General goal: Scrape comments from user discussions at the sme.sk website. Store comments from several (hundreds) users from the last month in an SQLite3 database.
Task A
Create SQLite3 "database" with appropriate schema for storing comments from SME.sk discussions. You will probably need tables for users and comments. You don't need to store which comment replies to which one but store the date and time when the comment was made.
Submit two files:
- db.sqlite3 - the database
- schema.txt - a brief description of your schema and rationale behind it
Task B
Build a crawler, which crawls comments in sme.sk discussions. You have two options:
- For fewer points: Script which gets URL of a user (e.g. http://ekonomika.sme.sk/diskusie/user_profile.php?id_user=157432) and crawls his comments from the last month.
- For more points: Scripts which gets one starting URL (either user profile or some discussion, your choice) and automatically discovers users and crawls their comments.
This crawler should store the comments in SQLite3 database built in the previous task.
Submit the following:
- db.sqlite3 - the database
- every python script used for crawling
- README (how to start your crawler)
