inverted query 中文意思是什麼
inverted query
解釋
倒排詢問-
Experiments indicate that the inverted index based on schema gets the best trade - off between space cost and query efficiency. this result is useful for the design of future search engine for xml
實驗結果表明本文提出的兩種倒排索引的空間開銷得到了顯著改善，其中基於模式的倒排索引獲得了最好的存儲空間與查詢效率的權衡。 -
Xml information retrieval syslem differs greatly from traditional information retrieval system in the construction of both inverted text index and structural index, the evaluation of both keyword based query and structure based query, and the effects of structural information on result relevance ranking
Xml信息檢索系統與傳統的信息檢索系統不同，主要體現在：建立索引時不僅需要建立倒排文本索引，還需要建立結構信息索引；查詢處理時不僅需要處理關鍵字查詢條件，還需要處理結構化查詢條件。 -
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
為此，本文首先提出了一種基於f & b索引的xml數據的磁盤壓縮存儲結構ldf & b ，其優點在於:一方面， ldf & b摒除了傳統存儲方法中相同的值信息重復存儲帶來大量冗餘的問題;另一方面，該結構引入的同帶索引與反向索引結構將具有相同性質的節點聚集在一起，使得可以快速的定位到滿足條件的節點集，很好的支持了其上的查詢處理。
