Write the required functions and script that prompts the user to enter the the names of any number of text files; reads these text files (creating one special semantic dictionary); optionally prints the dictionary in a special form; prompts the user to enter the name of a file containing a series of synonym problems (given a word, which of a series of words is its best synonym); then uses the semantic dictionary to try to solve each synonym problem, printing the results of each problem in a special form, and finally printing the percentage of problems that it solved correctly. The program will read the text file(s) to learn which words are similar to which others: each word in the semantic dictionary is associated with a context dictionary storing the words that appear in the same sentences (and how often they appear in the same sentences). The program will use a metric function to determine how similar any two words are by comparing their context dictionaries. By this process, the program can determine whether two words are more or less likely to be synonyms.
