| Outline of Final Research Achievements |
This work has two major results. One result relates to parsing micro-blog sentences. Since micro-blog articles often lacks sentence boundary markers, we first developed sentence boundary detector by using machine learning technique applied to word/character sequences. Then, we developed dependency analyzer including base phrase (so-called bunsetsu) chunker. Experimental results show our method outperforms existing software by 10 points. The other result is on trend analysis for micro-blog articles. We have developed a method for choosing an article which best describes a given burst word. The method applies sentence extraction to articles within the automatically identified burst period (for the given word).
