【摘要】 针对全文检索模型的研究,在双排序互关联后继树(DIRST)模型的基础上,进行了索引压缩,并在此基础上提出了一种新的原文生成算法。实验表明,DIRST模型的空间效率和时间效率都得到了显著的提高。更多还原

【Abstract】 To study Full-text index models,this paper introduced new index compression and original text generation algorithms of Dual Sorted Inter-relevant Successive Trees.Experiments have shown that both space and time efficiency of DIRST model has been apparently improved.更多还原
