An information processing apparatus includes: a first storage to store correspondence data that includes a plurality of mental and physical states and keywords related to each of the states; a second storage to store messages representing contents tweeted for an observed target by a plurality of observers; and a data processor to detect keywords related to each of the states from the messages based on the correspondence data and create presentation information which includes information data arranged correspondingly to each of the states wherein the information data is arranged for each of the messages including the keywords related to the corresponding state and includes the keyword detected from the each of the messages.

Information processing apparatus and information processing method

A problem to be solved is to assist input of information by a user. An information processing device of one embodiment includes a keyword sequence generator generating a keyword sequence by performing morphological analysis on text data in natural language; a category information sequence generator acquiring category information corresponding to each keyword of the keyword sequence based on a database in which keywords are associated with category information and generating a category information sequence; the pattern extractor selecting a category information sequence pattern from category information sequence patterns according to correlation between the category information sequence and each category information sequence pattern; and a determiner comparing the selected category information sequence pattern with the category information sequence and generating presentation information according to a difference between the selected category information sequence pattern and the category information sequence.

In the method of the present invention, one of each pair of photons connected through entanglement is distributed to a transmitting station, relay stations and a receiving station. After the photons reach secure sites, such as the relay stations, a base for detecting photons is determined between adjacent sites, and then photons are detected in each site, which makes it possible to obtain a secret key used for secure information transmission between relay stations using bases coincide with each other every time. Also, in the present invention, a high-quality random number sequence serving as a secret key is automatically generated in a physical manner every time by detecting a superposition state of an entanglement and procedures corresponding to those in which a secret key itself is transmitted in a form of a quantum cryptogram are performed.
