Chapter 3, Systems of measurement and weight, reviews weights and measures. It introduces the metric system as well as apothecary and household systems. Time and temperature conversions are included. Special attention is given to conversion factors, and the procedures for ratio proportion, fraction proportion, and dimensional analysis methods are introduced as building blocks for later chapters.

• ### Đề tài " Metric attractors for smooth unimodal maps "

We classify the measure theoretic attractors of general C 3 unimodal maps with quadratic critical points. The main ingredient is the decay of geometry. 1. Introduction 1.1. Statement of results. The study of measure theoretical attractors occupied a central position in the theory of smooth dynamical systems in the 1990s. Recall that a forward invariant compact set A is called a (minimal) metric attractor for some dynamics if the basin of attraction B(A) := {x : ω(x) ⊂ A} of A has positive Lebesgue measure and B(A ) has Lebesgue measure zero for every forward invariant compact set...

• ### Báo cáo khoa học: "QARLA:A Framework for the Evaluation of Text Summarization Systems"

This paper presents a probabilistic framework, QARLA, for the evaluation of text summarisation systems. The input of the framework is a set of manual (reference) summaries, a set of baseline (automatic) summaries and a set of similarity metrics between summaries. It provides i) a measure to evaluate the quality of any set of similarity metrics, ii) a measure to evaluate the quality of a summary using an optimal set of similarity metrics, and iii) a measure to evaluate whether the set of baseline summaries is reliable or may produce biased results. ...

• ### Assessing the National Health Information System An Assessment Tool VERSION 4.00

The Health Metrics Network (HMN) was launched in 2005 to help countries and other partners improve global health by strengthening the systems that generate health-related information for evidence-based decision-making. HMN is the first global health partnership that focuses on two core requirements of health system strengthening in low and low-middle income countries. First, the need to enhance entire health information and statistical systems, rather than focus only upon specific diseases.

• ### Báo cáo khoa học: "a Precision-Order-Recall MT Evaluation Metric for Tuning"

Many machine translation (MT) evaluation metrics have been shown to correlate better with human judgment than BLEU. In principle, tuning on these metrics should yield better systems than tuning on BLEU. However, due to issues such as speed, requirements for linguistic resources, and optimization difficulty, they have not been widely adopted for tuning.

• ### Báo cáo khoa học: "An inexpensive, high-accuracy, semi-automatic metric for evaluating translation utility via semantic frames"

We introduce a novel semi-automated metric, MEANT, that assesses translation utility by matching semantic role fillers, producing scores that correlate with human judgment as well as HTER but at much lower labor cost. As machine translation systems improve in lexical choice and fluency, the shortcomings of widespread n-gram based, fluency-oriented MT evaluation metrics such as BLEU, which fail to properly evaluate adequacy, become more apparent.

• ### Báo cáo khoa học: "Using Crowdsourcing to Improve the Evaluation of Grammatical Error Detection Systems"

Despite the rising interest in developing grammatical error detection systems for non-native speakers of English, progress in the ﬁeld has been hampered by a lack of informative metrics and an inability to directly compare the performance of systems developed by different researchers. In this paper we address these problems by presenting two evaluation methodologies, both based on a novel use of crowdsourcing.

• ### Báo cáo khoa học: "Simulating the Behaviour of Older versus Younger Users when Interacting with Spoken Dialogue Systems"

In this paper we build user simulations of older and younger adults using a corpus of interactions with a Wizard-of-Oz appointment scheduling system. We measure the quality of these models with standard metrics proposed in the literature. Our results agree with predictions based on statistical analysis of the corpus and previous ﬁndings about the diversity of older people’s behaviour.

• ### Báo cáo khoa học: "The Utility of a Graphical Representation of Discourse Structure in Spoken Dialogue Systems"

In this paper we explore the utility of the Navigation Map (NM), a graphical representation of the discourse structure. We run a user study to investigate if users perceive the NM as helpful in a tutoring spoken dialogue system. From the users’ perspective, our results show that the NM presence allows them to better identify and follow the tutoring plan and to better integrate the instruction. It was also easier for users to concentrate and to learn from the system if the NM was present. Our preliminary analysis on objective metrics further strengthens these findings. ...

• ### Báo cáo khoa học: "Quantitative and Qualitative Evaluation of Darpa Communicator Spoken Dialogue Systems"

This paper describes the application of the PARADISE evaluation framework to the corpus of 662 human-computer dialogues collected in the June 2000 Darpa Communicator data collection. We describe results based on the standard logﬁle metrics as well as results based on additional qualitative metrics derived using the DATE dialogue act tagging scheme. We show that performance models derived via using the standard metrics can account for 37% of the variance in user satisfaction, and that the addition of DATE metrics improved the models by an absolute 5%. ...

• ### Báo cáo khoa học: "Designing a Task-Based Evaluation Method ology for a Spoken Machine Translation System"

In this paper, I discuss issues pertinent to the design of a task-based evaluation methodology for a spoken machine translation (MT) system processing human to human communication rather than human to machine communication. I claim that system mediated human to human communication requires new evaluation criteria and metrics based on goal complexity and the speaker's prioritization of goals. ystem

• ### Báo cáo khoa học: "Evaluating language understanding accuracy with respect to objective outcomes in a dialogue system"

It is not always clear how the differences in intrinsic evaluation metrics for a parser or classiﬁer will affect the performance of the system that uses it. We investigate the relationship between the intrinsic evaluation scores of an interpretation component in a tutorial dialogue system and the learning outcomes in an experiment with human users. Following the PARADISE methodology, we use multiple linear regression to build predictive models of learning gain, an important objective outcome metric in tutorial dialogue.

• ### Báo cáo khoa học: "Combining Coherence Models and Machine Translation Evaluation Metrics for Summarization Evaluation"

An ideal summarization system should produce summaries that have high content coverage and linguistic quality. Many state-ofthe-art summarization systems focus on content coverage by extracting content-dense sentences from source articles. A current research focus is to process these sentences so that they read ﬂuently as a whole.

• ### Báo cáo khoa học: "A Web-based Evaluation Framework for Spatial Instruction-Giving Systems"

We demonstrate a web-based environment for development and testing of different pedestrian route instruction-giving systems. The environment contains a City Model, a TTS interface, a game-world, and a user GUI including a simulated street-view. We describe the environment and components, the metrics that can be used for the evaluation of pedestrian route instruction-giving systems, and the shared challenge which is being organised using this environment.

• ### Báo cáo khoa học: "Comparing Automatic and Human Evaluation of NLG Systems"

We consider the evaluation problem in Natural Language Generation (NLG) and present results for evaluating several NLG systems with similar functionality, including a knowledge-based generator and several statistical systems. We compare evaluation results for these systems by human domain experts, human non-experts, and several automatic evaluation metrics, including NIST, BLEU, and ROUGE. We ﬁnd that NIST scores correlate best ( 0.8) with human judgments, but that all automatic metrics we examined are biased in favour of generators that select on the basis of frequency alone. ...

• ### Electrical Engineering - Know It All

The system of units used in engineering and science is the Système International d’Unités (International system of units), usually abbreviated to SI units, and is based on the metric system. This was introduced in 1960 and is now adopted by the majority of countries as the offi cial system of measurement.
