  • Publication number: 20240116960
    Abstract: Disclosed is a method of preparing glufosinate, and specifically a method of preparing glufosinate represented by formula (1) or its salt or enantiomer, or a mixture of its enantiomers in any ratio, comprising a step of hydrolyzing a compound of formula (III) to generate a compound of formula (1). Due to a distinctive reaction mechanism adopted in the method of the present disclosure, a halogenated hydrocarbon by-product in the Michaelis-Arbuzov reaction can be avoided and thus the destructive impact of the halogenated hydrocarbon by-product on ozone in the aerosphere can be prevented. Accordingly, the equipment and engineering investments required for the separation, purification, and collection of the foregoing by-product are eliminated, and the potential environmental and safety hazards brought by the foregoing by-product are also avoided.

  • Patent number: 11947914
    Abstract: In embodiments of the present disclosure, there is provided an approach for fact checking based on semantic graphs. According to embodiments of the present disclosure, after obtaining a text to be fact checked, a plurality of evidence sentences related to the text are retrieved from an evidence database. Then, semantic graphs of the text and the evidence sentences are constructed based on the semantic analysis, and a veracity of a statement in the text can be determined based on the semantic graphs. Embodiments of the present disclosure propose a graph-based reasoning approach for fact checking, and use the constructed semantic graphs to facilitate verification of the truthfulness of the text, thereby improving the accuracy for fact checking.

  • Patent number: 10545932
    Abstract: A method for cleaning data stored in a database, the method comprising providing a set of fixing rules. Each fixing rule incorporates a set of attribute values that capture an error in a plurality of semantically related attribute values, and a deterministic correction which is operable to replace one of the set of attribute values with a correct attribute value to correct the error. The method further comprises comparing at least two of the fixing rules with one another to check that the error correction carried out by one fixing rule is consistent with the error correction carried out by another fixing rule.

  • Patent number: 10162857
    Abstract: The optimized inequality join method is a method for joining relational tables on input inequality conditions. The optimized inequality join method is a relatively fast inequality join method using permutation arrays to store positional information for sorted attributed values. Additionally, space efficient bit arrays are used to enable optimization, such as Bloom filter indices, thus providing faster computation of the join results. The method may be used, for example, for joining various inequalities associated with a variety of measured environmental conditions for raising an alarm when certain conditions are met.

  • Publication number: 20160004743
    Abstract: A method for cleaning data stored in a database which utilises a data fixing rule. The data fixing rule comprises a set of attribute values that capture an error in a plurality of semantically related attribute values. The data fixing rule also comprises a deterministic correction which is operable to replace one of the set of attribute values with a correct attribute value to correct the error. The method comprises applying the data fixing rule to the database to detect if the set of attribute values that captures the error is stored in the database and, if the set of attribute values is detected, the method applies the deterministic correction to correct the error in the attribute values.
