The problem addressed in this paper is that of simplifying access point determination. A critique is made of the simple, mechanical rule whereby every name appearing in certain designatable locations within a publication qualifies as an access point. Then a more acceptable version of the every-name-an-access-point rule is tested empirically against a sample of 400 English language monographs. Conclusions reached concern (1) the responsibility profiles of these monographs, i.e., how many authors, editors, illustrators and emanators are typically associated with them and in what combinations, and (2) the relative productivity of different locations within them, e.g., title pages and tables of contents, as sources of access points. The study was conceived to be exploratory in nature and its findings suggest further research that could be done to provide empirical validation for rules for access point determination. 相似文献

The article provides an outline from an historical standpoint of how Italian cataloging rules have dealt with serials and gives a general picture of the current situation and trends. The most recent of the three national codes issued up to the present lime (1921,1956, and 1979) recommends the creation of a separate catalog for this type of publication in conformity with a national standard (UNI norm 6392) conceived outside the framework of the functions of the general library catalog. There exists, however, a substantially uniform cataloging tradition that allows access by title and deals with title changes in accordance with the principle of successive entry. The only existing national periodical file was created by the Istituto di studi sulla ricerca e documentazione scientifica (ISRDS) of the Consiglio nazionale delle ricerche (CNR), set up in conformity with UNI norm 6392. The existence of this file, whose records are to be adapted and converted, forms the basis of a government project to create a periodical file within the catalog of the National Library Service (SBN). 相似文献

[目的/意义]为帮助用户检索到完整的、粒度大小适当的知识单元，满足用户多粒度的知识需求。[方法/过程]提出一种基于知识元的文本层级分割方法。该方法首先对知识元的类型及其描述规则进行分析；然后依据知识元描述规则识别实体资源中的各类型知识元，并将所有的知识元和知识元之间的衔接句视为一个类；最后基于fisher分割算法对该类进行逐级二分，直到识别出所有的主题为止，确定分割边界，实现文本层级分割。[结果/结论]基于知识元的中文文本层级分割方法，一方面使得文本分割单元从句子扩展为知识元，提高分割时的效率，另一方面将知识服务的控制单元从文献深入到以知识元、知识元集合为单位的知识块，按需为用户提供相关知识服务，使数据检索、信息检索向知识检索迈进，提高知识获取效率，实现信息服务向知识服务的转型。 相似文献

New forms of publication have called into question AACR2’s current division of the type of publication into monographs and serials. This paper analyzes the recommendations in the April 1999 report to the Joint Steering Committee (JSC) on AACR, “Revising AACR2 to Accommodate Seriality.” The JSC report presents a new type of publication model, which recognizes elements of seriality in resources that do not meet the current AACR2 definition of serial. Recommendations in the JSC report attempt to provide rules for the cataloging of new forms of materials as well as solutions to other current cataloging problems. Some of these solutions are based on incorporating and adapting the best of former rules and practices. Anticipated benefits of the rule revision include harmonization of AACR2 with international standards, reduction of needless title changes, and a more holistic approach to serials cataloging. 相似文献

针对高校图书馆场景存在的无显式反馈、借阅数据稀疏和传统推荐算法效果不好问题,提出基于时间上下文优化协同过滤的推荐算法,包含读者阅读行为评分、时间上下文和内容兴趣变迁3个要素。在数据准备阶段,通过制定评分转化规则、设计标准化函数来构建一种基于用户行为操作的兴趣评分模型,以解决用户评分缺失问题;在推荐召回阶段,提出一种非线性的时间衰减模型来对评价矩阵进行优化,以提高推荐效果;在推荐排序阶段,提出一种兴趣捕捉模型对召回结果按照图书类别进行精排序,以缓解数据稀疏问题并进一步提高推荐效果。实验结果表明,文章提出的优化算法在Top5的F值较未经优化的协同过滤提升增幅达141%。 相似文献

This study explores means of coping with the increase in homonymous personal name files in authority control systems. To improve the accuracy with which such files are distinguished, we suggest developing systematic rules for handling additional components—elements frequently, but inconsistently, associated with personal name authority files in various authority control schemes. We describe the general usage of these components for Chinese personal names, along with the influence of these use patterns on the quality of name authority files. To illustrate our points, we offer a statistical analysis of the top 100 personal names (i.e., those with the greatest number of homonymous entries) from the name duplication list in the three most influential databases in China: HKCAN, NLC and CALIS. Statistics of name duplication, along with type and use frequency of additional components, are described and analyzed. We also analyze the discriminating power of three frequently-used types of additional information. Finally, we point out various issues which have impeded the broader and more systematic use of additional components. 相似文献

[目的/意义]控制标题字符长度、运用特殊标点符号、进行标题数字化等微信运营策略已经被高校图书馆普遍应用,但却不能满足现阶段高校图书馆微信精细化运营的需要。从实务操作层面,斟酌标题文本的文字、控制字符长度、使用特殊标点和区分数字标题的应用场景和环境变得尤为迫切。[方法/过程]选取入围2018年4月15日-28日WCI榜单前50名的29所高校图书馆的524篇标题文本作为研究数据,为了提高数据的代表性与验证结论的可信性,增加对2019年11月榜单、2020年4月15日-28日榜单部分文本数据的分析,结合文本分析法、比较分析法、调研对象访谈等方法,结合网络传播环境下把关人的理论要素,对微信标题文本的内容要素(文字、主题)和形式要素(数字、标点和长度)进行分析,寻找帮助图书馆微信文案从海量信息中脱颖而出的方法,从而实现营销效果的提升。[结果/结论]构建出一套适合高校图书馆特点的微信标题精准运营策略公式,即从内容本位出发,提取关键新闻要素,对关键新闻要素进行优先级排序,在关键新闻要素中寻找"小切口"突出标引,增加形式要素的技巧,营造持续稳定的新鲜感。 相似文献

XML retrieval is a departure from standard document retrieval in which each individual XML element, ranging from italicized words or phrases to full blown articles, is a retrievable unit. The distribution of XML element lengths is unlike what we usually observe in standard document collections, prompting us to revisit the issue of document length normalization. We perform a comparative analysis of arbitrary elements versus relevant elements, and show the importance of element length as a parameter for XML retrieval. Within the language modeling framework, we investigate a range of techniques that deal with length either directly or indirectly. We observe a length-bias introduced by the amount of smoothing, and show the importance of extreme length bias for XML retrieval. We also show that simply removing shorter elements from the index (by introducing a cut-off value) does not create an appropriate element length normalization. Even after restricting the minimal size of XML elements occurring in the index, the importance of an extreme explicit length bias remains. 相似文献

数据成为新型生产要素,如何实现数据要素的优化配置是数据经济发展的关键环节。数据交易是数据要素流动的重要通路,2020年《数据安全法(草案)》首次在法律层面提出要建立健全数据交易管理制度,规范数据交易行为,培育数据交易市场。在此背景下,应以利益均衡为基点对传统基本原则进行反思和再阐释,搭建数据权益保护和数据产业激励双层维度的基本规制原则。前者以知情同意原则、责任和安全保护原则为双足;后者以区分规制原则、合理使用原则为两翼,由此形成"保护-激励"双层维度的平衡性制度安排。 相似文献

Relating rhetoric to power, this essay offers a view of power as communication medium, i.e., communication through power. Logically prior, however, is power through communication by which the rules for power are rhetorically derived. Case studies show (1) a conception of rhetoric‐as‐power being complementary to rhetoric‐as‐epistemic; (2) the development of the power medium as a cultural code dependent on hierarchical interdependency; and (3) the formal strategies, tactics, and maneuvers of rhetoric‐as‐power for social intervention. 相似文献
