Embodiment 1

[0025] Such as figure 1 Shown, embodiment 1 of the present invention provides digital library knowledge retrieval method, comprises the following steps:

[0026] S1. Process the materials in the digital library sentence by sentence to obtain the key sentences revealing the knowledge content; convert the key sentences into knowledge units according to the defined knowledge unit structure model;

[0027] S2. Splitting each of the knowledge units into a plurality of RDF triples, creating an instance index according to each of the RDF triples; creating a class index according to the association relationship between all the knowledge units;

[0028] S3. Obtain user input information, search the selected RDF triples related to the user input information in the instance index, and search the associated RDF triples related to the selected RDF triples in the class index Group;

[0029] S4. Return a retrieval result according to the selected RDF triple and its associated RDF triple. ...

Embodiment 2

[0081] Embodiment 2 of the present invention provides a computer storage medium, on which a computer program is stored. When the computer program is executed by a processor, the above-mentioned digital library knowledge retrieval method provided by the above embodiment is realized.

Abstract

The invention relates to the technical field of knowledge retrieval, and discloses a digital library knowledge retrieval method, which comprises the following steps: processing data collected in a digital library sentence by sentence to obtain key sentences for revealing knowledge contents; converting the key statement into a knowledge unit according to a defined knowledge unit structure model; splitting each knowledge unit into a plurality of RDF triples, and creating an instance index according to each RDF triple; creating a class index according to the association relationship among all theknowledge units; obtaining user input information, retrieving a selected RDF triad related to the user input information in the instance index, and retrieving an associated RDF triad related to the selected RDF triad in the class index; and returning a retrieval result according to the selected RDF triad and the associated RDF triad. According to the invention, fine-grained retrieval can be realized, and the knowledge integration level is high.

Description

technical field [0001] The invention relates to the technical field of knowledge retrieval, in particular to a digital library knowledge retrieval method and device. Background technique [0002] As Semantic Web activity is gaining momentum, Linked Data schemas are strong candidates for solving the biggest challenges facing the field of intelligent information management. Just as people publish unstructured text information on web pages and use keyword-based search engines to search for this information, Linked Data technology has been able to easily publish structured information and reliably link this information with other data published on the Internet. Interrelate and go beyond simple keyword searches by using more expressions to query the search result data space. The Linked Data paradigm has evolved to be a powerful enabler for transforming the current document-oriented Web into a network of interconnected data, and ultimately the further development of the Semantic ...
