提出了一个用于全文信息检索系统的检索算法。该算法以集合理论为指导,既考虑了按可检词检索,也考虑了按诸外部特征项检索。经试验表明,这一算法行之有效,具有较大的工程实用价值和较普遍的适应性。
A retrieval algorithm for full text information retrieval system is proposed. Guided by the set theory, the algorithm not only considers the searchable words, but also searches according to the external features. The experiment shows that this algorithm is effective, has a greater engineering practical value and more general adaptability.
