Course Discription |
:
In this course, you will learn the underlying technologies of these and other powerful tools for accessing and mining text information. You will be able to learn the basic principles and algorithms for information retrieval. Unlike structured data, which is typically managed with a relational database, textual information is unstructured and poses special challenges due to the difficulty in precisely understanding natural language and users' information needs. In this course, we will introduce a variety of techniques for accessing and mining text information. The course emphasizes basic principles and practically useful algorithms. Topics to be covered include, among others, text processing, inverted indexes, retrieval models (e.g., vector space and probabilistic models), Information Retrieval evaluation, text categorization, retrieval system design and implementation, issues of web search engines, and applications of text retrieval and mining. |
