A Blueprint for Building Online Reference Knowledge Bases

A framework for building knowledge-bases under uncertainty

Building Knowledge-bases from the Web

The web is a vast repository of information. Most of the information on the web is meant for human consumption. Extracting structured information from the web can enable several applications like advanced ranking, semantic search, etc. In this talk, we first list different types of content available on the web, survey known techniques for extracting information from them, present the architectu...

Building Large Knowledge Bases in Molecular Biology

Large scale genome sequencing projects are now producing hugh amounts of data which can be readily stored and managed within data base management systems, and analyzed using dedicated software packages. The results of these analyzes should also be stored with the input DNA sequences. The increasing complexity and size of the objects to be described and managed have led biologists to rely on adv...

Building consensual knowledge bases: context and architecture

A protocol and architecture are presented in order to achieve consensual knowledge bases (i.e. bases in which knowledge is expressed in a formal language and which are considered as containing the state of the art in some research area). It assumes that the construction of the base must and can be achieved collectively. The architecture is based on individual workstations which provide support ...

Building Knowledge Bases from the Web

The web is a vast repository of human knowledge. Extracting structured data from web pages can enable applications like comparison shopping, and lead to improved ranking and rendering of search results. In this talk, I will describe two efforts to extract records from pages at web scale. The first is a wrapper induction system that handles end-to-end extraction tasks from clustering web pages t...
