Goal and impact

The aim of the algorithm is to enable residents, councillors and municipal staff to easily find council meetings and information. This promotes greater transparency and facilitates democratic processes. The council information system contains information about council meetings and council decisions. The Video Search & AI module functions as a search engine. It allows you to easily find the information you are looking for. The search engine is accessible to councillors, residents and council staff. Users ask questions of the search engine and receive relevant information in response.

Considerations

The search engine’s algorithm helps people find information more quickly in the council information system. It can provide a summary of the key information you are looking for. One drawback of semantic search is that the algorithm understands why you are searching for something and, as a result, learns more about you.

Human intervention

Users always see the original video or documents. The system only provides search results and summaries. There is no automated decision-making.

Risk management

If you use a search engine, there is a chance that you will be given incorrect information or answers. That is why you will see a warning on the web page. The search engine cannot change the original information in the council’s information system. The local authority reports any errors in the search engine to the supplier.

Legal basis

Article 23 of the Local Government Act states that council meetings are open to the public. The search engine helps people to find these meetings.

Data

Videos of public meetings, subtitles, metadata (date, speaker and topic).

Technical design

The search engine searches the council information system based on the query entered by the user. When a user enters a query into the search engine, the search engine searches the meeting transcripts. When searching for information, the search engine utilises speech recognition, semantic search and artificial intelligence. Semantic search is a search technology that does not search strictly by keywords, but also considers the meaning and intent of the search query. These technologies make the spoken text from meetings and the metadata of documents in the council information system searchable.

The artificial intelligence answers the user’s query and presents the information found in an understandable way. It also summarises the information found and links to the original source via a Large Language Model.
