The Theoretical And Technical Research On Related Search For Electronic Records

With the popularization of computer network technology, e-commerce and other web-based activities are becoming more and more frequent. Thus, a large number of text, pictures, contracts, orders and other electronic records are generated, some of which can be used as the basis for legal disputes. Before the electronic records are used as evidence, we must ensure its authenticity, it should have not been forged or tampered. Traditional search of records usually by setting constraints of the information which the record contained, and then query the database to get the corresponding results. The constraint conditions often have corresponding fields directly in the database. There are some limitations of this search mode, the results searched by this method can only meet the constraints. There is no relationship among the records. However, the electronic record often exists not in isolation, it usually has relationship with other electronic records in practical applications, and this relationship has no directly fields in database, which can be easily got by anglicizing the information of electronic record. This situation can not be solved by traditional search.This paper dynamically define the relationship between electronic records on the basis of describing the electronic record by using ontology, and then get the related records by analysis the rules contained in the relationship property, which can not be get by traditional search. Besides, we proposal correlated signature by combining electronic records and digital signature, which can not only ensure the credibility of the record, but also get related records without searching. In the calculation of the correlated signature, the information of the electronic records associated with the current electronic record will be added in the signature. The detailed information of the record and the associated electronic records with the record should both be got when we search the record, at the same time, the key information of the associated electronic records should be verified. Finally, we will get a chain of electronic records based on correlate signature.Innovation and characteristics of this paper can be summarized into the following two points:Firstly, use ontology to describe the electronic records, and then dynamically create rules through SWRL(Semantic Web Rule Language) language according to the class and the properties contained in the class, finally analysis the rules contained in the relationship property and realize the related search.Secondly, design correlated signature by anglicizing the form of the electronic records, and then realize the search forensics of the correlated signature contained in electronic record.
