How can text data be quickly and accurately processed?

挑战

The Medical Expenditure Panel Survey (MEPS), funded by the Agency for Healthcare 研究 and Quality (AHRQ), is a set of large-scale surveys of families and individuals, and their medical providers across the U.S.

超过20个,000 open-ended comments are entered by the interviewers each year into the MEPS computer-assisted personal interviewing (CAPI) system to clarify the respondents’ answers.

然后, a group of human coders reviews each sentence to assign a topic label to the sentences out of 10 predefined classes, and use the associated procedures to further process the data. 也, MEPS is a panel study and there is a short time window, 通常一周, to process the comments so that the data can get back to the field staff for use for dependent interviewing in the next wave. Processing this data is labor intensive and time consuming.

趣赢平台 harnessed the power of artificial intelligence (AI) capabilities to make the process more timely and efficient.

解决方案

趣赢平台 uses natural language processing (NLP), 机器学习(ML), and deep learning techniques to train a classification model to automatically label the comments into 10 predefined classes.

We then deploy the model as a RESTful API in production so that it can run in the backend of the system used by the human coders. The model suggests the top 3 classes for each sentence ranked by classification probability, which allows human coders to make a selection out of 3 rather than 10 when reviewing the comments.

结果

The data tool has been in production for the past 2 data collection periods in 2020. The tool achieved more than 95% classification accuracy for the top suggestion in processing 10,000+ comments for each round, with an efficiency gain of about 5% and reducing backlog to virtually zero.
