Summary

This project will allow users of the Open Food Facts website, mobile app and our 100+ mobile apps ecosystem, to get highly personalized search results without sacrificing their privacy.

The project is funded by the NGI0 Discovery Fund managed by NlNet.


Overview

High level view of the project components and data flow:

Diagram source: https://vecta.io/app/edit/-M2XyVv8ZoaLNrW-zQoT

Software Bill of Materials

The project uses these software components:

  • Server side / backend
  • Mobile app
    • Flutter + Dart (cross-platform for Android and iOS)

Collaboration

  • Project planning, status and documentation: this wiki
  • Code, bug tracking etc. : GitHub
  • Discussion : #personal-search channel on the Open Food Facts Slack

Tasks and timeline

The project starts in Q1 2020 and is projected to last until Q2 or Q3 2020. It contains 4 sub-tasks that can be worked on in parallel.

1. Ingredients analysis and search features extraction - completed from March to May 2020

We need to transform the text of ingredients list in local languages to structured data that we can use to determine if a food product is vegetarian, vegan, contains palm oil, etc.

Milestones

  • Assessment of the current Ingredients Analysis Quality for major EU languages
  • Improvements to the ingredients taxonomy and the analysis code
    • Dutch
    • English
    • French
    • German
    • Italian
    • Spanish
  • Report with metrics of the achieved improvements for each language

2. Server-side product indexing and search - completed from May to October 2020

For each product, we will precompute a list of similar products (e.g. from the same categories, with similar characteristics or possible uses, and available in the same country), and create a search API to return generic search results from the server to the mobile app. The mobile app will then be able to personalize the generic search results according to the preferences of the user.

Milestones

  • Functional specs
  • Technical specs
  • Server-side implementation

3. Client-side libraries for personalized product filtering and ranking - Started in September 2020

On device in the mobile app, the generic search results from the server will be filtered and ranked according to the preferences of the user, which will stay on her local machine or phone. We will create an open-source library so that the personalization of results can be implemented in the Open Food Facts app, but also 3rd party apps.

Milestones

  • Libraries implementation and documentation
    • Implement the personalization of results in Javascript - done (deployed on OFF web site)
    • Package and document the Javascript filtering and ranking code in a library
    • Implement the personalization of results in Javascript - done (currently embedded in the new OFF flutter app)
    • Package and document the Flutter filtering and ranking code in a library

4. User interface on the Open Food Facts web site and mobile app - Started in September 2020

Users will be able to store on their device their personal preferences. When searching food products, or when scanning a food product, they will see results personalized results, with indications on how well they match their personal preferences.

Milestones

  • Deployment of feature in OFF web site - deployed on January 6th 2021
  • Deployment of feature in mobile app - in progress (new OFF Flutter app)
  • Accessibility review
    • OFF web site - done
    • Flutter app (first version)
      • Determine what are the few missing must haves
      • Implement the must haves
      • Minimal branding / design / doc / play stores pages
      • Launch

Implementation

Personal Search V2

Branding and communication

We will first make a “soft” launch of Personal Search on the OFF website and in the new mobile app, without a big announcement to external users, so that we can gather feedback and work on the next version of Personal Search. But Personal Search is very transformative for Open Food Facts, as it focuses much more on the value that OFF can bring to the general public, and it is a great opportunity to communicate about that added value and recruit a much larger active audience, beyond our existing community of contributors.

Milestones

  • Determine the branding: a new name, a new universe?
    • Ideation, experiments / proposals, decision
  • Create the matching design and illustrations
  • Imagine and implement a few viral features
    • Ideation, identification of possible quick wins
    • e.g. sharing personal top X lists
  • Imagine Personal Search V2 features, draft plan
    • e.g. integration with Folksonomy Engine, tracking, inventory, seamless experience on web and mobile etc.
  • Plan the communication campaign and prepare the assets
  • Launch of Personal Search V2
