Description

Technical Field

[0001] This invention relates to the field of collection appraisal technology, specifically to a method and system for grading privately owned collections based on multi-factor weighting. Background Technology

[0002] The grading of privately owned collections is a crucial issue in the field of private collecting, yet it remains unresolved. my country's current Cultural Relics Law provides clear grading regulations for important historical relics and remains possessing cultural, scientific, artistic, and historical value. However, this work is designated to be organized and implemented by the national cultural relics management department, and graded relics are protected and their circulation is restricted. For the diverse and numerous privately owned collections, the relevant national authorities have not issued clear grading regulations, and the field lacks a unified grading standard covering all categories (except for ancient coins).

[0003] "Without rules, there can be no order." The long-standing lack of standardized criteria for grading privately owned collectibles has negatively impacted the popularization and development of private collecting, as well as the trading and exchange of collectibles. The absence of scientific and unified grading standards makes appraisal and evaluation highly subjective and arbitrary, resulting in a lack of transparency and fairness in market transactions, and making it difficult for collectors to make rational and accurate value judgments about their own collections. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a method and system for grading private collections based on multi-factor weighting, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a method for grading privately owned collections based on multi-factor weighting. Includes the following steps: Step 1, Category Evaluation: Receive the category information of the submitted collections and determine the category level of the submitted collections according to the preset collection category evaluation table; wherein, the category level includes six levels from high to low: top grade, rare grade, fine grade, excellent grade, good grade, and common grade.

[0006] Step 2: Determine the benchmark score: Based on the determined category level, select a value corresponding to the upper limit price of that category level as the benchmark score for level evaluation.

[0007] Step 3: Calculation of Level Score: Determine the multiple basic evaluation factors that affect the price of the submitted collectible, and obtain the preset weight ratio of each evaluation factor in the benchmark score; multiply the score of each evaluation factor by its corresponding preset weight ratio and sum them to obtain the total weight ratio of the factor; multiply the total weight ratio of the factor by the benchmark score to obtain the level score of the submitted collectible.

[0008] Step 4: Grade and Price Determination: Compare the grade score with the preset grade and price comparison table to determine the specific grade and actual price range of the submitted collection; wherein, each grade is further subdivided into 5 levels from low to high, for a total of 6 grades and 30 levels.

[0009] Step 5, Conclusion Output: Combine the category evaluation results determined in Step 1 with the level evaluation results determined in Step 4 to generate and output the final rating conclusion for the submitted collection.

[0010] Preferably, the criteria for determining the category level in step one include one or more of the following factors: the production and creation period of the submitted artifact, the status and level of the maker or author, the quality of the materials, the level of craftsmanship, and the quantity in existence. These factors collectively determine the basic grade of the artifact, enabling it to be quickly located in one of the six major grades.

[0011] Preferably, the multiple basic evaluation elements mentioned in step three are preset according to the specific collection category and series to which the submitted collection belongs; wherein, the collection categories include porcelain, jade, bamboo and wood ware, bronze ware, calligraphy and painting, etc. Each major category is further divided into several series, for example, the porcelain category includes Jun, Ru, Ge, and official porcelain series, blue and white porcelain series, famille rose porcelain series, etc.; the jade category includes Shang, Zhou, Warring States and Han jade carving series, Ming, Qing and Republic of China old jade carving series, jadeite carving series, etc. Different series are preset with different combinations of evaluation elements and their respective weight ratios, truly realizing a refined evaluation of "one item, one policy".

[0012] For example, the evaluation factors for blue and white porcelain include age, shape, pattern, painting technique, color, mark, and condition, with age having a pre-set weighting of 40%. For jade carvings, the evaluation factors include age, texture, color, color ratio, purity, shape, size, carving technique, and condition, with texture and color ratio having significantly higher pre-set weightings. This differentiated setting of factors and weights accurately reflects the core differences in the value composition of different categories of collectibles.

[0013] Preferably, the grade price comparison table described in step four defines the price ranges corresponding to the six grades. For example, ordinary grade corresponds to the hundred-yuan level, good grade to the thousand-yuan level, excellent grade to the ten-thousand-yuan level, fine grade to the hundred-thousand-yuan level, rare grade to the million-yuan level, and top grade to the ten-million-yuan level and above. Furthermore, the five levels under each grade further subdivide the price range, realizing the simultaneous completion of grade assessment and price evaluation, and making up for the deficiency of traditional rating only assessing the grade and not the value.

[0014] This invention also provides a multi-factor weighted grading system for privately owned collectibles, including a category evaluation module, a benchmark score determination module, a grade score calculation module, a grade price determination module, and a conclusion output module, for executing the above-described method. Additionally, a computer-readable storage medium stores a computer program thereon for implementing the above-described method.

[0015] The beneficial effects of this invention are as follows: This invention establishes a complete and comprehensive grading system covering major categories of folk collectibles, including porcelain, jade, bamboo and wood artifacts, bronzes, and calligraphy and paintings. Through a standardized process of "first determining the quality, then the grade, and finally the price," and a quantitative calculation method based on multi-factor differentiated weights, subjective artistic evaluation is transformed into objective numerical calculation, greatly improving the scientific rigor, accuracy, and consistency of folk collectible grading. Simultaneously, this method directly links the grading to market price levels, integrating collectible grading with value assessment, providing collectors with intuitive and rational references for collecting and trading. This is of great significance for regulating market order, guiding rational collecting, and promoting the healthy development of the folk collecting industry. Detailed Implementation

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: A multi-factor weighted grading method for privately owned collections The grading method provided in this embodiment consists of two main steps: the first step is to determine the "grade" of the collectible (i.e., which category it belongs to from top-grade to common); the second step is to calculate the specific "level" (i.e., level 1 to 5) within the determined "grade". The final result is a complete grading conclusion of "grade + level" (e.g., "Fine Level 3") and its corresponding market price range.

[0018] Step S1: Evaluate the category of the submitted collection and determine its grade.

[0019] First, experts or users determine the category level (top-grade, rare, fine, excellent, good, common) of the collection based on its macroscopic characteristics and a pre-set "Folk Collection Grading Standard Table". This standard table mainly examines the following basic elements; a collection can be classified into that grade if it meets any one of the standard elements: Manufacturer (Creator): Whether it is a national institution (official production), a national-level industry master, etc., and the classification of its works as superior, medium, or inferior.

[0020] Material of the collectible: Whether it is a rare material (such as Tianhuang stone or chicken blood stone), a precious material (such as gold, sandalwood, Hetian jade, or jadeite), and its superior, medium, or inferior grades.

[0021] Craftsmanship level: Whether it is a high-end craft (such as official masterpieces, imperial palace collections), fine craftsmanship, or folk craft masterpieces, etc.

[0022] Market share: Whether it was collected and used by historical figures, whether it is a unique and rare piece with very few surviving examples, or whether there are clear records of rare collection transactions, etc.

[0023] For example, a piece of Ming Dynasty furniture made of Hainan rosewood, with exquisite craftsmanship and a clear provenance, can be rated as "top-grade" or "precious" based on its material and craftsmanship. A piece of ordinary furniture made of common materials from the Republic of China period, with ordinary craftsmanship, would be rated as "good" or "common".

[0024] Step S2: Determine the baseline score for the level evaluation.

[0025] A benchmark score is assigned to each grade, which is the upper limit of the price range for that grade. For example, refer to the "Collection Grade Value Correspondence Table": The price range for ordinary products (hundred-yuan level) is 100-1000 yuan, with an upper limit of 1000 yuan, so the base score is 1000 yuan.

[0026] The price range for good quality (thousand-yuan level) is 1,000-10,000 yuan, with an upper limit of 10,000 yuan, so the base score is 10,000 yuan.

[0027] The upper limit for premium (ten thousand yuan level) is 100,000, and the base score is 100,000.

[0028] Similarly, the base scores for Fine, Rare, and Supreme are 1,000,000, 1,000,000, and 1,000,000,000, respectively.

[0029] Assuming that in step S1, we determine that a "Qing Dynasty Qianlong Blue and White Lotus Pattern Vase" is a "Fine Item", then its base score is set at 1,000,000.

[0030] Step S3: Determine and calculate the weight score of each evaluation element to obtain the level score.

[0031] This step is the core of the invention, requiring the retrieval of the corresponding "Assessment Element Score Ratio Table" based on the specific series to which the collection belongs. Taking the "Fine" grade "Qing Dynasty Qianlong Blue and White Lotus Pattern Vase" as an example, it belongs to "Porcelain Series Five: Blue and White Porcelain Series".

[0032] Retrieve the evaluation elements and preset weight ratios for this series (for ease of explanation, the ratio values ​​have been converted to decimals): Period (40%): This vase dates to the Qianlong reign (one of the three emperors of the Qing Dynasty), corresponding to a score of 10%. (See data: Qing Dynasty Blue and White Porcelain 10%) Vessel shape (15%): This bottle is a standing porcelain piece, which corresponds to a score of 15%.

[0033] Pattern (10%): The theme is intertwined flowers, corresponding to a score of 4%. (See data: Flowers 4%) Craftsmanship (15%): The craftsmanship is exquisite, and the corresponding score is 15%.

[0034] Hair color (5%): The hair color is pure and in line with the characteristics of the times, and the corresponding score is 5%.

[0035] Inscription (5%): The base is inscribed with the reign mark "Made in the Qianlong Reign of the Great Qing Dynasty", which corresponds to a score of 5%.

[0036] Condition (10%): Well preserved, corresponding to a score of 10%.

[0037] Adding up the scores of each element, we get the total weight ratio of the elements = 10% + 15% + 4% + 15% + 5% + 5% + 10% = 64%.

[0038] Then, calculate the level score = total weight percentage of the element × baseline score = 64% × 1,000,000 = 640,000.

[0039] Step S4: Determine the specific level and price of the collection.

[0040] The calculated grade score is compared with the price sub-ranges of each grade (Fine) in the "Collection Grade Value Correspondence Table": Premium items (priced between 100,000 and 1,000,000 yuan) are categorized as follows: Elite Level 1: Over 200,000 yuan Elite Level 2: Over 400,000 yuan Elite Level 3: Over 600,000 yuan Elite Level 4: Over 800,000 yuan Elite Level 5: Under 1,000,000 yuan With a score of 640,000 yuan, the item falls into the "Fine Level 3: 600,000 yuan and above" range. Therefore, the item is rated as "Fine Level 3," with a market reference price range of 600,000 to 800,000 yuan.

[0041] Step S5: Generate the final rating conclusion.

[0042] The grade result from step S1 is combined with the level result from step S4 to output the final rating conclusion: the "Qing Dynasty Qianlong Blue and White Lotus Pattern Vase" is rated as "Fine Grade 3", with a market reference value between 600,000 and 800,000 yuan.

[0043] Application Examples For different categories of collectibles, this method only requires changing the evaluation elements and weight table in step S3. For example, evaluating a "modern Hetian white jade Guanyin statue": Grade Determination: Based on its superior raw material quality and exquisite carving craftsmanship, it is classified as "Fine" or "Rare". Assuming it is classified as "Fine", the base score is 1,000,000.

[0044] Calculate the level: Call the scale table of "Jade Series IV: New Jade Carvings after the Founding of the People's Republic of China".

[0045] Period: After the 1980s (5%) Origin: Hotan seed jade (10%) Jade quality: Oiliness (15%), fineness (15%), purity (10%), color (8%), totaling 48%. Specifications: 500g-1000g (12%) Jade color: White jade (10%) Vessel type: Statues (10%) Sculpture style: Round carving (15%) Condition: Excellent (10%) Total weighting percentage = 5% + 10% + 48% + 12% + 10% + 10% + 15% + 10% = 120%. Level score = 120% × 1,000,000 = 1,200,000. This score exceeds the upper limit of the "Fine" level, indicating that the item should actually be classified as "Rare." It needs to be reclassified in step 1, or assessed as "Fine Level 5 (upper limit)," demonstrating the method's dynamic adjustment capability for high-value items. If reclassified as "Rare," with a baseline score of 10,000,000, then a score of 1,200,000 corresponds to Rare Level 1 within the Rare category, making the conclusion more reasonable. Example

[0046] Corresponding to the above method, this invention also provides a rating system that can be deployed on a computer or mobile terminal. The system includes a database for storing category evaluation tables, weight tables for evaluation elements of each series, and grade-price comparison tables. Users input or select various characteristics of the collectibles through an interactive interface, and the system automatically executes the above calculation steps in the background, instantly outputting the rating results and reference prices. This system greatly lowers the rating threshold and ensures the consistency and objectivity of the rating results.

[0047] Through the above methods and systems, this invention has successfully constructed a scientific, systematic, quantifiable, and easy-to-operate rating system for private collections, filling a gap in the industry and having significant practical value for promoting the healthy, standardized, and transparent development of the private collection industry.

[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
