Evaluation Measure

According to Mercier and Sperber (2009, 2011, 2017), people have an immediate and intuitive feeling about the strength of an argument. These intuitive evaluations are not captured by current evaluation methods of argument strength, yet they could be important to predict the extent to which people accept the claim supported by the argument. In an exploratory study, therefore, a newly developed intuitive evaluation method to assess argument strength was compared to an explicit argument strength evaluation method (the PAS scale; Zhao et al., 2011), on their ability to predict claim acceptance (predictive validity) and on their sensitivity to differences in the manipulated quality of arguments (construct validity). An experimental study showed that the explicit argument strength evaluation performed well on the two validity measures. The intuitive evaluation measure, on the other hand, was not found to be valid. Suggestions for other ways of constructing and testing intuitive evaluation measures are presented.

Major Industry

Meat export is a major industry in Australia, and meat packaging and freezing is an energy intensive activity, requiring an objective technical investigation. This study was undertaken in order to assess the relative merits of plate and air blast freezing methods used in industry. To describe the efficiency and the technical superiority of one method over the other, in this paper, the details of an experimental study involving time-temperature measurement of meat boxes inside a plate freezer and a blast freezer under normal working conditions are provided. For the configurations used in this study, it is shown that the freezing time is much shorter for plate freezing, and also there is a much smaller variation in freezing time of various boxes compared to those for blast freezing. The smaller variation in freezing time of various boxes in each batch would help preserve the quality of meat being frozen. Also, it is explained that despite the initial higher capital cost of plate freezing, the total cost over the life of the equipment is much smaller for plate freezing compared to blast freezing.

Empirical Experiment

A study of people solving facility layout problems was made to estimate the effects of problem features on the quality of solutions obtained by novice and experienced subjects. An empirical experiment was conducted. Three features of these problems which were systematically varied in this study were: 1. Problem size, 2. Fraction of strong inter-departmental relationships, and 3. Fraction of departments requiring a non-standard amount of floor space. Both quantitative and subjective layout evaluations were made. It was found that layout quality was not affected by feature 3 for any values of the other features, using either evaluation method, and with either novice or experienced subjects. However, feature 2 proved to be significant for all experimental conditions, both evaluation methods, and with both subject groups. Feature 1 was a significant feature in some situations, but was not significant in others. Some differences in problem solving approaches were observed. There was a significant relationship between the design of higher quality layouts by experienced subjects and the use of a Relationship Diagram. Reducing the problem size and/or percentage of strong inter-departmental relationships in a problem may make a higher quality layout easier to achieve.

The purpose of this chapter is to provide an overview of prevalent measures for evaluating the quality of system output in seven key text mining task domains. For each task domain, a selection of widely used, well applicable measures is presented, and their strengths and weaknesses are discussed. Performance evaluation is essential for text mining system development and comparison, but the selection of a suitable performance evaluation measure is not a straightforward task. Therefore this chapter also attempts to give guidelines for measure selection. As measures are under constant development in many task domains and it is important to take the task domain characteristics and conventions into account, references to relevant performance evaluation events and literature are provided.

AbstractIntroduction: Cardiopulmonary resuscitation is a direct intervention for the prevention or postponement of death in patients with cardiac arrest. The fatigue of rescue workers is of high significance when performing cardiopulmonary resuscitation effectively. The present study aimed to investigate the effect of a cardiac massage facilitator device on the fatigue of rescue workers in cardiopulmonary resuscitation.Materials and Methods: This experimental study was carried out on 30 emergency medical aid non-continuous bachelor students, divided equally into two groups: one group performed cardiac massage using the device and the other without the device. Fatigue levels were assessed using a visual analog scale to evaluate fatigue severity.Results: The mean age of participants was 23.42 ± 2.02 years, the mean height was 175 ± 4.43 cm, and the mean weight was 65.45 ± 5.02 kg. There was a statistically significant difference between the mean fatigue scores of the two groups: 0.06 with the device vs. 0.57 without the device.Conclusion: Our results suggest that the cardiac massage facilitator device presented in this study could be effective in improving the quality of cardiac massage and be helpful in cardiopulmonary resuscitation.

Traditional Evaluation

Introduction The robustness of record linkage evaluation measures is of high importance since linkage techniques are assessed based on these. However, minimal research has been conducted to evaluate the suitability of existing evaluation measures in the context of linking groups of records. Linkage quality is generally evaluated based on traditional measures such as precision and recall. As we show, these traditional evaluation measures are not suitable for evaluating groups of linked records because they evaluate the quality of individual record pairs rather than the quality of records grouped into clusters. Objectives We highlight the shortcomings of traditional evaluation measures and then propose a novel method to evaluate clustering quality in the context of group-based record linkage. Methods The proposed linkage evaluation method assesses how well individual records have been allocated into predicted groups/clusters with respect to ground-truth data. We first identify the best representative predicted cluster for each ground-truth cluster and, based on the resulting mapping, each record in a ground-truth cluster is assigned to one of seven categories. These categories reflect how well the linkage technique assigned records into groups. Results We empirically evaluate our proposed method using real-world data and show that it better reflects the quality of clusters generated by three group-based record linkage techniques. We also show that traditional measures such as precision and recall can produce ambiguous results whereas our method does not. Conclusions The proposed evaluation method provides unambiguous results regarding the assessed group-based record linkage approaches. The method comprises of seven categories which reflect how each record was predicted, providing more detailed information about the quality of the linkage result. This will help to make better-informed decisions about which linkage technique is best suited for a given linkage application.

Quality Objective

To evaluate the compatibility quality of various H.264 codecs, and promote H.264 codec benign competition in the market, this paper proposes an objective evaluation method. Firstly, this method adopts video distributor, video capture card and other facilities to collect two-way videos, one of which is reference video, and the other is the video encoded and decoded respectively; Then it utilizes SSIM algorithm to find "the best similar frame" between the two videos in order to solve the problem of “Homologous Asynchronous”; Finally, it establishes codec compatibility matrix which can objectively evaluate codec compatibility quality using the proposed five indexes. Experiments show that the proposed method is simple, and can effectively evaluate codec compatibility quality. 
