Information Retrieval - Syllabus

An overview of computers and their significance in today's world. This topic sets the stage for understanding the basics of computers.

Understanding the difference between digital and analog computers, their characteristics, and applications.

Exploring the key characteristics of computers, including input, processing, storage, and output.

A brief history of computers, from their inception to the present day, highlighting key milestones and developments.

Understanding the different generations of computers, including their features, advantages, and limitations.

Categorizing computers based on their size, functionality, and application, including desktops, laptops, and mobile devices.

Overview of information retrieval models and their significance in IR systems.

Categorization of information retrieval models and their relationships.

The process of retrieving and ranking documents based on relevance to a query.

Mathematical representation of IR models and their underlying assumptions.

A model that retrieves documents based on exact matching of query terms.

A model that represents documents and queries as vectors in a high-dimensional space.

A model that estimates the probability of a document being relevant to a query.

Memory Read operation involves retrieving data from memory locations. It is a fundamental operation in microprocessor-based systems.

Memory Write operation involves storing data in memory locations. It is a crucial operation in microprocessor-based systems.

I/O Read operation involves retrieving data from input/output devices. It enables the microprocessor to interact with the external environment.

I/O Write operation involves sending data to input/output devices. It enables the microprocessor to interact with the external environment.

Direct Memory Access (DMA) is a technique that allows peripheral devices to access system memory directly, reducing the microprocessor's workload.

An interrupt is a signal to the microprocessor that an event has occurred, requiring immediate attention. It enables the microprocessor to handle asynchronous events.

There are different types of interrupts, including maskable and non-maskable interrupts, which vary in their priority and handling by the microprocessor.

Interrupt Masking is a technique that enables the microprocessor to temporarily ignore or mask interrupts, allowing it to focus on high-priority tasks.

Non-overlapping lists are used in some retrieval models to improve the efficiency of retrieval by reducing the number of documents to be ranked.

The proximal nodes mode is a retrieval model that uses the proximity of terms in a document to improve the retrieval of relevant documents.

Understanding flashback technology, including performing flashback on Container Database (CDB) and Pluggable Database (PDB).

Concept of query processing, including the steps involved in processing a query and the role of the query processor.

Query trees and heuristics for query optimization, including the use of query trees to represent queries and heuristics to guide optimization.

Choice of query execution plans, including the factors that influence the choice of plan and the importance of plan selection.

Cost-based optimization, including the use of cost estimates to guide optimization and the role of cost-based optimization in query processing.
