4results about How to "Achieve fairness" patented technology

The application discloses a kind of settlement balance transparent data labeling crowd sourcing method, system and medium, method includes: establishing data labeling crowd sourcing system, determine interactive entity;Task requester mixes and is labeled data and unlabeled data to obtain to be labeled data, while setting the public condition of labeled data, public task information tuple after encryption through smart contract on blockchain, deposit task reward setting task deposit, public task download link;Worker confirms to accept task and deposits task deposit, generates proof after downloading and completing data labeling task, and public task result and proof;Task requester worker proof, evaluate task result, create and broadcast a piece of hash time lock transaction, pay task reward to worker.The application carries out fair trade under the supervision of no trusted third party by blockchain and hash time lock, realizes the objectivity and fairness of task reward distribution, guarantees the balance and transparency of task reward settlement.

The application discloses a spoken language evaluation system and method based on multiple dimensions, and relates to the technical field of data processing.The system comprises the following steps: obtaining audio text, a phoneme list and a phoneme time boundary list corresponding to speech data according to a pre-trained text phoneme recognition model; calculating a fluency score according to the phoneme list and the phoneme time boundary list; obtaining a semantic score of the audio text through a pre-trained semantic model; obtaining a syntax score of the audio text through a pre-trained syntax model; matching the audio text and an answer text according to a text matching method based on an edit distance to obtain a text matching score; obtaining a pronunciation score of the audio data finally through phoneme confidence of the phoneme list; dynamically adjusting the weight of each dimension score according to the length of the audio text, and calculating a final spoken language evaluation score; and the application comprehensively evaluates the spoken language ability through multi-dimensional evaluation and dynamic weight adjustment according to the scene, and realizes the comprehensiveness, fairness, accuracy and high efficiency of the spoken language evaluation.

The application belongs to the technical field of military research data management, and discloses a data right protection and contribution calculation system of a block chain, which comprises: an application layer, which is used for providing trusted military research data based on a block chain core layer to realize data evidence, whole-process operation tracing, multi-dimensional contribution calculation and auditing functions for a collaborative research and development scene; an enhanced component layer, which is used for providing management services, data scheduling, user access and security enhancement support for the application layer; a block chain core layer, which is used for providing block chain basic capabilities supporting multi-chain collaboration, high-throughput consensus, automatic execution of intelligent contracts, national secret level security protection and trusted node management; and an infrastructure layer, which provides computing, storage and network resources for the application layer, the enhanced component layer and the block chain core layer. The application realizes data right protection and contribution calculation by adopting block chain encryption algorithms, consensus mechanisms, distributed ledgers and intelligent contracts and other technologies.
