Accuracy Evaluation for Sensed Data
2014To address the problem for accuracy evaluation, we propose a systematic method. With MSE, a parameter to measure the accuracy in statistics, we design the accuracy evaluation framework for multi-modal data. Within this framework, we classify data types into three categories and develop accuracy evaluation algorithms for each category in cases of in ...

A study on the accuracy of Flickr's geotag data
Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval, 2013Obtaining geographically tagged multimedia items from social Web platforms such as Flickr is beneficial for a variety of applications including the automatic creation of travelogues and personalized travel recommendations. In order to take advantage of the large number of photos and videos that do not contain (GPS-based) latitude/longitude coordinates,

On the accuracy of data sensing in the presence of mobility
2016 7th International Conference on the Network of the Future (NOF), 2016Smart Cities aim to improve living conditions by enabling new intelligent services for citizens. These services typically require environmental awareness obtained from distributed sensing systems. The implementation of such sensing systems on a city-wide scale is challenging, as the number of sensors needed can become unpractical.

Evaluating the Completeness and Accuracy of MedWatch Data
American Journal of Therapeutics, 2014The Food and Drug Administration's MedWatch system--a voluntary surveillance program--received 600,000 adverse event reports on marketed drugs and devices in 2011. The Food and Drug Administration credits the MedWatch system with improving awareness, and expediting early detection, of drug and device risks and in illuminating the adoption of medical ...

Testing the accuracy of a data assimilation algorithm
International Journal of Computational Science and Engineering, 2007Variational data assimilation techniques have been successfully used in connection with comprehensive research projects in different fields of science and engineering. The use of the variational data assimilation approach is becoming more and more popular also in the attempts to improve the accuracy of the results obtained by running large-scale air ...

Assessment of the accuracy of GeoNames gazetteer data
Proceedings of the 7th Workshop on Geographic Information Retrieval, 2013Gazetteers are the basis of many geospatial applications and serve an important role to collect and make available knowledge about the physical world such as place names and their coordinates. GeoNames is one of the largest and most often used gazetteer and it is generally assumed to be of sufficient quality.

Analysis of Accuracy of Data Reduction Techniques
1999There is a growing interest in the analysis of data in warehouses. Data warehouses can be extremely large and typical queries frequently take too long to answer. Manageable and portable summaries return interactive response times in exploratory data analysis.

The Impact of Data Accuracy on System Learning
Journal of Management Information Systems, 1993The purpose of this paper is to study the impact of database accuracy on system learning. The paper assumes a basic model of an information system with a database, a rulebase, and an embedded machine learning approach that is used to add rules to the rulebase.
