This article contributes to the quality control of digitization workflows, and to the exploitation of historical document collections, by demonstrating the utility of serendipitous exploration (as opposed to targeted searches) through the use of Document Towers, a visual representation of the physical structure of documents as architectural models. The Document Towers are evaluated via a qualitative case study on historical Swiss newspapers, a thought experiment comparing them to alternative solutions, a diagrammatic visual and numeric assessment of exploratory tasks, and several quantitative and empirical usability measurements and psychometric surveys. The experiments confirmed that both serendipitous exploration and the Document Towers visualization are objectively well-suited for the quality control and exploration of digital documents. A significant disparity in subjective usability was observed between librarians and academics, who rated the visualization concept below and above average, respectively. Other findings included the redefinition of quality control as a tool of knowledge and dialogue among stakeholders in information systems; a generic diagrammatic instrument for evaluating the outcomes of explorations; demonstrating how the adoption of novel information technology may benefit from adaptation to individual psychologies and socio-professional contexts; and, unexpectedly, novel historical insights into Swiss map-making, newspaper history, and censorship.

Testo completoAbstract (sommario):
In the information retrieval system, relevance manifestation is pivotal and regularly based on document-term statistics, i.e., term frequency (tf), inverse document frequency (idf), etc. Query term proximity (QTP) within matched documents is mostly under-explored. In this article, a novel information retrieval framework is proposed to promote the documents among all relevant retrieved ones. The relevance estimation is a weighted combination of document statistics and query term statistics, and term-term proximity is simply aggregates of diverse user preferences aspects in query formation, thus adapted into the framework with conventional relevance measures. Intuitively, QTP is exploited to promote the documents for balanced exploitation-exploration, and eventually navigate a search towards goals. The evaluation asserts the usability of QTP measures to balance several seeking tradeoffs, e.g., relevance, novelty, result diversification (coverage, topicality), and overall retrieval. The assessment of user search trails indicates significant growth in a learning outcome (due to novelty).

In the era of internet communication, many electronic documents are spread and flow on the platform of website in every splits of seconds. The research interest for the process of knowledge discovery is changed from the traditional data to online data such as online news document classification. Most percentage of the online data is text document and therefore the optimization of multi-class document classification is becoming a challenge for today society. Traditional search policy for feature selection process is degrading with exhaustive search for complex feature in document classification. Therefore, meta-heuristic based computational search is also becoming good solution to overcome the problem of exhaustive search with exploitation process. The search policy of computational algorithm can provide the global optimal solution with random search approach on both exploitation and exploration process, and the selected search results of feature subsets can support the optimal classification results.

<p>Most applications, such as Information Retrieval and Natural Language Processing (NLP), utilize document clustering to improve their analysis. The document consists of various features that are utilized to determine the similar and dissimilar documents. However, the traditional techniques consume high computation difficulties and convergence problems while analyzing high-dimensional data. The research difficulties are addressed with the help of Bacterial Foraging and Rough Set Analysis (BF-RSA). This study uses the TF-IDF features for analyzing similar documents. The extracted features are explored using the Bacterial Foraging Optimization (BFO) approach that uses the exploration and exploitation characteristics to improve the overall clustering quality. The collected documents are analyzed using a roughest approach that generates the discernible matrix which helps to identify similar and dissimilar features. Then bacterial foraging method computes the fitness value according to their behavior to identify the optimal solution. The selected feature set is further analyzed in the roughest approximation condition to minimize the uncertainty and interpretability issues. The effective integration of bacteria foraging and rough set approach maximizes the feature selection accuracy and improves the clustering accuracy (97.05%) with minimum convergence speed (0.063 s).</p>

Testo completoAbstract (sommario):
Purpose The purpose of this paper is to investigate the historical contributions of complex innovations (both creative and tactical components) in a formative period in a major Australian department store, David Jones Ltd. Design/methodology/approach The study uses a context-specific lens to examine complex retail innovation. The study adopts a longitudinal design with the focus on a single firm, which met the inclusion criteria. Data collection was predominately from company archival materials and publicly available documents, including newspapers. Findings An in-depth analysis of two complex innovations demonstrates the retailer’s successful management of both marketing exploration (innovation) and marketing exploitation of that innovation. Effective marketing requires operational, tactical marketing exploitation to dovetail marketing exploration. Research limitations/implications The study is limited to one successful department store. Notwithstanding, there are expectations that the lessons extend to many other retailing organizations. Practical implications The practical relevance is clear, with the emphasis on retail innovation (and especially complex innovation) as a basis for both surviving and thriving in an ever-changing marketing environment. Originality/value The use of a complex innovation approach is a novel way of examining marketing history. The study concludes that both marketing exploration and marketing exploitation are essential for retail longevity.

The paper provides an overview of the main stages and types of exploration works for solid minerals according to the current regulatory documents of the Ministry of Natural Resources and Ecology of the Russian Federation, and also considers the features of accounting for these works in conformity with the requirements of RAS 24/2011 “Accounting for the costs on exploitation of natural resources”, IFRS 6 “Exploration and Assessment of Mineral Reserves” and IAS 36 “Asset Impairment”. According to the results of a comparative analysis of RAS and IFRS, assessment of the methods for reflecting exploration work in the accounting of mining companies, an analysis of their impact on management decisions by stakeholders is carried out. The theoretical and practical significance of the study is to justify the need to develop an alternative methodology for accounting and presentation of accounting information on the results of exploration, based on a phased increase in the reliability of knowledge about subsoil areas. The study is primarily interest to government agencies for improving the legislative regulation of accounting, credit institutions and mining companies in conducting investment analysis of customers and partners.

Purpose In highly dynamic industries, business processes require exploitation, i.e. activities that are associated with an increase in productivity through automation, standardization, integrated architectures, and the usage of existing IT resources. As a complementary capability, exploration is needed, i.e. the ability to flexibly implement new and innovative IT resources (Lee et al., 2015). The purpose of this paper is to use the concept of ambidexterity, which is researched intensively outside the domain of business processes (e.g. Gibson and Birkinshaw, 2004; Tang and Rai, 2014), to address this paradoxical trade-off within business processes. Design/methodology/approach The paper follows a qualitative approach. A multiple case study comprising 11 interviews and additional document analysis in six organizations is conducted in the German energy sector to examine the proposed framework. Findings This paper shows the importance of balancing exploitative and explorative business process IT (BPIT) capabilities. The process-theoretical outcome of this study is the BPIT Capability Framework that provides explanation for the interaction between exploitation and exploration. Research limitations/implications This study contributes to the understanding of how to build ambidextrous BPIT capabilities by explaining the underlying mechanisms for feedback loops that occur in cases of imbalance. The scope of the conducted study presents a limitation and thus future research is encouraged to further validate the findings of this paper. Originality/value By drilling down to the process level, this paper addresses the gaps that limited empirical studies have in business process management research (Recker and Mendling, 2015) and the focus on business processes that is lacking from the literature on organizational IT management (Gregory et al., 2015).

The increased adoption of unmanned aerial vehicles (UAVs) may improve the productivity and cost-effectiveness of remote sensing in the mining industry. This review's objective is to enable stakeholders to identify possible application adoption, improvement, and innovation opportunities. The review merges a building block strategy and practical screening criteria to identify possible avenues of research to answer the review questions. After the screening process, 72 documents were included in the review. Papers were classified into four categories: exploration, development, exploitation, and reclamation. Fifteen applications were identified, the majority of which were in the exploration phase. The most often researched applications were topographic surveys, reclamation monitoring, and slope management. From the two UAV types identified, multi-rotor vehicles were the most favoured for all applications. From the eight remote sensing techniques identified, photogrammetry was the one most often used. Other techniques were limited because of complexity, cost, or the incompatibility of sensors and UAVs. The review was limited to published papers in academic journals. Future studies could aim to include empirical data on the latest UAV applications used in the mining industry.

Abstract: Purpose: The purpose of this work is to explore The Trial of Dedan Kimathi through the lenses of revolutionary aesthetics and class stratification as a kind of socio-literary participation. The book's exploration of the notion of revolution delves deeply into topics of tyranny, exploitation, and poverty. Numerous consequences emerged from the examination of the selected text. Research methodology: Theoretical Framework: Marxist literary theory guided the analysis of the study. Results: This research documents European aggression, economic exploitation of Africans, taxes and forced labor, the degradation of people's humanity, a decrease in human capital, the depths of hunger and poverty, and Africans' reaction and resistance to these terrible conditions. In order to come up with a long-term solution, we need to understand and agree that Africans have been oppressed and treated cruelly in the past. Limitations: The study is limited to the play The Trial of Dedan Kimathi. Contribution: The Marxist philosophy has been used as a weapon of change in order to bring about revolutions. Through the medium of theater, people may be entertained, educated, and made more aware. Keywords: 1. Africa 2. Class 3. Kimathi 4. Marxism 5. Revolution

Every human culture has reflected the Moon’s influence in its cosmology, spirituality, science, creative and social life. For these reasons, the exploration and use of the Moon should be done thoughtfully and carefully, and possible resource extraction should not harm the Earth's only satellite and its environment as a whole. The adoption by some States of national legislation affecting the commercial exploitation of space resources, as well as the resumption of lunar programs by several leading spacefaring nations at a time, prompt the need for legal regulation in this area. However, to develop a detailed international legal regime for lunar exploration, the efforts of the States parties to the UN COPUOS alone are not sufficient since in practice other actors in international relations, including the so-called epistemic communities representing various types of non-governmental organizations, are also active participants in space activities. Such communities offer their own vision of the international legal regulation of relations arising in the framework of the exploration and use of the Moon basing on the norms of international space law and involving active participation of non-governmental legal entities, considering the interests of present and future generations, as well as of emerging space nations. The study presents a comprehensive analysis of the influence of epistemic communities on the development of the future international legal regime for lunar exploration. The authors consistently review the activities of non-governmental organizations within the UN COPUOS since its formation. Special attention is paid to the contribution of such communities to the progressive development of international space law and its codification, including the legal nature of the documents developed by such communities. The study concludes with a comprehensive international legal assessment of the activities of the epistemic communities.
