该结构与文档中倒排序方法相结合，提出了一种基于mpeg - 7标准的倒排索引机制及其索引建立算法。 |
| 5. | 4 ) we study the keyword search for xml in relational databases , present two new inverted list indexes : extended inverted index based on containment relationship and inverted index based on schema
4 )提出了两种新的倒排索引技术，该倒排索引技术可应用于xml文档的摘要检索。 |
| 6. | To maximize the efficiency of lookups , only a subset of the tokens in each row in the table is indexed in the inverted index structure that the fuzzy lookup transformation uses to locate matches

| 10. | So at first in this paper , a disk - based xml data storage structure ldf & b based on f & b index is proposed . on one side , ldf & b wipes off the redundancy existing in traditional storage structure which stores the same value information repeatedly ; on the other hand , the index on the tape and the inverted index introduced in this storage structure enable nodes with the same property to be clustered when stored on disk , and enable nodes satisfied with the query to be searched effectively . that is to say , ldf & b can support xml query processing effectively
为此,本文首先提出了一种基于f & b索引的xml数据的磁盘压缩存储结构ldf & b ,其优点在于:一方面, ldf & b摒除了传统存储方法中相同的值信息重复存储带来大量冗余的问题;另一方面,该结构引入的同带索引与反向索引结构将具有相同性质的节点聚集在一起,使得可以快速的定位到满足条件的节点集,很好的支持了其上的查询处理。 |
