系统日志文件记录着系统中特定事件的相关活动信息,系统日志文件是计算机取证最重要的信息来源。Windows系统对日志文件进行保护不允许对日志文件进行修改,只允许对日志进行清空操作以保证日志文件的完整性。详尽描述了日志文件的格式,在此基础上找到了手工修改和删除日志记录的方法,并在Windows XP SP3下得到了验证。 相似文献

To obtain high performances, previous works on FAQ retrieval used high-level knowledge bases or handcrafted rules. However, it is a time and effort consuming job to construct these knowledge bases and rules whenever application domains are changed. To overcome this problem, we propose a high-performance FAQ retrieval system only using users’ query logs as knowledge sources. During indexing time, the proposed system efficiently clusters users’ query logs using classification techniques based on latent semantic analysis. During retrieval time, the proposed system smoothes FAQs using the query log clusters. In the experiment, the proposed system outperformed the conventional information retrieval systems in FAQ retrieval. Based on various experiments, we found that the proposed system could alleviate critical lexical disagreement problems in short document retrieval. In addition, we believe that the proposed system is more practical and reliable than the previous FAQ retrieval systems because it uses only data-driven methods without high-level knowledge sources. 相似文献

Several studies of Web server workloads have hypothesized that these workloads are self-similar. The explanation commonly advanced for this phenomenon is that the distribution of Web server requests may be heavy-tailed. However, there is another possible explanation: self-similarity can also arise from deterministic, chaotic processes. To our knowledge, this possibility has not previously been investigated, and so existing studies on Web workloads lack an adequate comparison against this alternative. We conduct an empirical study of workloads from two different Web sites: one public university, and one private company, using the largest datasets that have been described in the literature. Our study employs methods from nonlinear time series analysis to search for chaotic behavior in the web logs of these two sites. While we do find that the deterministic components (i.e. the well-known “weekend effect”) are significant components in these time series, we do not find evidence of chaotic behavior. Predictive modeling experiments contrasting heavy-tailed with deterministic models showed that both approaches were equally effective in modeling our datasets. 相似文献

The anonymization of query logs is an important process that needs to be performed prior to the publication of such sensitive data. This ensures the anonymity of the users in the logs, a problem that has been already found in released logs from well known companies. This paper presents the anonymization of query logs using microaggregation. Our proposal ensures the k-anonymity of the users in the query log, while preserving its utility. We provide the evaluation of our proposal in real query logs, showing the privacy and utility achieved, as well as providing estimations for the use of such data in data mining processes based on clustering. 相似文献

During the mid-1960s, Peter R. Vail at Exxon Production Research Co. led a group working with the new, greatly improved generation of multifold seismic reflection data being shot along the continental margins of the world. The work of this group, inspired by Vail, brought the worlds of stratigraphy and seismic interpretation together in developing the original concepts of seismic stratigraphy.Later these concepts were applied by Vail and his co-workers to well logs, cores, and outcrops, broadening seismic stratigraphy into what is known today as sequence stratigraphy. Using these data the group was documenting and interpreting large-scale, basin-wide depositional patterns, stratal configurations, and unconformities in basins around the world. They proposed a chronology of global sea-level fluctuation as a framework for global correlation, resulting in a world sea-level curve. This further led to a new eustatic sea-level model. The results of these studies impacted on many scientific disciplines, but its implications for the petroleum industry have been extensive.A review of 19th- and 20th-Century stratigraphic thought on unconformities and unconformity-bounded stratal units suggests that Peter Vail followed in the footsteps of the eminent stratigraphers Charles Lyell, T. C. Chamberlain, and L. L. Sloss, his former teacher.For his contributions to sequence stratigraphy and the world sea-level curve, Peter R. Vail was awarded the 2005 Benjamin Franklin Medal in Earth and Environmental Science. 相似文献

Abstract The developing countries, although not homogeneous, share a growing recognition of the importance of information technology for fostering the development process. Rapid advancements in computer and telecommunications technologies offer new opportunities for improved resource management and for the successful employment of these tools in rural areas. Although developing nations have responded enthusiastically to the advantages of modem information technology, they are equally cognizant of the negative impact that reliance on foreign technology and services may have. As a result, developing countries are taking a number of actions—at the national, regional, and international levels—to ensure their active participation in the emerging Information Age. 相似文献

Recent years have seen a profound change in how most users interact with search engines: the majority of search requests now come from mobile devices, which are used in a number of distracting contexts. This use of mobile devices in various situational contexts away from a desk presents a range of novel challenges for users and, consequently, possibilities for interface improvements. However, there is at present a lack of work that evaluates interaction in such contexts to understand what effects context and mobility have on behaviour and errors and, ultimately, users’ search performance.Through a controlled study, in which we simulate walking conditions on a treadmill and obstacle course, we use a combination of interaction logs and multiple video streams to capture interaction behaviour as participants (n = 24) complete simple search tasks. Using a bespoke tagging tool to analyse these recordings, we investigate how situational context and distractions impact user behaviour and performance, contrasting this with users in a baseline, seated condition. Our findings provide insights into the issues these common contexts cause, how users adapt and how such interfaces could be improved. 相似文献
