In the post Knowledge Base 2: The structure and the method of building [LW · GW] I proposed to build a knowledge base on various topics. In this post I am going to present some possible applications of this knowledge base constrained to knowledge about products available on the market. Possible applications of the general knowledge base are described in the post Knowledge Base 4: General applications [LW · GW].

Shopping advisor

Imagine an application that uses a knowledge base of products sold in stores to help consumers choose the right products (see the picture).

The knowledge base is marked in green. In this application we are only interested in a part of the knowledge base about products available on the market – initially only groceries. Information about products will be added to the database by producers, stores, and consumers.

A consumer sets (in the application’s profile) criteria of products that are important to him, specifying their weights. He can choose from 4 groups of criteria:

Then the consumer can go to a store and use his smartphone to scan bar codes of selected groceries. A list of scanned products will appear on his smartphone. Products that meet the selected criteria will be marked in green, products that meet the criteria but are much cheaper in another store will be marked in yellow, and products that do not meet the criteria will be marked in red. Additionally, if a product does not meet the criteria, the application may suggest a similar but better product.

The rules translating information set in a customer profile into assessment of a product can be written by experts as plug-ins for the application.

Shopping report

We can also imagine another function. Stores collect information about products you buy using loyalty cards. Thanks to the General Data Protection Regulation you can ask stores to share this data with you via the Internet. Having this data, you can order for example monthly reports containing assessment of products you bought, listing the worst products often bought by you, and proposing better alternatives.

Similar databases and applications

There are already databases containing partial information about groceries, for example about their composition (amount of sugars, fat, proteins and additives such as preservatives and food colorings). However, most often they are not free – free databases are available for products sold in the United States, France, and Switzerland – that is why using them in new computer applications can be troublesome.

In some countries there are applications that evaluate groceries taking into account only one criterion, for example food additives or manufacturer country. Unfortunately, there is no application that takes into account all criteria that are relevant to a consumer [1].

To sum up, we lack a holistic solution to the problem of choosing products. I think that this is due to a lack of a generally available knowledge base – that is why I proposed a method of its building in the post Knowledge Base 2: The structure and the method of building [LW · GW].

List of similar databases, applications, and concepts

Other possible uses of the knowledge base about products

I could add to the system a list of products owned by me, for example: Peugeot 307 car, Bosch GSB 1300 drill, Toshiba 55V5863DG TV set etc. Thanks to this a manufacturer can easily inform me if, for example, he wants to call car owners to a workshop due to a manufacturing defect. Finding a spare part will also be easier because the knowledge base will contain information about spare parts compatible with a product I own.

Additionally, if I want to sell a used product, it is enough to select it from the list of my products, check an I want to sell option and optionally provide differences between my product and the new product resulting for example from its usage. Information about the available used product will appear automatically next to new products after clicking the Buy button on the product overview page (see figure 4 in the post Knowledge Base 2: The structure and the method of building [LW · GW]).

Moreover, instead of choosing the I want to sell option, I could choose an I want to lend option. If someone needs a drill for a while, then maybe borrowing it from somebody living in the same estate will be more convenient. If there are no people willing to lend a drill at the moment, then the person willing to borrow it can subscribe to the drill term on the estate and he will be notified when the owner of a drill selects the I want to lend option. On the other hand, the drill owners living in the estate can be notified that someone has subscribed to this term.
