Example (Step by Step)

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

1. Inorder to use our smartICR 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.

1. After you have generated your API key, then you can use smartICR in any popular programming language, where you can find the code snippets here.

2. Run your code. You will receive a JSON response with the invoice details.

SmartICR is developed for text recognition and detection of document images. It is extracting text from documents and is converting scanned PDF or images into searchable PDF-A. With this, text images can be detected, marked and copied.

the person/s developing the system the date and the version of the system:

The AI system smartICR was developed at

Laigo GmbH Eckenerstr. 65 88046 Friedrichshafen

and

Laigo DOO Cevahir Sky City, 16B

Municipality Aerodrom, 1000 Skopje North Macedonia

Releasing Version 1.0 of the AI system, on the 20.12.2022.

(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 smartICR 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 smartICR is deployed on Laigos internal server, located in Germany. It is part of a Software as a Service product and therefore a IT service.

(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 smartICR is based on the Open Source OCR Engine from Google Tesseract. Laigo GmbH is using Python Wrapper of Tesseract and is providing the model over an API on https://laigo.ai/. Pre- and post processing steps required for the OCR usage is developed by Laigo.

(b) the design specifications of the system, namely the general logic of the AI system and of the algorithms;

The AI system has same existing original design of Tesseract OCR of Google. For text detection a LSTMN approach has been used and applied. Detailed information can be found in technical papers of Google.

the key design choices including the rationale and assumptions made, also with regard to persons or groups of persons on which the system is intended to be used;

No design choices or modifications are done from the existing system by Laigo GmbH.

the main classification choices;

Laigo GmbH classifies this AI system with “no risk”, since none of the EU requirements are applicable for this use case.

what the system is designed to optimise for and the relevance of the different parameters;

The AI system is designed to optimize OCR by considering context. With this a higher accuracy can be reached compared to classical OCR approaches.

[…]

(c) the description of the system architecture explaining how software components build on or feed into each other and integrate into the overall processing;

Laigo is using the python wrapper of the open source Tesseract OCR engine and integrating it into Laigo own API system using microservices.

the computational resources used to develop, train, test and validate the AI system;

Laigo is using the pre-trained OCR engine from Google. No additional training, validation and testing is done. Further information can be found on Googles technical papers.

(d) where relevant, the data requirements in terms of datasheets describing the training methodologies and techniques and the training data sets used, including information about the provenance of those data sets, their scope and main characteristics;

Laigo GmbH did not fine-tune the existing Tesseract OCR engine and therefore no additional datasets or training methodologies have been used, beside the once which have been mentioned by Google.

[…]

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. Certain preprocessing methods which are applied, are improving the accuracy of text recognition.

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.

[…]
