Artificial intelligence techniques for modeling database user behavior
The design and development of the adaptive modeling system is described. This system models how a user accesses a relational database management system in order to improve its performance by discovering use access patterns. In the current system, these patterns are used to improve the user interface and may be used to speed data retrieval, support query optimization and support a more flexible data representation. The system models both syntactic and semantic information about the user's access and employs both procedural and rule-based logic to manipulate the model
Extending the data dictionary for data/knowledge management
Current relational database technology provides the means for efficiently storing and retrieving large amounts of data. By combining techniques learned from the field of artificial intelligence with this technology, it is possible to expand the capabilities of such systems. This paper suggests using the expanded domain concept, an object-oriented organization, and the storing of knowledge rules within the relational database as a solution to the unique problems associated with CAD/CAM and engineering data
Earth science data study
The research proposed in this contract concerning investigations of existing and planned Earth Science and Applications Division (ESAD) data management systems and research into utilities for the access and display of scientific data products was completed. A summary of this work is provided
CINTEX: International Interoperability Extensions to EOSDIS
A large part of the research under this cooperative agreement involved working with representatives of the DLR, NASDA, EDC, and NOAA-SAA data centers to propose a set of enhancements and additions to the EOSDIS Version 0 Information Management System (V0 IMS) Client/Server Message Protocol. Helen Conover of ITSL led this effort to provide for an additional geographic search specification (WRS Path/Row), data set- and data center-specific search criteria, search by granule ID, specification of data granule subsetting requests, data set-based ordering, and the addition of URLs to result messages. The V0 IMS Server Cookbook is an evolving document, providing resources and information to data centers setting up a VO IMS Server. Under this Cooperative Agreement, Helen Conover revised, reorganized, and expanded this document, and converted it to HTML. Ms. Conover has also worked extensively with the IRE RAS data center, CPSSI, in Russia. She served as the primary IMS contact for IRE-CPSSI and as IRE-CPSSI's liaison to other members of IMS and Web Gateway (WG) development teams. Her documentation of IMS problems in the IRE environment (Sun servers and low network bandwidth) led to a general restructuring of the V0 IMS Client message polling system. to the benefit of all IMS participants. In addition to the IMS server software and documentation. which are generally available to CINTEX sites, Ms. Conover also provided database design documentation and consulting, order tracking software, and hands-on testing and debug assistance to IRE. In the final pre-operational phase of IRE-CPSSI development, she also supplied information on configuration management, including ideas and processes in place at the Global Hydrology Resource Center (GHRC), an EOSDIS data center operated by ITSL
A data and information system for processing, archival, and distribution of data for global change research
Work on this project was focused on information management techniques for Marshall Space Flight Center's EOSDIS Version 0 Distributed Active Archive Center (DAAC). The centerpiece of this effort has been participation in EOSDIS catalog interoperability research, the result of which is a distributed Information Management System (IMS) allowing the user to query the inventories of all the DAAC's from a single user interface. UAH has provided the MSFC DAAC database server for the distributed IMS, and has contributed to definition and development of the browse image display capabilities in the system's user interface. Another important area of research has been in generating value-based metadata through data mining. In addition, information management applications for local inventory and archive management, and for tracking data orders were provided
Earth science and application
The University of Alabama in Huntsville (UAH) has completed the research proposed. The major tasks under this contract were: (1) research into visualization of scientific data sets (browse); (2) studies of standard data formatting procedures; and (3) investigations of approaches for submission of scientific data sets for archival. Summaries of each activity are presented along with travel reports and conclusions and recommendations
First Generation Success: Mixed-Methods Information Literacy Skills Assessment for First Year Writing Students
As universities seek to improve retention and graduation rates, more attention is being paid to populations that are statistically less likely to persist, such as first-generation students. Engaging with a campus-wide initiative targeting first-generation college students, librarians at a research university were awarded a grant to study the information literacy skills of this special population and to develop intervention strategies to help retain students.
Partnering with the English department and a campus provisional admission program, librarians developed and taught special sections of the first
year composition course, ENGL 104. These sections were designed to seamlessly embed information literacy concepts into the traditional
ENGL 104 curriculum and to thoroughly assess the impact of this approach. This study was designed using a mixed-methods approach to
better understand the information literacy knowledge and skills of first-generation students and to evaluate the impact of embedding information literacy into a course required for their degree plans
Reference E-Books: The Other Hidden Collection
This presentation was given at the 2010 Brick and Click Libraries Symposium at Northwest Missouri State University, Maryville, Missouri, November 5, 2010Traditional print reference collections have been reduced significantly over the past few years, as the preference for and the availability of electronic resources have increased. Librarians at the University of Kansas are concerned that the growing numbers of reference e-books in the collection are underutilized. There is a clear need to promote these resources to both library reference staff and users who are unaware of the numerous reference titles purchased individually or contained in electronic packages, such as Credo Reference. Although records for individual titles, from online reference collections and those purchased separately, are loaded into the online catalog, there is currently no easy way to browse the electronic reference collection
