Information Conservation & Retrieval

What are the different data storage methods?

• Graph databases

• XML databases

• Relational databases, NoSQL databases, file systems, cloud storage, in-memory databases

• Blockchain

Explain the concept of primary storage.

• Primary storage is the storage area in a computer where data is stored temporarily for quick access by the processor.

• Primary storage is only used for storing software applications.

• Primary storage is a type of external storage device.

• Primary storage is where data is permanently stored in a computer.

What is the purpose of secondary storage?

• The purpose of secondary storage is to store data for the long term, even when the power is turned off.

• Secondary storage is primarily used for storing software applications.

• The purpose of secondary storage is to speed up the computer's processing.

• Secondary storage is used for temporary data storage only.

Discuss the role of tertiary storage in data storage.

• Tertiary storage has limited capacity and is expensive compared to primary storage.

• Tertiary storage is primarily used for real-time data processing.

• Tertiary storage provides a cost-effective solution for long-term data retention, offering high capacity at a lower cost per gigabyte for storing large volumes of data that are accessed infrequently.

• Tertiary storage is designed for frequently accessed data to ensure fast retrieval.

How does cloud storage work?

• Cloud storage involves storing data on local servers.

• Cloud storage requires physical storage devices to access data.

• Cloud storage is only accessible through direct cable connections.

• Cloud storage involves storing data on remote servers accessed through the internet.

What are the common information retrieval techniques?

• Semantic analysis

• Boolean search

• Pattern recognition

• Keyword search, natural language processing, relevance feedback, query expansion

Explain the process of keyword-based retrieval.

• Keyword-based retrieval is a method that relies on audio files instead of text documents.

• Keyword-based retrieval involves indexing documents with keywords, matching user queries to these keywords, and retrieving relevant documents based on the keyword matches.

• Keyword-based retrieval is a process of physically retrieving keywords from documents.

• Keyword-based retrieval involves matching user queries to images instead of keywords.

Discuss the importance of relevance feedback in information retrieval.

• Relevance feedback does not impact search result accuracy

• Relevance feedback is not necessary in information retrieval

• Personalization is not a benefit of relevance feedback

• Relevance feedback in information retrieval is important for improving search result accuracy and personalization.

What is the role of clustering in information retrieval?

• Clustering is only useful for visualizing data and not for information retrieval.

• Clustering helps in summarizing information retrieved from the database.

• Clustering helps in organizing large amounts of data into meaningful clusters, making it easier to retrieve relevant information efficiently.

• Clustering is used to sort data alphabetically in information retrieval.

How does natural language processing aid in information retrieval?

• Natural language processing decreases search accuracy

• Natural language processing only works for written text

• Natural language processing enables systems to understand, interpret, and generate human language, improving search accuracy and relevance.

• Natural language processing has no impact on information retrieval
