Evaluation Data and Benchmarks for Cascaded Speech Recognition and Entity Extraction

Abstract During clinical handover, clinicians exchange information about the patients and the state of clinical management. To improve care safety and quality, both handover and its documentation have been standardized. Speech recognition and entity extraction provide a way to help health service providers to follow these standards by implementing the handover process as a structured form, whose headings guide the handover narrative, and the documentation process as proofing and sign-off of the automatically filled-out form. In this paper, we evaluate such systems. The form considers the sections of Handover nurse, Patient introduction, My shift, Medication, Appointments, and Future care, divided in 49 mutually exclusive headings to fill out with speech recognized and extracted entities. Our system correctly recognizes 10,244 out of 14,095 spoken words and regardless of 6,692 erroneous words, its error percentage is significantly smaller than for systems submitted to the CLEF eHealth Evaluation Lab 2015. In the extraction of 35 entities with training data (i.e., 14 headings were not present in the 101 expert-annotated training documents with 8,487 words in total), the system correctly extracts 2,375 out of 3,793 words in 50 test documents after calibration on 3,937 words in 50 validation documents. This translates to over 90% F1 in extracting information for the patient's age, current bed, current room, and given name and over 70% F1 for patient's admission reason/diagnosis and last name. F1 for filtering out irrelevant information is 78%. We have made the data publicly available for 201 handover cases together with processing results and code and proposed the extraction task for CLEF eHealth 2016.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
