Emerging paradigms of attack challenge enterprise cybersecurity with sophisticated custom-built tools, unpredictable patterns of exploitation, and an increasing ability to adapt to cyber defenses. As a result, organizations continue to experience incidents and suffer losses. The responsibility to respond to cybersecurity incidents lies with the incident response (IR) function. We argue that (1) organizations must develop ‘agility’ in their IR process to respond swiftly and efficiently to sophisticated and potent cyber threats, and (2) Real-time analytics (RTA) gives organizations a unique opportunity to drive their IR process in an agile manner by detecting cybersecurity incidents quickly and responding to them proactively. To better understand how organizations can use RTA to enable IR agility, we analyzed in-depth data from twenty expert interviews using a contingent resource-based view. The results informed a framework explaining how organizations enable agile characteristics (swiftness, flexibility, and innovation) in the IR process using the key features of the RTA capability (complex event processing, decision automation, and on-demand and continuous data analysis) to detect and respond to cybersecurity incidents as-they-occur which, in turn, improves their overall enterprise cybersecurity performance. 相似文献

The proliferation of sports science and technological innovation within performance settings has precipitated the generation of increasing volumes of data to aid athletes. Copious data production has also perpetuated the privileging of scientific information, and a ‘thirst’ for ‘more data’ as an unproblematic ‘truth’. Of significance is not merely the use of technology for the production of data-for-data's sake, or the utility of data for a greater cause (e.g. the good of the team), but the quest for personalised data for individual athletes to be analysed, and reflected upon ad nauseam. Furthering scholarship on disciplining bodies, we argue that increased technological consumption, and the related excessive quantification of athletes’ bodies via data production, adds further insecurity into performance sports work. Finally, attention is given to the cultural step-change new techno-dispositions may now present. 相似文献

Firms are increasingly relying on business insights obtained by deploying data analytics. Analytics-driven business decisions have thus taken a strategic imperative role for the competitive advantage of a firm to endure. The extent and effectiveness through which business firms can actually derive benefits by deploying big data-based practices requires deep analysis and calls for extensive research. This study extends the big data analytics capability (BDAC) model by examining the mediatory effects of organizational culture (CL) between internal analytical knowledge (KN) and BDAC, as well as the mediating effects of BDAC between CL and firm performance. The findings bring into focus that CL plays the role of complementary mediation between BDAC and KN to positively impact firm performance (FP); BDAC also plays a similar mediatory role between CL and the performance of a firm. 相似文献

Negation recognition in medical narrative reports 总被引:1,自引:0,他引:1
Substantial medical data, such as discharge summaries and operative reports are stored in electronic textual form. Databases
containing free-text clinical narratives reports often need to be retrieved to find relevant information for clinical and
research purposes. The context of negation, a negative finding, is of special importance, since many of the most frequently
described findings are such. When searching free-text narratives for patients with a certain medical condition, if negation
is not taken into account, many of the documents retrieved will be irrelevant. Hence, negation is a major source of poor precision
in medical information retrieval systems. Previous research has shown that negated findings may be difficult to identify if
the words implying negations (negation signals) are more than a few words away from them. We present a new pattern learning
method for automatic identification of negative context in clinical narratives reports. We compare the new algorithm to previous
methods proposed for the same task, and show its advantages: accuracy improvement compared to other machine learning methods,
and much faster than manual knowledge engineering techniques with matching accuracy. The new algorithm can be applied also
to further context identification and information extraction tasks.

A compressed full-text self-index for a text T, of size u, is a data structure used to search for patterns P, of size m, in T, that requires reduced space, i.e. space that depends on the empirical entropy (H
k
or H
0) of T, and is, furthermore, able to reproduce any substring of T. In this paper we present a new compressed self-index able to locate the occurrences of P in O((m + occ)log u) time, where occ is the number of occurrences. The fundamental improvement over previous LZ78 based indexes is the reduction of the search
time dependency on m from O(m
2) to O(m). To achieve this result we point out the main obstacle to linear time algorithms based on LZ78 data compression and expose
and explore the nature of a recurrent structure in LZ-indexes, the suffix tree. We show that our method is very competitive in practice by comparing it against other state of the art compressed
indexes.

AbstractInspired by Gao’s text analysis of communication studies faculty, this study looks at the trends from 176 faculty publications from the criminal justice department at the University of Nevada, Reno. Criminal justice faculty publications are missing from library science text analysis literature. This study uses Voyant and NVivo 12 to analyze words and phrases from titles and abstracts to identify research interests. Voyant itself was found to be sufficient and identified specific research trends such as organizational commitment, amber alerts, and death qualification. This study can assist liaison librarians in selecting between these two tools based on their needs. 相似文献

易读性是教材编写中阅读材料选择的重要标准之一,易读性公式虽有诸多缺陷,仍是目前最客观、最有效的易读性测量方式。为了检验目前高职英语教材的易读性现状,为高职英语教材的编写提供信息和为高职英语教材的使用者提供选择的标准,本文就文本总体统计特征和易读性指数两方面调查了三种有代表性的高职英语教材,发现所调查的高职英语教材在易读性的总体控制方面把握得不错,但在细节方面尚有诸多需要完善的地方,同时发现了几个问题急待进一步的研究。 相似文献
