ab: Summary: The accumulated question-answer archives in community-based
    question answering (CQA) services have produced a valuable repository
    for knowledge discovery. The yes-no question is a common type of
    question which has not been well studied in previous work. This paper
    proposed a novel approach to analyze answers to Chinese yes-no
    questions in CQA services. The analysis task was innovatively formed as
    a sentence selection problem: sentences that best expressed the
    answerer’s opinion were selected. First, a conditional random field
    (CRF) based annotation model was proposed to split the question into
    several segments. Then a new score function, which combined position
    information of the sentence and segmentation information of the
    question, was designed to score all sentences of one answer. Experiment
    results validated the effectiveness of the CRF-based question
    segmentation method. The proposed answer scoring function was also
    proved to be more appropriate than other approaches with respect to
    satisfying user’s information need.
