In an acoustic signal separation device (), a determination unit () determines whether or not components from a plurality of sound sources are mixed in each of acoustic signals of respective components regenerated by a signal regeneration unit (), and when it is determined that a plurality of components is mixed, a series of processes by a feature value extraction unit (), a data estimation unit (), a data classification unit (), and a signal regeneration unit () is repeatedly executed until acoustic signals of the components of the respective sound sources are regenerated.

Acoustic signal separation device and acoustic signal separating method

An information processing device () includes: a morphological analysis unit () performing morphological analysis to divide each of an article body text included in an article and a caption of each of images into morphemes; a phrase acquiring unit () dividing the article body text into phrases on a basis of a result of the morphological analysis performed by the morphological analysis unit (); and a correspondence determining unit (). The correspondence determining unit () determines correspondence between each of the phrases of the article body text and the images by calculating a correlation between the caption and each of the phrases of the article body text on a basis of the result of the morphological analysis performed by the morphological analysis unit ().

Information processing device

Because an information providing system according to the present invention generates recognition object words for selecting one headline from a plurality of headlines in such a way that the recognition object words do not overlap one another, the information providing system can select a headline uniquely through the user's utterance, and present information (content) corresponding to the headline selected thereby, and therefore the convenience to the user is improved.
