1-It is assumed that the user provides you with a list of words, one per line, in a text file called "words.txt". The text file named "words.txt" is located in the directory: D:\Java \TP4\words.txt.Your application must find the answers to the following questions when it is run on the command line like this: "java MonLucene mots.txt" where the file "mots.txt" is in the current directory. -The first concept to find is the one grouping the most documents and having at least one word in the list provided by your user. If there is more than one, find them all. (Give only the words defining the concept. Do not include the list of documents.) -The second concept to find is the one using two words in the list, and the largest number of documents. Again, if there is more than one, you have to find them all. These concepts result in pairs of words that are related because they frequently appear together in the same document. (Give only the sets of words defining a concept. Do not include the list of documents.) -Finally, the last concept to find is the one using three words appearing in the largest number of documents. If there is more than one, find them all. These concepts result in triplets of words that are related because they frequently appear together in the same document. (Give only the sets of words defining a concept. Do not include the list of documents.) Index. For the first problem, do a search with each of the words. Then find the most popular word (or most popular words), i.e. the word appearing in the most documents. Then repeat with the word pairs and, finally, with the word triplets. You must submit not only the code, but the solution and result corresponding to the following list of words : man woman house home school dog cat land country white 1 children example paper music letter river book town room friend Tips. If the word "man" is present in 500 documents, then the words "man" and "woman" must be present in at most 500 documents. Make sure your stats make sense! -We asked you to use truncation. What would happen if you repeated the experiment without performing word truncation. Explain your point of view. O ( n ) , O ( n 2 ) O ( n 3 ) 2.
