Abstract： The publication ethics is the foundation and prerequisite for the development of scientific journals． Against the backdrop of vigorously promoting the construction of world-class scientific journals in China，the standardization construction of publication ethics is particularly urgent．As an important component of scientific research integrity，the standardization construction of publication ethics in scientific journals should comply with national policy requirements． This article comprehensively collected relevant policies on publication ethics in China，and through quantitative analysis of policy literature and grounded theoretical analysis，clarified the evolution of scientific journals publication ethics policies，the theoretical model for the standardization of publication ethics，and the changes in the content of publication ethics policies． Through the analysis of research results， it can be concluded that China is attaching increasing importance to the integrity and ethical governance of scientific journals; the basic framework for the standardization construction of publication ethics in scientific journals includes the overall requirements，the content of publication ethics， and the measures to ensure the implementation of publication ethics，of which the latter two are the key elements．

Abstract：【目的】从大规模食品安全事件当中抽取食品安全事件实体。【方法】基于已发生的食品安全事件, 结合情报学数据获取、标注和组织的方法, 融合食品安全事件实体的多种分布特征知识, 通过条件随机场模型, 构建食品安全事件语料并从中抽取相应的实体。【局限】在食品安全事件实体抽取过程中所制定的特征模板在领域化迁移上具有一定的局限性。【结果】在已有1500万字经过标注的食品安全事件语料的规模上, 通过统计食品安全事件实体的内部和外部特征, 基于条件随机场机器学习模型, 构建了食品安全实体的抽取模型, 该模型最高的F 值达到91.94%。【结论】通过对食品安全事件实体抽取结果的分析, 在食品这一领域化的语料上, 基于条件随机场进行实体抽取是可行的。
