Abstract
Embodiments may provide a document system that receives a responsiveness call from a user through the task/queue framework regarding a machine call document. Theses responsiveness calls may be used to refining the scoring algorithm used by the document system of to generate a desired confidence score for the document system.
Claims24
An electronic document system, comprising:
- a processor;
- a non-transitory computer readable medium, comprising instructions for:
- selecting a control set of documents from a plurality of documents in a data store;
- presenting the control set of documents to a user;
- receiving an indicator of responsiveness for each of the documents of the control set of documents;
- and instructions for causing the document system to perform the steps of:
- a) determining a responsiveness score for each of the plurality of documents according to a scoring algorithm including determining a document responsiveness probability for the document, determining a weighted topic score for the document for each of a set of topics in a topic-related generative model based on the document responsiveness probability and a topic-document weight between the topic and the document, generating an initial responsiveness score based on the topic-document weights of the document for each topic and the weighted topic score, and normalizing the document responsiveness probability based on the initial responsiveness score to determine the responsiveness score for the document;
- b) determining a set of responsive documents of the plurality of documents based on the responsiveness score determined for each of the plurality of documents and the decision boundary score;
- c) determining a confidence score for the document system using the responsiveness score for each of the documents of the control set and the indicator of responsiveness for each of the control set documents received from the user;
- d) selecting one or more of the plurality of documents based on the responsiveness scores of the plurality of documents;
- e) presenting the one or more selected documents to the user;
- f) receiving the indicator of responsiveness from the user for each of the selected documents;
- g) refining the scoring algorithm based on the indicator of responsiveness for each of the selected document;
- and
- h) generating a desired confidence score for the document system and presenting the set of responsive documents to the user when the desired confidence score for the document system is achieved, wherein the confidence score for the document system is determined by comparing the responsiveness score for the documents of the control set to the indicator of responsiveness for the documents of the control set received from the user or by comparing the responsiveness score for the selected documents to the indicator of responsiveness for the selected documents received from the user.
