Pre-1950 Serials in OCLC

To investigate the use by OCLC member institutions of database records for pre-1950 serial publications and to compare the value of those records with the ones in the long standard Union List of Serials and the newly completed National Union Catalog, Pre-1956 Imprints, a residue of 50 titles found in a random sample of 200 serials drawn from OCLC in 1978 were examined in the database again in 1981 and searched in the printed tools. The 2 OCLC records were compared to find bibliographical modifications, last time of use, and additional libraries reported. The 1981 record was compared against records from ULS and NUC Pre-1956 for the number of libraries with ownership reported and the inclusion of selected bibliographical data. OCLC participants had made some use of more than half the records and appeared to be updating the bibliographical content as necessary. Almost all the titles were in one of the printed tools, but a substantial number were not in both. NUC Pre-1956 carried more of the titles than ULS, but ULS appeared to be the most comprehensive of the 3 tools for those serials it listed. OCLC followed ULS as a bibliographical resource while NUC Pre-1956 came second for identifying holding libraries. OCLC was concluded to have strength and potential as a pre-1956 serial information tool by its capacity to correct and add data while ULS and NUC Pre-1956 were concluded to be valuable backup sources for the older serial publications also having an online record available.

合理创建索引 实现数据库访问的优化

数据库访问的效率是决定应用系统执行效率的关键因素之一.索引的设计应建立在对各种查询的分析和预测上.通过在Microsoft SQL Server 2008上对四种索引方案的测试,提出了利用索引优化数据查询的方法.在实际应用时,要根据系统的实际情况,权衡修改性能和检索性能的需求,选用合理的索引策略.     

Using computer vision techniques on Instagram to link users’ personalities and genders to the features of their photos: An exploratory study

Instagram and other photo-based social networking sites have emerged as a popular medium. Previous studies mainly focused on social media texts, but the current study deals with the relationships between the characteristics of Instagram users and the features of their photos. The Big Five personality traits and gender were employed as the variables for user characteristics. Content category, the number of faces, the emotions on the faces, and the pixel derived features were employed as the variables for photo characteristics. An online survey of 179 university students was conducted to measure user characteristics, and 25,394 photos in total were downloaded and analyzed from the respondents’ Instagram accounts. Results suggested that content category is associated with extraversion and gender of users. The number of faces is associated with extraversion, agreeableness, and openness of users. Extraversion, agreeableness, and openness of users were partly associated with emotions expressed on the faces in their photos. Correlations were observed among some pixel features and extraversion, agreeableness, conscientiousness, and gender of users. It was also observed that the Big Five personality traits, except for gender, can be predicted by above variables. Implications and limitations are discussed and suggestions for future research are suggested.     

基于微软学术搜索的信息检索研究的文献计量分析

以微软学术搜索为数据获取工具,对微软、谷歌和雅虎三个机构在信息检索领域的研究成果的数量、研究主题和研究人员的等状况进行比较研究。研究发现,微软在各个方面都是表现最好的;谷歌在被引方面的表现是最好的;雅虎在研究成果数量和研究人员数量方面多于谷歌,少于微软,其被引在三个机构中相对较弱。可以说,研究主题和研究人员的兴趣方面,三个机构各有特色。
