Slides for lecture 3 of the course Introduction to Legal Technology at the University of Turku Law School, presented Jan 27 2015.
This lecture presents a number of modern AI technologies which in my opinion are indicative of the direction legal AI is likely to take over the coming decade or two.

2. Overall claim: Law is ~20 years behind
other fields in intelligent tech adoption
- nearby point of reference: language
technology
- things originally considered AI don’t seem
all that impressive anymore (only annoying
when not functioning properly):
- spelling and grammar checking
- speech recognition and generation
- machine translation
- ...
3. Why?
- lawyers are conservative (but that’s too easy
an explanation)
- lack of practically relevant research?
- lack of commercial incentives
- jurisdictional etc fragmentation means the
incentives are even smaller (but it’s the same
for languages)
- law is HARD (but then you should just start
with the low-hanging fruits)
5. What I worked on through much of
law school...
AnswerWizard/IntelliSearch, an intelligent tool
for providing answers from on-line help files to
questions posed in natural language,
introduced in Microsoft Office 95:
6. But the next version (Office 97) might
be more recognizable...
7. But the next version (Office 97–) might
be more recognizable...
8. The basic tech was originally developed at
the Stanford Research Institute (SRI)...
... and 10 years later, the same project gave us

15. Putting it all together: From raw
materials to Getting Things Done™
- Semantic Finlex: legislation as linked open
data
- self-organized law systematics
- recommender engine for law
- INDIGO: intelligent backoffice processing for
public administration
...and plenty others (a task-based overview
coming up at lectures 5–7)
16. Semantic Finlex
- project carried out at Aalto U by Frosterus,
Tuominen, Hyvönen, funded by Tekes
- Finnish legislation and case law as linked
open data
- uses an ontology for legal source metadata
(which can be used to link them)
- http://www.ldf.fi/dataset/finlex
19. Pros and cons
- these kinds of resources are mandatory as
building blocks for more advanced things
- it is available for Free™
- semantic enhancement only covers metadata
(not legal concepts, yet anyway)
- based on 2012 legislation, no updates
- only discovers explicit references
20. Systematizing Estonian laws through
self-organization
- project carried out at Tallinn U of Tech by
Täks et al
- legal acts modelled as term vectors (based
on occurrences of individual words in each
document) which are used to generate a
self-organizing map (SOM, Kohonen)
- provides a 2-dimensional map of
hypothetical (and also actual) relationships
between statutes
23. Recommender engine for legal sources
- project carried out at the Leibniz Centre at U of
Amsterdam by Winkels et al
- uses networks of references (legislation ->
legislation, case law -> legislation) to find all
documents matching the current document
within a given horizon
- uses network topology based metrics to find
the best matches (but plenty of other metrics to
choose from)
- currently only prototype; in production could
also learn from behavioural data (just like your
favourite online store!)
24. Intelligent case management platform:
INDiGO
- project carried out for the Dutch
Immigration and Naturalization Service
(IND) by Ordina, Accenture, Be Informed
- replaced an earlier paper-based
administrative procedure
- intelligent decision support based on
decision trees and checklists
- rules modelled in the system using a
proprietary language
25. Semantic models in INDiGO
- core taxonomies
- regulations
- online front office (UI)
- catalog (index)
