摘要： According to one embodiment, a content database stores one or a plurality of contents and meta data thereof. An input unit inputs at least one keyword. A generation unit generates virtual meta data of a virtual content. A virtual meta data includes one or a plurality of items. An extraction unit calculates a relevance ratio between the virtual meta data and the meta data of each content, and extracts at least one relevant content from the content database, of which meta data is relevant to the virtual meta data based on the relevance ratio. A decision unit decides a location to display the relevant content based on the relevance ratio. A display unit displays the relevant content at the location. The generation unit generates the virtual meta data by writing the keyword into at least one item of the virtual meta data.
