  • Oracle system performance inefficiencies often go undetected for months or even years--even under intense scrutiny--because traditional Oracle performance analysis methods and tools are fundamentally flawed. They're unreliable and inefficient. Oracle DBAs and developers are all too familiar with the outlay of time and resources, blown budgets, missed deadlines, and marginally effective performance fiddling that is commonplace with traditional methods of Oracle performance tuning.

  • Poorly performing enterprise applications are the weakest links in a corporation's management chain, causing delays and disruptions of critical business functions. This groundbreaking book frames enterprise application performance engineering not as an art but as applied science built on model-based methodological foundation. The book introduces queuing models of enterprise application that visualize, demystify, explain, and solve system performance issues.

  • In this paper we examine how the differences in modelling between different data driven systems performing the same NLP task can be exploited to yield a higher accuracy than the best individual system. We do this by means of an experiment involving the task of morpho-syntactic wordclass tagging. Four well-known tagger generators (Hidden Markov Model, Memory-Based, Transformation Rules and Maximum Entropy) are trained on the same corpus data. After comparison, their outputs are combined using several voting strategies and second stage classifiers. ...

  • The importance of the new textual genres such as blogs or forum entries is growing in parallel with the evolution of the Social Web. This paper presents two corpora of blog posts in English and in Spanish, annotated according to the EmotiBlog annotation scheme. Furthermore, we created 20 factual and opinionated questions for each language and also the Gold Standard for their answers in the corpus. The purpose of our work is to study the challenges involved in a mixed fact and opinion question answering setting by comparing the performance of two Question Answering (QA) systems as far as...

  • We address the task of automatically predicting if summarization system performance will be good or bad based on features derived directly from either single- or multi-document inputs. Our labelled corpus for the task is composed of data from large scale evaluations completed over the span of several years. The variation of data between years allows for a comprehensive analysis of the robustness of features, but poses a challenge for building a combined corpus which can be used for training and testing.

  • A distributed file system stores files in several nodes of a distributed system, so a process and a file used by it might be in different nodes of a system. Performance and reliability of a distributed file system are determined by the manner in which it organizes access to a required file. This chapter discusses different methods of organizing access to files and directories located in various nodes of a system, and techniques such as file caching and stateless file servers that are used to ensure good performance and reliability, respectively.

  • From the very beginning of the transition from the traditional purchasing system reviews to the redesigned assessment approach that replaced them, it was understood that further refinement and continuous improvement was planned. Consistent with that long-term strategy, and building on the originally redesigned federal purchasing assessments, the business system assessment models of the PEAmembers have evolved to be more aligned with the Balanced Scorecard (BSC) approach to performance measurement and management, which is currently in use by many “world class” private corporations.
