Scientific workflow plays an important role in complex scientific computing. It can integrate various data and analysis functions to solve complicated geoprocessing problems which usually involve a couple of steps. They could be accomplished manually step by step in Geographic Resources Analysis Support System (GRASS), an open source Geographic Information System (GIS) software, or automated through...
We consider in this demonstration the analysis of complex data-intensive applications. We focus on three classes of analytical questions that are important for application owners and users alike: Why was a result obtained? What would be the result if the application logic or database is modified in a particular way? How can one interact with the application to achieve a particular goal? Answering...
In software project development, once implementation completes, the next phase deals with the generation of application binaries from source files. This process of generating binaries is termed as software build. Generating the binaries takes away a lot of productive time if the project is huge. However, if the generation of project binaries is performed on a distributed system, the time taken for...
Machine Translation System (MTS) that uses the Tree Adjoining Grammar (TAG) is considered. To improve the response time of our online MTS, we propose the use of a translation memory (TM). The integrated architecture of MTS with TM is outlined. Several examples of language dependent TM tools and translation process are given. To further speedup the translation process, we port MTS on a computing cluster...
This paper introduces the present development and situation of computer games, especially in connect6. Through the regulations of computer games in connect6, it is described that main technologies and principles are existing in the connnect6 game. According to the algorithm and application of other mature computer games, the five steps of connect6 method and skill is improved to be advanced and modified...
A complex analytic flow in a modern enterprise may perform multiple, logically independent, tasks where each task uses a different processing engine. We term these multi-engine flows hybrid flows. Using multiple processing engines has advantages such as rapid deployment, better performance, lower cost, and so on. However, as the number and variety of these engines grows, developing and maintaining...
Companies that provide web applications need to perform frequent regression testing because companies often encounter various security attacks and frequent feature update demands from users. Typically, such applications require regression testing processes that require minimal test effort because they have already been deployed and used in the field. In our previous work, we presented an efficient...
Interactive Voice Response (IVR) systems can handle up to 60% of the incoming calls in the call center. Since it promotes self-serving and decreases the number of the agents in the call center, it may lead to improved customer and call center agent satisfaction, increased revenue, and reduced cost. One bottleneck of IVR is that; dynamic nature of services provided by the companies and the needs of...
When the student is not able to solve a given problem, a plausible deductive reasoning process should be offered to him/her. Our final goal is a development of an e-Learning system which could help students not too much and not too little so that they can acquire as much deductive experience of independent work as possible. In the paper, we illustrate a solution plan graph which is a plausible deductive...
Recommendation System (RS) helps users (learners, educators etc.) choose quality and important content and activities in E-University Environment. This paper briefly analyses related work in application of recommendation models in E-Learning environments, enhances existing recommendation model and suggests possible usage in E-University System (EUS). Our RS is based upon main concepts of FlexRecs...
The Computer Science and Technology acting as a very applicable major in university has focused on the cultivation of students' practical abilities in the current university's education. The traditional practical direction focuses too much on programming language, database, networking and graphical calculation, however, it has ignored the workflow system which is one of the important branches of the...
Most recommendation methods are "hard-wired" into the system and support only fixed recommendations. The purpose of this demo is to show the expressivity of flexible recommendation workflows, how flexible recommendations can be processed over relational data, and to show flexible recommendations in action through a real system used for course planning.
Recently, the SPARQL query language for RDF has reached the W3C recommendation status. In response to this emerging standard, the database community is currently exploring efficient storage techniques for RDF data and evaluation strategies for SPARQL queries. A meaningful analysis and comparison of these approaches necessitates a comprehensive and universal benchmark platform. To this end, we have...
Automatic question-answer system is a very hot research in natural language processing realm. But it also exist some problems. The developing period of the Q/A system in different fields is too long, and the recycle rate is so low. To deal with it, the paper researches the generator of automatic Q/A system. First, the paper introduces the answer shape measure and the module of Q/A system. It brings...
The size of unified modeling language (UML) models used in practice is very large and ranges up to hundreds and thousands of classes. Querying of these models is used to support their quality assessment by information filtering and aggregating. For both, human cognition and automated analysis, there is a need for fast querying. In this context performance of model queries becomes an important issue...
