  • This paper discusses a decision-tree approach to the problem of assigning probabilities to words following a given text. In contrast with previous decision-tree language model attempts, an algorithm for selecting nearly optimal questions is considered. The model is to be tested on a standard task, The Wall Street Journal, allowing a fair comparison with the well-known trigram model.

  • 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 syntactic information helps tasks such as question/answer classification and that shallow semantics gives remarkable contribution when a reliable set of PASs can be extracted, e.g. from answers. ...

  • In this work we address the task of computerassisted assessment of short student answers. We combine several graph alignment features with lexical semantic similarity measures using machine learning techniques and show that the student answers can be more accurately graded than if the semantic measures were used in isolation. We also present a first attempt to align the dependency graphs of the student and the instructor answers in order to make use of a structural component in the automatic grading of student answers. ...

  • We present a graph-based semi-supervised learning for the question-answering (QA) task for ranking candidate sentences. Using textual entailment analysis, we obtain entailment scores between a natural language question posed by the user and the candidate sentences returned from search engine. The textual entailment between two sentences is assessed via features representing high-level attributes of the entailment problem such as sentence structure matching, question-type named-entity matching based on a question-classifier, etc.

  • In this paper, we analyze the impact of different automatic annotation methods on the performance of supervised approaches to the complex question answering problem (defined in the DUC-2007 main task). Huge amount of annotated or labeled data is a prerequisite for supervised training. The task of labeling can be accomplished either by humans or by computer programs. When humans are employed, the whole process becomes time consuming and expensive.

  • however these are often based on a specific text type or genre, e.g. financial newspaper text (the Penn-II Treebank (Marcus et al., 1993)). This can limit the applicability of grammatical resources induced from treebanks in that such resources underperform when used on a different type of text or for a specific task. In this paper we present work on creating QuestionBank, a treebank of parse-annotated questions, which can be used as a supplementary training resource to allow parsers to accurately parse questions (as well as other text). ...

One statement supports the author’s argument better than the others do.

  • The process of counting correct answers began by assigning a value to the responses to each question (Table 6). Where countries have substituted questions, or reworded them, we have also given a value of 1 to a correct response and 0 in all other cases. In the case of a country with fewer than 8 financial knowledge questions we have rescaled each score as necessary (typically multiplying by a factor of 8/7).

  • The development of the catalytic converter was society's response to smog problems. The installation of this clever device in the exhaust system has been mandatory on all new cars sold in the United States since 1975. It accomplishes three tasks, with varying degree of effectiveness: it converts any CO in the combustion products to CO2. It also facilitates the combustion of any unburned hydrocarbons to carbon dioxide and water. Finally, it also helps to reduce the emissions of nitrogen oxides by transforming them into the harmless nitrogen (N2).
