Definition of Information Retrieval System refers to

• Storing only structured data

• Managing relational databases

• Finding and retrieving information from large datasets

• Creating physical libraries

Primary objective of Information Retrieval Systems is to

• Store physical documents

• Provide efficient access to relevant information

• Replace databases

• Manage digital hardware

Information Retrieval Systems are closely related to

• Operating Systems

• Database Management Systems

• Image Processing Systems

• Circuit Design

The process of removing most common words (and, or, the, etc.) by an information retrieval system before indexing is known as

• Lemmatization

• Stop word removal

• Inverted indexing

• Normalization

Structured data is well defined data typically represented by:

• List

• Rows and Columns

• Rows

• None

The two major measures commonly associated with information systems are

• Precision and Recall

• Precision

• Recall

• Mean & Mode

A key search capability of Information Retrieval Systems is

• File Compression

• Document Ranking

• Data Encryption

• Image Processing

Browsing capabilities in Information Retrieval Systems allow

• Direct access to specific records

• Users to explore information in a structured manner

• Real-time data processing

• Only keyword-based searches

Indexing primarily helps in

• Reducing data size

• Enhancing the aesthetic of documents

• Improving search speed and efficiency

• Encrypting information

Stemming algorithms are used to

• Extract metadata

• Reduce words to their root form

• Index multimedia files

• Translate documents
