新建地方本科院校视觉识别系统评价体系构建研究——以怀化学院为例

通过对问卷中的数据进行因子分析和处理,找出了在怀化学院视觉识别系统建设中起重要影响作用的因素,确定了视觉识别系统评价指标内容和结构。并进一步计算各因子方差贡献率和因子负荷量在总量中的比例,确定了指标的权重,最终建立了怀化学院视觉识别系统评价指标评价指标体系。     

二叉排序树上删除结点算法的研究

详细分析了文献[1]中二叉排序树的查找、插入、删除操作。文献[1]先是实现了查找算法,调用查找算法实现插入操作,当查找不成功时插入结点。对于删除操作,是在二叉排序树上查找成功时删除结点,并详细描述了删除结点时的三种情况,其中分析了双亲结点指针的变化,而在具体实现时没有像插入操作那样直接调用查找算法,而是借助于递归和引用控制删除结点和双亲结点的关系及双亲结点指针的变化,在查找的过程中实现删除,边查找边删除。这种不一致性给很多读者带来了疑惑。该文针对该问题提出基于查找算法的删除算法,该算法显式地体现了删除结点时双亲结点指针的变化,一方面和文字描述部分一致,同时又和插入操作具有统一性,便于读者更好地理解二叉排序树上的删除操作。     

基于树型结构的数据库管理软件设计

数据库的可视化管理和状态监控在数据库的开发与维护中起到重要的作用,设计一种基于树型结构的友好的用户操作界面,包括数据库的连接、数据库中表、视图、存储过程的各种操作到数据库与表的监控,使得数据库的状态信息和操作过程更加直观.实践表明基于用户友好界面的数据库管理软件有很好地实用性和有效性.     

Perceptual Literacy and the Construction of Significant Meanings within Art Education

In order to verify how important the ability to process visual images and sounds in a holistic way can be, we developed an experiment based on the production and reception of an art work that was conceived as a multi‐sensorial experience and implied a complex understanding of visual and auditory information. We departed from the idea that to foster processes that encourage constructions of significant meanings it is necessary to abandon vision/audio‐centric notions of objecthood and offer a general definition of the perceptual object. The test was realised between the participants after modifying the performance conditions: some could not see the visuals, some could not hear the sound and others could appreciate the performance as a whole. Considering the results, we could infer that only the possibility to ‘read’ the performance as a whole encouraged construction of significant meanings. It would be possible to upgrade the approach, turning visual literacy into perceptual literacy, to contextualise artistic production that stimulates hybrid sensitive experiences. The education of critical perceivers should also enable transformations in responses to different stimuli. This is important if we consider the individuality of each student, his or her needs, affinities, cultural background, gender and so on.     

下一代目录在大学图书馆的应用

Automatic suggestion of phrasal-concept queries for literature search

Both general and domain-specific search engines have adopted query suggestion techniques to help users formulate effective queries. In the specific domain of literature search (e.g., finding academic papers), the initial queries are usually based on a draft paper or abstract, rather than short lists of keywords. In this paper, we investigate phrasal-concept query suggestions for literature search. These suggestions explicitly specify important phrasal concepts related to an initial detailed query. The merits of phrasal-concept query suggestions for this domain are their readability and retrieval effectiveness: (1) phrasal concepts are natural for academic authors because of their frequent use of terminology and subject-specific phrases and (2) academic papers describe their key ideas via these subject-specific phrases, and thus phrasal concepts can be used effectively to find those papers. We propose a novel phrasal-concept query suggestion technique that generates queries by identifying key phrasal-concepts from pseudo-labeled documents and combines them with related phrases. Our proposed technique is evaluated in terms of both user preference and retrieval effectiveness. We conduct user experiments to verify a preference for our approach, in comparison to baseline query suggestion methods, and demonstrate the effectiveness of the technique with retrieval experiments.
