The Legal Case Study
• In General:• Complaint about diligence of legal
administration. • Judges are overworked.
• In Particular:• New Judges • Theoretical knowledge, but few practical
knowledge• On Duty.
• When they are confronted with situations in which they are not sure what to do
• “Disturb” experienced judges with typical questions. • Usually his/her former tutor (Preparador)

Design an intelligent system to help new judges with their practical problems:
• Intelligent FAQ system using Semantic Web technologies• Connect the iFAQ system with the existing judgments
Aim of the Legal Case Study

Legal Ontologies Used
• Ontology of Professional Judicial Knowledge (OJPK)• Manual development (wiki)• 700 terms
• Topic ontologies:• Questions Topic Ontology (QTO)• Judgments Topic Ontology (JTO)• Semi automatically generated

How the System Works
• Ontology Domain Detection• Probabilistic Classification.• Detects what is the most probable domain.
• Currently the questions are classified on 35 domains.
• Question Topic Ontology (QTO)• Example 1:
He dictado una orden de protección y la mujer me pide que retire la medida. ¿La retiro?
I have given an injunction of protection and the woman is asking me for a withdrawal of the measure. Should I withdraw it?
• It is classified as “Gender Violence” with a probability of 88,42 %

I have given an injunction of protection and the woman is asking me for a withdrawal of the measure. Should I withdraw it?A lady came to the office this morning and wants an injunction of protection. It took all day. I just gave it and while I am notifying it, she now wants to withdraw the charges as she does not want the injunction of protection. What should I do?
• Keyword Match Stage• Three types of matching
• Exact Matching • Synonym Matching • Morphological Matching
• Example:

How the prototype works
• Ontology Graphs FAQ question:Ha venido por la mañana una señora que quería una orden de protección. Llevamos todo el día con el tema. Se la acabo de acordar y le estoy notificando la orden de protección y ya me dice que quiere retirar la denuncia y no quiere la orden de protección. ¿Qué hago?

From Research to Market
• Value proposition of Legal Case Study• “Understand” user queries and stored
queries• Ontology
• Calculate distance and/or similarity
• There are millions of FAQ lists
• Current exploitation efforts• eGovernment• Insurances

eGovernment: Semantic Search
• El Pais, June 2005• 91 cities > 75.000
inhabitants • Top10 is important• A reference for local
governments• Influences next year’s
priorities and budget• Three main issues
• Online services (execution): slowly improving
• WAI (legal need by 2006, level 1)
• Relation with citizens (significant underperformance)
• Aim: improve online relation with citizens

eGovernment: Cultural Heritage
• Cultural heritage of Cantabria region• Large ontology (art,
architecture, bibliographic, etc.)
• About 10 applications
• Ideal for applying SEKT technology
• Starting June 2006• Funded by “Fundacion
Marcelino Botin”

Caveat 1: Entering the Market

Caveat 2: Ontologies• The key differentiating feature of the Semantic Web are
Ontologies• They enable to distinguish it from traditional approaches• Automatic processing of unstructured information
• One of the current main obstacles for the Semantic Web is the need for Ontologies• They are hard to construct and maintain • May involve many stakeholders• Their costs are difficult to estimate and control
• Before Semantic Web technology goes to mainstream market, potential customers (businesses and governments) need to perceive that ontologies are • Doable, controllable and manageable, affordable• An asset for creating/maintaining competitive advantage• An asset that can be sold as high-value content
• Understanding and controlling cost factors of ontology engineering is critical
