Which search engine is the best?
1. Pick two search engines to compare such as Yahoo, Google, Bing, or DuckDuck Go.
Google and yahoo
2. Try lexically ambiguous searches, such as China or Washington. What search engine handles your search better? Why? Do you see any clustering?
I would say that google is more organized with its search engine. While Yahoo is more clustered and has useless information.
3. Try a sample search on both pages that is not (or is minimally) semantically ambigiuous. Considering only the top 20 results, which search engine offers better precision? Why do you say so?
I would still say that google because like I said in the previous question it is more organized with its information.
4. Is it possible to determine which search engine offers better recall? Explain why or why not?
Determining recall (the ability to return all relevant results) is more complex. It generally requires a known set of relevant results for comparison. Since this dataset isn’t available, it’s challenging to definitively measure recall for these search engines.
