【正确答案】正确答案：Concordance; The computer has the ability to search for a particular word, sequence of words, or perhaps even a part of speech in a text. The computer can also retrieve all examples of a particular word. It can also calculate the number of occurrences of a certain word so that information on the frequency of the word may be gathered. We may also be interested in sorting the data in some way—for example, alphabetically on words occurring in the immediate context of the word. This is usually referred to as concordance.
