A. Available for All Languages
Currently most of the cross-lingual research involved only
top commonly used languages in the world for example
English, Mandarin, Spanish and Hindi. Also, research has
being done on languages that has being influenced most by
the economic and commercial of a country [14]. That means
in overall only a few languages have been through the
development of test corpus and an extensive formal
evaluation. It is unfair to only consider the cross-lingual IR
research focussing only on these languages. There are a lot
of other languages that are equally important to the people
which they use to search for information. There is a need for
research that focus on these languages and currently many
research have been done based on the native languages of the
researchers such as the Indonesian [20] and Urdu [21]. It
shows that cross-lingual IR is possible to be available for
every language.
