Exam technique

Try to understand the high-level knowledge behind the timeline/evolution rather than the specifics highlighted below.

Early Machine Translation

The earliest attempts at machine translation date back to the 1950s.
These systems relied on rule-based approaches, where linguists manually created dictionaries and grammar rules for translation.

Note

Rule-Based Machine Translation (RBMT)
- These systems used bilingual dictionaries and syntactic rules to translate text.
- They were limited by the need for extensive manual labor and struggled with idiomatic expressions and complex sentence structures.

Statistical Machine Translation (SMT)

In the 1990s, Statistical Machine Translation (SMT) emerged as a breakthrough in the field.
SMT systems used large parallel corpora (collections of texts in multiple languages) to learn translation patterns.

Example

IBM Model 1
- One of the earliest SMT models, IBM Model 1, used word alignment techniques to map words in the source language to their counterparts in the target language.
- This approach improved translation quality but still struggled with context and fluency.
