Dataset of technologies and stages related to the trusted circulation of data elements

As of 2024, there are 3084 literature and patents related to trusted circulation technology of data elements retrieved from CNKI core journals, WOS database, and the National Patent Office. The table data is divided into 5 columns: text, link similarity, matching link, topic distribution probability, and topic results. The text includes the titles and abstracts of retrieved and screened patents and literature; Link similarity refers to the similarity between the text and each link; The matching process involves selecting the most similar text based on similarity results.

In the matching process, 0 represents data aggregation, 1 represents data processing, 2 represents data hosting, 3 represents data product development, 4 represents data product registration and evaluation, 5 represents data trading and usage, and 6 represents data transmission; The probability of topic distribution is the probability that the text obtained through topic analysis belongs to its dominant topic; The theme result is the theme assignment result in pyLDAvis visualization.
