TL;DR: The temporal aspects of indexing and classification in information systems are discussed and two constructs along which to craft metrics to measure scheme change are proposed: collocative integrity and semantic gravity.
Abstract: In this paper we discuss the temporal aspects of indexing and classification in information systems Basing this discussion off of the three sources of research of scheme change: of indexing: (1) analytical research on the types of scheme change and (2) empirical data on scheme change in systems and (3) evidence of cataloguer decision-making in the context of scheme change From this general discussion we propose two constructs along which we might craft metrics to measure scheme change: collocative integrity and semantic gravity The paper closes with a discussion of these constructs

TL;DR: A scientometric study of 1198 articles on cosmology research in India spanning over the years 1999 to 2012 downloaded from Web of Science has been executed in this article, which reveals a uniform growth of literature over the said time span with a little droop in the year 2010.
Abstract: The scientometric study of 1198 articles on Cosmology research in India spanning over the years 1999 to 2012 downloaded from Web of Science has been executed in this paper. The study analyses literature growth trends, which reveals a uniform growth of literature over the said time span with a little droop in the year 2010. It also examines collaborations with different countries worldwide. The authorship pattern, document types involved and active Indian institutions co-coordinating research in this subject area have also been studied. Bradford law of scattering was employed to identify the core journals and Lotka’s law was employed to study the authors’ productivity pattern.

TL;DR: This paper proposes a multilayered conceptual framework wherein the levels of meaning, relationships and extension and intension are each controlled as individual parameters, rather than in a single switching language.
Abstract: ieved. In order to facilitate subject access interoperability a mechanism must be built that allows the different controlled vocabularies to communicate meaning, relationships, and levels of extension and intension so that different user groups using different controlled vocabularies could access collections across the network. Switching languages, the tools of controlled vocabulary compatibility, consist of a single layer that does not allow for a flexible control of the semantic levels of meaning, relationships, and extension or intension. This paper proposes a multilayered conceptual framework wherein the levels of meaning, relationships and extension and intensio each controlled as individual parameters, rather than in a single switching langua

TL;DR: According to literature, web system architecture based on the faceted analysis appears to be highly common even in the big data settings, and more theoretical and empirical work is necessary to firm up this standpoint.
Abstract: Over the last years, information growth has been the source of a large volume and variety of data, therefore new processes to represent, organize, seek and retrieve the information are needed. The background theory that supports the big data settings is diverse, however, one theory has deserved special attention in the literature, not only as a model for structuring data but also for locating information: the faceted theory. In this paper, a brief review of the literature about big data and faceted theory is presented. According to literature, web system architecture based on the faceted analysis appears to be highly common even in the big data settings. Regarding description, navigation, seek and search, and retrieval of the information, the authors write up the faceted theory, methods, and models in a digital environment. Nevertheless, more theoretical and empirical work is necessary to firm up this standpoint. Keywords: Faceted theory, Big Data, Information seeking, Information retrieval, Web system architecture

TL;DR: App approaches are provided that support the maintenance of hierarchical knowledge organization systems, like thesauri, classifications, or taxonomies, by making information about the usage of KOS concepts available to the maintainer by means of the ICE-Map Visualization.
Abstract: Knowledge Organization Systems (KOS) are typically used as background knowledge
for document indexing in information retrieval. They have to be maintained
and adapted constantly to reflect changes in the domain and the terminology. In
this thesis, approaches are provided that support the maintenance of hierarchical
knowledge organization systems, like thesauri, classifications, or taxonomies, by
making information about the usage of KOS concepts available to the maintainer.
The central contribution is the ICE-Map Visualization, a treemap-based visualization
on top of a generalized statistical framework that is able to visualize almost
arbitrary usage information. The proper selection of an existing KOS for available
documents and the evaluation of a KOS for different indexing techniques by means
of the ICE-Map Visualization is demonstrated.
For the creation of a new KOS, an approach based on crowdsourcing is presented
that uses feedback from Amazon Mechanical Turk to relate terms hierarchically.
The extension of an existing KOS with new terms derived from the documents
to be indexed is performed with a machine-learning approach that relates
the terms to existing concepts in the hierarchy. The features are derived from text
snippets in the result list of a web search engine. For the splitting of overpopulated
concepts into new subconcepts, an interactive clustering approach is presented that
is able to propose names for the new subconcepts.
The implementation of a framework is described that integrates all approaches
of this thesis and contains the reference implementation of the ICE-Map Visualization.
It is extendable and supports the implementation of evaluation methods
that build on other evaluations. Additionally, it supports the visualization of the
results and the implementation of new visualizations. An important building block
for practical applications is the simple linguistic indexer that is presented as minor
contribution. It is knowledge-poor and works without any training.
This thesis applies computer science approaches in the domain of information
science. The introduction describes the foundations in information science; in the
conclusion, the focus is set on the relevance for practical applications, especially
regarding the handling of different qualities of KOSs due to automatic and semiautomatic
maintenance.
