Gliner Small V2.5

🚀 GLiNER - 通用命名实体识别模型

GLiNER是一个命名实体识别（NER）模型，它能够使用双向变压器编码器（类似BERT）识别任何实体类型。该模型为传统的NER模型提供了一个实用的替代方案，传统模型仅限于预定义的实体，而大语言模型（LLMs）虽然灵活，但在资源受限的场景下成本高且规模大。

🚀 快速开始

GLiNER是一个强大的命名实体识别模型，能够识别各种实体类型。下面将为你介绍如何安装和使用该模型。

✨ 主要特性

• 实体类型识别广泛：能够识别任何实体类型，突破了传统NER模型只能识别预定义实体的限制。
• 成本效益高：相较于大语言模型，在资源受限的场景下，具有更好的成本效益。
• 灵活性强：基于双向变压器编码器（类似BERT）构建，具有较强的灵活性。

📦 安装指南

要使用此模型，你必须安装GLiNER Python库：

!pip install gliner -U

💻 使用示例

基础用法

from gliner import GLiNER

model = GLiNER.from_pretrained("gliner-community/gliner_small-v2.5", load_tokenizer=True)

text = """
Cristiano Ronaldo dos Santos Aveiro (Portuguese pronunciation: [kɾiʃˈtjɐnu ʁɔˈnaldu]; born 5 February 1985) is a Portuguese professional footballer who plays as a forward for and captains both Saudi Pro League club Al Nassr and the Portugal national team. Widely regarded as one of the greatest players of all time, Ronaldo has won five Ballon d'Or awards,[note 3] a record three UEFA Men's Player of the Year Awards, and four European Golden Shoes, the most by a European player. He has won 33 trophies in his career, including seven league titles, five UEFA Champions Leagues, the UEFA European Championship and the UEFA Nations League. Ronaldo holds the records for most appearances (183), goals (140) and assists (42) in the Champions League, goals in the European Championship (14), international goals (128) and international appearances (205). He is one of the few players to have made over 1,200 professional career appearances, the most by an outfield player, and has scored over 850 official senior career goals for club and country, making him the top goalscorer of all time.
"""

labels = ["person", "award", "date", "competitions", "teams"]

entities = model.predict_entities(text, labels)

for entity in entities:
    print(entity["text"], "=>", entity["label"])

输出示例

Cristiano Ronaldo dos Santos Aveiro => person
5 February 1985 => date
Al Nassr => teams
Portugal national team => teams
Ballon d'Or => award
UEFA Men's Player of the Year Awards => award
European Golden Shoes => award
UEFA Champions Leagues => competitions
UEFA European Championship => competitions
UEFA Nations League => competitions
Champions League => competitions
European Championship => competitions
