An Analysis of Using Expert Systems and Intelligent Agents for the Virtual Library Project at the Naval Surface Warfare Center-Carderock Division

The Virtual Library Project1 at the Naval Surface Warfare Center/Carderock Division (NSWC/CD) is being developed to facilitate the incorporation and use of library documents via the Internet. These documents typically relate to the design and manufacture of ships for the U.S. Navy Fleet. As such, the libraries will store documents that contain not only text but also images, graphs and design configurations. Because of the dynamic nature of digital documents, particularly those related to design, rapid and effective cataloging of these documents becomes challenging. We conducted a research study to analyze the use of expert systems and intelligent agents to support the function of cataloging digital documents. This chapter provides an overview of past research in the use of expert systems and intelligent agents for cataloging digital documents and discusses our recommendations based on NSWC/CD’s requirements

The survival of the fastest: Unveiling the determinants of Unicorns and Gazelles’ early success

What are the determinants of Unicorns and Gazelles’ early success? This review article examines the factors that contribute to the success of Unicorns and Gazelles in their early life stage. Indeed, despite their unique characteristics and significant impact on the global economy, Unicorns and Gazelles have yet to be thoroughly examined in terms of their (exceptional) survival factors. To bridge this literature gap, we systematically reviewed 66 articles, comparing Unicorns' and Gazelles' survival determinants and proposing a conceptual framework for their life cycle. Attracted by the exceptional characteristics of these new ventures, such as the fast scalability provided by their business models, early investors play a key role in helping them overcome initial challenges. However, this reliance on investors presents a double-edged sword, as withdrawing their support can lead to significant disruptions. This understanding provides valuable insights for entrepreneurs, investors, and policymakers navigating the complexities of the start-up world, ultimately increasing the likelihood of venture success and achieving a champion status. By shedding light on these exceptional ventures, our study contributes to a more comprehensive understanding of the factors driving the survival dynamics of Unicorns and Gazelles

Exploring Pelagios: a visual browser for geo-tagged datasets

When dealing with networked information spaces, there are two challenges a data navigation system must address: first, it needs to provide the user with a quick high-level overview of the nature and struc- ture of the data. Second, it must offer mechanisms to easily drill down and navigate to specific detail information. In this demonstration, we present the Pelagios Graph Explorer, a prototype visual exploration tool for place metadata which is derived from ancient world research datasets brought together by the Pelagios Project. Furthermore, we report on ongoing work on the Pelagios API. The API enables external re-use of the Pelagios place metadata, and provides a basis for future development of - and experimentation with - alternative navigation tools for the networked place metadata from the Pelagios project

Mogwaï: a Framework to Handle Complex Queries on Large Models

International audienceWhile Model Driven Engineering is gaining more industrial interest, scalability issues when managing large models have become a major problem in current modeling frameworks. Scalable model persistence has been achieved by using NoSQL backends for model storage, but existing modeling framework APIs have not evolved accordingly, limiting NoSQL query performance benefits. In this paper we present the Mogwaï a scalable and efficient model query framework based on a direct translation of OCL queries to Gremlin, a query language supported by several NoSQL databases. Generated Gremlin expressions are computed inside the database itself, bypassing limitations of existing framework APIs and improving overall performance, as confirmed by our experimental results showing an improvement of execution time up to a factor of 20 and a reduction of the memory overhead up to a factor of 75 for large models

Rising to the Challenge: Re-envisioning Public Libraries

This report explores the essential role of public libraries in a networked world and begin to re-envision the 21st century library in a hyper-connected environment and dramatically changing world. The report is intended to raise the profile of public libraries to the center of the knowledge society, highlight the opportunities and possibilities, increase support for an expanded library role in a networked world and spark a national conversation and action to re-envision the 21st century library as a center of learning, innovation and creativity. While the report's focus is on public libraries, we acknowledge the importance of school and research libraries in the broader conversations around the future of libraries and communities

A web-based GIS as a management tool for rock art sites in the Ukhahlamba-Drakensberg Park.

Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.The importance of managing and conserving cultural heritage can not be overemphasised. It is this realisation that has prompted the United Nations Educational, Scientific and Cultural Organisation (UNESCO) to declare identified sites of cultural importance as World Heritage Sites. The uKhahlamba-Drakensberg Park (UDP) was declared such a site in 2000, with its natural properties and cultural heritage as the criteria for inscription. The cultural heritage centres on the vast quantity of rock art that is renowned for its quality and diversity of subject. It is an important consideration for future generations to have the opportunity to view and understand this rich history and culture. There are increasing human and natural impacts on this non-renewable resource and to minimise these impacts and thus ensure the longevity of the resource it is necessary to develop a multi faceted selection of management and conservation tools. This realisation led the Programme of Geornatics, University of KwaZulu-Natal to conceptualise a project to develop a web-based Geographical Information System (GIS) specifically aimed at assisting in the management and conservation of rock art sites for the Valley of Pools in the Cathedral Peak Conservation Area of the UDP. Data for the project was captured in the field using Global Positioning System (GPS), digital camera and video camera as well as conventional hardcopy documentation. Existing digital spatial data and descriptive data were also collected from relevant stakeholders and a commercial organization. A pilot spatial database was then developed using ArcGIS@9 and Microsoft Access@, and later tested using a set of integrated simulated queries reflective of routine questions that users may request. Upon obtaining satisfactory responses to the queries, the integrated database was migrated and authored in ArcIMS®9 where it was further tested, and subsequently access was given to selected external professionals, both nationally and internationally, from various backgrounds, for evaluation purposes. Feedback from this process was favourably obtained

A succinct data structure for self-indexing ternary relations

The final publication is available via http://dx.doi.org/10.1016/j.jda.2016.10.002[Abstract] The representation of binary relations has been intensively studied and many different theoretical and practical representations have been proposed to answer the usual queries in multiple domains. However, ternary relations have not received as much attention, even though many real-world applications require the processing of ternary relations. In this paper we present a new compressed and self-indexed data structure that we call Interleaved K2-tree (IK2-tree), designed to compactly represent and efficiently query general ternary relations. The IK2-tree is an evolution of an existing data structure, the K2-tree [6], initially designed to represent Web graphs and later applied to other domains. The IK2-tree is able to extend the K2-tree to represent a ternary relation, based on the idea of decomposing it into a collection of binary relations but providing indexing capabilities in all the three dimensions. We present different ways to use IK2-tree to model different types of ternary relations using as reference two typical domains: RDF and Temporal Graphs. We also experimentally evaluate our representations comparing them in space usage and performance with other solutions of the state of the art.Ministerio de Economía y Competitividad; TIN2013-46238-C4-3-RXunta de Galicia; GRC2013/053Chile.

Career Decision-Making of Higher Education Professionals of Philippine Descent: The Untold Stories of an Asian Pacific Islander Community

Using a critical race theory (CRT) framework and a narrative and phenomenological methodology, this study explored the career decision-making of professionals of Philippine descent along the higher education career pipeline in the United States. The stories of these professionals create a counter-narrative to the stereotypes of Asian and Pacific Islanders (APIs) in higher education. The career pipeline in higher education has remained relatively homogeneous, especially at executive levels of administration. Statistics show that APIs make up less than 1% of all college presidents, of that 1%, less than a handful identify as Filipinx. This statistic alone does not completely tell the whole story of Filipinx individuals in higher education because the data reported on faculty, staff, and administrators is aggregated, which means more than 48 ethnic identities are included in the API racial categories. Research on aggregated populations may mask the diverse experiences that exist between various ethnic subgroups. This study disaggregated the API racial groups to look specifically at a sample of Filipinx professionals and their experiences along the higher education career pipeline. As higher education becomes increasingly diverse at the student level, there is a greater need for there to be representation at all levels of the higher education career pipeline. This research is the first of its kind to account for and explore career decision-making experiences of Filipinx higher education professionals. This qualitative study looked at career decision-making through a life course perspective using semi-structured interviews of 20 Filipinx higher education professionals at various career life stages. The participants are professionals in higher education who have worked at least five years in colleges and universities. The collected stories of these professionals shed light on the importance of disaggregating research data to share stories that have yet to be told, explore how Filipinx individuals choose a career in higher education, and identify factors that support career advancement thus diversifying the higher education career pipeline up to the college presidency
