PROBLEM TO BE SOLVED: To extract words in the field same to that of a small number of words input by a user, and to display the extracted words to collect the similar words in a two-dimensional diagram. SOLUTION: This display system is provided with input positive examples that are the plurality of small number of input words, a database D storing a fixed volume of document data, a pattern extraction part 1 for performing full text retrieval of the input positive examples that have been input in the database D, and for extracting a pattern appeared in the periphery of the plurality of input positive examples, and a word extraction part 2 for performing full text retrieval of the pattern extracted by the pattern extraction part 1 in the database D, and for extracting an expression extracted by the pattern, and a word display part 3 for inputting an aggregate paired with the word and a context into a visualization means 4 to determine coordinates of the each word in two-dimensional map, and for outputting the diagram displayed with the words in the found coordinates, using the pattern used for the word extraction as the context, in the words of the extracted expression.
