Abstract— Information retrieval involves finding some
required information in a collection of information or in
database. The collection not necessarily be in one language
only as information does not limited to language. The simplest
way to search for the information is to look at every item in the
collection and when the need to translate the languages being
used arises, this is where the techniques and methods that were
being developed for the cross-lingual retrieval system will take
place. This article reviews some recent researches focusing on
topics in cross-lingual information retrieval and their role in
current research directions in the wide area of information
retrieval.
