Xponents 3.5 "Begin Again"

Happy New Year

Xponents 3.5.4 BeginAgain

• Full Evaluation: internal evaluation work was redone start to finish to hone outlier gazetteer entries and
  patterns of rogue entries from new data sources. Evaluation work called out and fixed serious false-positive and recall
  errors
• Log4J Remediation: While Log4J is not the primary choice of logging facility, it is a dependency that appears
  mainly in the Solr 7.x server distribution. Vulnerable Log4J JAR files were removed and latest ones were injected.
• API Changes:
  • TextEntity is a text span and requires a start, end offset pair. Only constructor
    requires that pair. Other subclasses can have a zero argument constructor by exception, such as PoLiMatch
  • GeonamesUtility.isCountry() now only returns true for PCLI entries others are historical country names or territories.
  • REST API now has method and match-id on most matches to be more consistent

TESTING:

Deploy: https://github.com/OpenSextant/Xponents/blob/master/Examples/Docker/docker-compose.yml

Install client library

pip3 install opensextant-1.4.5.tar.gz

Use Test suite: https://github.com/OpenSextant/Xponents/blob/master/test/xlayer-test-suite.py

DEFAULT_URL=localhost:8787
python3 xlayer-test-suite.py   $DEFAULT_URL

Test output:

• Consult docker logs on docker container, ala docker logs xponents to see that server is alive
• Review output to console -- unit tests results for normal geotagging, postal geotagging and tests in Arabic and Japanese should appear.
