Knowledge Extraction

Team: Rachel Heaven, Simon Burden, Bob McIntosh, Ike Nkisi-Orji, Marcus Sen, Jo Walsh

Goal

Extract stratigraphic entities and observation locations from unstructured text

Intended benefits:

Interpreted map and model products can contain links to observed data points and conceptual ideas, presenting model uncertainty and provenance

Stratigraphy of an area of interest can be quickly understood from pre-existing literature, saving experts’ time

Explicit and implicit stratigraphic relations can be captured into reusable data for modelling constraints

1. XML Semantic Markup Experiments (early 2000's)

							Physiographic zones 1 and 2 cover the bulk 
							of the study area. Their character is primarily 
							controlled by bedrock type and glacial history. The 
							highly irregular middle zone (2) is underlain by 
							Permian and Triassic
							 rocks; the Permian strata include 
							Upper Permian 
							Zechstein sedimentary rocks that locally
							crop out in the study area.
						

2. Converted to training data

							highly 0
							irregular 0 
							middle 0 
							zone 0
							is 0
							underlain 0

							Permian CHRONOSTRAT
							Triassic 0
							rocks 0
							the 0
							Permian CHRONOSTRAT
							strata 0
							include 
							Upper Permian CHRONOSTRAT
							Zechstein LEXICON
							sedimentary 0
						

3. Train a custom Named Entity Recognition (NER) model for strategraphic terms

							java -cp 
							edu.stanford.nlp.ie.crf.CRFClassifier - 
							prop 
						

4. Run text mining using custom NER model for stratigraphy and core NER locations

5. Stratigraphy entities matched to BGS Linked Data Vocabs

6. Locations resolved to geometry using gazetteer

7. Database of mined data with API

9. API supports frequency and corrolation analysis

Loop Project

Involved in WP1 & WP2 knowledge extraction work

UKGEOS

A a network of observatories is being established to deliver essential new data from deep underground.

Standards

Value of geospatial is becoming more significant as the public and private sectors further embrace location

Standards play an important role in facilitating interoperability of location information and applications for improved situational awareness, business intelligence and decision making.

Standards Timeline

GIS Data

Recently included GeoPackage in data download options.

Starting to also receive GeoPackage with data requests

GIS Data

Test deployment of pygeoapi - OGCAPI-Features

More datasets coming soon - WFS > OGCAPI-Features

Sensor Data

Test deployment of FROST Server - OGC SensorThingsAPI for UKGEOS data

Again more datasets coming soon

AGS Borehole Data

Working with AGS data format committee on a AGS data validator - API & GUI

Will build generic framework based on FastAPI so can be reskinned for multiple deployents. Support for alternative versions like AGS-Australia on roadmap

Tools

Major issue of symbology tied to ESRI infrastructure

SLYR to the rescue!

BGS Data

Errors due to CRS (OSGB36) but styling is correct

Reports/Publications

Moving to Digital First - HTML

PDF publications have left us with significant legacy issues.

HTML UK Gov publishing standard

Wrap Up

BGS always interested in collaboration

In both Research & Technology
