In this paper, we describe our system for SemEval-2015 Task 3: Answer Selection in Community Question Answering. In this task, the systems are required to identify the good or potentially good answers from the answer thread in Community Question Answering collections. Our system combines 16 features belong to 5 groups to predict answer quality. Our final model achieves the best result in subtas...

This paper presents a novel answer summarization approach for community Question Answering services (cQAs) to address the problem of “incomplete answer”, i.e., missing valuable information from the “best answer” of a complex multi-sentence question, which can be obtained from other answers to the same question. Our method automatically generate a novel and non-redundant summary from cQA answers...

In this article we study the uniqueness problem of an L function belonging to Selberg class with arbitrary meromorphic having finite poles sharing two sets. Actually answer a question raised by Lin-Lin [Filomat, 30(2016), 3795-3806], have significantly improved recent result [Rend. Del. Math. Palermo, (2020)(published online)] authors and that Chen-Qiu [Acta. Sci., 40B(4) (2020), 930-980]. More...

An underdetermined system of linear equation has infinitely number answers. To find a specific solution, regularization method is used. For this propose, we define cost function based on desired features the solution and that answer with best matches to these selected as solution. In case sparse zero-norm function. many engineering cases, there side information which are omitted because Finding...

UNLABELLED Examinations at the Faculty of Medicine of Mu'tah University are based on a single best answer multiple-choice questions (MCQs) format. However, the reliability of this examination format has not been determined. OBJECTIVE Using an examination of obstetrics and gynaecology as a model, this study aims to analyze the difficulty (facility) index, the discriminatory power and reliabili...

As an attempt to better understand how people seek, share, and evaluate information in a social Q&A environment, this study identifies the selection criteria people employ when they select best answers in Yahoo! Answers in the context of relevance research. Using content analysis, we analyzed the comments people left upon the selection of best answers to their own questions. From 1,200 samples ...

Over a hundred years ago Galton reported on the uncanny accuracy of the median estimate of the weight of an ox, as judged by spectators at a country fair [1]. Since then, the notion that the ‘wisdom of the crowd’ is superior to any individual has itself become a piece of crowd wisdom, raising expectations that web-based opinion aggregation might replace expert judgment as a source of policy gui...
