Example (Step by step)

First you need to have a document sample that you want to use with smartClassify. It can be any document type such as: invoice, receipt, letter, email etc. For e.g you can use the invoice letter below:

Inorder to use our smartClassify tool you need to have an API key which can be generated from here.

If you don’t have an account, first you need to set up your account then you can generate the API key. Create an account here.

After you have generated your API key, then you can use smartClassify in any popular programming language, where you can find the code snippets here.
Run your code. You will receive a JSON response with the invoice details.

(b) how the AI system interacts or can be used to interact with hardware or software that is not part of the AI system itself, where applicable;

The AI system is integrated on the webpage https://laigo.ai/ and can be called by using API. It is served on Laigo internal servers.

[…]

(d) the description of all forms in which the AI system is placed on the market or put into service;

The AI system is integrated on the webpage https://laigo.ai/ and can be called by using API. It is served on Laigo internal servers.

(e) the description of hardware on which the AI system is intended to run;

The AI system smartClassify is running on Laigo internal server, located in Germany.

(f) where the AI system is a component of products, photographs or illustrations showing external features, marking and internal layout of those products;

The AI system smartClassify is deployed on Laigos internal server, located in Germany. It is part of a Software as a Service product.

(g) instructions of use for the user and, where applicable installation instructions;

All instructions of the product usage are mentioned on Laigos homepage https://laigo.ai/docs.

2. A detailed description of the elements of the AI system and of the process for its development, including:

(a) the methods and steps performed for the development of the AI system, including, where relevant, recourse to pre-trained systems or tools provided by third parties and how these have been used, integrated or modified by the provider;

The AI system smartClassify is based on the Open Source Model LayoutLM from Microsoft. A fine tuning took place at Laigo GmbH with internal German dataset.

(b) the design specifications of the system,

No modifications has been done to the original neural network architecture. Only the output classes are changed.

namely the general logic of the AI system and of the algorithms;

Classify German document types between advertisement, delivery note, email, form, handwritten, and invoice. Algorithm and approach can be found here: https://arxiv.org/abs/1912.13318, 20.12.2022.

[…]

3. Detailed information about the monitoring, functioning and control of the AI system, in particular with regard to:

its capabilities and limitations in performance, including the degrees of accuracy for specific persons or groups of persons on which the system is intended to be used and the overall expected level of accuracy in relation to its intended purpose;

Especially, if the quality of the image and the resolution is bad, text can be missed or misinterpreted in a wrong language. This appears also, if the orientation of the picture/PDF is not aligned to the orientation of the text. With this, it is possible that documents are classified not properly.

The overall accuracy is independent of specific persons or groups of persons which the system is intended to be used.

the foreseeable unintended outcomes and sources of risks to health and safety, fundamental rights and discrimination in view of the intended purpose of the AI system;

No risk to health and safety expected. Fundamental rights are respected and no discrimination of certain individuals considered.

[…]

5. A description of any change made to the system through its lifecycle;

As the AI system has been released with the first version, no changes appeared so far.
