在线问诊 Python、FastAPI、Neo4j — 问题咨询
通过节点关系,找出对应的节点,获取节点属性值,并拼接成想要的结果。
接上节生成的CQL
# 输入
question_class = {'args': {'看东西有时候清楚有时候不清楚': ['symptom']}, 'question_types': ['symptom_disease']}
# 输出
[{'question_type': 'symptom_disease', 'sql': ["MATCH (m:Disease)-[r:has_symptom]->(n:Symptom) where n.name = '看东西有时候清楚有时候不清楚' return m.name, r.name, n.name"]}]
# 输入:
question_class = {'args': {'干眼': ['disease']}, 'question_types': ['disease_drug']}
# 输出:
[{'question_type': 'disease_drug', 'sql': ["MATCH (m:Disease)-[r:used_drugs]->(n:Drug) where m.name = '干眼' return m.name, r.name, n.name,n.usage_dosage,n.generic_name,n.contraindications"]}]
# 输入:
question_class = {'args': {'干眼': ['disease']}, 'question_types': ['disease_not_food']}
# 输出:
[{'question_type': 'disease_not_food', 'sql': ["MATCH (m:Disease)-[r:noteat_foods]->(n:Foods) where m.name = '干眼' return m.name, r.name, n.name"]}]
查出节点
def search_main(self, sqls):
"""执行cypher查询,并返回相应结果"""
final_answers = []
for sql_ in sqls:
question_type = sql_['question_type'] # 'question_type': 'symptom_disease'
queries = sql_['sql'] # 'sql': ["MATCH (m:Disease)-[r:has_symptom]->(n:Symptom) where n.name = '看东西有时候清楚有时候不清楚' return m.name, r.name, n.name"]
answers = []
for cql in queries:
ress = neo4j.execute_query(cql) # logging.info("%s, %s", record["p"]["name"], record["p"]["generation"])
answers += ress
final_answer = self.answer_prettify(question_type, answers)
if final_answer:
final_answers.append(final_answer)
return final_answers
拼接节点属性
def answer_prettify(self, question_type, answers):
if question_type == 'symptom_disease':
desc = [i['m.name'] for i in answers]
subject = answers[0]['n.name']
final_answer = '{0}可能是:{1}'.format(subject, ';'.join(list(set(desc))[:self.num_limit]))
if question_type == 'disease_drug':
desc = []
for i in answers:
desc.append(i['n.name'] + "(" + i['n.generic_name'] + ")" + " 【用法用量】:" + i['n.usage_dosage'] + " 【禁忌】:" + i['n.contraindications'])
subject = answers[0]['m.name']
