Abstract
By using event extracting knowledge, a plurality of events are extracted from a text. One of the events is extracted as a targeting event, and also one or more of the events other than the targeting event are extracted as targeted events, so that one or more combinations of the targeting event and the one or more targeted events are generated. A distance between a first text and a second text from which one or more of the combinations have been generated is calculated, so that a certainty factor of each of the combinations is calculated. One of the combinations is selected based on the certainty factors, so that the selected combination is displayed.
Claims13
An information processing apparatus comprising:
- an obtaining unit that obtains a text from a text set including a plurality of texts each of which is constituted by a character string and that can be arranged in an order;
- a first storage unit that stores an event extracting knowledge used for extracting from the text a plurality of events by which contents of the text are characterized;
- an extracting unit that extracts a plurality of events from the obtained text by using the event extracting knowledge;
- a generating unit that extracts a targeting event from the plurality of events and one or more targeted events from the plurality of events other than the targeting event, and generates one or more combinations of the targeting event and the targeted events;
- a calculating unit that calculates a distance indicating a difference in closeness in terms of the order between a first text from which the combination has been generated and a second text from which the combination has been generated, and calculates, for each of the combinations, a certainty factor indicating a degree of certainty of the combination of the targeting event and the targeted event in such a manner that the shorter the distance is, the higher a value of the certainty factor is;
- a selecting unit that selects, as a combination for the text set, one of a first combination and a second combination, the first combination having the certainty factor calculated by the calculating unit that is equal to or larger than a threshold value, and the second combination having the certainty factor placed in an ordinal rank equal to or lower than a predetermined ordinal rank;
- and
- a display controlling unit that causes a displaying unit to display the selected combination.

An information processing method comprising:
- obtaining, by an obtaining unit of an information processing apparatus, a text from a text set including a plurality of texts each of which is constituted by a character string and that can be arranged in an order;
- extracting, by an extracting unit of the information processing apparatus, from the obtained text a plurality of events by using the event extracting knowledge used for extracting from the text the event that is stored in a first storage unit and characterizes contents of the text;
- extracting, by a generating unit of the information processing apparatus, a targeting event from the plurality of events and one or more targeted events from the plurality of events other than the targeting event, and generating one or more combinations of the targeting event and the targeted events;
- calculating, by a calculating unit of the information processing apparatus, a distance indicating a difference in closeness in terms of the order between a first text from which the combination has been generated and a second text from which the combination has been generated, and calculating, for each of the combinations, a certainty factor indicating a degree of certainty of the combination of the targeting event and the targeted event in such a manner that the shorter the distance is, the higher a value of the certainty factor is;
- selecting, by a selecting unit of the information processing apparatus, as a combination for the text set, one of a first combination and a second combination, the first combination having the certainty factor calculated by the calculating unit that is equal to or larger than a threshold value, and the second combination having the certainty factor placed in an ordinal rank equal to or lower than a predetermined ordinal rank;
- and
- causing, by a display controlling unit of the information processing apparatus, a displaying unit to display the selected combination.
