INTRODUCTION
INTRODUCTION
Our team worked on a predefined problem (the problem statement #3) – “Visualizing the Case Network”. The purpose of this project was to develop a visual system that could represent the citation linkages between legal cases.
USER NEEDS
USER NEEDS
This project kicked off with some general user needs within the task statement. We talked with on-site mentors and legal practitioners to clarify users’ needs in more detail.
Typical Users
Attorneys and researchers (who do research on legal cases).
Characteristics
Their schedule is tight;
They need quick access to the most important and relevant cases;
They need to be able to find seminal precedents while putting cases together;
They need to be able to easily navigate to cite related cases and topics.
THE QUEST
THE QUEST
SEMI-STRUCTURED INTERVIEW
SEMI-STRUCTURED INTERVIEW
Our group worked out an interview protocol for the purpose of exploring how users approach the system, their expectations, and their concerns.
Within a limited time, we did a telephone interview with an attorney and found out:
It is fundamental to define “the state of the art” on the subject that the user is exploring.
How to search the legal cases quickly and efficiently are the top two concerns; Need to make sure that users can easily find strong cases.
There are generally two types of users – the “explorers” and the “focused users”.
PERSONAS
PERSONAS
From the interview, we synthesized two major user personas - the “explorers” and the “focused users”.
USER JOURNEY
USER JOURNEY
To further understand the user’s journey when they interact with the system, our team did a user journey map with pain points analysis. This diagram helped us to find out touchpoints, as well as possible pain points throughout the user’s interaction with the system. We also wanted to see how users in different phases of the journey would have different goals to accomplish.
Pain Points
The current interface is textual and not have any way of visualizing the case network;
Hard to find related cases in a big picture;
Hard to find the importance of each case in each topic area.
OUR SOLUTION (1.0 DEMO)
OUR SOLUTION (1.0 DEMO)
We developed a new way to search and visualize the case network that emphasizes the most important precedents and allows the user to see the connections between cases.
Magic Search
Magic Search
The first interaction between users and the database is the Magic Search box. The user feels welcome and familiar with the search format. (Type keywords & suggestions pop up)
Refine & Explore
Refine & Explore
The user can refine the searching by adding/deleting keywords. Users can also input jurisdiction, practice area, case status, date, and minimum number and citations.
The visualization itself is structured primarily around keywords and inbound citations, giving the most important to the seminal precedents in each topic area. The circle size corresponds with the number of citations each case has, and the lines represent connections to newer cases that have cited the original. This filtering system gives attorneys quick access to the most important cases in the field and allows them to see connections between cases, both large and small.
The color of the circles represents Shepard’s category that is already in use in Lexis Advance to provide a report of the cases that cite your authority, including more recent cases that rely on the user’s starting case. This report can be used to quickly validate the user's’ research and ensure they have good law.
Interactive Results
Interactive Results
The user can interact with the cases represented in the visualization by hovering over the circles, and a preview pops up of each case with title, keywords, and dates. If the user clicks on the case, the visualization zooms into that case, and the results on the right update with the new selection.
Organize & Print
Organize & Print
In the final stage of the user journey, the user can easily bookmark, download, and print the articles they will use for their case.
CONCLUSION
CONCLUSION
This innovative solution allows users to visualize the case network, save time, and access the cases that are most important to them. This continues their commitment to the rule of law, many cases at a time.
