LFS: A Knowledge-Based Summarizer for Economic Statistics
The Labor Force Statistics (LFS) System, developed by
CoGenTex for Statistics Canada, automates the production
of bilingual text summaries in several areas of economic
statistics. A graphical user interface supports the display
of tabular and graphical information, from which the text

Users may set thresholds of sensitivity for analyzing trends
in the data. The output text follows the professional style
employed in published reports for each language.
Incorporates user-tunable heuristics for identifying
significant changes in statistical data over time.
Automatically plans and generates multi-paragraph
textual reports for statistical domains involving
labor force, retail trade and consumer price indices.
Coordinates the display of tables and graphs with
Uses a general language model, currently applied to
produce English and French texts, that can be extended
to additional languages on request.
