an innovative linked open data search engine


The project have a duration of 24 months and it started in January 2013.

The project's primary objective is to build a prototype of an
innovative data search engine.

The aim of our data search engine is to make easier to find and to use the information published online by various institutions.
Il Progetto ODINet è realizzato con il determinante contributo della Regione Toscana a valere sul
Programma Operativo Regionale cofinanziato dal FESR per l’obiettivo “Competitività regionale e

Harvested data are analyzed to extract:
spatial coverage
(administrative boundaries,
coordinates, polygonal areas, etc.)
temporal coverage
(months, years, etc.)
concepts
(SKOS): what the data talk about?
data structure
(RDF Data Cube Vocabulary)
mapping metadata
in DCAT and ORG


Data Enrichment
Specialized Ontologies
Data Harvesting
CKAN API
SOCRATA OPEN DATA API (SODA)
STATPORTAL OPEN DATA
SDMX

Economic web portal
Social web portal
Linked
Open Data
When it's possibile data are linked together:
(es. SPC, GeoNames,ecc.)
...and so they become
Linked Open Data
!

Data and ontologies are also linked together,
generating a graph whose entities (nodes) are:
data
concepts (skos:concept)
themes (dcat:themeTaxonomy)
keywords (dcat:keyword)

Data Linkage
Social Network Analysis
Search result ranking is calculated
applying SNA tecnique like:
