Taxonomy Of Gestures In Human Computer Interaction, Fereydoon Vafaei Jan 2013

Taxonomy Of Gestures In Human Computer Interaction, Fereydoon Vafaei

Computer Science

Classification of gestures is important in the area of gestural interaction given the diversity, the complexity and the spontaneity of the gestures in different HCI application domains. Gesture designers for interactive systems as well as state-of-the-art researchers can benefit from a well-structured classification of gestures. Moreover, a taxonomy that includes efficient classes and labels and is capable to effectively distinguish gestures can be employed as a framework to express gestures in reliable gesture recognition systems. Existing taxonomies either lack a broad scope, or are too abstract and contain ambiguous dimensions. Proposing a taxonomy of gestures, which can address the diversity …

Mining Semantic Relationships Between Concepts Across Documents Using Wikipedia Knowledge, Peng Yan Jan 2013

Mining Semantic Relationships Between Concepts Across Documents Using Wikipedia Knowledge, Peng Yan

Computer Science

The ongoing astounding growth of text data has created an enormous need for fast and efficient Text Mining algorithms. However, the sparsity and high dimensionality of text data present great challenges for representing the semantics of natural language text. Traditional approaches for document representation are mostly based on the Vector Space (VSM) Model which takes a document as an unordered collection of words and only document-level statistical information is recorded (e.g., document frequency, inverse document frequency). Due to the lack of capturing semantics in texts, for certain tasks, especially fine-grained information discovery applications, such as mining relationships between concepts, VSM …

An Application Of Association Rule Mining To Unit Test Selection, Karl Nils Gunderson Jan 2013

An Application Of Association Rule Mining To Unit Test Selection, Karl Nils Gunderson

Computer Science

Appropriate selection of unit tests during the software development process is vital when many unit tests exist. The developer may be unfamiliar with some tests and non-obvious relationships between application code and test code may exist. Poor test selection may lead to defects. This is especially true when the application is large and many developers are involved. By the application of association rule mining to the unit test selection process and by comparison with extant selection techniques, we will provide a quantitative analysis of the benefits of heuristic and its limit to development where process patterns are stable.
