  • Abstract There are two research topics in this thesis. First, we implement a
    highly efficient Chinese input method. Second, we apply a
    divide-and-conquer scheme to the speaker diarization problem.
    The implemented Chinese input method transforms an input first-symbol
    sequence into a character string (a sentence). This means that a user
    only needs to input a first Mandarin phonetic symbol per character,
    which is very efficient compared to the current methods.
    The implementation is based on a dynamic programming scheme
    and language models. To reduce time complexity, the vocabulary for the
    language model consists of 1-, 2-, and 3-character words only.
    The speaker diarization system consists of segmentation and clustering
    modules. The divide-and-conquer scheme is essentially implemented in
    the clustering module. We evaluate the performance of our system using
    the speaker diarization score defined in the 2003 Rich Transcription
    Evaluation Plan. Compared to the baseline, our method significantly
    reduces the processing time without compromising diarization accuracy.
