Cross-lingual Entity Typing (CLET) aims at improving the quality of entity type prediction by transferring semantic knowledge learned from rich-resourced languages to low-resourced languages. In this paper, by utilizing multilingual transfer learning via the mixture-of-experts approach, our model dynamically capture the relationship between target language and each source language, and effectively generalize to predict types of unseen entities in new languages. Extensive experiments on

We questioned the relationship between language similarity and the performance of CLET. With a series of experiments, we refute the commonsense that the more source the better, and propose the Similarity Hypothesis for CLET.
