Yi-Shin Chen gives a presentation on natural language processing (NLP) and text mining. The presentation covers basic concepts in NLP including part-of-speech tagging, parsing, word segmentation, stemming, and vector space models. It also discusses word embedding techniques like word2vec, specifically the continuous bag-of-words and skip-gram models used to generate word vectors that capture semantic relationships. The goal is to obtain word representations that can better model linguistic knowledge compared to bag-of-words models.
Examples of working with streaming dataYi-Shin Chen
This document discusses examples of working with streaming data. It provides five examples:
1) Using news articles and stock data to predict stock market changes based on events.
2) An interactive music conducting system using motion sensors.
3) Analyzing social media streams to identify users' locations.
4) Identifying real-world events from social media streams.
5) Detecting mental health disorders by analyzing patterns in social media users' posts and interactions. The document outlines frameworks and methodologies for each example application of streaming data analysis.
This document summarizes Yi-Shin Chen's career journey from studying Information Management (IM) to pursuing Computer Science (CS). It describes her education in Taiwan obtaining degrees in IM and an MBA. She then earned a PhD in Computer Science from the University of Southern California. The document contrasts the IM and CS mindsets and how her background in both has influenced her research focusing on areas like data mining, text mining and emotion analysis. It also discusses her experiences as a faculty member in the Computer Science department at National Tsing Hua University.
The document provides an overview of text mining presented by Yi-Shin Chen. It discusses preprocessing text data which includes language detection, removing noise, stemming, POS tagging, and other techniques. It then covers basic concepts in natural language processing and parsing. Finally, it introduces basic data modeling concepts like the entity-relationship model and its use of entities, attributes, and relationships to represent data.
This document provides a quick tour of data mining. It begins with an overview of the evolution of data management techniques from manual record keeping to modern big data and data science. It then discusses what data mining is, focusing on algorithms for discovering patterns in existing data. Various examples of data mining applications are also presented, as well as the origins of data mining in fields such as machine learning and databases. Finally, an overview of the key steps in the knowledge discovery process is given, including data preprocessing, data mining, and pattern evaluation.
TAAI 2016 Keynote Talk: Intercultural Collaboration as a Multi‐Agent SystemYi-Shin Chen
The document discusses multi-agent systems and their real-world applications, including security games, kidney exchange matching algorithms, stock market simulations, and tsunami evacuation decision making. It then examines intercultural collaboration as a new research field, providing examples of online translation tools and an agricultural support project in Vietnam. Finally, it analyzes collaboration protocols and collaborative translation in multi-agent systems for intercultural projects.
TAAI 2016 Keynote Talk: It is all about AIYi-Shin Chen
This document discusses techniques for automatic concert video mashup and summarization. It begins with an overview of concert video mashup and the challenges involved in combining multiple concert videos into a seamless, high-quality outcome. It then describes the speaker's proposed methods for shot classification using deep learning models, audio sequence alignment, and generating a coherent video mashup using a conditional random field approach. The document concludes by demonstrating the methods on sample concert videos and discussing opportunities to improve the mashup quality by learning from professionally edited concert videos.
This document discusses the importance of research and how it applies to life. It begins by defining research as the close and careful study of a topic to discover new information. It then outlines the steps of the research process, including identifying problems, gathering information, developing methods, analyzing data, and presenting findings. The document suggests applying these research skills to everyday life issues like resolving conflicts between friends or determining how to help a sick child. Overall, it argues that research is a lifestyle that can help people better understand themselves and make informed decisions.
2016 datascience emotion analysis - english versionYi-Shin Chen
This document introduces Yi-Shin Chen and their work on emotion analysis using big data. It discusses using subconscious crowdsourcing to collect emotion data from social media without direct annotation. Key steps include preprocessing data, constructing graphs to identify emotion patterns, and ranking patterns for each emotion. Case studies analyze emotions in text and identify mental disorders in individuals by comparing patient and control groups. Potential applications include product feedback, election analysis, and more.

▷Women are more able to “go with the flow” than men
• Men want to push, pull, resist, direct the flow
• Women experience it—then mold with it to produce harmony

This is my son Leo.
On my quest to visual intelligence,
I think of Leo constantly and the future world he will live in. ...
This is my quest, to give computers visual intelligence and to create a
better future for Leo and for the World.

19. 女性特質 <Conversation with God, Book2>
▷When you have learned that
• might is not “right”;
→ that strength is not power over, but power with;
→ that absolute power demands of others absolutely nothing;
▷When you understand these things
• Then you may deserve to wear a woman’s body
• For you will at last have understood her Essence
