In previous studies, no consensus has been reached on the existence of significant correlation between perception and production. A large number of empirical studies have been done upon first and second languages from different language families. However, few studies were carried out on the perception-production relation of Chinese English learners. Therefore, in the current study, under the theoretical...
This paper addresses conformance testing of communication protocols. The Session Initiation Protocol (SIP) is often considered "the standard protocol" for deploying VoIP (Voice over IP) solutions. We implemented a popular SIP distributed scenario on an industrial test bed. Active testing of SIP maintains our attention, while we kept on experimenting with the test cases dependencies architecture...
Unlike physical services, e-services lack human interaction, which calls for them to be designed in a more human-like way. From the conventional marketing perspective, the concept of brand personality is used to explain the human characteristics associated with a brand. Regrettably, existing brand personality dimensions are context-specific and are often developed using physical products and services...
Due to changes in the development practices at Axis Communications, towards continuous integration, faster regression testing feedback is needed. The current automated regression test suite takes approximately seven hours to run which prevents developers from integrating code changes several times a day as preferred. Therefore we want to implement a highly selective yet accurate regression testing...
Software quality is one of the most pressing concerns for nearly all software developing companies. At the same time, software companies also seek to shorten their release cycles to meet market demands while maintaining their product quality. Identifying problematic code areas becomes more and more important. Defect prediction models became popular in recent years and many different code and process...
Word sense induction (WSI) is the problem of automatic identification of word senses given the corpus. This paper presents a method for solving WSI problem based on the context clustering approach. The idea behind this approach is that similar contexts indicate similar meanings. Specifically, we have successfully applied Correlated Topic Model (CTM) to partition contexts of a word into clusters, each...
This paper presents empirical studies of test effectiveness for Java database applications. We primarily address two research questions: (1) What is the relationship between test set size, coverage criteria, and test effectiveness for Java/JDBC programs? (2) Which adequacy criterion is more suitable for testing Java database applications, statement coverage, branch coverage, or command form coverage?...
Recently, concept correlation defining the relationship between concepts has been playing an important role in video annotation (or concept detection). To improve the annotation performance, this paper presents a two-view concept correlation based video annotation refinement, using data-specific spatial and temporal concept correlations. Specifically, instead of generic concept correlation within...
Web services are the element based in SOA (i.e., Service Oriented Architecture) applications that are commonly used in software systems. However the validation problem on quality of web services via testing has to be improved. This paper presents two tools for conformance testing of web services. One tool for unit testing that is implemented by an on-line approach. This tool can be used to test a...
The advent of the Deep Submicron technology opens the way to many-cores processor chips. However, the variability and reliability of these processes poses new challenges. In particular, the mapping of applications will require specific strategies to leverage the plenty and diversity of the computation cores. In this work, a high-level study of the variability impact on Thousands-core processors is...
We build a Student-Partner mobile English learning system. We go deep into the campus to do English learning by portable of the mobile. The system offer the GPS function, campus map, camera, messaging, tracking and recording. Students can post the message or add the multimedia which he explore to the device. In the mobile, user can off-line to post the message. In addition, we design two activities,...
Correlation of anxiety and motivation was studied by means of questionnaire. The results show that inner interest motivation and effort intensity are significantly and negatively correlated with anxiety while achievement motivation. Learning context motivation is significantly and positively correlated with anxiety. Pedagogic implications are given according to the findings of study, like developing...
Test coverage is a promising measure of test effectiveness and development organizations are interested in cost-effective levels of coverage that provide sufficient fault removal with contained testing effort. We have conducted a multiple-case study on two dissimilar industrial software projects to investigate if test coverage reflects test effectiveness and to find the relationship between test effort...
