Rhetorical based Music-Inspired Optimization Algorithm: Harmony-TABU for Document Retrieval using Relevance Feedback Approach
نویسندگان
چکیده
Harmony search (HS) is a meta-heuristic algorithm mimicking the improvisation process of musicians. This paper arranges the basic structure of the HS algorithm and customizes the algorithm for clustering optimization problems. We propose novel clustering algorithm based on Harmony Search (HS) optimization method that deals with document clustering. By modeling Retrieval as an optimization problem, first, we propose a pure HS based clustering algorithm, then we hybridize Harmony clustering with TABU to achieve better retrieval. Experimental results reveal that the proposed algorithms can find better results when compared to HS and TABU methods and the quality of results is comparable. Then Relevance feedback mechanisms such as term feedback, cluster feedback and term-cluster feedback are used to further improve the retrieved results. Finally we propose abstract generation system based on rhetorical structure for generating abstract for the retrieved documents.

متن کاملMultiresponse surface optimization via Harmony search algorithm (Quality Engineering Conference Paper)
Response surface methodology is a common tool in optimizing processes. It mainly concerns situations when there is only one response of interest. However, many designed experiments often involve simultaneous optimization of several quality characteristics. This is called a Multiresponse Surface Optimization problem. A common approach in dealing with these problems is to apply desirability funct...

متن کاملRobust Design of Power System Stabilizer using Harmony Search Algorithm
In this paper, a novel Harmony Search algorithm (HSA) based approach for robust and optimal design of PID controller connected to power system stabilizer (PSS) is proposed for damping low frequency power oscillations of a single machine infinite bus bar (SMIB) power system. This paper attempts to optimize the three parameters (Kp, Ki, Kd) of PID-PSS via a music-based metaheuristic optimization ...
متن کاملTabu-KM: A Hybrid Clustering Algorithm Based on Tabu Search Approach
The clustering problem under the criterion of minimum sum of squares is a non-convex and non-linear program, which possesses many locally optimal values, resulting that its solution often falls into these trap and therefore cannot converge to global optima solution. In this paper, an efficient hybrid optimization algorithm is developed for solving this problem, called Tabu-KM. It gathers the ...
