Based on analysis of LZ77 compression algorithm, this paper discusses the effect of input error codes to the decoding wordbook and decompression data, and researches error code transmission issue. 分析了主流的LZ77算法编译码原理,讨论了输入误码对译码字典和解压数据的影响,研究了误码传播问题。
FSAS could extract long-words and new-words from texts without wordbook. 本课题实现的频繁序列算法可以在无字典情况下挖掘出文本中的频繁长词和新词。
