Σύνοψη	Multilingual topic modeling extends probabilistic topic models such as LDA to corpora spanning two or more languages, inferring shared latent topics across language boundaries. By tying topic distributions across languages, it enables cross-lingual document analysis, comparable topic discovery, and information retrieval without requiring full parallel corpora.	Multilingual sentence embeddings map sentences from many languages into a single shared vector space so that semantically equivalent sentences — regardless of language — land close together. Models such as LaBSE, multilingual Sentence-BERT, and mUSE have made it practical to compare, retrieve, and classify text across 50 to 100+ languages without translating anything first.
