This paper investigates how the angular resolution of a simulated light field display affects viewing experience 3D rendered scene. The effect three-dimensionality, helpfulness motion parallax, and overall are evaluated by mean quantitative user study. A total 32 results recorded evaluated. quality metrics show logarithmic trend, improving with an increasing number views. plateau at 0.25° ...

As students read expository text, comprehension is improved by pausing to answer questions that reinforce the material. We describe an automatic question generator that uses semantic pattern recognition to create questions of varying depth and type for self-study or tutoring. Throughout, we explore how linguistic considerations inform system design. In the described system, semantic role labels...

This paper describes the procedure adopted by the three coordinators of the CLEF 2003 question answering track (ITC-irst, UNED and ILLC) to create the question set for the monolingual tasks. Despite the little resources available, the three groups collaborated and managed to formulate and verify a large pool of original questions posed in three different languages: Dutch, Italian and Spanish. A...

We study the impact of syntactic and shallow semantic information in automatic classification of questions and answers and answer re-ranking. We define (a) new tree structures based on shallow semantics encoded in Predicate Argument Structures (PASs) and (b) new kernel functions to exploit the representational power of such structures with Support Vector Machines. Our experiments suggest that s...

In this paper we explore how compositional semantics, discourse structure, and the cogni-tive states of participants all contribute to pragmatic constraints on answers to questions in dialogue. We synthesise formal semantic theories on questions and answers with techniques for discourse interpretation familiar from computational linguistics, and show how this provides richer constraints on resp...

In recent algebra investigations, the maximum number of islands on some grid turned out to appear as interesting combinatorial problem. The aim of this paper is to overview the history and the results in this topic. The first result, the formula of Gábor Czédli appeared in [2], his proof was based on lattice theory. The investigation went on two different directions, nowadays both are living re...

Open forum threads exhibit a great variability in the quality and quantity of the answers they attract, making it difficult to manually moderate and separate relevant from irrelevant content. The goal of SemEval 2015 Task 3 (Subtask A, English) is to build systems that automatically distinguish between relevant and irrelevant content in forum threads. We extend a short answer assessment system ...

This paper describes the KeLP system participating in the SemEval-2016 Community Question Answering (cQA) task. The challenge tasks are modeled as binary classification problems: kernel-based classifiers are trained on the SemEval datasets and their scores are used to sort the instances and produce the final ranking. All classifiers and kernels have been implemented within the Kernel-based Lear...
