This paper addresses the need for a manageable method of evaluating the overall image quality of hardcopy output from printer systems so that the systems can be compared in a meaningful way. Image quality metrics are widely used and are very objective, but are unsuitable for this purpose because there is no good way of extracting overall image quality from the large number of possible metrics. ...

We consider how far two attributes of text quality commonly used in MT evaluation – intelligibility and fidelity – apply within NLG. While the former appears to transfer directly, the latter needs to be completely re-interpreted. We make a crucial distinction between the needs of symbolic authors and those of end-readers. We describe a form of textual feedback, based on a controlled language us...

A visualization tool for EPA’s Community Multiscale Air Quality modeling system, VisCMAQ, which is developed in this study as an OpenGL based visualization tool that has the capability to render data on both regular and irregular grids. The goal of this project is to enhance the VisCTM model, which was created last summer with additional flexibilities such as reading from NetCDF files. Also, th...

Females who choose highly ornamented mates may gain resources that improve offspring production and survival. Studies have focused on the relationship between male quality and the complexity of sexual ornaments; however, less is known of the communicative content of courtship displays, and whether they indicate the quality of resources males can provide to mates. Here, we used blue-black grassq...

In this paper, a three ring-resonator serially coupled is considered as an optical filter. We are going to improve the performance of the designed optical filter by increasing the quality factor and finesse of filtered wavelengths. The first and last rings are coupled to the bus waveguides that carry the input and output fields. The effect of coupling parameters and ring radii on the filtering ...

This paper presents techniques for referencefree, automatic prediction of Machine Translation output quality at both sentenceand document-level. In addition to helping with document-level quality estimation, sentencelevel predictions are used for system selection, improving the quality of the output translations. We present three system selection techniques and perform evaluations that quantify...

Large amounts of structured information is buried in unstructured text. Information extraction systems can extract structured relations from the documents and enable sophisticated, SQL-like queries over unstructured text. Information extraction systems are not perfect and their output has imperfect precision and recall (i.e., contains spurious tuples and misses good tuples). Typically, an extra...

the sources of output growth of iranian agriculture over the years 1986-2001 has been examined, using a decomposition method within the input-output (io) framework. the three comparable io tables of 1986, 1991, and 2001 have been employed as the main data sources. output changes from a demand side perspective, and decomposition of the growth of output into components attributable to consumption...

Every day there are more techniques that can work with low quality data. As a result, issues related to data quality have become more crucial and have consumed a majority of the time and budget of data mining projects. One problem for researchers is the lack of low quality data in order to test their techniques with this data type. Also, as far as we know, there is no software tool focused on t...
