<p>A search server is provided with a category database and a dictionary registration unit. Said category database stores category-information entries each consisting of the following associated with each other: location information indicating a geographical location; words applied to said location; and a user ID identifying the user who applied said words to said location. The dictionary registration unit reads out first input information, indicating locations to which a first user applied first words, and second input information, indicating locations to which a second user applied second words. If the dictionary registration unit determines, on the basis of said information, that there are at least a prescribed number of locations to which both the first user and the second user applied said words, dictionary data in which the aforementioned first words and the aforementioned second words are associated with each other is generated and registered in a dictionary database.</p> |
