Sample question 1 — Implement text analysis solutions
A biotech team must pull drug-trial identifiers and internal compound codes out of research abstracts. These terms are not recognized by the prebuilt entity types, and the team has a few hundred labeled examples. Which Language capability should the team use?
- A. Train a custom named entity recognition model on the labeled examples to extract the domain terms.
- B. Use the prebuilt entity recognition model and keep only the entities that look like trial identifiers.
- C. Train a custom text classification model on the abstracts to label each abstract by trial phase.
- D. Fine-tune a summarization model on the abstracts and read the identifiers out of each summary.
Answer: A. Option A is correct because a custom named entity recognition model learns the team's own entity types from labeled examples and extracts drug-trial identifiers and compound codes. Option B is incorrect because the prebuilt model does not know the team's private entity types, so filtering cannot recover them. Option C is incorrect because text classification labels the whole abstract and does not extract the identifiers. Option D is incorrect because a summary describes the abstract and does not reliably preserve exact codes.
