[Objective] This paper tries to address the issues facing sci-tech big data, such as source dispersal, low quality, and poor content. [Methods] We used value-added computing methods, such as data cleansing, entity alignment, entity field fusion, conflict detection, etc., to develop tools for the enrichment of sci-tech big data. [Results] The developed tools achieved entity data alignment at the levels of personnel, organization, conference, journal and relationship among them. The contents of the entity fields were increased by 5 to 10 times, and the entity analysis dimension was increased by 2 to 3 times. [Limitations] The timeliness and standardization of value-added data need to be optimized and improved based on service needs. [Conclusions] The proposed methods and tools enhance the knowledge discovery of the sci-tech big data and intelligent information analysis systems.
