Web information extraction [PDF]
2005 IEEE International Conference on Information Acquisition, 2006 Along with the continuous development of the Internet technologies, Web pages can provide a huge amount of information resource. It alters the traditional way of preserving and searching information. The queries target to the Web page becomes huge and more and more important.

Foundations and Trends® in Databases, 2007
The automatic extraction of information from unstructured sources has opened up new avenues for querying, organizing, and analyzing data by drawing upon the clean semantics of structured databases and the abundance of unstructured data. The field of information extraction has its genesis in the natural language processing community where the primary ...

IEEE Intelligent Systems, 2015
Information extraction constructs a structured knowledge representation from unstructured text, so that the knowledge may be further used for search, inference, and analysis. Given a specification of select types of entities, semantic relations, and events, it builds a database from instances of this information in text.

Information Extraction Framework
2012The literature provides many techniques to infer rules that can be used to configure web information extractors. Unfortunately, these techniques have been developed independently, which makes it very difficult to compare the results: there is not even a collection of datasets on which these techniques can be assessed. Furthermore, there is not a common

Informative Feature Extraction
2021Laser molecular imaging produces high-dimension data with the structure dependent on the optical modality, laser type, detection method, kind of sample, etc. Generally, data’s high dimension corresponds to a situation where the number of initial parameters exceeds by orders of magnitude the number of hidden independent variables, e.g., when the number ...

2010 5th Petascale Data Storage Workshop (PDSW '10), 2010
Designing I/O systems capable of scaling up to deal with the next generation of extreme scale scientific environments is a significant challenge. Scientific applications already strain the capabilities of current filesystems and storage systems. This work presents a middleware-based approach that generalizes from previous work on staging areas to focus
