Project NAZOU

  • NAZOU - Tools for Knowledge Discovery, Maintenance and Presentation

  • Goals and Challenges:

    • Acquire information from public sources

    • Discover knowledge

    • Make knowledge available in computer processable form

    • In the form of Ontologies (enable automatic reasoning)

  • For specific domains only!

    • Jobs offers

Tools Chain


ISIM’06, Přerov 26.4.06; Corporate Memory

Corporate Memory in NAZOU

  • Integration of tools at the data layer

  • Virtualization of data resources

  • Uniform way to access the data

  • Uniform access even in the case of change of physical data resources architecture

  • Provide access to different kinds of data resources

    • Plain text files

    • Relational db

    • Ontological data

Manipulation Layer


ISIM’06, Přerov 26.4.06; Corporate Memory

Physical Layer

  • Files repository

    • vfat, ext3

  • RDBM

    • MySql

  • Ontological storage

    • Jena

    • Sesame

ONTO Client

  • Needs:

    • Common formalized version of offers

    • Reasoning, inference

    • Common offers presentation

  • Operations (example)

    • Insert() – inserts OWL models in XML/RDF format into Onto CM

    • getXML() – returns plain XML of resource from Onto CM

    • executeRDQLQuery()- returns RDF ID result list for given RDQL query


ISIM’06, Přerov 26.4.06; Corporate Memory

Files Client

  • Needs:

    • Access to acquired original data files

    • Access plaintext form of original data

    • Store textual output of tools

  • Operations (example):

    • insert files to CM (as data stream / from uri)

    • deliver file (as stream / request URI)

    • list, cp, mv, delete


ISIM’06, Přerov 26.4.06; Corporate Memory

db client

  • Needs:

    • Store indices of content of documents and offers

    • Provide fast full-text search

    • Provide functionality for textual mining tools

  • Operations:

    • execute sql queries

    • enable definition of query templates

    • execution of stored procedures

    • update/insert/delete statements and templates


ISIM’06, Přerov 26.4.06; Corporate Memory

Conclusions

Corporate Memory

  • Utility for integration of tools at the data layer

  • Virtualization of data resources

  • Uniform way to access the data

  • Provide access to different kinds of data resources

    • Plain text files

    • Relational db

    • Ontologies
