It borns in response to two (2) problems:
To be able for to obtain all the parliamentary
interventions, within the legislative process
(Congress sessions and related documents)
To know the evolution and the discussion around a
law, since that this is defined as a bill until it is
published as law

To be able for to obtain all the parliamentary

(Congress sessions and related documents)
History of the Law project (HL):
To know the evolution and the discussion around a
law, since that this is defined as a bill until it is

“Sibling projects” because both are possible processing
the same documents:
• Session dailies
• Debate reports
• Reports
• Amendments
• Bills

Linked Open Data - LOD
Since 2011 BCN publishes LOD:
 Dataset of legal norms
 Dataset of legislative documents
 Datasets and ontologies about:
 People
 Geographic places
 Organizations
 Others like roles, bills, congress structure, etc.

Linked Open Data
For automatic markup we are using:
• URIs for legal documents
• URIs for metadata
• URIs for named entities:
– URIs for people
– URIs for organizations
– URIs for roles
– URIs for events
– URIs for locations
– …. URIs for all

The definition of a XML Schema
We need a XML Schema for markup of
documents, and eventually interchange the
documents, so we have two big choices:
• Own XML Schema = low interoperability,
reusability and high cost
• Standard XML Schema = high interoperability,
reusability and low cost

Named Entity Recognizer (NER)
- We need to identify entities in the text
- We are using a spanish adapted version
of Stanford NER which uses a CRF
classifier.
- The classifier was trained with large
documents achieving results over 80% of
effectivity in entity recognition

- This tool is called “The Mediator” and it has
been developed in collaboration with the

Oviedo.

Mediator features
- Connected to SPARQL Endpoint
- It allows to set context information for
each work session (ex: date, chamber,
type of doc. in markup)
- Using the context information, it applies a
set of heuristics for each entity type,
identifying correctly the URI for each one

 SOA has provided to improve each
component separately impacting positively
the final result (ex. Datasets, NER training,

 It is possible to integrate aditional XML

Conclusions
 The automatic markup of XML documents,
and subsequent manual enrichment of
metadata provides an excelent source for
data extraction
 Our solution based on SOA allow us an
easy integration of exceptions and new
cases in the markup

Alfonso Pérez, Director of the BCN, has
installed the concept of “Semantic Library” like
one of the main objectives of the BCN in the
institutional strategic plan.
This new concept implies to apply the
automatic markup schema to all BCN areas,
developing new markup schemas and possible
new challenges in terms of identify document
sections and semantic content.
