Next Generation Repositories: Behaviours and Technical Recommendations of the COAR Next Generation Repositories Working Group

Description: The widespread deployment of repository systems in higher education and research institutions provides the foundation for a distributed, globally networked infrastructure for scholarly communication. However, repository platforms are still using technologies and protocols designed almost twenty years ago, before the boom of the Web and the dominance of Google, social networking, semantic web and ubiquitous mobile devices.In April 2016, COAR launched the Next Generation Repositories Working Group to identify the core functionalities for the next generation of repositories, as well as the architectures and technologies required to implement them. This report presents the results of work by this group over the last 1.5 years. The Next Generation Repositories Working Group has explicitly focused on the generic technologies required by all repositories to support the adoption of common behaviors. This report describes 11 new behaviors, as well as the technologies, standards and protocols that will facilitate the development of new services on top of the collective network, including social networking, peer review, notifications, and usage assessment. 1. Exposing Identifiers 2. Declaring Licenses at a Resource Level 3. Discovery through Navigation 4. Interacting with Resources (Annotation, Commentary and Review) 5. Resource Transfer 6. Batch Discovery 7. Collecting and Exposing Activities 8. Identification of Users 9. Authentication of Users 10. Exposing Standardized Usage Metrics 11. Preserving Resources The behaviors and technologies in this report are a snapshot of the current status of technology, standards and protocols available, but we are aware that technologies will continue to evolve.

A Study of Physicians' Serendipitous Knowledge Discovery: An Evaluation of Spark and the IF-SKD Model in a Clinical Setting

Description: This research study is conducted to test Workman, Fiszman, Rindflesch and Nahl's information flow-serendipitous knowledge discovery (IF-SKD) model of information behavior, in a clinical care context. To date, there have been few attempts to model the serendipitous knowledge discovery of physicians. Due to the growth and complexity of the biomedical literature, as well as the increasingly specialized nature of medicine, there is a need for advanced systems that can quickly present information and assist physicians to discover new knowledge. The National Library of Medicine's (NLM) Lister Hill Center for Biocommunication's Semantic MEDLINE project is focused on identifying and visualizing semantic relationships in the biomedical literature to support knowledge discovery. This project led to the development of a new information discovery system, Spark. The aim of Spark is to promote serendipitous knowledge discovery by assisting users in maximizing the use of their conceptual short-term memory to iteratively search for, engage, clarify and evaluate information presented from the biomedical literature. Using Spark, this study analyzes the IF- SKD model by capturing and analyzing physician feedback. The McCay-Peet, Toms and Kelloway's Perception of Serendipity and Serendipitous Digital Environment (SDE) questionnaires are used. Results are evaluated to determine whether Spark contributes to physicians' serendipitous knowledge discovery and the ability of the IF-SKD ability to capture physicians' information behavior in a clinical setting.

Information Gain Based Dimensionality Selection for Classifying Text Documents

Description: Selecting the optimal dimensions for various knowledge extraction applications is an essential component of data mining. Dimensionality selection techniques are utilized in classification applications to increase the classification accuracy and reduce the computational complexity. In text classification, where the dimensionality of the dataset is extremely high, dimensionality selection is even more important. This paper presents a novel, genetic algorithm based methodology, for dimensionality selection in text mining applications that utilizes information gain. The presented methodology uses information gain of each dimension to change the mutation probability of chromosomes dynamically. Since the information gain is calculated a priori, the computational complexity is not affected. The presented method was tested on a specific text classification problem and compared with conventional genetic algorithm based dimensionality selection. The results show an improvement of 3% in the true positives and 1.6% in the true negatives over conventional dimensionality selection methods.

Students' Criteria for Course Selection: Towards a Metadata Standard for Distributed Higher Education

Description: By 2007, one half of higher education students are expected to enroll in distributed learning courses. Higher education institutions need to attract students searching the Internet for courses and need to provide students with enough information to select courses. Internet resource discovery tools are readily available, however, users have difficulty selecting relevant resources. In part this is due to the lack of a standard for representation of Internet resources. An emerging solution is metadata. In the educational domain, the IEEE Learning Technology Standards Committee (LTSC) has specified a Learning Object Metadata (LOM) standard. This exploratory study (a) determined criteria students think are important for selecting higher education courses, (b) discovered relationships between these criteria and students' demographic characteristics, educational status, and Internet experience, and (c) evaluated these criteria vis-à-vis the IEEE LTSC LOM standard. Web-based questionnaires (N=209) measured (a) the criteria students think are important in the selection of higher education courses and (b) three factors that might influence students' selections. Respondents were principally female (66%), employed full time (57%), and located in the U.S. (89%). The chi square goodness-of-fit test determined 40 criteria students think are important and exploratory factor analysis determined five common factors among the top 21 criteria, three evaluative factors and two descriptive. Results indicated evaluation criteria are very important in course selection. Spearman correlation coefficients and chi-square tests of independence determined the relationships between the importance of selection criteria and demographic characteristics, educational status, and Internet experience. Four profiles emerged representing groups of students with unique concerns. Side by side analysis determined if the IEEE LTSC LOM standard included the criteria of importance to students. The IEEE LOM by itself is not enough to meet students course selection needs. Recommendations include development of a metadata standard for course evaluation and accommodation of group differences in ...

Art Museum Resources and Teacher Use.

Description: I proposed that both Bruner's (1963) idea of the spiral curriculum and Yenawine's (1992) theories of teaching for visual literacy in the museum set the stage for significant learning for students when used together. If school teachers lay a foundation of knowledge about a museum object, especially through museum resources, then the student may transform and apply this 'prior knowledge' (explicit memories from the classroom) while on the museum visit tour. When docents utilize Yenawine's (1992) methods toward the goal of visual literacy, the semantic knowledge of the classroom is then fused with museum learning, building stronger memories and facilitating deeper understanding as students learn about museum objects. This research explored the correlation of these two theories in a qualitative manner based on observations of actual museum visit preparation in classrooms in Casper, Wyoming, and how it related to a museum tour at the Nicolaysen Art Museum and Discovery Center. The research revealed that conditions do exist within the community that would facilitate Bruner's (1963) idea of a learning spiral, yet not in the manner envisioned. The observed conditions toward a spiral was accomplished through the participant teachers relating the museum exhibit to their operational curriculum in a variety of curricular areas, such as language arts and science, when docents related the tour to classroom learning, and not through museum resources or Yenawine's (1992) methods toward increasing visual literacy, as was previously considered.

Discovery of Resources and Conflict in the Interstate System, 1816-2001

Description: This study tests a theory detailing the increased likelihood of conflict following an initial resource discovery in the discovering nation and its region. A survey of prior literature shows a multitude of prior research concerning resources and nations' willingness to initiate conflict over those resources, but this prior research lacks any study concerning the effects of the discovery of resources on interstate conflict. The theory discusses the increased likelihood of conflict in the discovering nation as both target and initiator. It further looks at the increased chance of conflict in the discoverer's region due to security dilemmas and proxy wars. The results show strong support for the theory, suggesting nations making new resource discoveries must take extra care to avoid conflict.

Interactive Analysis of Large Network Data Collections UsingQuery-Driven Visualization

Description: Realizing operational analytics solutions where large and complex data must be analyzed in a time-critical fashion entails integrating many different types of technology. Considering the extreme scale of contemporary datasets, one significant challenge is to reduce the duty cycle in the analytics discourse process. This paper focuses on an interdisciplinary combination of scientific data management and visualization/analysis technologies targeted at reducing the duty cyclein hypothesis testing and knowledge discovery. We present an application of such a combination in the problem domain of network traffic data analysis. Our performance experiment results, including both serial and parallel scalability tests, show that the combination can dramatically decrease the analytics duty cycle for this particular application. The combination is effectively applied to the analysis of network traffic data to detect slow and distributed scans, which is a difficult-to-detect form of cyber attack. Our approach is sufficiently general to be applied to a diverse set of data understanding problems as well as used in conjunction with a diverse set of analysis and visualization tools.
