ABSTRACT
Expertise recommendation is a peculiar task in recommender systems development because it deals with humans who possess the attribute of reason, as items for recommendation compared to other items such as movies, songs, books, among others. Previous systems have deployed feedback through rating of experts by users as a means of evaluating their expertise in order to enhance quality of recommendation. However, this method is deficient because it denies the experts the opportunity of airing their opinion about the activity for which they were being rated by the users, especially in academic research. This has made the feedback mechanism in existing systems a one-way structure. To address this challenge, a bidirectional feedback approach to expertise recommendation in academic research that incorporates user classification is therefore proposed. The proposed system was developed using Unified Modeling Language (UML) for the model design, MySql for the database implementation, Java Script and Hypertext-Pre-Processor (PHP) for the program coding. The proposed system was evaluated using precision and recall. It was further benchmarked using the harmonic mean difference between the expertise recommendation approach of an existing system and the proposed system. The results from both systems were shown using line charts. The benchmarking result indicated that the proposed system outperformed the existing system by 2.5%.
