We’ve fundamentally transformed Facebook Groups Search to help people more reliably discover, sort through, and validate community content that’s most relevant to them.
We’ve adopted a new hybrid retrieval architecture and implemented automated model-based evaluation to address the major friction points people experience when searching community content.
Under this new framework, we’ve made tangible improvements in search engagement and relevance, with no increase in error rates.
People around the world rely on Facebook Groups every day to discover valuable information. The user journey is not always easy due to the amount of information available. As we help connect people across shared interests, it’s also important to engineer a path through the vast array of conversations to surface as precisely as possible the content a person is looking for. We published a paper that discusses how we address this by re-architecting Facebook Group Scoped Search. By moving beyond traditional keyword matching to a hybrid retrieval architecture and implementing automated model-based evaluation, we are fundamentally innovating how people discover, consume, and validate community content.
