Question 150

A defect-report dashboard already receives key phrases such as “battery hot,” “overheating battery” and “loose hinge.” It must count recurring issues without confusing the battery and hinge faults. What should the next text-analysis step do?

  1. Normalize and group equivalent source-backed defect phrases, retain the original phrase and report references, and count each issue separately.
  2. Combine all negative phrases into one “unhappy customer” group without retaining which component failed.
  3. Use only organization-name recognition and discard extracted component-fault phrases.
  4. Generate a fresh defect category for every paraphrase so “battery hot” and “overheating battery” are always different issues.

Explanation

Correct Answer

A:

The phrases already exist; the next task is to group synonymous battery complaints while keeping hinge defects separate. Source references allow dashboard counts to be audited against real reports.

Incorrect Answers

B:

Sentiment grouping loses which physical component needs investigation. Battery overheating and hinge looseness require different engineering responses even if both customers are unhappy.

C:

Entity detection may identify vendors or product models but does not by itself normalize the concrete failure descriptions the dashboard is trying to count.

D:

Treating paraphrases as unrelated categories overstates the number of distinct faults. A controlled normalization step should group equivalent wording without erasing source evidence.

Question 151

An internal contract parser must identify the parties "Aster Systems" and "Jordan Lee" while excluding ordinary words that merely resemble names. What text technique is appropriate?

  1. Extracting the longest phrase on each page as the company name.
  2. Summarizing the contract without preserving name spans or entity roles.
  3. Named-entity recognition with contextual validation of organization and person labels.
  4. Sentiment classification that labels each clause positive or negative.

Explanation

Correct Answer

C:

Named-entity recognition can label the candidate organization and person while nearby signature and party clauses validate their roles. Preserve document spans so the two names are distinguished from ordinary capitalized terms.

Incorrect Answers

A:

The longest phrase could be a liability clause rather than a contracting party. Phrase length does not establish whether Aster Systems is an organization or Jordan Lee a person with a named legal role.

B:

A prose synopsis can omit an exact company name or paraphrase a person, losing the source span needed for contract-party verification. The workflow needs typed identities, not an overall summary.

D:

Sentiment labels evaluate positive or negative language, which is not evidence of who signed or is a party to the contract. Legal identity extraction must follow entity types and context.

Question 152

A marketing study requires each customer review to be labeled positive, neutral or negative without inventing an additional label. Which design is appropriate?

  1. Topic modeling with a fresh cluster name invented for every individual review.
  2. Sentiment classification against the defined label set and annotated validation examples.
  3. Text generation that returns a long summary but omits all sentiment labels.
  4. Named-entity extraction that treats every product reference as positive sentiment.

Explanation

Correct Answer

B:

A bounded sentiment classifier assigns one permitted polarity and can be tested on annotated reviews. Evaluate ambiguous, mixed and negated examples before treating its output as a comparable marketing metric.

Incorrect Answers

A:

Topic modeling groups reviews by subjects such as delivery or battery; a per-review topic cluster does not encode positive, neutral or negative attitude and can break the fixed downstream label vocabulary.

C:

A long narrative could mention what customers said, but it does not provide the required machine-readable three-way sentiment label for aggregation. Response length is irrelevant to taxonomy compliance.

D:

A product reference is an entity or aspect, not an opinion. A negative review can mention a brand repeatedly, and mapping any mention to positive creates systematic false positives.

Question 153

A support manager needs a short summary of a 20-message dispute. One message says a replacement was only promised, not shipped. What should the summarizer preserve?

  1. The distinction between a proposed replacement and a confirmed shipment, linked to the source messages.
  2. A fluent statement that the item has already shipped because doing so makes the summary concise.
  3. Summarize only the initial complaint and final reply, omitting the intervening promise that replacement shipment remained pending.
  4. A sentiment label instead of a chronology or status summary.

Explanation

Correct Answer

A:

A useful dispute summary must distinguish the agent promising a replacement from the fulfillment service actually shipping it. Citing the relevant messages allows the case owner to verify that the outstanding action remains open.

Incorrect Answers

B:

Claiming shipment from a promise transforms an intention into a completed transaction. The thread has no carrier confirmation or dispatch record, so this attractive concise wording is materially false.

C:

A two-message summary can be concise but may erase the exact unresolved service commitment. The manager needs the source-linked distinction between a promise and fulfillment.

D:

A positive or negative polarity label cannot tell the support manager whether a replacement is pending or dispatched. The requested deliverable is a factual sequence and current case state.

Question 154

A mailbox triage service needs to recognize exact order identifiers embedded within complaint prose and verify them against the commerce system. What extraction step is necessary?

  1. Select the longest number in the message as the order ID without validation.
  2. Extract candidate IDs using a validated pattern or domain entity model, then check their format and existence.
  3. Generate a new order number when a message includes only a partial reference.
  4. Use generic sentiment analysis to infer the order number from customer frustration.

Explanation

Correct Answer

B:

Pattern- or domain-aware extraction identifies a candidate identifier; a format check and authorized commerce lookup establish whether it exists and belongs to the caller. Candidate text alone must not be treated as a verified order.

Incorrect Answers

A:

Messages can contain dates, amounts, phone numbers or tracking IDs longer than the actual order number. Selecting by digit count creates false joins and can expose unrelated customer transactions.

C:

A plausible generated reference is not a source-system identifier. Inventing digits for an incomplete customer reference risks showing staff the wrong order or recording changes against another purchase.

D:

Customer frustration may tell support how to prioritize a reply, but sentiment contains no deterministic order number. Identification must be grounded in the text and validated by the commerce system.

Question 155

A sentiment classifier treats the sentence "The device is not bad" as strongly negative because it matches the word "bad." What must be improved?

  1. Evaluate and use context-sensitive sentiment handling that accounts for negation.
  2. Add more weight to isolated negative keywords, including "bad."
  3. Extract "device" as a named entity and use that type as the sentiment.
  4. Strip stop words such as "not" before predicting sentiment.

Explanation

Correct Answer

A:

Negation changes the scope of the adjective: “not bad” often carries neutral-to-positive rather than strongly negative sentiment. Use contextual language analysis and validate on expressions with different negation patterns.

Incorrect Answers

B:

Adding weight to “bad” amplifies the incorrect lexical shortcut demonstrated by the sentence. The score would become more negative even though the phrase modifies that word with “not”.

C:

Extracting “device” identifies what is being discussed but not how the user feels about it. A noun’s presence cannot resolve the negated opinion clause.

D:

Treating “not” as an unimportant stop word destroys the token that reverses the sentiment. Preprocessing must preserve polarity cues rather than discard them indiscriminately.

Question 156

A customer writes "Fantastic, another three days without service" after an outage. The sentiment service predicts positive because it sees "fantastic." Select TWO appropriate improvements.

  1. Use a positive-word lexicon that scores the word 'fantastic' in isolation without examining the rest of the complaint or the outage context.
  2. Trust the positive prediction because "fantastic" appears at the start.
  3. Use the full utterance and incident context to assess implied negative sentiment.
  4. Include sarcastic and negated complaints in a labeled evaluation set and inspect classification errors.
  5. Delete all outage references before classification.

Explanation

Correct Answers

C:

The full utterance and known outage context make the apparent praise incongruent with the customer’s situation. Context-aware interpretation should treat the service-loss complaint as a likely negative experience.

D:

A labeled evaluation set with sarcastic and negated complaints tests the exact observed failure mode. Inspecting errors by construction reveals whether an updated model handles ironic language beyond keyword polarity.

Incorrect Answers

A:

A single positive term may be used sarcastically, and isolated word polarity does not capture the complaint that service was unavailable for three more days. Context-aware sentiment and difficult labeled examples are required.

B:

“Fantastic” is an isolated positive token, but “another three days without service” is evidence of dissatisfaction. A classifier relying on the first adjective will misclassify sarcastic failures.

E:

Deleting the downtime clause removes the evidence that the phrase is ironic. The remaining “Fantastic” is more likely to reinforce the incorrect positive prediction.

Question 157

A case note names "Alex Morgan" and later "Morgan Holdings". A parser merges them into one person entity. What validation is needed?

  1. Use local linguistic context and entity type disambiguation before linking the mentions.
  2. Merge every matching surname into the first person record encountered.
  3. Use the longest mention as the canonical person and relabel shorter mentions.
  4. Discard surrounding verbs and titles to simplify entity linking.

Explanation

Correct Answer

A:

“Alex Morgan” is used as a personal name while “Morgan Holdings” appears as an organization. Contextual labels, titles and nearby predicates can separate entity types before an entity-linker chooses canonical identities.

Incorrect Answers

B:

The shared surname does not prove the person owns or is identical to the company. Blind merging would corrupt two different legal-entity records and could misattribute contract actions.

C:

Choosing whichever mention has more characters still cannot distinguish a person from a corporation. Canonicalization must use type-compatible reference records, not string length.

D:

Surrounding words such as “works for,” “incorporated” or a signatory title provide evidence for roles and types. Discarding them makes the two mentions more ambiguous, not less.

Question 158

A manufacturer uses the term "Aurora" for a specific product line, while a generic entity extractor labels it as a person's name. Which correction addresses the business requirement?

  1. Use domain-aware entity definitions and representative validation examples for product identifiers.
  2. Use a title-case heuristic to force unknown capitalized tokens into the person category even when product records are present.
  3. Retrain only on general-purpose person/organization names without labeling manufacturer product examples or using catalog context.
  4. Override “Aurora” to the organization category because a company sells it, without checking whether the sentence refers to the product.

Explanation

Correct Answer

A:

If “Aurora” is an official product line, the entity catalog and labeled in-domain examples should recognize that business meaning. Evaluation must check the product label against surrounding inventory and catalog descriptions.

Incorrect Answers

B:

Capital letters are shared by people, locations and named products. A casing rule cannot reflect the manufacturer’s “Aurora” product-line identity.

C:

A generic training set may repeat the same product-to-person ambiguity. In-domain labeled entities and a governed catalog are the evidence needed for this specialized product.

D:

A product line is not itself the supplier’s corporate identity. This override merely changes the wrong entity type and can corrupt product-line aggregation.

Question 159

A news extractor returns "Seattle" as a geographic entity in a source sentence. Before saving it as the city of an incident, what must be checked?

  1. Validate the location type and sentence role against the original source span.
  2. Save every place name as the same city field without source-role checks.
  3. Use the first geographic entity in the document as the incident city.
  4. Accept the entity confidence score as proof of its role in the event.

Explanation

Correct Answer

A:

A location entity only establishes that Seattle was mentioned. The source may say the suspect traveled from Seattle or the victim lives there; validate the city’s role in the event clause before assigning the incident-city field.

Incorrect Answers

B:

Different places in one article can refer to publication, headquarters, travel routes and event sites. Treating every place name as incident location would merge incompatible roles.

C:

The first place name may be in an author byline or unrelated background sentence. Document order cannot reliably determine where the incident occurred.

D:

Entity confidence indicates how likely a span is a geographic name, not its semantic relation to the incident. Role extraction and original sentence context remain necessary.

Question 160

A summarizer produces an otherwise accurate refund-policy summary but omits a clause excluding purchases made after the promotion expired. What acceptance criterion is missing?

  1. Optimize summary lexical-overlap metrics and compress the response further without checking excluded purchase dates.
  2. Check material condition and exception coverage against the controlling source sections.
  3. Check whether the word “refund” appears in both texts and treat that as proof the expiration clause was preserved.
  4. Judge the summary only on fluency and shortness, without comparing the eligibility decision to the controlling policy.

Explanation

Correct Answer

B:

The release check must compare the summary with controlling policy conditions, dates and exceptions. In this scenario, missing the expired-promotion clause can incorrectly promise refunds to ineligible purchasers.

Incorrect Answers

A:

A summary can share most words with the source yet omit the one eligibility exclusion that changes the outcome. Overlap and brevity cannot substitute for clause-level factual coverage.

C:

Topic-word presence establishes the summary subject, not the expiry condition. The model must preserve the policy clause restricting purchases after promotion expiry.

D:

A fluent concise summary may still authorize an ineligible purchase by dropping a material exception. Source-grounded acceptance must cover dates and qualifications.
