The Society of Wilderness, SOW, is an environmental association which was founded by the general public in 1995. The organization is dedicated to make significant and selfless contribution to protect ecological environment in Taiwan through natural education, participation in environmental issue, habitat preservation, going deep into communities and promoting volunteer activities.
In terms of marine protection, SOW not only holds beach cleanups and environmental education activities, but also builds a platform in June 2015 to facilitate data collection and researchers on marine debris. The platform initiates Beach Litter Rapid Assessment around the island in 2018 and receive the first accurate data of the waste distribution along the coast of Taiwan. On the other hand, SOW has been working hard on promoting plastic reduction. By reducing the use of disposable products, we can help keep Taiwan coastline clean and beautiful.

Marine litter has become a critical pollution issue which is worthy of global attention. Scientific studies show that artificial waste has posed a tremendous and irreversible threat to our environment and economy.

Compared to air and water pollution, the geographic scale of marine waste is far more larger, which results in difficulties for finding the connection between the pollution source and polluted area.

There are high discrepancies in artificial waste in appearances, size, weights and ingredients, which makes it challenging to identify these pollutants with single detector or utilizing methods commonly used in examining heavy metals and pesticide.

Although the reduction of artificial waste is the fundamental way to solve the pollution issue, however, it’s challenging and time-consuming. Thus, terminal solutions such as beach cleanup have played an important role in alleviating this crisis.

Beach Litter Rapid Assessment allows researchers to conduct sampling survey in a wide range of locations in a short period of time. It is one of the examination methods that helps quantify the marine wastes and assist scientists decide the location where beach cleanup should be held. The sampling survey is conducted by each observation station every ten kilometers of the shoreline. Taiwan has 121 observation stations in the 2210-kilometer coastline.

This topic focuses on exploiting the data collected by one observatory to predict the sampling survey results of nearby observatories. This method is expected to lower the amount of observation station and the involvement of human labor.

Evaluation Criteria

After the participants uploaded their forecasts, the system will calculate the score based on Cohen’s kappa formula illustrated below:

$$ k=1- {\sum_{i=1}^{k} \sum_{j=1}^{k} w_{ij} x_{ij} \over \sum_{i=1}^{k} \sum_{j=1}^{k} w_{ij} m_{ij} } $$



  • The evaluation will be based on the final uploaded result. If multiple participants get the same evaluation scores, the time of uploading will determine the ranking.
  • The maximum number of uploading times is 2 times per day.
  • Using licensed external data sets is allowed. However, for equity, if external data sets are used, their instructions and references should be stated in the forum for references.
  • All the data, techniques and source codes are original work of participants or are used by permission complying with laws and regulations. If any third-party claims their intellectual property rights or other rights and interests are being violated, the participant will need to handle the disputes personally. If any participants violate intellectual property rights, they will be disqualified, and shall bear legal responsibilities.
  • All the achievements and their IPRs (intellectual property rights) belong to the participants, and the Copyright License Agreements, patent applications, technology transfer and equity distributions of them, should in accordance with the relevant Laws and Regulations.
  • This issue does not offer a team-up option, only one account per person is allowed and each person can only participate once. If any violations are found, people who are involved would be forced to withdraw the activity.
  • If there is cheating or fraud during the activity, such as exchanges and discussions between different accounts, the team that cheats will be disqualified from the activity and the vacancy would be filled up by other teams in the ranking order.
  • After uploading, the answers of test data would be divided into two parts to calculate the score:
    • Before the deadline of the activity: The system refers to only a part of the test data to examine and calculate the score. The result will be posted on Public Leaderboard as reference for the final score and ranking. This data accounts for 50% of the entire test data.
    • After the deadline of the activity: The system refers to the remaining test data (50%) to examine and calculate the score. The result will be posted on Private Leaderboard as reference for the final score and ranking.
  • For those who have signed up for this competition, you acknowledge that you have read, understood, and agreed to be bound by the terms and regulations of this activity.
  • Competitors who violate relevant terms or regulations will be disqualified from the activity. If the award has been given, the prize will be revoked, and the participants will need to return the prize money as well as certificate.
