In this paper, we describe our approaches that we used for the NTCIR-8 Community QA Pilot task and report on its results. Specifically in the pilot task, we mainly focused on discovering effective features for evaluating quality of answers, for example, features on relevance of an answer to a question, authority of an answerer, or informativeness of an answer. Also, we examined two different st...
In this article, by using Chebyshev’s polynomials and Chebyshev’s expansion, we obtain the best uniform polynomial approximation out of P2n to a class of rational functions of the form (ax2+c)-1 on any non symmetric interval [d,e]. Using the obtained approximation, we provide the best uniform polynomial approximation to a class of rational functions of the form (ax2+bx+c)-1 for both cases b2-4a...
This paper describes a question answering program which divides question answering into two separate processes: answer formation and answer expression. Rather than gathering possible answers and choosing the best among them, the program accesses the database and finds all components of possible answers, e.g. a causal chain, and then passes this information to an expression program which formula...
Solution 1: The goal of MLE is to estimate optimal values for each of the model’s parameters by maximizing the likelihood of the data given the parameters. MLE provides an answer to the question “which model instance best fits the data?” when “best fits” is defined as “gives the most evidence for”. If θ is a particular assignment of values to the model’s parameters and y represents the observed...
