Usually, most of execution time of match-resolve-act reasoning cycle is spent in the matching phase. This issue has prevented the applicability of rule base systems. In this paper, the parallelism of alpha- and beta-networks constructions in rete algorithm have been realized on Graphics Processing Unit (GPU). It is possible to speed up the reasoning time 20 times faster than the current high performance multi-core processors. Furthermore, the parallel realization of rete algorithm with GPU should be helpful on developing intelligent agents or data mining, using rule base systems.

The rete algorithm is an efficiently organized pattern matching algorithm for implementing production rule systems, used to determine which of the production rules should fire based on its data store. This paper presents how rete algorithm can be used to improve the efficiency of expert system recommendation. The 'COURSE FINDER' is an expert undergraduate course recommendation system. This system aims to assist undergraduate students who wish to join Amrita School of Arts and Sciences, Mysore. This expert system enables students to select suitable courses based on their skill sets without needing to consult an advisor. This system works on Rule based mechanism and rete algorithm. The result was expected, where most of the undergraduate students who tested the system, were satisfied.

Environment state estimation and control action determination is the key step in industrial environment control. In some complex environments, decisive factors may be various, and each has multiple thresholds, a large number of matching operations have to be done by the controller, and it is a problem to do all rule judgments quickly and precisely. First, the problem is analyzed and main steps and characteristics of rete network for estimation of multiple factors are given. Second, the improvement of conventional rete algorithm, beforehand matching, is analyzed, and then, according to the properties of industrial environments, branch filtration, is introduced based on beforehand matching as a new improvement of rete algorithm. Finally some tests are carried out, and by comparing with conventional rete algorithm and the algorithm with beforehand matching, it can be seen that the improved rete algorithm with branch filtration is effective in reducing unnecessary matching operations.

In this paper, we propose a control method of ubiquitous computers using the rete algorithm in grid topology network. The proposed method distributes and reduces the loads for processing rules and collecting data based on the rete algorithm. We evaluated the proposed method and confirmed that the proposed method reduces the network traffic as loads.

The study is a mobile health(M-Health) expert system embedded on Android OS phones as an assistance tool that can support people experiencing physical injuries. It utilizes the rete algorithm which is present on most expert systems. The system covers physical injuries which commonly experienced by athletes and students enrolled in human kinetics. Physical injuries are categorized into head, upper body and lower body parts. From these parts, they are defined by type such as: skin injury, bone injury, muscle injury and body pains. The researchers used descriptive method in the study. After the system was developed, it was evaluated by the two groups of respondents: a) experts and b) students based on the four(4) parameters such as user-friendliness, functionality, usability and appropriateness of advice. According to the data gathered, analyzed and computed, the proponents found out that there is no significant difference between the evaluation made by the students and by the experts on the developed mobile health application. Both groups of respondents recommend the implementation of CERES.

The rete algorithm is a well-known pattern matching algorithm conceived to make rule-based production system implementations more efficient. It builds a directed acyclic graph, representing higher-level rule sets, that allows the implementation to avoid checking each step the applicability of all the rules. Instead, only those affected by a change in the collection of facts are checked. In this paper we study how the underlying ideas of this algorithm can be adapted to improve the design of computational simulators within the framework of Membrane Computing.
