METHOD AND SYSTEM FOR INFORMATION RETRIEVAL

摘要

Provided are a method and system for information retrieval. The method comprises configuring a corresponding relationship, on one side whereof are feature nodes within a visual interface and connections between the feature nodes, and on the other side whereof are retrieval units within an information retrieval formula and logic operations between the retrieval units. A visual interface is constructed according to an information retrieval objective, and comprises the feature nodes and their interconnections. The feature nodes within the visual interface and their interconnections are compiled into an information retrieval formula according to the corresponding relationship, and a search is conducted according to this formula. Applying the present technical solution, users can construct complex retrieval formulae, and in particular can retrieve retrieval units of specific types, thereby reducing the difficulty for users of constructing retrieval formulae, expanding information retrieval functionalities and improving information retrieval efficiency.
