Cross-domain and Cross-modality Event Mining and Retrieval

Online news media and social media provide amounts of multimedia resources that are publicly available. The data records people’s daily lives, which are related to real-world events, e.g., protests, celebrations, natural disasters, festivals, politics, etc. This tutorial focuses on how to organizing the multi-domain and multi-modality data distributed on the Internet platforms according to their depicted real-world events. In this tutorial, event discovery and retrieval tasks crossing data domains and modalities will be introduced. The challenging issues will be discussed, and a few approaches from the perspectives of matrix factorization and deep learning will be presented, followed by the analyses on the experimental results. In particular, a few multi-domain and multi-modality real-world event datasets collected by the speakers will be introduced, which have been released on GitHub for peer researchers (https://github.com/zhengyang5).

He owns a YouTube channel teaching deep learning (in Mandarin) with more than 3.5M views and 44k subscribers.

Generative Adversarial Network and its Applications to Natural Language and Speech Processing

Generative adversarial network (GAN) is a new idea for training models, in which a generator and a discriminator compete against each other to improve the generation quality. Recently, GAN has shown amazing results in image generation, but the applications of GAN on text and speech processing are still limited. In this talk, I will demonstrate the applications of GAN on voice conversion, unsupervised speech recognition, unsupervised abstractive summarization, and sentence generation.

Before he joined SCUT, he was a post-doctor of City University of Hong Kong. He was a visiting scholar of Imperial College London, Tsinghua University, City University of Hong Kong, Nanyang Technological University. He published more than 100 papers (e.g., IEEE Transactions on Knowledge and Data Engineering, Neural Networks, Decision Support Systems, INFORMS Journal on Computing, Knowledge Based Systems, AAAI, EMNLP, AAMAS, CIKM, ER and ICTAI) and 2 books. He reviewed papers from conferences and journals related to information retrieval, semantic web, recommender system, data mining and database, including TKDE, TOIT, Decision Support Systems, WWWJ, KBS, JCST, CIKM and ER. He is a program committee member of conferences, including ICWL, ICWE, WAIM, ICEBE and NDBC. He is the co-chair of Social Networking and Mining Track in EIDWT-2013, DaSem 2013, SeCop 2015 and APWeb-WAIM 2018.

Leveraging Knowledge for Short Text Analysis

Since some documents are short and ambiguous, recent research enriches document representation with concepts of words extracted from an external knowledge base. However, this approach might incorporate task-irrelevant concepts or coarse granularity concepts that could not discriminate classes in a text classification task. This might bring noise to document representation and degrade text analysis performance. In this talk, we will introduce the latest developments of leveraging knowledge into short text analysis.

Sentiment and Emotion Detection over Text

The Web has generated product reviews, sentimental and emotional text about brand perception continuously, which can be utilized for capturing the opinions of consumers and the general public on product preferences, company strategies, and marketing campaigns. In this tutorial, the following topics will be discussed. The first topic is the detection of sentiments and emotions from short messages which is prevalent in social networks. The second topic is how to deal with noisy labels when conducting sentiment and emotion classification, because the ground truth for sentiments and emotions in social media is often constructed through surveys, hashtags or emoticons, where the labels may contain many errors. Last but not the least, sentiment and emotion detection over cross-domain corpora will be explored.
