Due to the COVID-19, this course will be delivered over Zoom. All lectures will be recorded.
This course mainly focuses on introducing current methods and models that are useful in analyzing and mining real-world text data. It will put emphasis on unsupervised, weakly supervised, and distantly supervised methods for text mining problems, including information retrieval, open-domain information extraction, text summarization (both extractive and generative), and knowledge graph construction. Bootstrapping, comparative analysis, learning from seed words and existing knowledge bases will be the key methodologies.
There is no textbook required, but there are recommended readings for each lecture (at the end of the slides).
Knowledge about Machine Learning and Data Mining; Comfortable coding using Python, C/C++, or Java; Math and Stat skills.

Data Mining Challenge (30%)
It is a individual-based text mining competition with quantitative evaluation. The challenge runs from Oct 20 2020 0:00:01 AM to Nov 24, 2020 4:59:59 PM PT. Note that the time displayed on Kaggle is in UTC, not PT.
- Challenge Statement, Dataset, and Details: TBD
- Kaggle challenge link: TBD
- Team-Based Open-Ended Project
- 1 to 4 members per team. More members, higher expectation.
- 3 to 4 members are recommended, given the limited presentation slots.
- Project Proposal (5%)
- Define your own research problem and justify its importance
- Be ambitious! We could aim for ACL 2021 conference!
- Research Paper (20%)
- Report due on Dec 13, End of the day, Pacific Time.
- Write a 5 to 9 pages report (research-paper like following ACL template). The pages here do not include references.
- Come up with your hypothesis and find some datasets for verification
- Design your own models or try a large variety of existing models
- Submit your codes and datasets; Github repos are welcome
- Up to 5% bonus for working demos/apps towards the total course grades
- Presentation (20%)
- The orders will be decided randomly after the teams are formed.
- The slides must be ready 2 days before the presentation date. So other students can have the access and think about questions.
- The presentation follows a typical conference style: 20 mins for each team including Q&A
- Question Asking and Handling (5%)
- Asking questions is an important part of research. You are strongly encouraged to ask questions to other teams. It will be a part of your presentation grade.
- Handling questions is also an important skill for researchers.
