A Testbed for Dual-Entity Knowledge Panels

Summary • Usage • Contributing • License

Summary

The current presentation of knowledge panels in web search engines is limited to displaying summarized information only when a query refers to a single entity. This repository contains a testbed for developing and evaluating dual-entity knowledge panels. The idea is to populate these novel knowledge panels with an explanation of the relationship between the entities of queries mentioning two of them. Previous research has demonstrated the ability to identify paths in Wikidata that connect any two entities, offering a valuable foundation for explaining their relationship. However, little research has been done on how to effectively present these paths in a user-friendly manner within this context. Therefore, this repository features a few pre-implemented presentation formats, such as graph-based visualizations and text-based approaches utilizing language models, to encourage further investigation in this area.

Usage

Only the docker and docker compose scripts are required to run the testbed. All dependencies are automatically installed using the corresponding Dockerfiles. This ensures reproducibility and ease of use. For guidance on how to install Docker click here. To run the testbed, execute the following commands via a command line within this folder:

1. docker compose build
2. docker compose run --service-ports panels

Via the command line of the container run:

3. npm install
4. npm run dev

When the testbed is running, it can be accessed at http://localhost:3000.

Contributing

Regarding technologies, the testbed mainly builds upon the following:

• Vite
• Svelte
• Bootstrap

If you are not familiar with Svelte and/or Bootstrap, we recommend to have a look at their documentation before you start implementing. To implement additional presentation formats for the dual-entity knowledge panels, proceed as follows:

1. Add another svelte file in the formats folder with an appropriate name for your presentation format. This file will contain almost all your code. To start off, feel free to copy one the code from one of the other components within this folder.
2. In the stores.js file add a string representing the label referring to your presentation format in the formats array.
3. In the lower part of the Panel.svelte file, there is an if statement that maps the labels of the presentation formats to their corresponding svelte component. Following the shown pattern, add another else if statement to map the label you added in the formats array to the component you created in the first step. Don't forget to import your component in the top of the Panel.svelte file.
4. Reload/start the application if necessary. You should now be able to select your presentation format via the same dropdown menu as the other presentation formats.
