Digital service agents
Sema is one example of an AI agent that helps you find relevant reports on SDU’s Analysis Portal. Sema does more than a standard keyword search. It is designed to understand the meaning of your query and can therefore return more accurate results more quickly.
How does SEMA work?Sema is built by SDU Analytics in Python and uses two technologies for its search function: BM25, which matches your words with the content of each report, and semantic search, which understands the meaning of your query and finds reports on the same topic even when different words are used. Sema combines the two methods and assigns an overall score to each report. The most relevant results appear at the top, so you can find the right web reports faster. As an AI agent, Sema evaluates your query, chooses the best search method and explains why it selected the results. You can ask questions in plain English and get clear answers. This provides a better experience than a standard search box because the results are easier to understand and act on.
Sema on SDU’s Analysis Portal
You can find Sema as the red AI symbol on the front page of SDU’s Analysis Portal, in the bottom right-hand corner.
Sema is the first of several AI Agents that SDU Analytics is developing. The upcoming AI Agents from SDU Analytics focus on solving specific analytical tasks, such as finding concrete information and delivering data visualisations for example for PowerPoints in SDU’s brand colours.
