Introduction

• The framework suggests that, through legal

documents mining and criminal judgment analysis,

the new criminal behavior and its similarity with other

criminal acts can be found and the possibility of

potential criminal behavior can be foreseen..

• Unlike judicial criminal judgments, criminal cases

documents can be exploited by word mining

techniques because the judicial judgment is a legal

document. Judicial judgments can be translated into a

model by content analysis, and readers can easily read

newspapers and understand the facts, issues and ruling

Introduction

• With the help of the content analysis and the

realization of large data concepts, ordinary people

can easily employ the content analysis technology

in the semantic network to understand the complex

litigation in criminal cases and judgments.

• The purposes of this study is to construct the

Semantic Web of law information, and to render

useful reference regarding criminal issues, rulings,

and precedents (stare decisis) in different courts

and future criminal judgment trends.

Criminal cases documents analysis

• Based on the collected legal documents and the use of

natural language processing (NLP), this study uses content analysis methods to generate the concepts and relationships of relevant legal documents while extracting the subject-object (SAO) structure in criminal cases.

• NLP is a text mining technique that can conduct syntactic analysis of natural language

• NLP tools include the Stanford parser (Stanford 2013), Minipar (Lin 2003), and Knowledgist TM2.5. NLP tools will be used for building a set of SAO structures from the collected legal documents.

Criminal judgements content analysis

• The analysis of criminal cases / precedents is carried out by introducing content analysis techniques into the specified design algorithm (still in progress), searching for legal

rulings of specific keywords, and briefing them to the list of legal documents.

• Content analyses commonly contain six steps : Design Unitizing Sampling Coding Drawing inferences Validation

WordNet

• WordNet was created in the Cognitive

Science Laboratory of Princeton University

under the direction of psychology professor

George Armitage Miller starting in 1985.

PATExpert

• The European project PATExpert,

(Advanced Patent Document Processing

Techniques), coordinated by Barcelona

Media (BM), successfully accomplished the

objectives settled, after the pre-established

30 months (from February 2006 to July

Semantic Web

J. Hebeler, M. Fisher, R. Blace and A. Perez-Lopez, “Semantic Web Programming “Wiley Publishing, Inc.2009.

Constructing Semantic Web(1)

• Reasoners: Reasoners add inference to the

Semantic Web. Inference creates logical

additions that offer classification and

realization.

• The semantic web components of Rules

engines support inference typically beyond

what can be deduced from description logic.

Constructing Semantic Web(2)

• The study then turns to employ the Semantic

Web impacts functions and Semantic Web

components to increase the new data

automatically.

• The right side indicates Rules engine, the

left side represents the Reasoner.

• Over the center side is base ontology from

the modifying PATExpert ontology modules,

and under the center side is language.

Future Work

• Different Languages WordNet has ready.

• Developed to be a multi-language Semantic

Web that can use different languages to

retrieve the legal terms from different

countries and different databases.
