**Name:** Yutong Wang **Team:** ML Team 3 (Predictors)

**Overview of Things Learned:**

**Technical Area:** I did research on data annotation tools available for both enterprise use and personal use, and wrote a report of one of them. For machine learning part, I have built a web crawler for [https://ai.stackexchange.com/](https://ai.stackexchange.com/) using scrapy library in order to get question titles, tags, individual question links and question content data.

**Tools Used:** Python, Pandas, JSON, Scrapy, Git, Colab, Visual Studio Code

**Soft Skills:** Communication with the team leader, tech leader and teammates about questions and confusion.

**Achievement Highlights**

1. Successfully scraping the StackExchange,ai website through Scrapy
2. Research and wrote a report of a data annotation tool called Scale

**List of Meetings attended**

- All team meetings except the first time
- Watch the other webinar recordings

**Goals for the Upcoming Week**

Build the training model for the data.

**Tasks Done**

1. **Task** : Successfully scraping the StackExchange,ai website through Scrapy **Hurdles** : Having issues using scrapy to crawl at first, and the StackExchange website banned users from accessing once one IP address performed a high number of requests.
2. **Task** : Research and wrote a report of a data annotation tool called Scale **Hurdles** : Very new to the idea of data annotation tool.
