What is structured content?

Definition:
Information that is written in reusable
blocks or components

Examples in standards:






Normative references
Terms and definitions
Scope
Table of contents
Tables
Figures
2
Benefits of using structured content


Reuse components in different contexts

Identify related information
Enrich standards metadata to facilitate
search
3
Objectives of pilot project

Extract structured content using a simple,
low-cost method

Provide an integrated framework for all
standards-related information
4
Methodology

Transform PDF documents into text files
(including scanned image files)

Parse files using custom program based
on regular expressions (patterns of strings)

Extract identified text segments

Load into database
5
Example: Normative references
-
Identify section “Normative references” in document
-
Look at beginning of line for header (e.g. IEC, CISPR, ISO)
followed by numeric reference
6
Normative references: inverse relationship

For a given standard, which other
standards use it as a normative reference

Provides an indication of the relevance of
a standard and its use by other TC/SCs

Promotes dialogue and cooperation
between TC/SCs and a systems approach

Other examples for automatic extraction

Centralized platform for standards data
Bring together all relevant information
under a single integrated interface

Conclusion

There exist simple and cost-effective ways
to extract structured information from IEC
standards (1 week effort to develop utility)

Providing standards data under a
comprehensive, integrated framework will
make it easier for end users to find and
apply relevant standards
