  <dc:description>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.&amp;nbsp;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.&amp;nbsp;</dc:description>
