Problems solved by technology
[0007] (1) The network table is not standardized, often without a complete model, and the data in the table still has noise, and even the same entity has different forms of expression;
[0008] (2) For web forms from different data sources, it is difficult to find exact matching snapshots
[0009] For the above-mentioned problems existing in the method of selecting a network table with a snapshot relationship in the related art, no effective solution has been proposed yet

The invention discloses a method and device for selecting network tables with snapshot relations. The method comprises the steps that a set of the network tables is sorted according to the content of entity lists of the network tables, wherein the entity lists are attribute lists capable of marking the records of the network tables; in the sorted network table set, according to a preset rule, a plurality of second tables corresponding to a first table are selected, wherein the second tables are the network tables with the snapshot relations with the first table. Through the method and device, the second tables with the snapshot relations with the first table are selected, the second tables can be used for optimizing inquiry to improve the inquiry efficiency and also can be used in a big data environment, and a system can return part of inquiry results in real time.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a method and device for selecting a network table with a snapshot relationship. Background technique [0002] With the development of information technology, resources on the Internet are becoming more and more abundant. In addition to unstructured data, there are also a large number of network tables. These network tables have a wide coverage and a large amount of information, so they have attracted people's attention. Google has launched the WebTables project to study how to better extract and utilize structured data that exists widely on the Internet; the recently launched Fusion Tables aims to help people integrate and collaborate on data in a cloud environment, and users can upload tabular data And share it with other users, and use the wisdom of everyone to solve the conflicts that may arise during the data merging process through cooperation. In order to make it easier for ...
