SIT/IRV Advanced Information Retrieval & Visualization<br />

ECTS-Credits: 6.0<br />

Summary: This module teaches methods, concepts, and techniques of Information Retrieval<br />

(IR) as well as Information Visualization (InfoVis) and Visual Analytics (VA) to<br />

deal with the problem of information overload. Information Retrieval enables managing<br />

large collections of unstructured text and multimedia content (such as typically found in<br />

digital libraries and the web) and extracting selective content relevant to users' current<br />

information needs. With ever-growing information repositories, fast and scalable retrieval<br />

systems are key in helping people to complete their information tasks eciently.<br />

Visualization can help to make sense of data (potentially returned by an IR engine), explore<br />

complex information spaces or spot patterns and relationships by taking advantage<br />

of the powerful human perceptual system that is extremely ecient in processing visual<br />

input,. Information Visualization is an interdisciplinary eld of research that is concerned<br />

with interactive visualizations of mainly abstract data and has its roots primarily in<br />

computer science. Interactivity or the possibility to engage in an active discourse with<br />

the representation lies at the core of Information Visualization. Visual Analytics extends<br />

InfoVis by integrating automated analysis methods (e.g., statistics, data mining,<br />

machine learning) and focusing on analytical reasoning supported by interactive visual<br />

interfaces.<br />

Learning Outcomes: The goal of this course is to gain in-depth knowledge about methods,<br />

concepts, and techniques of Information Retrieval, Information Visualization (InfoVis)<br />

and Visual Analytics. The students should be able to assess the quality of retrieval<br />

system performances, visual representations and gain skills for problem analysis, the<br />

design and implementation, as well as the evaluation of visualization systems.<br />

Knowledge:<br />

• Text processing and indexing (n-grams, Latent Semantic Indexing)<br />

• Retrieval models (probabilistic retrieval models (e.g. BM25,language models))<br />

• Evaluation of retrieval systems (measures, collections, system vs. user-based evaluation)<br />

• Information Extraction and Natural Language Processing<br />

• Interactive Information Retrieval and Information Retrieval Interfaces<br />
