Reading and answers the question:
Simply stated, computational linguistics is no more than the use of1. According to the passage, computational linguistics involves
electronic digital computers in linguistic research. These machines
are employed to scan texts and to produce, more rapidly and more
reliably than is possible without their aid, such valuable tools
5 for linguistic and stylistic research as word lists, frequency counts,
and concordances. But more interesting and theoretically much more
difficult than the compilation of lists, is the use of computers
for automatic grammatical analysis and translation. A considerable
amount of progress was made in the area of machine translation in
10 the United States, Great Britain, the Soviet Union, and France between
the mid-1950's, and the mid- 1960's but much of the original impetus
for this work has now disappeared, due in part to the realization
that the problems involved are infinitely more complex than was at
first envisaged. Thus, translation continues to remain as much an
15 art as a science if not more so.
