| Outline of Final Research Achievements |
For the technologies for extracting and analyzing opinions, we developed a method for judging the importance of opinions, and presented a real-time tweet selection system for TV news programs. The system developed in this study collects tweets purporting to a TV news program, and chooses an appropriate tweet every 10 seconds. For the technologies for summarizing opinions, we formulated a summarization task as a combinatorial optimization problem, in which the nested tree was trimmed without losing important content in the source document. We used both dependency between words and dependency between sentences by constructing a nested tree. Next, we proposed methods for controlling the output sequence length for neural encoder-decoder models. Furthermore, we worked on Japanese sentence compression by a similar approach as in English.
