Spatial Discovery of Linked Research Datasets and Documents at a Spatially Enabled Research Library

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future.

Comparison and Classification of Documents Based on Layout Similarity

This paper describes features and methods for document image comparison and classification at the spatial layout level. The methods are useful for visual similarity based document retrieval as well as fast algorithms for initial document type classification without OCR. A novel feature set called interval encoding is introduced to capture elements of spatial layout. This feature set encodes region layout information in fixed-length vectors by capturing structural characteristics of the image. These fixed-length vectors are then compared to each other through a Manhattan distance computation for fast page layout comparison. The paper describes experiments and results to rank-order a set of document pages in terms of their layout similarity to a test document. We also demonstrate the usefulness of the features derived from interval coding in a hidden Markov model based page layout classification system that is trainable and extendible. The methods described in the paper can be used in various document retrieval tasks including visual similarity based retrieval, categorization and information extraction.     

种子概念方法及其在基于文本的本体学习中的应用

介绍基于文本的本体学习及其层次,分析本体学习中术语获取的主要方法。针对术语获取中存在的问题,在术语形成的经济规律基础上,引入种子概念方法,并利用统计和规则两种方法抽取与种子概念相关的领域术语;证明种子概念方法是一种有效获取领域术语的方法。实验证明少量种子词可以获取大量领域术语,为本体构建提供基础和框架。     

期刊PR8指数:一个新的跨学科期刊评价指标及其实证研究

[目的/意义] 基于论文被引频次8个区段百分位数排序（percentile rank 8,PR8）赋分,尝试构建新的跨学科期刊评价指标：期刊PR8指数（journal index for PR8,JIPR8）,并检验JIPR8的跨学科期刊评价效果。[方法/过程] 选择JCR中8个学科301种期刊作为研究对象,分别计算每种期刊的JIPR8,并与其他几个跨学科期刊评价指标进行比较,检验JIPR8跨学科期刊评价的敏感度和稳定性,以及与其他跨学科期刊评价指标的相关性。[结果/结论] 在选择的所有指标中,8个学科301种期刊JIPR8的变异程度最低,说明其用于跨学科期刊评价的稳定性最好;不同分区期刊（Q1、Q2、Q3和Q4） JIPR8的组间差异性较为明显,仅次于期刊影响因子百分位（journal impact factor pencentile,JIFP）,表明其对优秀和一般期刊的区分度较好。认为JIPR8是一个非常理想的跨学科期刊评价指标。
