Search Engines (SE)

Course content

The course objective is to offer an advanced introduction into search engines. The goal is to understand and model how search engines collect information, transform it and store it internally, and then operate on it in order to satisfy user queries. Through realistic and sound projects, the course aims to stimulate and prepare students for their MSc thesis work.

 

The course will focus on these main questions:

  • How can we design efficient retrieval systems?
  • How can we design effective retrieval systems?

 

Content in detail:

Architecture of an IR system

  • Basic building blocks
  • Crawling, filtering and storing information
  • Ranking with indexes

 

Information ranking models

  • Probabilistic & machine learning models
  • Complex queries and combining evidence
  • Deep learning for search engines
  • Evaluation and optimisation

 

Education

MSc Programme in Computer Science

Learning outcome

Knowledge of

  • The basic architecture of search engines
  • The basic models and techniques for collecting, storing and ranking information
  • Different criteria for search engine evaluation

 

Skills in

Students should be able to transfer the above knowledge to real-world tasks by:

  • Designing appropriate strategies for crawling, storing and ranking information
  • Planning and carrying out appropriate evaluations

 

Given a working search engine, students should be able to:

  • Diagnose problems in its main information processing functions
  • Design and calibrate appropriate solutions

 

Competences to

  • Explain the basic search engine principles to both laymen and specialists
  • Use standard procedures and practices when designing or implementing search engine solutions
  • Present evaluation analyses and results in a proper format of a written report such that a technically qualified person can follow and obtain similar findings

 

The course will use a combination of lectures (2 hours per week) and lab sessions (2 hours per week). Lectures and labs might include discussions, group activities, and student presentations. Where possible, relevant guest lecturers will be involved.

Students will carry-out a project which consists of both practical exercises (implementing state of the art solutions) and theoretical questions (to reflect on the course content in relation to the project). The project will cover the main topics presented during the lectures.

The literature consists of seminal research and review articles from central journals and selected papers from peer-reviewed conferences, textbooks and research reports. This is supplemented with practical experience gained through lab sessions.

The literature will be listed in Absalon.

It is expected that students know how to program and have a working knowledge of Machine Learning corresponding to the course Machine Learning (ML) or an equivalent course.

Academic qualifications equivalent to a BSc degree is recommended.

The course is identical to NDAK20002U Neural Information Retrieval

Oral
Feedback by final exam (In addition to the grade)
ECTS
7,5 ECTS
Type of assessment
Oral exam on basis of previous submission, 20 minutes (no preparation)
Type of assessment details
Specifically, the exam consists of two parts:

1. An individual report (written assignment) based on the project.
2. An individual oral examination (without preparation) based on the report.

The written and oral examination are not weighted. Only one overall assessment is provided for the two parts of the exam.
Aid
All aids allowed
Marking scale
7-point grading scale
Censorship form
No external censorship
Several internal examiners
Re-exam

Same as the ordinary exam.

For the re-exam the student must complete a new project and submit a new report. The deadline for submitting the new report will be published in Absalon.

Additionally the 20-minutes oral examination without preparation will be administered covering the full course syllabus.

The written and oral examination are not weighted. Only one overall assessment is provided for the two parts of the exam.

It is not possible to reuse parts of the exam at a later exam.
