CDIA Indexing & Metadata Management 1 — Questions and Answers
Question 1: In document imaging, what is the primary purpose of indexing?
- To compress document file sizes
- To enable fast and accurate document retrieval (Correct answer)
- To encrypt documents for security
- To convert paper documents to digital format
Correct answer: To enable fast and accurate document retrieval
Indexing creates searchable attributes or tags associated with a document so users can quickly locate and retrieve it.
Question 2: Which type of indexing assigns predefined category values from a fixed list to a document field?
- Full-text indexing
- Free-form indexing
- Controlled vocabulary indexing (Correct answer)
- Semantic indexing
Correct answer: Controlled vocabulary indexing
Controlled vocabulary indexing uses a predetermined set of acceptable values for index fields, ensuring consistency across the document repository.
Question 3: What is full-text indexing in a document management system?
- Indexing only the document title and author
- Indexing every word within the document content for search (Correct answer)
- Indexing documents by file size and date only
- Indexing documents using barcodes embedded in pages
Correct answer: Indexing every word within the document content for search
Full-text indexing captures and indexes every word in a document's content, enabling keyword searches across the entire body of stored documents.
Question 4: What is the role of OCR (Optical Character Recognition) in document indexing?
- It compresses scanned images for storage
- It converts scanned image text into machine-readable characters for indexing (Correct answer)
- It automatically routes documents to the correct folder
- It encrypts document metadata to prevent unauthorized access
Correct answer: It converts scanned image text into machine-readable characters for indexing
OCR converts raster text images into machine-readable text, enabling full-text search and automated metadata extraction from scanned documents.
Question 5: Which metadata standard, developed by the Dublin Core Metadata Initiative, provides 15 core elements for describing digital resources?
- EXIF
- IPTC
- Dublin Core (Correct answer)
- XMP
Correct answer: Dublin Core
Dublin Core is a widely adopted metadata standard offering 15 simple, interoperable elements (e.g., title, creator, date) for describing digital resources.
Question 6: What is a document index field?
- A physical folder label on a filing cabinet
- A specific attribute or data element used to identify and retrieve a document (Correct answer)
- A type of file format for scanned documents
- A compression algorithm applied during scanning
Correct answer: A specific attribute or data element used to identify and retrieve a document
An index field is a named attribute (e.g., invoice number, date, vendor name) assigned to a document to enable targeted searching and retrieval.
Question 7: What is zone OCR in the context of document indexing?
- OCR applied to the entire page simultaneously
- OCR that extracts text from predefined regions of a document page (Correct answer)
- A method of encoding barcodes into document zones
- An encryption process for securing scanned document regions
Correct answer: OCR that extracts text from predefined regions of a document page
Zone OCR targets specific, predefined areas of a document (such as a header or form field) to extract index data, improving accuracy and speed over full-page OCR.
