Football Transfer Market Analysis System

A simple CLIPS expert system that uses the FIFA 21 player database to give player recommendations based on user parameters.

The project uses C# and Windows Forms as GUI for the system and CLIPS for the actual processing of data.

The C# Part

The C# code is responsible for:

• Constructing the deftemplate dynamically from the database schema.
• Reading and parsing the data from the database (.csv file).
• Converting the parsed data into facts by constructing a deffacts construct and asserting all the data pulled from the database in order for the CLIPS system to make use of them.
• Validating user parameters and converting them into facts within a separate deffacts construct.
• Constructing a deftemplate for the average skill score in order to classify if a player is suitable for a certain play style.
• Read the UserSystem.clp which represents the actual CLIPS system that does the data processing.
• Combine the constructed CLIPS code with the UserSystem.clp file to create System.clp.
• Creating a batch file Clips.bat that does the (Load) on System.clp, (Reset) and (Run) then (Exit) commands via CLIPS.
• Spawning a process and passing the Clips.bat file to be executed by CLIPSDOS.exe which is the command line version of clips.
• Capturing the output from CLIPSDOS.exe, parsing it, then displaying it in a ListView.

The CLIPS Part

The CLIPS code contains a set of rules and functions that does the following:

• Process all the asserted player data by retracting all the players that don't fit the user parameters.
• Calculate the average score of each player skill for the remaining players after the initial processing done by the rules.
• Further process player data by passing them to FilterByPlayStyle function that uses the average scores of each skill to determine if a player is suitable for a certain play style.
• Lastly, the Result rule is executed to output all the remaining players that match the user parameters in a certain format that is known by the C# code in order to parse the data and display it correctly.
