are discussed. First, there is a relative lack of concern with the rationale behind the evaluation process, although the results invariably lead to a confused interpretation when there is no clear understanding of the purpose of an evaluation. Second, the total library system is rarely considered; instead, each evaluation criterion is taken in isolation rather than as part of the whole. Third, the library's preservation function has not been considered at all. 相似文献

工作满意度是员工对自己工作喜欢或不喜欢的感情和情绪,同时,工作满意度也是生活满意度的一个组成部分。工作满意度的提高会促进生活满意度的提高,反过来,生活满意度的提高也会促进工作满意度的提高。本调查选取编辑为主要调查人群,目的就在于,首先诊断出版企业存在潜在的问题;其次找出现阶段出现的主要问题的原因(例如,确定是否因员工工资过低、管理不善、晋升渠道不畅等问题,而不是靠主观的随意猜测);最后,特别是在出版单位由事业向企业转制的过程中,评估组织变化和出版产业政策对编辑的影响,员工满意度调查能够有效地用来评价组织政策和规划中的各种变化,促进企业与员工之间的沟通和交流。 相似文献

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

This paper discusses the use of systems development research methods in the context of ongoing research that is formulating
a specification for a metadata schema registry. The paper extrapolates from this discussion how such methods can be utilized
in archival systems research and how such an approach differs from commercial systems engineering. In particular, the paper
suggests that adopting a user-centred prototyping approach in a research context allows for exploration of the interplay between
theory and practice, advancing the practice, while also offering new insights into theoretical concepts. It argues that these
research methods are of increasing interest to the archival profession in order to conceptualise and realise the tools necessary
to support recordkeeping and archival processes in digital environments. 相似文献

Automatic detection of source code plagiarism is an important research field for both the commercial software industry and within the research community. Existing methods of plagiarism detection primarily involve exhaustive pairwise document comparison, which does not scale well for large software collections. To achieve scalability, we approach the problem from an information retrieval (IR) perspective. We retrieve a ranked list of candidate documents in response to a pseudo-query representation constructed from each source code document in the collection. The challenge in source code document retrieval is that the standard bag-of-words (BoW) representation model for such documents is likely to result in many false positives being retrieved, because of the use of identical programming language specific constructs and keywords. To address this problem, we make use of an abstract syntax tree (AST) representation of the source code documents. While the IR approach is efficient, it is essentially unsupervised in nature. To further improve its effectiveness, we apply a supervised classifier (pre-trained with features extracted from sample plagiarized source code pairs) on the top ranked retrieved documents. We report experiments on the SOCO-2014 dataset comprising 12K Java source files with almost 1M lines of code. Our experiments confirm that the AST based approach produces significantly better retrieval effectiveness than a standard BoW representation, i.e., the AST based approach is able to identify a higher number of plagiarized source code documents at top ranks in response to a query source code document. The supervised classifier, trained on features extracted from sample plagiarized source code pairs, is shown to effectively filter and thus further improve the ranked list of retrieved candidate plagiarized documents. 相似文献
