The CrowdTruth Framework implements an approach to machine-human computing for collecting annotation data on text, images and videos. The approach is focussed specifically on collecting gold standard data for training and evaluation of cognitive computing systems. The original framework was inspired by the IBM Watson project for providing improved (multi-perspective) gold standard (medical) text annotation data for the training and evaluation of various IBM Watson components, such as Medical Relation Extraction, Medical Factor Extraction and Question-Answer passage alignment.
The CrowdTruth framework supports the composition of CrowdTruth gathering workflows, where a sequence of micro-annotation tasks can be configured and sent out to a number of crowdsourcing platforms (e.g. CrowdFlower and Amazon Mechanical Turk) and applications (e.g. Expert annotation game Dr. Detective). The CrowdTruth framework has a special focus on micro-tasks for knowledge extraction in medical text (e.g. medical documents, from various sources such as Wikipedia articles or patient case reports). The main steps involved in the CrowdTruth workflow are: (1) exploring & processing of input data, (2) collecting of annotation data, and (3) applying disagreement analytics on the results. These steps are realised in an automatic end-to-end workflow, that can support a continuous collection of high quality gold standard data with feedback loop to all steps of the process. Have a look at our presentations and papers for more details on the research.
An encouraging quote from Truth is a Lie by Lora Aroyo.
the idea of truth is a fallacy for semantic interpretation and needs to be changed
I don’t disagree but observe a “crowdtruth” with disagreements is a variant of “truth.” What variant of “truth” is of interest to your client is an important issue.
CIA analysts, for example, have little interest in crowdtruths that threaten their prestige and/or continued employment. “Accuracy” is only one aspect of any truth.
If your client is sold on crowdtruths, by all means take up the banner on their behalf. Always remembering:
There are no facts, only interpretations. (Nietzsche)
Which interpretation interests you?
