Semantic Annotation of Animal
Accelerometry Data
 Animal-attached accelerometers
 monitor animal movement and behavior
 Tri-axial data streams




Large volumes of complex data
Lack of visualization, analysis tools and share-ability
Lack of analysis & pattern identification services
Free-ranging wild animal behavior

Lack of ground truth data


Share tri-axial accelerometer data
Visualize and analyze tri-axial accelerometer data
Share expert knowledge
Help scientists understand the movement and
behavior of animals
Use surrogates/domestic animals (& video) to train
classifier –> automatically tag rare, wild, feral animals

Evaluation

Tested on range of species (different sizes and gaits)

◦
Australian dingo (Canis lupus dingo)
Eurasian badger (Meles meles)
Bengal tiger (Panthera tigris tigris)
African cheetah (Acinonyx jubatus),
American alligator (Alligator mississippiensis)
Hairy-nosed wombat (Lasiorhinus krefftii)
Eastern Grey kangaroo (Macropus giganteus)
Short-beaked echidna (Tachyglossus aculeatus)
Running, Walking, Standing, Sitting, Lying (Sternal
recumbency)
 Test dog classification module on range of species

Results
High scores (80-90%) if SL:SH = (2-3) (Spine length: Spine height)
Benefits
Subscribers login to online service
 Leverage community expertise to tag training sets
 Develop libraries of classifiers for different species
 Apply domestic species classifiers to wild species

Dogs ->dingos, foxes; birds->bats; horses->camels

Classifiers – improve over time as more data uploaded
Socio-economic and health benefits:
◦ livestock productivity – assess health, energy/food needs
◦ reduce spread of feral pests & viruses
◦ management & conservation of threatened species

125 sensor nodes :
• Air temperature
• Humidity
• Wind Speed
• Leaf Wetness
CSIRO Sensor Network
Semantic Fire Weather Index
Calculate FWI from: wind speed, relative
humidity, temperature
Limitations:
- Widely distributed sensors (tens of km apart)
- Updated once per day
- Urgent need for data with higher spatiotemporal resolution

System Architecture
Combine SPARQL inference rules with an Inverse Distance Weighting
to calculate accurate spatial distributions

Reasoning across Knowledge Base
• Analyze Diagnoses, Phenotypes, Genotypes
- Across Patients and Publications
• Extract/infer new relationships
- Disease <-> phenotypes <-> genotypes
- Capture provenance, certainty, temporality, severity,
polarity
Aboriginal Housing Crisis
Aboriginal communities:
 Inferior housing
 Inferior neighbourhoods
 Low home ownership
 More live in public housing
 Greater overcrowding, homelessness
 Move house more frequently
-> Adverse impact on health, well-being and education

Inaccurate data
Anonymized data – post-code level of geography
What are the optimum data sources/indicators
for successful housing programs?
For a given region, what are the most significant
factors that need to be considered, to satisfy the
housing needs of the local Indigenous community?
What are the optimum governance structures
that combine
◦ economies of scale
◦ localized approaches informed by Aboriginal
Community Councils?
