Problems solved by technology

However, this solution is not easy to expand, and the flexibility is not enough. If you need to integrate new types of files, you need to modify the metadata standard file
Moreover, when retrieving metadata standard files, it is necessary to traverse a lot of attribute information irrelevant to the retrieved target files, which affects the retrieval effect
[0005] In summary, the retrieval effect of heterogeneous digital content (including multiple types of files) in the prior art is not ideal

Embodiment Construction

[0032] The embodiment of the present invention creates a standard metadata file for each type, and enters the attribute information of files of the same type into the corresponding standard metadata file, so as to search through the standard metadata file. In this way, there is no need to search across systems, nor to traverse the entire metadata standard file (equivalent to all metadata standard files in this embodiment), which improves the efficiency of data search.

[0033] In this embodiment, the different types of the multiple files refer to the different attribute structures of the multiple files, and the different attribute structures include different formats of the files. For example, the format of an electronic book is PDF, and the format of an electronic picture is JPG. The two formats are different and belong to different types. For another example, the format of the electronic book and the electronic periodical are both PDF, but the attribute of the electronic per...

Abstract

The invention discloses methods for integrating and searching data, which are used for realizing the improvement of a data entry way, realizing the integration of a plurality of types of documents and improving the data search efficiency. The method for integrating the data comprises the following steps of: determining the type of a document to be integrated; judging whether the type is an existing type or not; if not, creating a metadata standard document according to the attribute structure of the type; entering attribute information of the document to be integrated into the metadata standard document corresponding to the type; entering the document to be integrated and establishing an index of the attribute information to the document to be integrated. The invention further discloses devices for realizing the two methods.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a method and device for data integration and search. Background technique [0002] With the development of computer technology, e-books have entered people's lives and become popular. People began to consult e-books through electronic databases. Network technology has further promoted the development of electronic databases and electronic books. A wide variety of data files are stored and accessed electronically. [0003] Currently, the retrieval system is divided into multiple sub-retrieval systems, and different sub-retrieval systems are used to retrieve different types of documents. It can be seen that the retrieval system needs to be compatible with multiple different sub-retrieval systems, which has high complexity and is not easy to maintain and manage later. And the retrieval effect across sub-retrieval systems is not good. [0004] In order to solve the pro...
