  1. The practice of assigning multiple taxonomy terms to a single document to represent all its significant topics is called:

    Answer: Exhaustivity indexing

    Exhaustivity refers to the depth of indexing—assigning all relevant terms to a document so it can be retrieved under each of its topics.

  2. A metadata element that uniquely identifies a resource and remains stable even if the resource is moved is called a:

    Answer: Persistent Identifier (PID)

    Persistent Identifiers (e.g., DOI, ARK, PURL) are designed to remain stable and resolvable over time regardless of the resource's location.

  3. In RDF (Resource Description Framework), the basic unit of information is a triple composed of:

    Answer: Subject, predicate, and object

    An RDF triple consists of a subject (resource), a predicate (property/relationship), and an object (value or another resource), forming a machine-readable statement.

  4. Which scenario represents a 'false drop' problem in taxonomy-based retrieval?

    Answer: A document on 'Java programming' is retrieved because the term 'Java' is also used for the Indonesian island

    A false drop occurs when an ambiguous term retrieves irrelevant documents; controlled vocabulary with scope notes or disambiguation prevents this.

  5. The process of automatically suggesting taxonomy terms for a document based on its content using NLP is known as:

    Answer: Auto-classification

    Auto-classification uses natural language processing and machine learning to propose or assign controlled vocabulary terms to documents without manual effort.

  6. When designing a metadata schema, 'repeatability' of an element means that:

    Answer: A single record can contain multiple values for that element

    A repeatable element allows a record to carry multiple values (e.g., multiple Creator names), accommodating real-world complexity in resource description.

  7. In taxonomy design, the 'specificity' principle states that indexing terms should be:

    Answer: As specific as the content warrants, using the most precise applicable term

    Specificity means assigning the most precise term that accurately describes the concept, improving precision in retrieval without sacrificing appropriate recall.
