[研究目的]引导式主题模型可以引导生成有倾向性的敏感主题,提高网络敏感信息识别性能,对维护国家安全和社会稳定具有重要意义。[研究方法]针对当前网络敏感信息识别研究构建敏感信息特征不全面和不准确,从而导致识别性能欠佳的问题,提出基于SSI-GuidedLDA模型的引导式网络敏感信息识别方法。首先,从多源网络资源中爬取敏感种子词,并基于词向量模型Word2Vec获得种子词的敏感语义相关词,构建更为完备、准确的敏感特征。其次,将构建的敏感特征融入引导式主题模型,得到改进后的模型SSI-GuidedLDA。最后,基于SSI-GuidedLDA模型获得待识别信息的主题分布,通过主题分布概率判断其是否为网络敏感信息。[研究结论]在新浪微博数据集上的实验结果显示,与已有方法相比,提出的方法在准确率、召回率和F 1值上均有一定提高。 展开更多

Tourist guide,which is a special type,practically makes details of the arrangement with journey as well as gives orders to tourists. Tour guide,as a commander and a server,is closely related to tourists who are customers as well as carrying out orders. So the orders of tourist guide should be given po-litely under this special relationship. In order to understand the polite expression of giving order,this paper makes analysis on a tourist guide from the perspective of interpersonal metafunction,especially from Mood and Modality. 展开更多

Endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA) is a useful and relatively safe tool for the diagnosis and staging of pancreatic cancer. However, there have recently been several reports of tumor seeding after EUS-FNA of adenocarcinomas. A 78-year-old man was admitted to our hospital due to upper gastric pain. Examinations revealed a 20 mm mass in the pancreatic body, for which EUS-FNA was performed. The cytology of the lesion was adenocarcinoma, and the stage of the cancer was T3N0M0. The patient underwent surgery with curative intent, followed by adjuvant chemotherapy with S-1. An enlarging gastric submucosal tumor was found on gastroscopy at 28 mo after surgery accompanied by a rising level of CA19-9. Biopsy result was adenocarcinoma, consistent with a pancreatic primary tumor. Tumor seeding after EUS-FNA was strongly suspected. The patient underwent surgical resection of the gastric tumor with curative intent. The pathological result of the resected gastric specimen was adenocarcinoma with a perfectly matched mucin special stain result with the previously resected pancreatic cancer. This is the first case report of tumor seeding after EUS-FNA which was surgically resected and inspected pathologically. 展开更多
