Abstract
From the user perspective, Information Access is a cognitive process that involves more than the retrieval of a set of documents. Depending on the kind of information need, the sources of information, their size, media, etc. users must develop different strategies to find the information, explore and finally process it in order to group related pieces, synthesize pertinent information, discover trends, etc. All these tasks share something in common: the need to give structure to information. This is the general goal of Information Extraction. At the same time, all these tasks have to deal with language barriers like domain specific vocabularies or languages not known by the user.
Terminology Extraction also provides some basic techniques useful for these challenges in Multilingual Information Access. The lecture will discuss these issues and study some research and evaluation frameworks related to Information Access tasks that need some kind of Information Extraction.
