Information plays an increasingly important role in strategic decision-making processes within businesses. Therefore, information quality and its assessment have become critical subjects for information products delivered to information consumers. Commonly, the information product provided to consumers is the output of queries in relational databases. The queries typically consist of one or mor...

background: the aim of present study was to determine the quality of nursing documents in medical-surgical wards and factors affected this quality. methods: in this descriptive study the quality of nurses' documents in medical-surgical wards of teaching hospitals related to tabriz university of medical sciences was assessed. for data gathering, four checklists assessed four parts of nursing doc...

More and more domain specific applications in the internet make use of Natural Language Processing (NLP) tools (e. g. Information Extraction systems). The output quality of these applications relies on the output quality of the used NLP tools. Often, the quality can be increased by annotating a domain specific corpus. However, annotating a corpus is a time consuming and exhaustive task. To redu...

This paper examines cross-country patterns of economic growth by estimating a stochastic frontier production function for 80 developed and developing countries and decomposing output change into factor accumulation, total factor productivity growth, and production efficiency improvement. In addition, this paper incorporates the quality of inputs in analyzing output growth, where the productivit...

Following Rosen [1981], superstar effects (earnings convex in quality and a few firms reaping a large share of market earnings) occur with imperfect substitution between sellers, low (and possibly declining) marginal cost of output, and marginal cost falling as quality increases. However, markets without such characteristics have superstar effects, and the main result from the superstar model —...

We present an experiment of using transformation-based learning for improving translation quality of a rule-based machine translation system by means of post-processing. Transformation rules are learned based on a parallel corpus of machine translation output and a human-corrected version of the output. The experiment resulted in a significant increase in translation quality of 0.8 measured usi...

Linear AC power supplies can be replaced by their nonlinear switching counterparts due to the lower voltage drops and higher efficiency and power density of switching-mode inverters. Multilevel cascaded H-bridge (CHB) converters are the preferred inverter structure because of modular configuration, control, and protection. The output voltage quality in CHB converters depends on the number of ou...

In the last two years, the Office of Prices and Living Conditions (OPLC) of the U.S. Bureau of Labor Statistics has undertaken a project to define a quality framework for its four price programs. This initiative began with an extensive review of quality concepts and frameworks; we summarize findings from that effort, distinguish between product and process quality, and review associated quality...
