In this paper, we present a topic discovery system aimed to reveal the implicit knowledge present in news streams. This knowledge is expressed as a hierarchy of topic/subtopics, where each topic contains the set of documents that are related to it and a summary extracted from these documents. Summaries so built are useful to browse and select topics of interest from the generated hierarchies. Our proposal consists of a new incremental hierarchical clustering algorithm, which combines both partitional and agglomerative approaches, taking the main benefits from them. Finally, a new summarization method based on Testor Theory has been proposed to build the topic summaries. Experimental results in the TDT2 collection demonstrate its usefulness and effectiveness not only as a topic detection system, but also as a classification and summarization tool. 相似文献

This article analyses the review, acceptance and publication dates of a sample of 21,890 articles from 326 Ibero-American scientific journals from all subject areas and countries included in the Latindex Catalogue 2.0 and published between 2018 and 2020 (freely available as an open access dataset). The aim is to discover evaluation and publication times. The evaluation process takes a median of 110 days, the publication process, a median of 82 days, and the whole process, a median of 224 days. Statistical differences are found according to periodicity, subject areas, countries, existence of a printed version and article type (Call for Papers or General articles). From the data we find that the delay in publication is longer than publishers themselves report to the DOAJ. STEM areas present the most similarity in publication patterns, having a higher number of evaluation days (Ed) than publication days (Pd); Arts and Humanities present the opposite pattern, with a higher Pd than Ed. In the case of Social Sciences, the times are similar. General articles and Call for Papers articles differ in terms of Ed, but not Pd, indicating that Call for Papers revisions are faster. 相似文献

Analyzing the impact of knowledge management on CRM success: The mediating effects of organizational factors 总被引：1，自引：0，他引：1

Customer relationship management (CRM) and knowledge management (KM) have become key strategic tool for all companies, especially in the current competitive environment. Moreover, customer knowledge is an important issue for CRM implementation. Reviewing the literature, we found many studies that analyze the crucial role played by KM initiatives as determinants of the success of CRM. Moreover, we found also diverse studies that show high rates of failure when implementing that strategy, so there is still no integrated conceptual framework to guide companies to their successful implementation. In this paper, with data of 153 Spanish hotels, we examine the relationships between KM and CRM success using a structural equation model. The main contribution is that having knowledge management capabilities is not sufficient for the success of CRM, but there are other factors to consider. In particular, organizational factors indeed impact CRM success and they appear to be intermediaries of the impact of other factors (KM capabilities/technological/customer orientation factors) in the success of CRM (in financial and marketing terms). 相似文献

The article provides an alternative theoretical framework for evaluating contemporary issues facing education, specifically vocational education and training (VET) in Europe. In order to accomplish this, it draws on the theoretical insights of the capability approach in the work of Amartya Sen; the concept of vulnerability as intrinsic to every human being, established by Fineman and Grear; and the concept of oppression advanced by Iris Marion Young. By developing the core concepts of each of these theories, the paper presents a human-based evaluative tool for education and argues that a fundamental misconception has arisen as to the purpose of post-compulsory education, a misconception generated by the wholesale application of the language of skills and productivity to the field of education, thus relinquishing its role to purely economic interests. The social justice framework presented herein aims to present a possible alternative approach to discuss and evaluate VET, in which humanistic concepts such as the recognition of human vulnerability and agency are central to the debate. 相似文献

Purpose
The aim of the present study was to determine, through colorimetric analysis, whether school textbooks for children aged 5 to 7 years contained tasks requiring normal colour vision discrimination for their resolution. In addition, the performance of a group of observers with diverse colour vision deficiencies was evaluated while conducting the tasks under analysis.Results
Textbooks of mathematics were found to include 10% of tasks which, to an observer with colour vision deficiency, would be very difficult or impossible to solve. The level of difficulty of each task was influenced by the type and degree of colour vision deficiency and by the actual ambient illumination under which it was observed.Conclusions
Some school textbooks need to be redesigned through an alternative use of colours and textures to take into consideration colour vision deficiencies. In view of the present findings, many Spanish editorial boards have committed to undertake these changes. 相似文献7.

A team of performance consultants looks closely at the operations of a cable services provider to identify existing performance gaps, barriers to performance, declining customer satisfaction ratings, and increased call volumes. The team used performance‐centered design (PCD) solutions in order to overcome technical support challenges through increased first‐call resolution. This article summarizes the root cause analysis, process, and the application of PCD solutions to close performance gaps, along with lessons learned from this case study. 相似文献
