pythia's Issues

Improve control over scoring weights

Provide a better way to balance the effects of the score components.
Currently, the static and dynamic weights do not provide optimal results in all cases.

Entity identification

Add entity identification by any means to improve result quality and reduce the number of duplicates.

Automate and visualize evaluation

Add automated evaluation:

  • select appropriate quality measures
  • visualize evaluation on the frontend
  • update evaluation async in the background on scoring function adjustments

Improve top candidates cut off

Current scheme to cut off by a set percentage of the exponential moving average does not provide optimal results in some cases.

Evaluate semantic results

Phase 2 results as returned by Broccoli need to be evaluated and results displayed jointly with the phase 1 results.

Customizable scoring functions

Provide an interface for custom scoring functions.
Currently scoring functions are hard coded in script.js and the backend.

Establish ground truth

Provide a ground truth for query to result entities and from query to result semantic query.

Include important verbs in semantic query

Verbs which describe an important relation between the entities should be included in the semantic query, while common verbs like is should be ignored.

Consider simple verb form conversion.
