Information Retrieval & Natural Language Processing
The site can be used for different purposes:
The course, in self-study modality requires between 40 and 80 hours of study, depending on how much time is devoted to open exercises and suggested readings. It is recommended to organize the study into 8 study weeks. To work as an independent learner you should be able to effectively organize your time. A Study Guide (in preparation) and Contacts are provided to support your study with this distance learning material.
- As a full course, to be followed in self-study modality
- As a source of material for practical work: examples and exercises
- As a repository of data and tools to perform NLP & IR tasks.
- As a virtual workspace to carry out small NLP&IR projects in collaboration

Syllabus topics (Description)Overview.
An introduction to the topic and a motivation to get into it.
A very basic review of the main issues and techniques related to the field of Information Retrieval.
Natural Language Processing for Information Retrieval.
A brief consideration of the potentialities of language technologies to improve text retrieval.
Cross Language Information Retrieval.
Cross-Language Information Retrieval, understood as a text retrieval problem where the query and the documents are expressed in different languages, is an area of research of growing importance that has brought language technologies to the attention of the text retrieval community. The greatest potential for Natural Language Processing in Information Retrieval seems to be here.
