Zylab Disclosure Support

This algorithm helps employees review documents. They can search, group documents and find duplicates. This allows reviewers to quickly see whether parts of documents are important and whether the information may be public.

Responsible use

Goal and impact

The algorithm helps employees review documents quickly and properly. This is done when disclosing information. With smart search and filter functions, reviewers can better see which documents are important for a request. As a result, requests can be handled faster and better. Citizens and businesses get their questions answered faster.

Considerations

Manual review is intensive and error-prone. A suggestion list from the entity extraction algorithm captures all conceivable instances of individuals in the text.

Human intervention

The algorithm does not make its own decisions. Humans evaluate all results of searches, groups and finding duplicate documents. A human always gives the final result per document. If there is any doubt, a second reviewer or team leader looks at the document again.

Risk management

There is no risk of automated decision-making and the algorithm has no impact on fundamental rights because the algorithm does not make decisions with legal consequences. It only makes a proposal for anonymising personal data. The employee of the administrative body always makes the final check whether a document has been correctly anonymised.

Legal basis

The basis for the processes is as follows: 1. For disclosure: the Open Government Act (Woo). 2. For inspection: the General Data Protection Regulation (AVG). 3. For objection and appeal: the General Administrative Law Act (Awb). 4. For parliamentary enquiries: the Parliamentary Inquiry Act 2008 (WPE).

Operations

Data

The algorithm processes documents associated with the request. These can be e-mails, such as messages and attachments, as well as office documents such as Word, Excel, PowerPoint and PDF. In addition, chat messages and structured data from internal systems can be processed. These documents may contain personal data, such as names, e-mail addresses, phone numbers and job titles of employees, citizens and others. Metadata can also be used, such as creation date, author, file type and file name.

Technical design

Texts are recognised on the basis of Named Entity Recognition (NER) and a process within Insights extracts the names for further processing towards the management interface and automatic paint rules.

  • The algorithm underlines personal data in documents. An employee has to look at all pages and check if the document is properly lacquered. Then the software removes all highlighted information and blacklists it. After that, the documents can be published, for example under the Open Government Act (WOO).
