Cloud computing is a technology that uses the internet and central remote servers to keep up data and applications. As becomes more mature, many organizations and individuals are attracted in storing more accessible data e.g. personal data files, company related information in the cloud. This technology allows for much more efficient computing by centralizing storage, memory, processing and ban...

In the data privacy context, specifically, in statistical disclosure control techniques, microaggregation is a well-known microdata protection method, ensuring the confidentiality of each individual. In this paper, we propose a new approach of microaggregation to deal with semantic sets of categorical data, like text documents. This method relies on the WordNet framework that provides complete ...

We present the results of a small study involving the use of keyword-filler hidden Markov models (HMM) for spotting keywords in continuous speech. The performance dependence on the amount of keyword training data and the choice of model parameters is documented. Also, we demonstrate a strong correlation between individual keyword spotting performance and median duration of that keyword. This de...

The lambda and procedure-application forms in PLT Scheme support arguments that are tagged with keywords, instead of identified by position, as well as optional arguments with default values. Unlike previous keyword-argument systems for Scheme, a keyword is not self-quoting as an expression, and keyword arguments use a different calling convention than non-keyword arguments. Consequently, a key...

Many students use videos to supplement learning outside the classroom. This is particularly important for students with challenged visual capacities, for whom seeing the board during lecture is di cult. For these students, we believe that recording the lectures they attend and providing e↵ective video indexing and search tools will make it easier for them to learn course subject matter at their...

In this paper, we present a P2P-based database sharing system that provides information sharing capabilities through keyword-based search techniques. Our system requires neither a global schema nor schema mappings between different databases, and our keyword-based search algorithms are robust in the presence of frequent changes in the content and membership of peers. To facilitate data integrat...

The goal of implementing a keyword extraction system is to increase as near as 100% of precision and recall. These values are affected by the amount of extracted keywords. There are two groups of errors happened i.e. false-rejected and false-accepted keywords. To improve the performance of the system, false-rejected keywords should be recovered and the false-accepted keywords should be reduced....

Information integration has been widely addressed over the last several decades. However, it is far from solved due to the complexity of resolving schema and data heterogeneities. In this paper, we propose out attempt to alleviate such difficulty by realizing keyword search functionality for integrating information from heterogeneous databases. Our solution does not require predefined global sc...
