Scientific Data Mining in Astronomy
SCIENTIFIC DATA MINING IN ASTRONOMY Kirk D. Borne Department of Computational and Data Sciences, George Mason University, Fairfax, VA 22030, USA [email protected] Abstract We describe the application of data mining algorithms to research prob- lems in astronomy. We posit that data mining has always been fundamen- tal to astronomical research, since data mining is the basis of evidence- based discovery, including classification, clustering, and novelty discov- ery. These algorithms represent a major set of computational tools for discovery in large databases, which will be increasingly essential in the era of data-intensive astronomy. Historical examples of data mining in astronomy are reviewed, followed by a discussion of one of the largest data-producing projects anticipated for the coming decade: the Large Synoptic Survey Telescope (LSST). To facilitate data-driven discoveries in astronomy, we envision a new data-oriented research paradigm for astron- omy and astrophysics – astroinformatics. Astroinformatics is described as both a research approach and an educational imperative for modern data-intensive astronomy. An important application area for large time- domain sky surveys (such as LSST) is the rapid identification, charac- terization, and classification of real-time sky events (including moving objects, photometrically variable objects, and the appearance of tran- sients). We describe one possible implementation of a classification broker for such events, which incorporates several astroinformatics techniques: user annotation, semantic tagging, metadata markup, heterogeneous data integration, and distributed data mining. Examples of these types of collaborative classification and discovery approaches within other science disciplines are presented. arXiv:0911.0505v1 [astro-ph.IM] 3 Nov 2009 1 Introduction It has been said that astronomers have been doing data mining for centuries: “the data are mine, and you cannot have them!”. -

Data Quality Through Data Integration: How Integrating Your IDEA Data Will Help Improve Data Quality
center for the integration of IDEA Data Data Quality Through Data Integration: How Integrating Your IDEA Data Will Help Improve Data Quality July 2018 Authors: Sara Sinani & Fred Edora High-quality data is essential when looking at student-level data, including data specifically focused on students with disabilities. For state education agencies (SEAs), it is critical to have a solid foundation for how data is collected and stored to achieve high-quality data. The process of integrating the Individuals with Disabilities Education Act (IDEA) data into a statewide longitudinal data system (SLDS) or other general education data system not only provides SEAs with more complete data, but also helps SEAs improve accuracy of federal reporting, increase the quality of and access to data within and across data systems, and make better informed policy decisions related to students with disabilities. Through the data integration process, including mapping data elements, reviewing data governance processes, and documenting business rules, SEAs will have developed documented processes and policies that result in more integral data that can be used with more confidence. In this brief, the Center for the Integration of IDEA Data (CIID) provides scenarios based on the continuum of data integration by focusing on three specific scenarios along the integration continuum to illustrate how a robust integrated data system improves the quality of data. Scenario A: Siloed Data Systems Data systems where the data is housed in separate systems and State Education Agency databases are often referred to as “data silos.”1 These data silos are isolated from other data systems and databases. -
Master Data Management Whitepaper.Indd
Creating a Master Data Environment An Incremental Roadmap for Public Sector Organizations Master Data Management (MDM) is the processes and technologies used to create and maintain consistent and accurate representations of master data. Movements toward modularity, service orientation, and SaaS make Master Data Management a critical issue. Master Data Management leverages both tools and processes that enable the linkage of critical data through a unifi ed platform that provides a common point of reference. When properly done, MDM streamlines data management and sharing across the enterprise among different areas to provide more effective service delivery. CMA possesses more than 15 years of experience in Master Data Management and more than 20 in data management and integration. CMA has also focused our efforts on public sector since our inception, more than 30 years ago. This document describes the fundamental keys to success for developing and maintaining a long term master data program within a public service organization. www.cma.com 2 Understanding Master Data transactional data. As it becomes more volatile, it typically is considered more transactional. Simple Master Data Behavior entities are rarely a challenge to manage and are rarely Master data can be described by the way that it interacts considered master-data elements. The less complex an with other data. For example, in transaction systems, element, the less likely the need to manage change for master data is almost always involved with transactional that element. The more valuable the data element is to data. This relationship between master data and the organization, the more likely it will be considered a transactional data may be fundamentally viewed as a master data element. -

Data Management, Analysis Tools, and Analysis Mechanics
Chapter 2 Data Management, Analysis Tools, and Analysis Mechanics This chapter explores different tools and techniques for handling data for research purposes. This chapter assumes that a research problem statement has been formulated, research hypotheses have been stated, data collection planning has been conducted, and data have been collected from various sources (see Volume I for information and details on these phases of research). This chapter discusses how to combine and manage data streams, and how to use data management tools to produce analytical results that are error free and reproducible, once useful data have been obtained to accomplish the overall research goals and objectives. Purpose of Data Management Proper data handling and management is crucial to the success and reproducibility of a statistical analysis. Selection of the appropriate tools and efficient use of these tools can save the researcher numerous hours, and allow other researchers to leverage the products of their work. In addition, as the size of databases in transportation continue to grow, it is becoming increasingly important to invest resources into the management of these data. There are a number of ancillary steps that need to be performed both before and after statistical analysis of data. For example, a database composed of different data streams needs to be matched and integrated into a single database for analysis. In addition, in some cases data must be transformed into the preferred electronic format for a variety of statistical packages. Sometimes, data obtained from “the field” must be cleaned and debugged for input and measurement errors, and reformatted. The following sections discuss considerations for developing an overall data collection, handling, and management plan, and tools necessary for successful implementation of that plan. -
Master Data Management Services (MDMS) System
ADAMS ML19121A465 U.S. Nuclear Regulatory Commission Privacy Impact Assessment Designed to collect the information necessary to make relevant determinations regarding the applicability of the Privacy Act, the Paperwork Reduction Act information collection requirements, and records management requirements. Master Data Management Services (MDMS) System Date: April 16, 2019 A. GENERAL SYSTEM INFORMATION 1. Provide a detailed description of the system: The Nuclear Regulatory Commission (NRC) has established the Master Data Management Services (MDMS) system to address both short and long-term enterprise data management needs. The MDMS is a major agencywide initiative to support the processes and decisions of NRC through: • Improving data quality • Improving re-use and exchange of information • Reducing or eliminating the storage of duplicate information • Providing an enterprise-wide foundation for information sharing • Establishing a data governance structure The MDMS provides an overall vision for, and leadership focused on, an enterprise solution that establishes authoritative data owners, delivers quality data in an efficient manner to the systems that require it, and effectively meets business needs. The MDMS is also focused on data architecture and includes projects that will identify and define data elements across the agency. The MDMS system is a web-based application accessible to representatives from every NRC office—that provides standardized and validated dockets and data records that support dockets, including licenses, contact and billing information, to all downstream NRC systems that require that data. The NRC collects digital identification data for individuals to support the agency core business operations, issue credentials, and administer access to agency‘s physical and logical resources. To support this need, the MDMS system also serves as a centralized repository for the accessibility of organization and personnel data.
