The Interplay of Big Data, WorldCat, and Dewey
Get PDFAs the premier example of big data in the bibliographic world, WorldCat has the potential to support knowledge discovery in many arenas. After giving evidence for a big data characterization of WorldCat, the paper explores this knowledge discovery potential from two perspectives related to the Dewey Decimal Classification (DDC) system: (1) how WorldCat data can inform development of the DDC (classification analytics) and (2) how DDC-classified content in WorldCat can shed light on the bibliographic world itself (collection analytics). In the realm of classification analytics, WorldCat data support decisions to modify the DDC by expanding or reducing the number of classes, adding topical coverage, or adding subject access points; data analysis can support recognition of (1) trending topics and (2) the faceted structure of subject domains. In the realm of collection analytics, the paper considers as possible applications the use of the DDC in the topical "fingerprinting" of categorized content in WorldCat or in performing a bibliographic gap analysis
A REVIEW OF GLASS COMPOSITIONS AROUND THE SOUTH CHINA SEA REGION (THE LATE 1ST MILLENNIUM BC TO THE 1ST MILLENNIUM AD): PLACING IRON AGE GLASS BEADS FROM TAIWAN IN CONTEXT
Get PDFWith more published chemical analyses of glass beads in Southeast Asia and southern China in the last decade, it is becoming possible to discuss the regional and temporal patterns of prehistoric glass beads in these areas. This article focuses the 1st millennium AD, reviewing the chemical composition of glass in Taiwan, Southeast Asia and southern China, in an attempt to understand the potential relationships between the three regions

THE ORGANISATION OF DRILL PRODUCTION AT A NEOLITHIC LITHIC WORKSHOP SITE OF BAI BEN, CAT BA ISLAND, VIETNAM
Get PDFWe investigate stone drill point production, use, maintenance, and discard from a technological perspective at the Late Neolithic workshop of Bai Ben on Cat Ba Island, Northeastern Vietnam. Bai Ben contains over 18,000 retouched chert flakes classified as drill points and dating to c.3000BP. Large scale production of drills most likely took place for reasons of mass production of drilled organic and inorganic objects. Few of such drilled objects are found at the site, perhaps due to poor organic preservation or removal of finished objects for trade and exchange. An analysis of attribute on drills and cores examines the time-ordering of dimensional and morphological changes as reduction continued at the site. The research finds that drills were produced from a diverse range of nodules sizes, blanks, core technologies and raw materials, but similar blanks were selected to produce very similar drill point forms
Big Classification: Using the Empirical Power of Classification Interaction
Get PDFClassification as a cultural artifact serves an epistemological role as disseminator of the culture it embodies. A theory of classification interaction has been proposed that would combine empirical iterations of bibliographic characteristics as factors interacting with traditional conceptual elements in classifications. Nine million UDC numbers extracted from the OCLC WorldCat are sampled and deconstructed, to look for correlations with content-designated components of the associated bibliographic records. Chi-squared is used to locate statistically-significant correlations among nominal-level variables. Results demonstrate a series of footprints of predictable associations. A complex network of associations is revealed and visualized. The results are promising and point to a series of more complex investigations
Exploring the Development and Maintenance Practices in the Gene Ontology
Get PDFThe Gene Ontology (GO) is one of the most widely used and successful bio-ontologies in biomedicine and molecular biology. What is special about GO as a knowledge organization (KO) system is its collaborative development and maintenance practices, involving diverse communities in collectively developing the Ontology and controlling its quality. Guided by Activity Theory and a theoretical Information Quality Assessment Framework, this study conducts qualitative content analysis of GO’s curation discussions. The study found that GO has developed various tools and mechanisms to gain expert feedback and engage various communities in developing and maintaining the Ontology in an efficient and less expensive way. The findings of this study can inform KO system designers, curators, and ontologists in establishing functional requirements and quality assurance infrastructure for bioontologies and formulating best practices for ontology development
