1. EXPERT SYSTEM OVERVIEW

1.1 Problem Domain

The Queensland Police Service (QPS) has a stringent application procedure for persons who donot have any policing experience. The Police Services Administration Act 1990 (QLD) forms thebasis of the recruiting process to ensure that all applicants are fairly and equitably screened, thatdiscrimination is prevented and applicants are chosen on the basis of merit.

The selection process is conducted in three stages, all of which must be completely andthoroughly satisfied. A brief description of the stages is as follows:

Stage1: Minimum Application Requirements must be met before submitting anapplication. These include Australian or New Zealand residency, type of drivers licence,

education level and employment details, life experience, integrity and personal conduct,health, First Aid certificate and swimming proficiency.Stage 2: Only after an applicant is successful in Stage 1 are they invited to undertake Stage2 Application Testing. This stage involves an assessment to determine suitability to becomea police officer. It involves psychometric testing, health assessment, panel interview,integrity/conduct review and community/background enquiries. Again, progression throughto the next stage depends upon successful completion of all of these evaluations.Stage 3: The Selection Committee is the final stage of the police recruiting process. Thecommittee assesses the applicants who have effectively passed the previous 2 stages andmakes a recommendation to the Manager of the Human Resources Development Branch

(HRDB). The Manager then decides whether to appoint the applicant as a recruit.

Even though there are strict criteria for moving from one stage of the recruitment process to thenext, it is stated on the web site for QPS recruitment(http://www.police.qld.gov.au/join/recruitment/selectionProcess.htm ) that

"Successful completion of all or any part of the selection process does not guarantee that you will be selected or appointed as a police recruit. A limited number of positions areavailable for each recruit intake and appointments are made on the basis of merit ."

For the purpose of this report, this could be taken to mean that even though you may answerYes to a certain question, or pass a requirement, there are various levels of qualifying forsome of the conditions. For example, a candidate may do well in a physical examination, but if they are exceeded by another candidate their ranking may be reduced. Similarly with theintegrity and conduct review the scores awarded may be relative to other applicants.

Developing an expert system (ES) for this problem domain would assist the QPS committeethroughout the interview and screening processes, in all stages of assessment. The results wouldthen be used to inform their decision about whether to recommend an applicant to the HRDB.Questions in all stages of the ES would result in either a knock-out, not to continue on to the

next stage, or a continuation on to answer further questions. The results in various tests,examinations and questionnaires may be ranked and these could be translated into confidencefactors (CF) when answering the ES questions in the user interface. At the completion of theanalysis, the system will give a final confidence factor, which will be similar to a score. Thehigher confidence factors will be awarded to those applicants who meet requirements and displaypersonal traits that make them desirable recruits.

The user would enter Yes / No answers for Stage 1 questions, mostly with CFs of 100percent residency, drivers licence, First Aid certificate. Stages 2 and 3 would lend moretowards results with varying CFs, depending upon the more abstract assessments integrity,conduct, health, interviews and psychometrics. Thus, even though an applicant may extend allthe way through the 3 stages, their suitability may not be so high.

This expert system will assist in the process of screening an applicant for the process of joiningthe QPS. Its intended users are members of the committee and/or management of the HRDB and

they are not expected to have any knowledge of the mechanism of the system. A simple userinterface will be designed for use within a web site and a series of questions will be asked of theuser. A confidence level will be required with each answer, from 60% confident to 100%confident - complete certainty. The knowledge base will use pre-programmed rules to make adecision on the applicants suitability and its degree. If there is a lack of information in any areaor question, the system should deem the applicant as inconsistent with its standards the QPSrequires all conditions to be met.

1.2 Source of Expertise

The web site for the Queensland Police Service ( http://www.police.qld.gov.au/join/recruitment/ )details the entire process for an applicant to join.

In developing the knowledge base for the expert system we also contacted two people who holdvarying levels of expertise on this subject, and for the purposes of this report, are consideredexperts.

The first expert was Constable Simon Trapp who was recently accepted into the QueenslandPolice Force by undergoing the exact process that the system describes. His input was invaluable

in verifying that the stages of the procedure were accurate and in the correct order.

The second expert was Helen who is employed by the Queensland Police Service in theirrecruiting section and the questions asked of her were limited to clarifying the eliminationprocedure if an applicant did not meet all criteria. She also verified the fact that, despite allcriteria being met, all applicants are not automatically accepted and the final decision torecommend is made by the panel.

The benefits of acquiring the knowledge in this manner included:- the information was readily available and did not have to be extracted using a lengthy

interviewing process, in which it often occurs that the expert is unable to clearlyarticulate their knowledge;

- any statement from the web site that gave cause to question could be verified with ahuman expert who was involved in the process;

- the web site contained a vast and easily understood quantity of information;- the knowledge is well-stored, structured and quickly recovered if lost or forgotten.

1.3 Knowledge Engineering Process

The depth of information contained on the QPS web site was actually quite sufficient for theexpert system to be built in its initial stage. The site contains a flow chart and step-by-stepprocesses for a potential applicant to follow.

The initial stage in the knowledge engineering process was to extract the facts from theinformation in the web site. As mentioned above, the majority of the information was acquired inthis way an authoritative and endorsed web site proved to be highly informative and less proneto any error in extraction or translation from a human expert. The site contained severalimportant types of knowledge in order for the system to be developed:

- rules and procedures regarding the general problem domain; in this instance, what theexpectations were of a recruit from the Queensland Police Service;

- rules or heuristics about what should be done in a given situation; for example, whatdecision to make in the interviewing process if an applicant only narrowly passed a

particular test;

The facts were then represented as a set of IF-THEN rules in the knowledge base. These are theconditions and conclusions for all of the specific situations that the system will handle.Confidence factors were applied to each rule as we thought an expert (or panel of experts) mayapply a rating scale to an applicants criteria. An example of this would be the psychometric testwhere there is a range of results, not just a simple yes / no answer. The higher confidencefactors indicate a better result or score.

To validate the knowledge we communicated with two experts a newly successful applicant

and an employee who is involved in the actual process. The experts were given the sequencing of the system to verify that the output was accurate given various scenarios and input. Helen fromQPS was also briefly questioned to clarify some ambiguities in the final stage of the applicationprocess. Both experts agreed that the quality and logic of the system was acceptable and that thefacts were accurate.

The final expert system was developed using e2gLite , a computer application developed byexpertise2Go , who specialise in web-enabled Expert Systems. The shell enables the developer to

5

build a knowledge base within the shell, which is then accessed by the inference engine duringthe decision-making process.

In developing this system, we had to make a decision with regards to how much information wasgiven to the user at the conclusion of the systems procedure. In many cases, the inference enginewill perform a complete knock-out from the system, sometimes quite early when theapplicant has not supplied enough information or has failed a section of the process, the systemwill eliminate that applicant immediately, based on the QPS recruitment standards. In order toenable a failed applicant to determine which part was insufficient or where they neededimprovement, we developed a second expert system to continue through the process to the lastcriteria. Even in the event of an unsuccessful application, the candidate would receive outputstating all of the unsatisfied conditions as reasons for rejection.

4. EXPERT SYSTEM EVALUATION

The prototype system developed to this stage has a number of attributes that would make itbeneficial for use in the recruitment process of the Queensland Police Service.

The dual-system feature allows for better communication between would-be recruits and theselection panel. Each unsuccessful applicant could be presented with a list of reasons why theywere eliminated, which enables both a positive dismissal and a chance for improvement shouldthey wish to re-apply.

The information contained in the knowledge base enables recruiters to immediately assess anapplicants suitability given the system input. The system is portable, accurate and easy to usefor novice and expert users alike.

The problems that we foresee in the current prototype are based on any changes that would needto be made to the expert system. These changes would occur if the application process of theQueensland Police Service were to alter in some way. The existing rules would need to beadapted to accommodate a changed selection process and some would need to be re-ordered toallow for different dependencies on other criteria
