OSO.AI
$6,000 prize poolOso Track: Use AI to pull community data
$5,0001st $3,000 · 2nd $1,500 · 3rd $500
No winner listed
Prize details
Select this track if you're project is using AI to pull community data (projects, DAO, etc) and make it available in a data store. Staying up to date on all the projects you are invested or involved in is impossible with information fragmented across discord, telegram, twitter, forums, snapshot, and so on. OSO wants to make this easier by aggregating all of this information and being able to allow our users to query in natural language asking for specific updates and information right from their messenger (currently supports telegram). OSO also lets you select projects you want to receive updates on and delivers a daily digest of information from the projects you select. We are looking for the team / individual that can best pull this information from multiple sources, into a central store (Pinecone, Deeplake, SQL, other), where OSO can integrate this information and make it available to those users that hold interest in the project. This can be done using ReactJS preferred (or other web framework) where OSO can query the pages for data and use the resulting data. The more reliable the data and the easier it is for OSO to use the data the more points will be awarded. Bonuses: - For cleaned data, make the data consistent and machine readable - Data that has sentiment analysis included - Data that has been ingested into a vector store for easy use from our language models Possible Ideas: - Sentiment analysis of twitter/discord for a specific project - Intake process to make it streamlined for any project/community to add their data sources to OSO. ie React page that allows projects to add their RSS or other feeds. - Integrating specific communities/projects/tokens and channels from multiple sources which can then be queried by the end user in OSO or pushed in a daily update. How to Start: OSO utilizes a custom AI agent framework that preprocesses queries to determine task vs informational items. The framework is written in python and runs in an AWS serverless environment. OSO uses ReactJS pages to interface with outside API's, present information to our users in a mobile web friendly format, etc. As an example, pages have been included for reference which shows our DAO governance processing. - Identify a matrix of sources for projects - Identify methods of querying the sources - Identify a storage method for the data - Process the data (clean, sort, sentiment, etc) - Respond to query with data and details

We are looking for the team / individual that can integrate image creation through API calls, and taking the finished image and minting it all from within the OSO app. This can be done using ReactJS preferred (or other web framework) where the OSO user can activate the NFT generation as a call to the React pages. **How to Start:** OSO utilizes a custom AI agent framework that preprocesses queries to determine task vs informational items.
