Task Overview and Call for Task Participation

The 14th NTCIR (2017 - 2019)
Evaluation of Information Access Technologies
Conference: June, 2019, NII, Tokyo, Japan

Call for Participation to the NTCIR-14 Tasks:

Let's participate in a collaborative activity for enhancing Information Access technologies!

For the 20 years, NTCIR has been formulating the infrastructure for the evaluation, and contributing to development of the Information Access technologies. Consequently, NTCIR has been the major forum for researchers to intensively discuss the evaluation methodology of emerging information access technologies.
The 14th NTCIR, NTCIR-14, now calls for task participation of anyone interested in research on information access technologies and their evaluation, such as retrieval from a large amount of document collections, question answering and natural language processing. We welcome students, young researchers, professors who supervise students, researchers working for a company, and anyone who is interested in informatics.

Open Live Test for Question Retrieval ("OpenLiveQ-2")

"Question retrieval task in which participants can evaluate their systems in a production environment of Yahoo Japan Corporation’s community question-answering service."

Abstract:
Open Live Test for Question Retrieval (OpenLiveQ-2) task provides an open live test environment of Yahoo Japan Corporation’s community question-answering service for question retrieval systems. The task aims to provide an opportunity for a more realistic evaluation, to encourage participants to address question retrieval problems specific to a production environment (e.g. ambiguous/underspecified queries and diverse relevance criteria). The task is simply defined as follows: given a query and a set of questions with their answers, return a ranked list of questions.

Short Text Conversation("STC-3")

"Emotional Conversation Generation, Dialogue Quality, and Nugget Detection subtasks using Chinese and English dialogue data"

Abstract:
Following the success of NTCIR-13 STC-2 which attracted 27 research teams, the NTCIR-14 Short Text Conversation Task (STC-3) offers three new subtasks: Chinese Emotional Conversation Generation (CECG), Dialogue Quality (for Chinese and English), and Nugget Detection (for Chinese and English) subtasks. CECG: given a Chinese Weibo post and an emotion category (e.g., anger, disgust, happiness), return an appropriate response that matches the category. Dialogue Quality: given a helpdesk-customer dialogue, estimate the distribution of overall subjective scores (e.g. customer satisfaction, task accomplishment) as rated by multiple assessors. Nugget Detection: given a helpdesk-customer dialogue, estimate, for each utterance, the distribution of multiple assessors' labels over pre-defined classes (e.g. Not-A-Nugget, Regular Nugget, Trigger Nugget, Goal Nugget). A nugget is an utterance that helps the customer advance towards the Problem Solved state.

This is a collaboration across CLEF, NTCIR, and TREC. At NTCIR, participants will try to replicate/reproduce best practices from CLEF and/or TREC. At CLEF, participants will try to replicate/reproduce those from NTCIR and/or TREC, and so on. We want improvements that generalise and add up.
