This paper talks about a new way to help computers find information even when they haven't seen examples of similar searches before. This is called "zero-shot" information retrieval. The authors propose a system called Universal Document Linking (UDL) which connects similar documents to help the computer learn how to create new searches. UDL works by figuring out how similar documents are based on the words they use and then deciding whether to connect them based on how specialized the topic is. The authors found that UDL was able to improve the accuracy of computer searches in different situations, including different topics, languages, and types of searches. They also found that UDL was more efficient than other methods that require more computer power.
