Solution:Weighting in token distribution by Ecrits( coffee review)

By describing product experiences, "you" become the bridge between distribution from producers and waste recycling after consumption.

Implement a token economy with Atala prism, we will design and implement a token drop for actual coffee consumption review submissions(Ecrits).

Solution Details

Valueway will grant native tokens through Ecrits, which will be calculated independently based on the Maximal Marginal Relevance (MMR) according to the contents of the Ecrits in three ways This will allow us to distribute tokens that will benefit consumers in a unique way on next phase.

Maximal Marginal Relevance（MMR） The basic score of Ecrits is calculated using Maximal Marginal Relevance (MMR) in text summarization. MMR is a method that calculates the importance of words in a summary based on their importance and novelty in the overall summary. The following is a draft of the method for determining importance and novelty.

A. Calculation of Importance Calculate the importance of each word. TextRank may be used to calculate importance, but for applying it to Ectits, it may be more appropriate to prepare a set of Ectits for a specific industry and consider evaluation within this set using CollabRank [1]. This may allow the detection of important words for each cluster of viewpoints, such as an overview of a store or food and beverage offerings. The range of importance values is [0, 1]. For the importance of sentences, divide the total importance calculated by summing the importance of unique words in the sentence by the total importance calculated for the Ectits and calculate the average importance. As Ectits may contain unique expressions, such as repeating the same word multiple times consecutively (e.g. "delicious, delicious, delicious"), only unique words are used. This is expected to result in higher evaluation values for Ectits sentences that describe important points using different words. (A page that summarizes this in an easy-to-understand manner can be found below, but for more detailed information, the following paper [1] proposing CollabRank may be more suitable as an official document.)

In Proceedings of the 22nd International Conference on Computational Linguistics (Coling 2008), pages 969–976, Manchester, UK. Coling 2008 Organizing Committee. https://aclanthology.org/C08-1122/

B. Calculation of Novelty Calculate how much novel information is provided by the Ectits. Vector similarity using word embeddings is used here. The latest N reviews from the already posted Ectits collection are used as the reference. The average vector of word embeddings is calculated for this reference Ectits. The cosine similarity of the word embeddings of the Ectits is then calculated with respect to this average vector. This calculates the semantic similarity of the review collection with respect to the current review. If the similarity is high, it is assumed that the content is semantically close to the previous Ectits collection, and if it is low, it is considered that the content is semantically far from the previous Ectits collection. Since cosine similarity is used, the range of values is between 0 and 1.

C. Weighted sum of importance and novelty

The weighted sum of A and B above is calculated in order to give a higher evaluation value to words that have a higher importance and have a different meaning from the previous eclectic set.

MMR(s) = λ A - (1-λ)B

[IMPACT] How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

The development of this model will build a token economy in an economic activity similar to the real economy, coffee. The specific construction of this model, in conjunction with the development services to be submitted in a separate category, will have the following benefits.

1. Feasibility plan in Colombia; a local partner has already been found with the support of JICA and the Colombian government. Plans are underway to provide services for coffee consumption generated by 300 major coffee shops; a site visit will be conducted in August, and full operation is planned to begin in 2024.
2. the creation of carbon credits through coffee resource recycling, which will be submitted in a separate category, will allow us to take action on climate change issues to the extent that the number of users increase
3. Coffee producers and baristas, especially in Africa and Latin America, will be able to receive tokens through coffee consumption.

These solutions are directly related to Cardano's philosophy and will be a great benefit to the ecosystem.

This proposal is an important step in preparation for that.

[IMPACT] How do you intend to measure the success of your project?

While project success is measured by actual development and the number of Ecrits responses, effectiveness is measured in the short and long term on two axes: economic and well being.

1.economic measurement

Short term: we have at least 3700/month converting customers and have already given back to the producers by providing over 30000 cups of coffee.

https://qoffee.jp/

Long term: If this project is released, it will create an unprecedented sustainable circular economy model. The keyword "regenerative" has been attracting attention in recent years as a further action for sustainability, and this project will serve as a role model for a regenerative economy.

2.Well being

Short-term: We conducted a survey of 5 users, and 54 users responded that the number of keywords for taste would increase.

Long term: According to our own survey of 3,500 people, data shows that approximately 60% of people do not know their own taste preferences.

We know that there is a correlation between language and taste.

In addition, according to a joint research with our co-proposer Mr. Yamanishi, there is a large discrepancy between the verbalization of taste between ordinary consumers and professional baristas.

Based on the above, it is expected that the matching of taste and preference through this project will have a significant effect on well being.

3.Why it's a benefits for Cardano

We plan to implement these contents and exhibit and demonstrate them at the Osaka-Kansai Japan Expo. Needless to say, we will contribute to the Cardano ecosystem.

[IMPACT] Please describe your plans to share the outputs and results of your project?

We plan to use three approaches to reporting.

• Submitting monthly and milestone reports
• Reporting at the Eastern town hall meetup
• Reporting at the Cardano Community Booth in Japan

We have reported at the Eastern town hall and Cardano booth for Catalyst 9, and we will be able to do so again without any problems.

[CAPABILITY/ FEASIBILITY] What are the main goals for the project and how will you validate if your approach is feasible?

”Consuming to Regenerative a platform”

Value_way is a project in which consumers proactively commit themselves to environmental contributions by "recording their coffee consumption.

The value chain from coffee producing countries to consumption and beyond to carbon offsetting is recorded in a blockchain. Through coffee consumption activities that are familiar to our daily lives, we aim to change the behavior of society as a whole by making consumers the link between production, which is at the top of the chain, and resource recycling, which is at the bottom.

[RESOURCES & VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

Coffee the most familiar drink in our daily lives, consumption is increasing year by year, and it is also the second largest international trade in value after oil in the world market. If Cardano were to take on the task of solving the Coffee 2050 problem and the traceability of the coffee trade, it would not only increase Cardano's social recognition and market value, but would also reduce greenhouse gas emissions, bringing it closer to solving the environmental problem.

[IMPORTANT NOTE] The Applicant agreed to Fund10 rules and also that data in the Submission Form and other data provided by the project team during the course of the project will be publicly available.
