python示例代码：

import textrazor textrazor.api_key = "c3c38227a0e458e6095dce1e6ff54d4ae9e2584e91c9be8d26e132d3" client = textrazor.TextRazor(extractors=["entities", "topics"]) response = client.analyze("I like basketball, and I also like to sing.") print(response.topics()) for entity in response.entities(): print(entity.id, entity.relevance_score, entity.confidence_score, entity.freebase_types)

结果展示

Basketball 0 1.49 ['/fictional_universe/fictional_organization_type', '/interests/interest', '/sports/school_sports_team', '/book/book_subject', '/cvg/computer_game_subject', '/organization/organization_sector', '/media_common/media_genre', '/broadcast/genre', '/sports/sports_team', '/interests/hobby', '/olympics/olympic_sport', '/cvg/cvg_genre', '/award/competition_type', '/award/award_discipline', '/film/film_subject', '/law/invention', '/media_common/netflix_genre', '/education/field_of_study', '/sports/sport']

可以看到 会对篮球这个实体进行分析，得到与篮球相关联的实体

上述是实体识别，不是分类

真正的api分类
