Soru Cevap Sınavı

Testi çözdüğünüzde cevaplar ve açıklamalar görünür.

1. Çıkarıcı soru cevaplama sistemi ne yapar?
   • Soruyu yanıtlayan bir pasajdaki metnin tam aralığını seçer
   • Kendi sözleriyle yepyeni bir cevap yazıyor
   • Soruyu başka bir dile çevirir
   • Web sayfalarını popülerliğe göre sıralar
2. What evidence-access distinction separates closed-book QA from an open-book QA setting?
   • Open-book systems are forbidden to read documents
   • Closed-book systems must always be more accurate
   • Closed-book uses model parameters without external lookup; open-book can use supplied or retrieved documents
   • Open-book systems cannot include a language model
3. How can retrieval-augmented generation support a QA answer?
   • By guaranteeing every retrieved passage is correct
   • By eliminating the need to interpret any passage
   • By automatically proving every output claim true
   • By providing retrieved passages as evidence for generation
4. Which boundary scores can an extractive QA head produce when selecting an answer span?
   • Only a translation score for French output
   • Scores for possible answer-start and answer-end positions
   • Only a grammatical noun-or-verb label
   • Only the alphabetical rank of each word
5. Pasajda cevap yoksa, iyi tasarlanmış bir QA sisteminin işareti nedir?
   • Zaten akla yatkın görünen bir cevap icat ediyor
   • Tüm pasajı döndürür
   • Sorunun cevaplanamaz olduğunu kabul ediyor ve öyle diyor
   • Çöküyor
6. How does generative QA differ from requiring an extractive source span?
   • It produces answer text rather than requiring an exact span from the passage
   • It is restricted to one yes-or-no label in every task
   • It never outputs any words present in a source
   • It must output only a highlighted passage boundary
7. In SQuAD-style QA evaluation, what can token-overlap F1 provide that exact match alone does not?
   • Proof that every claimed fact is true
   • Partial credit for answer words overlapping a reference
   • A guarantee that no answer was copied
   • The measured power usage of a server
8. Why evaluate a QA system on paraphrased questions that preserve the intended meaning?
   • To guarantee that every new paraphrase has a different answer
   • To remove all passage evidence from every evaluation
   • To replace answer quality with filename length
   • To test sensitivity to changes in question wording
