Personalization with DNA profiles

DNAklik has developed a method to generate DNA profiles for data objects and visitors to the website. This method is especially suitable for websites with a large collection of items. By matching DNA profiles, suggestions can be made to find similar items or users with common interests.

Principle of the method

DNA profiles are built up through the selection of content from the website visitors. By means of the exchange of the DNA building blocks between the DNA profile of the user and the DNA profile of the content, DNA profiles are created for users and content items. Similar content gets DNA profiles that are similar to each other, as well as visitors with similar interests. These profiles can be used for:

  • Finding similar items
  • Connecting web visitors with similar interests
  • Giving suggestions of interesting items to website visitors
  • Organize a collection

Because the DNA profiles are constantly changing, so do the suggestions. This is ideal for discovering new interesting information. Unlike an exact search command or the use of an index or tag system, relationships can arise between similar content. This is reflected in the prototype (see DNA profiles) where matching also arises between, for example, red with orange and rose. This is in contrast to a tag or index system, where there is never a match between red and another color.

Organize collections

To make digital collections searchable, they must be provided with metadata. Especially if the digital collection does not consist of texts but of photos, films or sounds, it cannot be organized if no metadata is linked to the data files. Even if the meta data is incomplete or inconsistent, this collection can be difficult to search. With the method described here it is possible to unlock these collections.

Prototype with colors

Dna profiles show a prototype of this system. The content consists of 4096 colors. This collection represents a collection without meta data. By instructing users to select the color that best matches a pre-chosen color in a screen with 30 colors, DNA profiles are built up for the user and the color. The screen is filled with 24 colors that best match the DNA profile of the user and the chosen color.

You can participate in the test by taking a color in mind and looking for the color by always choosing the color that best matches it. If you want to switch to a different color, you can remove Your DNA and start over again. By clicking on "items" you will see colors that best match your personal DNA stored in a cookie. You can also create an account or different accounts, then your profile will be saved and you can continue later and follow the system properly.

Improved customer experience

The principle of this method is fundamentally different from personalization techniques where extensive data (via tracking, mining and data analyses) is collected from users. The advantage of this is:

  • No need to determine which data is relevant for giving suggestions
  • No breach of GDPR legislation. The only thing that is stored is a DNA profile that is otherwise unusable outside the system.
  • The system is relatively simple and therefore easy to implement

The system is ideal for navigating through a website with a large collection of items, e.g. a webshop or a museum collection. It is not primarily intended as a marketing strategy to achieve certain targets but purely to help the customer to find interesting content.

I have made a demo in which this method is used to navigate through the collections of the expert sites of the Gemeente museum. There, the collections of Delft pottery, Asian ceramics and Mondrian have been combined. If you are curious how this works, please contact me.
