Extraction
Knowledge Graphs (KG) can cover
general knowledge (often also
called cross-domain or
encyclopedic knowledge), or
provide knowledge about special
domains such as biomedicine.
In most cases KGs are based on
Semantic Web standards, and have
been generated by a mixture of
automatic extraction from text or
structured data, and manual
curation work.
Examples:
▸ DBpedia
▸ Google Knowledge Graph
▸ YAGO
▸ OpenCyc
▸ Wikidata

(based on DL)
To train Google’s artificial Q&A brain, the
company uses old news stories, where
machines start to see how headlines
serve as short summaries of the longer
articles that follow. But for now, the
company still needs its team of PhD
linguists.
Spanning about 100 PhD linguists across
the globe, the Pygmalion team produces
“the gold data,” while the news stories
are the “silver.” The silver data is still
useful, because there’s so much of it. But
the gold data is essential.

a future where man and machine will collaborate to fulfill their

11 After having listened to a large
amount of music and learned its own
models of music theory, Aiva
composes its very own sheet music.
These partitions are then played by
professional artists on real

Knowledge Extraction
Semantic enhanced
Text Classification
In Semantic AI, various methods from
Symbolic AI are combined with
machine learning methods, and/or
neuronal networks.
Examples:
● Semantic enrichment of
text corpora to enhance
word embeddings
● Extraction of semantic features
from text to improve ML-based
classification tasks
● Combine ML-based with
Graph-based entity extraction
● Knowledge Graphs as a Data
Model for Machine Learning
● ….
Knowledge
Graphs as a
Data Model for
Machine Learning
These transformations can result in loss of information and introduce bias. To solve this problem, we
require machine learning methods to consume knowledge in a data model more suited to represent
this heterogeneous knowledge. We argue that knowledge graphs are that data model.
Three examples for the benefits of using knowledge graphs:
▸ they allow for true end-to-end-learning,
▸ they simplify the integration of heterogeneous data sources and data harmonization,
▸ they provide a natural way to seamlessly integrate different forms of background knowledge.
Wilcke X, Bloem P, De Boer V. The Knowledge Graph as the Default Data Model for Machine Learning. Data Science. 2017 Oct 17;1-19. Available from, DOI:
10.3233/DS-170007
13 Traditionally, when faced with
heterogeneous knowledge in a
machine learning context, data
scientists preprocess the data
and engineer feature vectors so
they can be used as input for
learning algorithms (e.g., for
classification).
POOLPARTY
SEMANTIC CLASSIFIER
Bringing Machine Learning, NLP and
Knowledge Graphs together
14
PoolParty
Semantic
Classifier
In a Nutshell
15
PoolParty Semantic Classifier combines machine learning algorithms
(SVM, Deep Learning, Naive Bayes, etc.) with Semantic Knowledge Graphs.
PoolParty
Semantic
Classifier
Feature highlights
▸ Classification
▹ Select from various machine learning
algorithms such as SVM, Deep Learning
and Naive Bayes for content classification.
▹ Benefit from a rich feature set such as
terms, concepts, shadow concepts which
gives you more flexibility when training
classifiers.
▸ User Experience
▹ A user-friendly interface enables
non-technical experts to perform
classification tasks and benefit from
machine learning.
▸ Scalability
▹ Large content repositories can be
classified on top of a Spark cluster.
▸ Easy integration
▹ New resources can be classified via the
PoolParty API.
▹ With the GraphSearch plugin system, the
Classifier can be easily integrated for
semantic applications.
▸ Transparency
▹ The Classifier works on the principles of
‘Explainable AI’.
16
Extraction,
Categorization,
Classification
What is the
difference?
▸ Classification
▹ Implemented based on a training corpus and uses the
labels of the training corpus as classes
▸ Extraction
▹ Finding terms and concepts in text, using scoring
mechanisms to give an indication of their importance
▸ Categorization
▹ Uses only concepts and categorizes text based on a
thesaurus
17
How it works
18 1. Determine classes (labels)
2. Identify training documents per class
3. Create classifier
a. Pick machine learning method
b. Choose correct parameters
c. Determine used features
d. Train model
4. Evaluate results (Cross validation/F1)
5. Goto 2. and try to find better classification
method
6. Make use of the Classifier API
Explainable AI
Classifiers based on ML algorithms such as Deep Learning perform better when training data is
semantically enhanced. Additional features are derived from a controlled vocabulary, which also
make the used features more transparent to the Data Scientist.

  • 8. Remember Knowledge Graphs & Knowledge Extraction Knowledge Graphs (KG) can cover general knowledge (often also called cross-domain or encyclopedic knowledge), or provide knowledge about special domains such as biomedicine. In most cases KGs are based on Semantic Web standards, and have been generated by a mixture of automatic extraction from text or structured data, and manual curation work. Examples: ▸ DBpedia ▸ Google Knowledge Graph ▸ YAGO ▸ OpenCyc ▸ Wikidata 8 Who is the inventor of the World Wide Web?
  • 9. The Semantic Web A standards-based graph of knowledge graphs 9 Linking Open Data cloud diagram 2017, by Andrejs Abele, John P. McCrae, Paul Buitelaar, Anja Jentzsch and Richard Cyganiak. http://lod-cloud.net/
  • 10. “Understand” Google Featured Snippets based on Sentence Compression Algorithms (based on DL) To train Google’s artificial Q&A brain, the company uses old news stories, where machines start to see how headlines serve as short summaries of the longer articles that follow. But for now, the company still needs its team of PhD linguists. Spanning about 100 PhD linguists across the globe, the Pygmalion team produces “the gold data,” while the news stories are the “silver.” The silver data is still useful, because there’s so much of it. But the gold data is essential. WIRED article 10 What is the difference between an ontology and a taxonomy?
  • 11. “Create” Example for DL-based “creativity” Aiva’s compositions still require human input with regards to orchestration and musical production. In fact, Aiva’s creators envisage a future where man and machine will collaborate to fulfill their creative potential, rather than replace one another. http://www.aiva.ai/ 11 After having listened to a large amount of music and learned its own models of music theory, Aiva composes its very own sheet music. These partitions are then played by professional artists on real instruments in a recording studio, achieving the best sound quality possible.
  • 12. What is Semantic AI? 12 Artificial Intelligence ANN Symbolic AISub-Symbolic AI Statistical AI KR & reasoning NLP Machine Learning Word Embedding Deep Learning Natural Language Understanding Entity Recognition & Linking Knowledge Extraction Semantic enhanced Text Classification In Semantic AI, various methods from Symbolic AI are combined with machine learning methods, and/or neuronal networks. Examples: ● Semantic enrichment of text corpora to enhance word embeddings ● Extraction of semantic features from text to improve ML-based classification tasks ● Combine ML-based with Graph-based entity extraction ● Knowledge Graphs as a Data Model for Machine Learning ● ….
  • 13. Knowledge Graphs as a Data Model for Machine Learning These transformations can result in loss of information and introduce bias. To solve this problem, we require machine learning methods to consume knowledge in a data model more suited to represent this heterogeneous knowledge. We argue that knowledge graphs are that data model. Three examples for the benefits of using knowledge graphs: ▸ they allow for true end-to-end-learning, ▸ they simplify the integration of heterogeneous data sources and data harmonization, ▸ they provide a natural way to seamlessly integrate different forms of background knowledge. Wilcke X, Bloem P, De Boer V. The Knowledge Graph as the Default Data Model for Machine Learning. Data Science. 2017 Oct 17;1-19. Available from, DOI: 10.3233/DS-170007 13 Traditionally, when faced with heterogeneous knowledge in a machine learning context, data scientists preprocess the data and engineer feature vectors so they can be used as input for learning algorithms (e.g., for classification).
  • 14. POOLPARTY SEMANTIC CLASSIFIER Bringing Machine Learning, NLP and Knowledge Graphs together 14
  • 15. PoolParty Semantic Classifier In a Nutshell 15 PoolParty Semantic Classifier combines machine learning algorithms (SVM, Deep Learning, Naive Bayes, etc.) with Semantic Knowledge Graphs.
  • 16. PoolParty Semantic Classifier Feature highlights ▸ Classification ▹ Select from various machine learning algorithms such as SVM, Deep Learning and Naive Bayes for content classification. ▹ Benefit from a rich feature set such as terms, concepts, shadow concepts which gives you more flexibility when training classifiers. ▸ User Experience ▹ A user-friendly interface enables non-technical experts to perform classification tasks and benefit from machine learning. ▸ Scalability ▹ Large content repositories can be classified on top of a Spark cluster. ▸ Easy integration ▹ New resources can be classified via the PoolParty API. ▹ With the GraphSearch plugin system, the Classifier can be easily integrated for semantic applications. ▸ Transparency ▹ The Classifier works on the principles of ‘Explainable AI’. 16
  • 17. Extraction, Categorization, Classification What is the difference? ▸ Classification ▹ Implemented based on a training corpus and uses the labels of the training corpus as classes ▸ Extraction ▹ Finding terms and concepts in text, using scoring mechanisms to give an indication of their importance ▸ Categorization ▹ Uses only concepts and categorizes text based on a thesaurus 17
  • 18. How it works 18 1. Determine classes (labels) 2. Identify training documents per class 3. Create classifier a. Pick machine learning method b. Choose correct parameters c. Determine used features d. Train model 4. Evaluate results (Cross validation/F1) 5. Goto 2. and try to find better classification method 6. Make use of the Classifier API
  • 19. Explainable AI Classifiers based on ML algorithms such as Deep Learning perform better when training data is semantically enhanced. Additional features are derived from a controlled vocabulary, which also make the used features more transparent to the Data Scientist. 19
