In the information search apparatus, the character string information search unit includes a unit configured to, when the input character string contains a plurality of words, search an index DB, based on each word, that stores words and occurrence position information of the words to obtain a distance between occurrence positions of the words, and the similarity calculation unit includes a unit configured to calculate the degree of similarity based on the distance between occurrence positions of the words.

Information search method, apparatus, program and computer readable recording medium

The objective of the present invention is to enable a speaker to visually confirm whether or not his voice has reached a listener. In order to achieve this objective, in the present invention, the listener terminal generates a reception result for voice data, and the talker terminal displays the reception state based on this reception result. It is a further objective of the present invention to enable conversational timing to be achieved easily. In order to achieve this objective, in the present invention, the talker terminal sends utterance data prior to sending voice data, this utterance data being shorter than the voice data. The listener terminal displays the talker terminal's utterance based on this utterance data. Another objective of the present invention is to deliver voice data from the talker terminal to a particular listener terminal only, without having to form a private group. In order to achieve this objective, in the present invention, the server stores permission or denial for sending data from an optional terminal to another optional terminal, and distributes the voice data based on this storage.
