Workshop on

INFORMATION RETRIEVAL AND WEB SEARCH

1st - 4th February, 2010

Organized by

Open and Distance Learning Centre at
The Faculty of Electrical Engineering and Information Technologies
and
TIME.mk Education

FINISHED !!!


Description

Information retrieval (IR) is the science of searching for documents, for information within documents as well as that of searching relational databases and the World Wide Web. IR is interdisciplinary, based on computer science, mathematics, library science, linguistics and statistics. Automated information retrieval systems are used to reduce what has been called "information overload".

This workshop will cover traditional material as well as recent advances in IR, the study of the processing, indexing, querying, organization, and classification of textual documents, including hypertext documents available on the World Wide Web. Practical working code examples will be shown that demonstrate some of the presented ideas.

Prerequisite:
Basic knowledge of data structures, algorithms and probability.

Language:
All materials (slides, codes, etc.) will be provided in English language but the lectures will be taught in Macedonian language.

Learning outcomes:
On completion of this workshop, you should be able to:
  1. Build complete IR system from scratch.
  2. Build simple web search engine (crawler, indexing, ranking).
  3. Apply different machine learning techniques (classification, clustering, etc.) on text documents.

Lecturer

Dr. Igor Trajkovski graduated from the Institute of Informatics, Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius University - Skopje, in 2001. In 2004 he obtained Master of Computer Science at Max Planck Institute for Informatics, Saarbrucken, Germany. His studies and research work has continued on Jozef Stefan Institute in Ljubljana, Slovenia in the Department of Knowledge Technologies, where in 2007 gains the academic title Doctor of Sciences. In 2007-2008 he worked for Google (Mountain View, California, USA and Zurich, Switcerland) as software engineer and software engineer in testing. He is the founder of the Macedonian and Slovenian news aggregators TIME.mk and TIMES.si and TIME.mk's branch for life-long continuous education, TIME.mk Education. His research interests include: Statistical Natural Language Processing, Machine Learning, Advanced Algorithms and Data Structures, Parallel Algorithms, Bioinformatics.
