In this paper, we propose a sieve filtering-based approach that can retrieve facts to invalidate claims made in social media posts. The fact filters are initially coarse-grained, based on the original language of the social media posts, and end with fine-grained filters based on the exact time frame in which the posts were uploaded online. This streamlined approach achieved a 0.883 retrieval success rate in the monolingual task while maintaining a scalable efficiency level of processing a social media post per 0.07 seconds.
