ChineseBLUE, the Chinese Biomedical Language Understanding Evaluation benchmark

License GitHub stars GitHub forks

This repository includes the data of the WSDM 2020 Healthcare Day paper Conceptualized Representation Learning for Chinese Biomedical Text Mining.

We also recommmend to use our recent released CBLUE benchmark which includes a collection of natural language understanding tasks including named entity recognition, information extraction, single-sentence/sentence-pair classification, and an associated online platform for model evaluation, comparison, and analysis.

Introduction

ChinesseBLUE benchmark consists of different biomedicine text-mining tasks with corpora. These tasks cover a diverse range of text genres (biomedical web data and clinical notes), dataset sizes, and degrees of difficulty and, more importantly, highlight common biomedicine text-mining challenges.

MC-BERT is a novel conceptualized representation learning approach for the medical domain. First, we use a different mask generation procedure to mask spans of tokens, rather than only random ones. We also introduce two kinds of masking strategies, namely whole entity masking and whole span masking. Finally, MC-BERT split the input document into segments based on the actual "sentences" provided by the user as positive samples and sample random sentences from other documents as negative samples for the next sentence prediction.

Named Entity Recognition (NER)

Named entity recognition aims to recognize various entities, including diseases, drugs, syndromes, etc. The cEHRNER dataset labeled from the Chinese electronic health records and the cMedQANER dataset labeled from Chinese community question answering is chosen.

Paraphrase Identification (PI)

Paraphrase Identification aims to identify whether two sentences express the same meaning. We use cMedQQ, which consists of search query pairs.

Question Natural Language Inference (QNLI)

Question natural language inference aims to identify whether the answer corresponds to the question in the question-answering pair. We use cMedQNLI, which consists of question-answer pairs.

Question Answering (QA)

Question answering can be approximated as ranking candidate answer sentences based on their similarity. We assign 0,1 labels to the QA pairs, which convert to the binary classification problem. We use cMedQA released from the paper "Multi-Scale Attentive Interaction Networks for Chinese Medical Question Answer Selection", which consists of questions and their answers.

Information Retrieval (IR)

Information retrieval aims to retrieve most related documents given search queries. IR can be regarded as a ranking task. We use the cMedIR dataset, which consists of queries with multiple documents and their relative scores.

Intent Classification (IC)

Intent classification aims to assign intent labels to the queries, which can be regarded as multiple label classification tasks. We use the cMedIC dataset, which consists of queries with three intent labels (e.g., no intention, weak intention, and firm intention).

Text Classification (TC)

Text classification aims to assign multiple labels to the sentence. We use the cMedTC dataset, which consists of biomedical texts with multiple labels.

Symptom Diagnosis

Symptom diagnosis is a challenging yet profound problem in natural language processing. We use the CMDD dataset released from the paper"Enhancing Dialogue Symptom Diagnosis with Global Attention and Symptom Graph".

Relation extraction (RE)

Coming soon.
