问题     Natural language interfaces enable the user to communicate
with the computer in French, English, German, or a human【S1】______
language. Some applications of such interfaces are database
queries, information retrieval from texts, so-called expert systems,
and robot control. Current advances in recognition of spoken【S2】______
language improve the usability of many types of natural language
systems. Communication with computers using spoken language will
have a lasted impact upon the work environment, completely new【S3】______
areas of application for information technology will open up.
However, spoken language needs to be combined to other modes of【S4】______
communication such as pointing with mouse or finger. Because such【S5】______
multimodal communication is finally embedded in an effective
general model of cooperation, we have succeeded in turning the
machine to a partner. Much older than communication problems【S6】______
between human beings and machines are these between people with【S7】______
different mother tongues. One of the original aims of computational
linguistics has always been fully automatic translation between
human languages. From bitter experience scientists have realized
that they are still far away from getting the ambitious goal of【S8】______
translating unrestricted texts. Nevertheless, they have been able to
create software systems that simplify the work of human translators
and clearly improve their productivity. Less than perfect automatic
translations can also be of a great help to information seekers who【S9】______
have to search for large amounts of texts in foreign languages.【S10】______
【S9】
