In this work, a best answer recommendation model is proposed for a Question Answering (QA) system. A Community Question Answering System was subsequently developed based on the model.  ...  The system eliminated longer waiting time faced by askers in a community question answering system. The developed system can be used for research and learning purposes.  ...  For a question q with a voter, i v making a choice of his answer i a , on question q Q , the voter score, i r is obtained as in Equation (1) : { }{ } { } [ ] : 1 ,1 i q i j i i q Q k v V r a a r i V  ...

Q-Methodology Explained by Comparing Q-Sort Survey with Conventional R-Sample Survey and Relating Factor Analysis Described

Wim Moree
2017 Civil Engineering Research Journal  
This article is intended to concisely describe the difference between the use of the conventional R-sample survey and Q-sort survey on the basis of a single variable example and to describe the meaning  ...  This contrary to the use of conventional R-sample survey which is not suitable for measuring subjective opinions and reflections.  ...  For this purpose, you can perform a conventional survey among a sample of a randomly selected number of voters in the target group whom you ask their opinions on statements in the election manifesto.  ...

Landmark-Based Route Recommendation with Crowd Intelligence

Bolong Zheng, Han Su, Kai Zheng, Xiaofang Zhou
2016 Data Science and Engineering  
Given a pair of user-specified origin and destination, a route recommendation service aims to provide users with the routes of the best travelling experience according to given criteria.  ...  Unfortunately, latency of crowdsourced systems is usually high, because they need to generate tasks and wait for workers' feedbacks before answering queries.  ...  In this way, the worker with high accumulate familiarity score will get a relatively high preference score and ensure the preference score will not result in a bias in worker selecting.  ...

An Iterative Method for Calculating Robust Rating Scores

Mohammad Allahbakhsh, Aleksandar Ignjatovic
2015 IEEE Transactions on Parallel and Distributed Systems  
In this paper we introduce an iterative voting algorithm and then use it to obtain a rating method which is very robust against collusion attacks as well as random and biased raters.  ...  Our tests demonstrate high efficiency of our method, especially for very large online rating systems, for which trust management is both of the highest importance and one of the most challenging problems  ...  For this purpose we introduce for each list Λ l a Lagrangian multiplier λ l , define λ = λ l , : 1 ≤ l ≤ L and look for the stationary points of the Lagrangian function Φ( ρ, λ) = F ( ρ) − L q=1 λq −1  ...

We present a general model for opinion dynamics in a social network together with several possibilities for object selections at times when the agents are communicating.  ...  In particular, we provide an answer to the open problem of the convergence property of the top-k selective gossip model, and show that the convergence holds in a much more general setting.  ...  one, and hence, we naturally have S(t) = {1} for all t ≥ 0. • Top-k Selective Gossiping: The top-k selective gossiping model that was proposed and analyzed in [12] is a special case of the above dynamics  ...
