QALab PoliInfo2

In NTCIR15 QA Lab-PoliInfo2, we propose three tasks (Entity Linking task, Dialog Summarization task, Stance Classification task) to solve political issues by natural language processing.


Entity linking task

Entity linking task aims at identifying political terms included in politicians' statements, and is to resolve mention recognition, disambiguation and linking the mention with the knowledge base. In PoliInfo2, Entity linking is the task of assigning a unique identity of "legal name" which is one of the political terms. Given local assembly member's utterances, and systems extract a mention of “law name” and link the mention with the list of law names or Wikipedia.

Dialog summarization task

Dialog summarization task aims at summarizing the transcript of local assembly, taking the structure of dialogue into account. In PoliInfo2, systems participating in this task summarize the transcript based on the dialogue structure, which consists of “Members' questions” and “Governor's answer”. Given the transcript and summary conditions (speaker name and number of summary characters etc), they generate the structed document.

Stance classification task

Stance classification task aims at estimating politician's position from politician's utterances. In PoliInfo2, system participating in the task estimates the members of the same position from the utterances of the members of the Tokyo Metropolitan Assembly. Given the remarks of two members of the Tokyo Metropolitan Assembly, they have to be distinguished between the same party and different party.
