摘　　要：半结构化数据与文本数据的异构性导致了它们的索引结构很难一致,因此在XML文档中树型结构索引和文本部分索引的联合创建与协同查询中,一般要用复杂的对应关系进行数据转换。针对这一问题,提出了一种统一的索引结构,简化了对应关系,提高了索引联合创建与协同查询的效率。The heterogeneity of semi-structured data and full-text data causes the difference of their indices. Therefore, during the united creation and the cooperative enquiry of the two indices, data are transformed by complex correspondence. Considering this problem, a unified index structure is presented, which simplifies the correspondence between the indices of heterogeneous data. Thus the efficiency of the creation and enquiry of the unified index is highly improved.

关 键 词：XML 联合索引 协同查询 互关联后继树
