SYSTEMS & DATA SETS

Ÿ NTU Online Judge System:

URL: http://acm.csie.org

Description: It’s a website for hosting competitive programming contests and training NTU students to participate ACM ICPC contests. The system has collected 3023 problems, 502 contests, and 716 students registered. It helps NTU to win 3 gold medals in ACM ICPC World Finals (2010, 2013, 2014).

Ÿ Benchmark for Chinese News Stance Retrieval Task:

URL: https://aidea-web.tw/topic/b6abbf14-2d60-456c-8cbe-34fdfcd58967

Description: It’s ad-hoc retrieval task for searching Chinese news documents, where queries must cover a stance on a controversial topic such as “support same-sex marriage.” The task contains more than 800,000 news articles and 70 queries. The dataset and its annotations (ground truth) will be released after the competition.

Ÿ NTU Online Judge System: The website hosting competitive programming contests is to train NTU students to participate ICPC programming contests. There are 3023 problems, 502 contests, and 716 students registered in the system.

Ÿ Example Contest in NTU Online Judge System:

Ÿ ACM ICPC World Finals 2014, 4^th place (Gold Metal Award):

Ÿ ICPC World Finals 2019, 5^th place (Silver Metal Award):

ICPC is considered as the "Olympics of Programming Competition." From among 13,422 teams chosen from 2,736 universities in 102 countries, we were in 5^th place (silver medal) at ICPC World Finals 2019. We were

also the first team (and the only one team) solving problem J, one of the most difficult problems at World Finals 2017. It’s worth mentioning that from among 10,681 teams chosen from 2,286 universities in 94 countries, we were in 4th place (gold medal) at World Finals 2014. This is the third time NTU teams I led were warded the highest honor, the gold medal (top 4 teams). Under my supervision, NTU teams have won 3 gold medals and 1 silver medal since 2010. The outstanding achievement has broken the best record ever set in Taiwan.

Ÿ AI Cup − Chinese News Stance Retrieval Task (2019/03~2019/11): It’s the first ad-hoc retrieval task for searching Chinese news documents with controversial topics.
