Ontology patterns classification research is the first stage of understanding and the basis of patterns using. There are 3 kinds of Ontology patterns classification: the whole Ontology patterns Classification framework proposed by Blomqvist, NeOn, and the Ontology design patterns classification researched by the University of Manchester. This paper describes each kind topology by examples, then proposes existing questions and future work.

The paper conducts a comparative research on two international mainstream metadata packaging methods nowadays—VEO and METS in order to discover their advantages and disadvantages. It also suggests using METS as a replacement or complement of VEO as electronic records packaging method in our country to improve our electronic records packaging strategy, propelling and advancing the practice such as digital archives.

This paper introduces 6 pattern languages of website user interface, puts forward the evaluate criteria for pattern language of website user interface.Then it analyses the 6 pattern languages of website user interface comparatively, and points out some suggestions on how to write pattern languages of digital library website user interface in order to improve the usability of digital library.

Based on literature research and case studies, this paper makes an analysis on Freebase. It introduces the differences between Freebase and other semantic projects, studies the sources of Freebase, analyses its structure and features, and mainly focuses on the research of its knowledge representation and organization. This paper also explores the applications based on Freebase and the advices on how to use Freebase, which provides a thought to the research on advanced information technology as well.

To improve the efficiency of extracting sentiment words and building sentiment lexicon, the authors propose a method to extract a set of basic sentiment words, and then to calculate both the PMI-IR value between candidate word and the positive basic sentiment word set and the PMI-IR value between candidate words and the negative basic sentiment word set, to judge the orientation of a candidate word.Taking account of frequency, orientation, intensity and definiteness of words, computers are able to finish most of the work. It improves the efficiency and reduces cost of building sentiment lexicon. Experiment is processed on the dataset constituted with 71 061 reviews from 360buy and 1 736 reviews from Joyo. With the dataset, the method achieves a recall rate of 76.36%, a precision of 76.94%,and the precision of sentiment orientation is 62.70%.

Because of the characteristic of time-serial and polymorphism of the network information, this paper presents a model of extracting the complex time information based on Conditional Random Fields(CRF), and verifies the feasibility of this model through an experiment, compares the results through choosing the features of words (contexts) and word-POS. The experiment shows that the result will be much improved if adding the POS feature.

With 1987-2009 documents in Wanfang Data, the paper collects all documents of industrial technology. Within 16 second categories, it computes the keywords frequency, and calculates the standard deviation of keywords within relative categories. There are more than 50% keywords can be attributed to one category, and nearly 90% keywords can be put in 1-3 categories. If keywords belong to 3 or more than 3 categories, when the word frequency is less than 11, 16% of the words can be categorized; when word frequency is equal or greater than 11, and 49% of the words can be categorized. Test concludes that keywords can be classified by machine-aided with keyword frequency statistics and standard deviation, which is better than traditional classification method.

In order to meet the great demand of readers on academic videos, a key frame extraction algorithm on the features of academic videos is proposed. Based on shot segmentation and caption detection, the academic video quick scan scheme is realized, which is helpful for the rapid spread of library academic videos.

In this paper, empirical analysis on AIRSSM is carried out based on structural equation model.The results show that special emphasis of scholarly information retrieval systems analysis and design should be focused on: (1)System quality and information quality oriented; (2)A balanced consideration of all factors affecting system quality; (3)Authority, integrity, real-time and effectiveness are essential to information quality.

This paper firstly introduces the model and technology of text classification, especially analyzes and compares two methods of text semantic orientation based on both statistical and semantic analysis. Then it proposes pattern matching based on the extraction and text classification algorithm, and evaluate this algorithm. Finally, the authors describe the technical implementation and fields application of text semantic orientation.

Based on Maslow's hierarchy of needs theory, this paper makes a comparison study on the functions of elder's websites in China and the U.S.A to meet hierarchies of needs, finds that most of the elder's websites in China can provide four to five hierarchies of needs, while the elder's websites in the U.S.A can meet two to three hierarchies of needs. The design of elder's websites in the U.S.A is concentrated on two or three levels of services for elderly in depth, otherwise most of China's websites place more emphasis on comprehensive functions, emphasizing the promotion and advertising of services. Finally, the authors conclude that the design of elder's websites in China should be strengthened in readability, information display, multimedia, navigation and layout design, in order to increase the accessibilit.

The X-server is an Open API of ALEPH500 based on XML. This paper takes the external applications interacting with ALEPH500 of National Library as example, and introduces the using method, the functional classification, the actual application, the deployment, the details for X-server concretely, demonstrating X-server is a security, stable and convenient pattern in data transmission.

This paper surveys and analyzes the current situation of digital hardware and software in domestic libraries, and points out the shortcomings of current digital construction.The solution that depending on VMware vSphere Cloud Operation System is proposed to build virtual cloud service platform in the library.This paper introduces the functions and features of the VMware vSphere products, and based on the virtual cloud service platform of Nanjing University Library, it illustrates the application process and the practical effect.

The paper introduces the research and implementation of the centralized authentication of the library portal system, and describes the mechanism of centralized authentication as well as the workflow of SSO. Meanwhile, it also elaborates the development method of the login module of DotNetNuke, the core of the realization of the SSO.

Indexing system based on VFP and Word is a better choice to get editing indexes of multi-text Chinese ancient books. Firstly, the experiment develops the program of word segmentation to select the items of an index. Secondly, it calls the auto- marking function in Word to bring about automatic marking the items of an index and save as an index of an ancient books text. Thirdly, it uses the VFP to realize combination and integration of various indexes of ancient books. Finally, the author makes use of the function of editing and type setting in Word to achieve exporting the Pinyin, stroke and corner index of multi-text Chinese ancient books.

This paper presents a designation of sci-tech novelty searching project management based on VBA, which supports off-line working and protects the documents of sci-tech novelty searching project, and reduces the investment for software.
