The mechanics of the presentation mining framework

This paper presents the mechanics of a presentation mining system that mines keywords and key phrases from a collection of powerpoint slides and generates a mind map using the extracted words and phrases. the core of presentation mining lies in two stages; ranking the potential phrases and extracting the keywords and key phrases. the keywords and key phrases form a mind map,which is then evaluated against a domain ontology. the results of recall and precision are also compared between the existing key phrase extraction system called the kp-miner and the proposed presentation mining system. the key phrase extraction algorithm by the proposed presentation mining system achieved higher recall and precision than kp-miner,hence producing a more accurate visualization of the powerpoint slides in the form of mind map. © 2016 penerbit utm press. all rights reserved.
