3.1 Efficiency Analysis In traditional models and methods, the time taken for an alternative term to be approved as a standard term can be described by the following equation (1): T = ∫₀ᵗ [n₁ * f(t) + n₂ * f(t)] dt (1) Here, T represents the time for a proposed term to become a standard term. In traditional models, users submit proposals for alternative terms to be standardized, and each proposal undergoes manual review (where feedback is provided once the proposal is reviewed and approved). The feedback time mainly depends on the work hours of the reviewing personnel. Two scenarios are considered: Scenario 1 (Short processing time): The reviewer immediately checks the proposal. In this case, the review time is t₁, and the number of terms reviewed is n₁. Scenario 2 (Longer processing time): The reviewer does not immediately check the proposal. In this case, the number of terms reviewed is n₂, and the review time follows an exponential distribution, with the probability density function of review time, f(t), being: f(t) = (0.08) * e^(-0.08t) This model extends to the alternative terms, and the time taken for a term to become standardized is described by the following equation (2): T = (n₃ * t₃) + (n₄ * t₄) (2) Here, T is the time for a proposed term to become standardized, with n₃ representing the number of valid terms that are stored in the blockchain, and n₄ representing invalid terms. The blockchain model allows registered users to submit alternative terms via an Excel file and validate these terms using smart contracts. For this process, the validation and blockchain writing time largely depend on the smart contract execution time and blockchain transaction speed. Once terms are submitted, they are validated against the smart contract. Based on the feedback, terms are categorized into those that can be stored in the blockchain (valid terms) and those that cannot (invalid, synonymous, or defective terms), with counts n₃ and n₄ respectively. The Ethereum blockchain is used for the validation and writing process. Assuming the average time for writing is t₄, and considering the Ethereum throughput of tx transactions per second, the proposed model's time can be summarized by the equation above. In both the traditional model and the blockchain model, the terms n₁, n₂, n₃, n₄ account for 50% of the total terms processed.
