Embodiment Construction

[0137] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0138] With the advent of the era of big data, there are more and more application scenarios for data, and data can provide people with effective reference and help in judgment. However, if the integrity of the data is insufficient, the project information that users want to know may not be found when they query according to their needs, or even if they are found, the project information found cannot effectively reflect the actual situation.

[0139] Taking the knowledge map as an example, the knowledge map constructed from a large amount of data can reflect the relationship between the data, as well as the overall trend of the data and the content of the data, and can provide users with practical and valuable references. Taking film and television data as an example, the knowledge map established through film and television data can provide users with relevant in...

Abstract

The embodiment of the invention discloses a method for determining a data cluster optimization direction. Aiming at a plurality of data of the same type in a to-be-optimized data cluster, the quantityof each item information in the data can be collected; therefore, a first effective value for the first item information and a second effective value for the second item information are determined; the first effective value can reflect the degree of the first item information in the plurality of pieces of data, the second effective value can reflect the degree of the second item information in the plurality of pieces of data, and then the coincidence relation between the first effective value and the preset condition and between the second effective value and the preset condition can be judged according to the preset condition, and the optimization direction of the data cluster is determined according to the coincidence relation, so that a user can clearly know which part needs to be optimized, and through the embodiment of the invention, the human experience influence during the determination of the optimization direction is removed, and the optimization accuracy and the optimizationefficiency are improved. The embodiment of the invention further discloses a quality assessment method and device.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a data processing method and device. Background technique [0002] With the advent of the era of big data, there are more and more data application scenarios, such as building knowledge graphs based on data provided by data sources. [0003] In order to improve the application effect of data, there is a higher requirement for data integrity. For example, if the integrity of the data used to build the knowledge map is insufficient, such as the project information corresponding to some objects in the data is incomplete, then when the user uses the knowledge map, the project information that the user may want to know may not be found, or even if It is found that the project information found cannot effectively reflect the actual situation. [0004] For this reason, it is necessary to optimize the data for constructing the knowledge map to improve the quality of the knowled...
