Many open domain question answering systems answer questions by first harvesting a large number of candidate answers, and then picking the most promising one from the list. One criterion for this answer selection is type checking: deciding whether the candidate answer is of the semantic type expected by the question. We define a general strategy for building redundancy-based type checkers, buil...

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: which is the best tissue valve for use in the pulmonary position, late after previous repair of tetralogy of Fallot? Altogether 141 papers were found using the reported search, of which 13 represented the best evidence to answer the clinical question. In addition to this, 1 paper...

We provide an analysis of best answers (as chosen by questioners) on Yahoo Answers, a popular online Q&A site with millions of monthly contributors. Our analysis is done mainly through the lens of prediction: we compile a dataset that is as large and fine-grained as any considered before, generate features across a range of different classes, and build a classifier to predict which answers will...

the multivariate exponentially weighted moving average (mewma) control chart is one of the best statistical control chart that are usually used to detect simultaneous small deviations on the mean of more than one cross-correlated quality characteristics. the economic design of mewma control charts involves solving a combinatorial optimization model that is composed of a nonlinear cost function ...

In this paper, we focus on the task of identifying the best answer for a usergenerated question in Collaborative Question Answering (CQA) services. Given that most existing research on CQA has focused on non-textual features such as click-through counts which are relatively difficult to access, we examine the effectiveness of diverse content-based features for the task. Specially, we propose to...

In undergoing this life, many people always try to do and get the best. New knowledge, experience, lesson, and everything that can improve the life will be done. However, many people sometimes feel confused to get those things. Feeling the limited of experience and sources to be better is one of the lacks to own. However, there is a very simple thing that can be done. This is what your teacher ...

Answer Validation is an important step in Automatic Question Answering systems and nowadays by spreading Community Question Answering systems it is known as an important task by itself. Previous works just considered it as a binary classification problem in which they try to find the best answer among all the candidate answers for a question. Accordingly, they do not consider the possible uniqu...
