Wrapper generation for semi-structured Internet sources

Naveen Ashish, Craig A. Knoblock
1997 SIGMOD record  
From this structure the system generates a wrapper that facilitates querying of a source and possibly integrating it with other sources.  ...  The key idea is to exploit the formatting information in pages from the source to hypothesize the underlying structure of a page.  ...  Acknowledgements We would like to thank Steve Minton and the other members of the SIMS and Ariadne projects for their contributions to this work.  ...

Personalizing Interactions with Information Systems [chapter]

Saverio Perugini, Naren Ramakrishnan
2003 Advances in Computers  
This helps bring out the role of the personalization system as a facilitator which reconciles the user's mental model with the underlying information system's organization.  ...  In this chapter, we study personalization from the viewpoint of personalizing interaction.  ...  Typically, the data to restructure is a subset of an information space and retrieved via the WHERE clause of a semistructured data query. The WHERE clause thus serves as a match operator.  ...

An Incremental Approach for Real-Time Big Data Visual Analytics

Ignacio Garcia, Ruben Casado, Abdelhamid Bouchachia
2016 2016 IEEE 4th International Conference on Future Internet of Things and Cloud Workshops (FiCloudW)  
In the age of Big Data, the real-time interactive visualization is a challenge due to latency of executing calculation over terabytes (even, petabytes) datasets.  ...  To address such a requirement, this paper introduces a new approach for real-time visualization of extremely large data-at-rest as well as data-in-motion by showing intermediate results as soon as they  ...  Acknowledgment The research leading to these results has received funding from the European Union  ...

A Survey on Visual Query Systems in the Web Era (extended version) [article]

Jorge Lloret-Gazo
2017 arXiv   pre-print
As more and more collections of data are becoming available on the web to everyone, non expert users demand easy ways to retrieve data from these collections.  ...  We have also gathered basic features of VQSs such as the visual representation adopted to present the reality of interest or the visual representation adopted to express queries.  ...  In the left part, a diagram of an XML document is shown to represent source XML documents, lets users explore the documents, and selects parts of the documents to be used in queries.  ...
