Main event

TALK 1: Multimedia Retrieval in Lifelogging by Liting Zhou

(15 mins) The Multimedia Retrieval in Lifelogging is aimed to cope with many types of media including images, videos, audios and biometric data. In this talk, we will give a quick introduction of lifelog and talk about the lifelog moment retrieval in NTCIR workshop. Furthermore, the development of Lifelog Retreival system also will be described detailedly.

TALK 2: Sentiment Analysis Enhanced by User and Product Context by Chenyang Lyu

(15 mins)Past work that improves sentiment analysis by encoding user and product information has been limited to considering only the text of the current review. We investigate incorporating additional review text available at the time of sentiment prediction that may prove meaningful for guiding prediction. Firstly, we incorporate all available historical review text belonging to the author of the review in question. Secondly, we investigate the inclusion of historical reviews associated with the current product (written by other users). We achieve this by explicitly storing representations of reviews written by the same user and about the same product and force the model to memorize all reviews for one particular user and product. Experiment results on IMDB, Yelp 2013 and Yelp 2014 datasets show improvement to state-of-the-art of more than 2 percentage points in the best case.
