  • Publication number: 20260111458
    Abstract: Embodiments herein relate to employing a RAG system to facilitate document sanitization. An LLM is provided with updated rules via a retrieval system database. The up-to-date rules of the database can be accessed by the LLM and applied to documents for sanitization. The retrieval system database may contain rules instructing the LLM to redact certain components of the documents. The retrieval system database can also be updated through the LLM via the LLM receiving natural language prompts with instructions to update the database with new rules, validate rules, and query for rules, among other things. In some embodiments, the LLM can update the retrieval system database according to changes the LLM detects in documents, deriving rules from the detected changes. The sanitized, or redacted documents outputted by the LLM according to the rules of the retrieval system database can be reworded to maintain user readability and grammatical structure.

  • Publication number: 20190155851
    Abstract: This application discloses an information filtering method and an information processing apparatus. Shared information that is shared by a user account of an online service is obtained. A credibility reference rating associated with the user account is obtained. The credibility reference rating indicates account credibility of the user account. Whether the shared information satisfies a filtering condition is determined based on the credibility reference rating. Further, the shared information is filtered when the shared information is determined to satisfy the filtering condition.

  • Publication number: 20060166955
    Abstract: The present invention relates to a clean process for the degradation of steroidal sapogenin to produce 16-dehydropregnenolone and its analogs. The pure or the crude pseudo steroidal sapogenin, derived from steroidal sapogenin, dissolved in organic solvent, reacts with hydrogen peroxide with or without metal compound and acid as catalyst, and the crude products directly go through elimination and hydrolization in the presence of base to give 16-Dehydropregnenolone or its analog, accompanied with the other product 4R(or S)-methyl-5-hydroxy-pentate, which is converted to 4R(or S)-methyl-?-pentyl lactone after acidification and extraction from the water layer. This technology improved the utilizing degree of steroidal sapogenin, improved the yield, and cleared up the chromium pollution in the former technique. In a word, the method disclosed in this invention is more suitable for manufacture.
