    Automatic Extraction of Commonsense LocatedNear Knowledge

    Full text link
    LocatedNear relation is a kind of commonsense knowledge describing two physical objects that are typically found near each other in real life. In this paper, we study how to automatically extract such relationship through a sentence-level relation classifier and aggregating the scores of entity pairs from a large corpus. Also, we release two benchmark datasets for evaluation and future research.Comment: Accepted by ACL 2018. A preliminary version is presented on AKBC@NIPS'1

    N-Jettiness Subtractions for ggHgg\to H at Subleading Power

    NN-jettiness subtractions provide a general approach for performing fully-differential next-to-next-to-leading order (NNLO) calculations. Since they are based on the physical resolution variable NN-jettiness, TN\mathcal{T}_N, subleading power corrections in τ=TN/Q\tau=\mathcal{T}_N/Q, with QQ a hard interaction scale, can also be systematically computed. We study the structure of power corrections for 00-jettiness, T0\mathcal{T}_0, for the ggHgg\to H process. Using the soft-collinear effective theory we analytically compute the leading power corrections αsτlnτ\alpha_s \tau \ln\tau and αs2τln3τ\alpha_s^2 \tau \ln^3\tau (finding partial agreement with a previous result in the literature), and perform a detailed numerical study of the power corrections in the gggg, gqgq, and qqˉq\bar q channels. This includes a numerical extraction of the αsτ\alpha_s\tau and αs2τln2τ\alpha_s^2 \tau \ln^2\tau corrections, and a study of the dependence on the T0\mathcal{T}_0 definition. Including such power suppressed logarithms significantly reduces the size of missing power corrections, and hence improves the numerical efficiency of the subtraction method. Having a more detailed understanding of the power corrections for both qqˉq\bar q and gggg initiated processes also provides insight into their universality, and hence their behavior in more complicated processes where they have not yet been analytically calculated.Comment: 16 pages, 12 figure

    Technical Target Setting in QFD for Web Service Systems using an Artificial Neural Network

    Get PDF
    There are at least two challenges with quality management of service-oriented architecture based web service systems: 1) how to link its technical capabilities with customer\u27s needs explicitly to satisfy customers\u27 functional and nonfunctional requirements; and 2) how to determine targets of web service design attributes. Currently, the first issue is not addressed and the second one is dealt with subjectively. Quality Function Deployment (QFD), a quality management system, has found its success in improving quality of complex products although it has not been used for developing web service systems. In this paper, we analyze requirements for web services and their design attributes, and apply the QFD for developing web service systems by linking quality of service requirements to web service design attributes. A new method for technical target setting in QFD, based on an artificial neural network, is also presented. Compared with the conventional methods for technical target setting in QFD, such as benchmarking and the linear regression method, which fail to incorporate nonlinear relationships between design attributes and quality of service requirements, it sets up technical targets consistent with relationships between quality of web service requirements and design attributes, no matter whether they are linear or nonlinear
