| description | PROBLEM TO BE SOLVED: To perform extraction of an important keyword in accordance with an intention of a video producer from a scenario, and the extraction of the important keyword without preparing a keyword dictionary, even when an error is present in a result of telop recognition. SOLUTION: A scenario text and a telop document are read on the basis of designated video identification information, the telop document is analyzed to calculate a telop importance level, a noun phrase is extracted from the telop document on the basis of the telop importance level, a character string of the noun phrase extracted from a telop and a character string of the scenario of the scenario text are compared, the according noun phrase is extracted to produce a lookup table, a topic break point is extracted on the basis of the lookup table, and the keyword is extracted.
