Abstract
At least one processor of a sentence extraction system specifies at least one candidate sentence based on a predetermined extraction condition, the candidate sentence being a candidate for a sentence to be extracted from among a plurality of sentences; specifies at least one linked sentence that has a link to the at least one candidate sentence; and determines whether to extract the at least one linked sentence, based on whether to extract the at least one candidate sentence.
Claims13
A sentence extraction system comprising at least one processor configured to:
- obtain a score based on an extraction condition for a plurality of candidate sentences,
- sequentially select a predetermined number of candidate sentences, beginning with a candidate sentence with a higher score,
- select at least one linked sentence for every candidate sentence selected,
- wherein the at least one linked sentence has a score that fulfills a predetermined selection criterion,
- wherein the at least one linked sentence does not fulfill the extraction condition, and
- wherein the at least one linked sentence has a link to the candidate sentence, and
- determine whether to extract the at least one linked sentence, based on whether to extract the at least one candidate sentence.
A method for extracting a sentence, comprising:
- obtaining a score based on an extraction condition for a plurality of candidate sentences,
- sequentially selecting a predetermined number of candidate sentences, beginning with a candidate sentence with a higher score,
- selecting at least one linked sentence for every candidate sentence selected,
- wherein the at least one linked sentence has a score that fulfills a predetermined selection criterion,
- wherein the at least one linked sentence does not fulfill the extraction condition, and
- wherein the at least one linked sentence has a link to the candidate sentence, and
- determining whether to extract the at least one linked sentence, based on whether to extract the at least one candidate sentence.
A non-transitory information storage medium storing a program for causing a computer to:
- obtain a score based on the extraction condition for a plurality of candidate sentences,
- sequentially select a predetermined number of candidate sentences, beginning with a candidate sentence with a higher score,
- select at least one linked sentence for every candidate sentence selected,
- wherein the at least one linked sentence has a score that fulfills a predetermined selection criterion,
- wherein the at least one linked sentence does not fulfill the extraction condition, and
- wherein the at least one linked sentence has a link to the candidate sentence, and
- determine whether to extract the at least one linked sentence, based on whether to extract the at least one candidate sentence.
