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

Enrich standards metadata to facilitate search

Identify related information

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

7

Other examples for automatic extraction

8

Centralized platform for standards data

Bring together all relevant information under a single integrated interface

Normative references

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
