We address the problem of evaluating textual, task-oriented dialogues between the customer and the helpdesk, such as those that take the form of online chats. As an initial step towards evaluating automatic helpdesk dialogue systems, we have constructed a test collection comprising 3,700 real Customer-Helpdesk multiturn dialogues by mining Weibo, a major Chinese social media. We have annotated ...

This paper investigates the development of weld zone in Resistance Spot Welding (RSW) which focuses on weld nugget and Heat Affected Zone (HAZ). The effects of four factors namely weld current, weld time, electrode force and hold time were studied using a general 2 factorial design augmented by five centre points. The results of the analysis showed that all selected factors except hold time exh...

Most surrogate models for computer experiments are interpolators, and the most common interpolator is a Gaussian process (GP) that deliberately omits a small-scale (measurement) error term called the nugget. The explanation is that computer experiments are, by definition, “deterministic”, and so there is no measurement error. We think this is too narrow a focus for a computer experiment and a s...

Abstract Liver is a by-product that can be used as raw material for nuggets because it has the nutrients needed growth especially children. Processing liver into diversification effort. Different flours will produce different final products. The purpose of this research was to determine chemical quality and amino acid profile with filler agents. materials were fresh chicken beef liver, cornstar...

Beef meatballs and chicken nuggets are popular processed meat products that in great demand. Currently, many micro, small, medium enterprises (MSME) produce beef then sell them through online e-commerce. Bandung City is one of the cities with 121,530 (26.17%) out 464,346 MSMEs food sector. This study aims to evaluate safety produced by sales various Indonesia. The content sodium borate (borax) ...

When the objective of an information retrieval task is to return a nugget rather than a document, query terms that exist in a document will often not be used in the most relevant information nugget in the document. In this paper, a new method of query expansion is proposed based on the Wikipedia link structure surrounding the most relevant articles selected automatically. Evaluated with the Nug...

We propose a method with better predictions at extreme values than the standard method of Kriging. We construct our predictor in two ways: by penalizing the mean squared error through conditional bias and by penalizing the conditional likelihood at the target function value. Our prediction exhibits robustness to the model mismatch in the covariance parameters, a desirable feature for computer s...
