Abstract

The invention discloses a prediction method and device for a SparQL query statement, and relates to the technical field of computers, and one embodiment of the method comprises the steps of obtainingat least one SparQL query statement used by a user at a historical moment; carrying out one-hot coding on each component of the graph mode sequence corresponding to each SparQL query statement to forma feature vector of the SparQL query statement, wherein the components comprise at least one of the following components: resource description framework (RDF) triples, operators among the triples, and left and right brackets for determining a nesting relationship among the triples; inputting the feature vector of each SparQL query statement into a pre-trained Seq2Seq model according to a preset time sequence to obtain a target query statement serving as a prediction result; and caching query result data of the target query statement. According to the embodiment, the accuracy of SparQL query statement prediction can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for predicting SparQL query sentences. Background technique [0002] Linked Data is a semantic data network that computers can understand, and has now developed into a knowledge base that can provide a large amount of open data. Among them, some knowledge bases are composed of millions of concepts described by Resource Description Framework (RDF) triples, such as DBpedia, FOAF and so on. Users access data in these repositories using public SparQL clients that allow users to make SparQL queries. SparQL (SPARQL Protocol and RDF Query Language) is a query language and data acquisition protocol developed for RDF, which can be used for any information resources that can be represented by RDF. [0003] Continuous SparQL queries issued by users from the same client usually show certain patterns, such as the current query is the same or similar to the resources qu...
