Structured retrieval method and system for unstructured data

Abstract

The invention discloses a structured searching method of unstructured data. The method comprises the steps that parameters used for searching of the unstructured data and an unstructured data searching script are configured correspondingly according to requirements of searching management operation; the unstructured data searching script is called and analyzed, and parameters needed by the unstructured data searching script are extracted from the configured parameters; the extracted parameters are transmitted to the unstructured data searching script for use, and the corresponding searching management operation is executed. The invention further discloses a structured searching system of the unstructured data. The system comprises a configuration unit, an analysis unit and a searching management operation execution unit, wherein the searching management operation execution unit is used for transmitting the extracted parameters to the unstructured data searching script for use, and executing the corresponding searching management operation. By the adoption of the structured searching method and system of the unstructured data, the searching efficiency is high, and the searching management complexity is low.

Description

technical field [0001] The invention relates to data retrieval management technology, in particular to a structured retrieval method and system for unstructured data. Background technique [0002] At present, the industry mainly uses full-text indexing technology to retrieve unstructured data. Through the traditional method of establishing an inverted index file, the full-text content of unstructured data can be retrieved according to keywords. The so-called inverted index file refers to: an index file based on a main document composed of an inverted index. Each item in the inverted index file includes an attribute value and the address of each record with the attribute value, so that the position of the record is determined by the attribute value. Wherein, the attribute value may be a keyword, and correspondingly, the address of each record having the attribute value is exactly the storage location of the keyword in a master document or a group of master documents. In this...

Problems solved by technology

[0003] However, from the above description of the implementation principle of the existing inverted index retrieval technology, it can be seen that this retrieval technology is based on keywords, so it is more effective for structured data, especially simple text information retrieval. Yes, for the retrieval of unstructured data, such as multimedia information, picture information, report information and other non-text information, it is very inconvenient to use the existing inverted index retrieval technology. Text retrieval operation

[0004] With the development of network technology, especially the rapid development of Internet and Intranet technology, the amount of unstructured data is increasing day by day. If the existing inverted index retrieval technology is still used, not only the retrieval efficiency is low, but also the complexity of retrieval management is also high. will be higher and higher
