In order to satisfy the strong demands of learning paper-cut from the public and paper-cut lovers and the needs of art education and training to practical ability for children and teenagers.Taking full use of the advantages and features of 2D interactive animation, we designed and implemented a virtual interactive system based on the classification of paper-cutting technique. Learners without paper-cutting experience can master the basic techniques of paper-cutting, and appreciate the integrity of the production process of paper-cutting through this system, which will promote the inheritance and development of folk paper-cut product techniques.

Most of the scientific research engines utilize the same way to rank scientific research papers (SRP), this way is highly depend on the citation network. The retrieved results of these engines for any keyword contain old papers with the highest citation value. In this paper, we proposed a new and easy to implement ranking algorithm for scientific research papers known as Paper Time Ranking Algorithm (PTRA). PTRA is a new ranking algorithm that depends on three factors to rank its results; paper age, citation index and publication venue. To construct and prove our ranking algorithm we created a web crawler that crawl different scientific search papers databases in the world to collect the information that PTRA needs. Unfortunately, some of this information was missing, such as, the impact factor of the journals. To collect this information, we created another crawler that search the Internet for these journals impact factors. However, to prove our ranking algorithm results, we have compared PTRA with Google scholar ranking algorithm. We used Google scholar, since it has more than 50 million papers and its own system can gather and collect papers in a faster way. Our comparison results show that, citation index has the highest impact on Google scholars ranking algorithm results. Unlike PTRA that gains the paper age a higher impact on the ranked results. However, PTRA depends on the citation index and publication venue to rank the results but with less impact than the paper age.

The contribution deals with the possibilities of the use of existing commercially available vectorization programs for recognition drawing entities in raster graphics format obtained by scanning of the engineering drawing. Drawing entities as a line (solid, dashed, dot-dashed etc.), dimension, hatch, various symbols, text, etc., have specific semantic for the designer defined by standards. Expert knows to interpret this graphic language and he knows to create a mental model of the real object. To be able interpret digital content of the engineering drawing obtained by scanning by the form of 3D computer model often requires to perform many intelligent operations. In the first step it is necessary to obtain such vector representation of the scanned drawing to be able to identify the original drawing entities. Suitability of using the contemporary commercial vectorizing programs for engineering drawings was verified on the test sample of the drawing entities and the results are published in the paper.

This paper proposes a storage-independent model for SPARQL-to-SQL translation algorithm based on relational view. During the development of Web ontology researches, the study for translation from SPARQL to SQL still remain issue. Previous researches focus on efficient and complete translation from SPARQL queries into equivalent SQL queries. However, these translation algorithms depend on specific structure of storages. When we modify the structure of storage, the translation algorithm also should be modified suitable changed structure of storage. This motivates us to study the issue of a model for independent use upon storage structures of an algorithm, which can then be guaranteed independency between translation algorithms and storages by generating relational view, and it improves application and usability of a translation algorithm. In addition, this paper show experiment result about accuracy and no data loss rate of query results on several storages.

The query of database must rely on professional query language, which is difficult to grasp for ordinary users. Natural language query interface (NLQI) can be applied to solve this problem with better human-computer interaction and intelligence. However, current natural language understanding technology is not mature. Though the query sentences’ structure is fixed, it is also difficult to accurately convert query sentences into understandable database query language for computer. Therefore a method of designing NLQI based on syntax and semantic analysis is proposed in this paper. First of all, Maximum forward and maximum reverse matching algorithms are used to analyse sentence by part of speech (POS) template, which is able to demonstrate the syntax relationship among the words. After syntax analysis, query conditions and targets are identified. Then, single conditions and targets are analyzed to relative standard forms by the relationship among entity, property, connect verb and unit. At last, these standard forms are transformed to SQL sentence. Regarding printing ERP system as experimental subject, experiment is done in this paper. The result shows that the method proposed in this paper can meet the needs of natural language query, and has a good transform effect for combination, omitting and other complex sentences.
