Problems solved by technology

These information resources are scattered, independent and heterogeneous, and they come in various forms, data formats, and follow different standards. There has been a lack of effective and unified resource description methods, which has led to scientific and technological information data in It is difficult to deal with cleaning, storage, analysis and calculation in a unified manner, so there are problems such as repeated software development and design, difficult maintenance, and low availability
[0003] The present invention provides an XML-based label description method and device, which helps to solve the problem of unified description of multi-source heterogeneous scientific and technological information resources

Embodiment 1

[0025] Example 1: figure 1 An overall flow chart of a label language design and analysis method for multi-source heterogeneous scientific and technological information resources of the present invention is given. The process of label language design includes the following core modules, such as figure 1 Middle F1-1, F1-2, F1-3 and F1-4; Among them, F1-1 is used to build entity, attribute and relationship database; F1-2, use the existing metadata standard to proofread the extracted entity and attribute and relationships, mainly used for standardization processing; F1-3, the label design process of specific HSTL; F1-4, the Schema of HSTL, used to constrain HSTL. The process relationship between these four modules is sequential, including the following core steps:

[0026] Step 1: Describe entity construction. Combined with the classification method of scientific and technological literature, classify the current main scientific and technological information resources to classif...

Abstract

The invention relates to a label description method and device for multisource isomerism scientific and technical information recourses. The method comprises the steps that the scientific and technical information recourses are classified, and then an object entity library is built; attributes of an object entity are extracted, and an attribute library is built; the object entity and attribute relation are analyzed, and a relation library is built; the object entity, the attributes and an incidence relation are standardized and symbolized; by combining an XML markup language, a grammatical rule of a label description language is defined, and a special description label and a Schema standard of the language are designed; by using an parsing device, according to the grammatical rule of the label language, a description instance is parsed to obtain a description object; the conversion with other data formats and interaction service are provided. According to the label description method and device, the multisource isomerism scientific and technical recourses can be identified more clearly, isomerous data standardization is supported, and uniform description of the multisource isomerism scientific and technical information recourses is achieved; requirements of isomerous data integration, data storage and scientific and technical information recourse data modeling under the occasion of computing processing can be met.

Description
