The FRDC team participated in the IMine task of the NTCIR11, including subtopic mining and document ranking subtasks for Chinese language. In the subtopic mining subtask, we propose two methods to build the two-level hierarchy subtopics. Our methods gain high F-score and H-score respectively. In the document ranking subtask, we adopt various features for relevant webpage retrieval and document ...

| When dealing with inconsistent databases the usual approach is to repair them, i.e. take them back to a consistent state to be able to retrieve meaningful (consistent) data. This, however, has one serious drawback: it generally involves discarding inconsistent data, hence losing potentially useful information. To avoid the discarding, we present algorithm QUECA which, given a rst order query ...

-A data retrieval procedure is used to process observed dissolved oxygen (DO) concentrations in the Chesapeake Bay to obtain information on the intensity or degree of anoxia, and to explore optimal DO-thresholds to define the degree of anoxia. The method consists of a series of processes, such as data interpolation, pattern mining, feature transformation, uncertainty management, and verificatio...

purpose: libraries and information centers as information storage and retrieval systems can develop with the adoption of cybernetics rules. this paper discusses system dynamics, control, feedback, and other cybernetic concepts especially in information storage and retrieval systems. methodology: this study is a review intending to find what cybernetics and lis have in common especially in the f...

Advanced services in data compression, data storage, and data transmission have been developed and are widely used to address the required capabilities of an assortment of systems across diverse application domains. In order to reuse, integrate, unify, manage, and support heterogeneous resources, a number of works and concepts have emerged with the aim of facilitating aggregation of content and...
