  16. Work distribution

  17. Data Source • RAPEX • Foodfacts&Amazon

  18. Parsing Rapex • Use python library to get the content of Rapex page • Use RE to extract each product from report • Use RE to extract all the columnsof the table for each product • Get a list of values of rows in the table • eg,[ [columnA1, columnB1, columnC1], [columnA2, columnB2, columnC2], …]

  19. Parsing Foodfacts&Amazon • Use Python RE to get a group of products in Food Facts, a list of product links is obtained. • Load each product link from the list and extract the UPC number. • Go to Amazon and search for the product there using the UPC number. • Save the Food Fact and Amazon product url.

  20. Parsing Foodfacts&Amazon 5. From Amazon : Product Description, Reviews Link and Star Ratings. 6. From Food Facts : Product Name, UPC, Ingredients, Warnings, Nutrition Facts, Description, Review Link And Stars, etc.

  21. Feeding Data To DB • Use Python DP-API connect to DB MySQLdb • Pass SQL commands and value of rows

  22. Table Examples

  23. Table Examples

  24. Integration • Integration over five iterations: • BuySafe v0.1 • Servlet • BuySafe v0.2 • Servlet + skeleton code (with errors) • BuySafe v0.3 • Struts 2 + skeleton code (on errors)

  25. Integration • BuySafe v0.4 • JSON + Struts 2 + database access • BuySafe v0.5 • JSON + Struts 2 + database acces + client GUI

  26. Integration problems • Communicating changes • Understanding changes • New technologies • Struts 2 • JSON

  27. Problems • Fragmented names of products and contents • Versions of programs • Python 2.7 – 3.3 • Database connection over distance • Lack of time – exams • Understanding team member implementation

  28. Other tools • ArgoUML • class generation

  29. Implemented functionality • Create/Edit profile • Search product • By barcode (no scanner) • By title • View product details • Review and rate the product • Flag the product

  30. Still to implement • Search product • By barcode with scanner • Product comparison • Product shopping list • Schedule DB updates (server) • Real-time parsing from other data sources (server)
