By using Japanese Keyword Extraction API, you can create an application which extracts "keywords" from an input document.
Japanese Keyword Extraction API extracts "keywords", such as person names, location names, organization names, and so on, from an input document consisting of a title and a body. The "keywords" are scored by the position of appearance in the title and the body, the number of occurrences in the document, and the type of named entity.
The "keywords" are useful to tag news articles to make it easier to search.
