- Tycho 11y agoWhen it is able to offer search suggestions or corrections to your search, I think some of that was based on machine learning on a massive corpus of text.
- omonra 11y agoI don't think so. I think it simply performs a spellcheck vs existing database of terms and offers a likely correction. Ie when you put in a word 'Mroscow' it sees that this term has 500 results while a similar term 'Moscow' has 100 million results. Therefore it assumes that you simply misspelled the word and offers the alternative as suggestion. It does not know what the actual underlying word means.

- dzhiurgis 11y agoPerhaps same way people associate facts? PageRank is one of the 200 metrics Google uses nowadays. It's weight is not as great before.
