| Abstract | This research aimed to extract road traffic accident reports and perform usability testing of the presented relevant information. The process started from collecting data on large-scale accidents from websites, pre-processing the data for text analysis and handling typographical errors by measuring text similarity using the Levenshtein distance for creating a specialized corpus and entity extraction to extract relevant information in 6 issues, namely, province, date, number of deaths, number of injuries, type and number of motor vehicle(s) involved in the accidents. The information was then visually presented to the web user via data visualization. When evaluating the information retrieval by three indicators, i.e., Precision, Recall, and F-measure, the average accuracy of information retrieval for the tested samples were 0.87, 0.85, and 0.86, respectively. The result on usability testing of the presented information, based on 30 users selected by non-probability sampling via the purposive sampling method, was at a good level (xˉ = 3.73). Prior to the analysis of the data, the assumptions of linear regression were checked. When analyzing multiple regression with stepwise selection procedures, 6 variables were noted to be involved: the accuracy of the extracted road traffic accident reports, the ability to rapidly use the system, the accuracy of the presented results as per the search criteria, the ability of understand the process of obtaining results on one’s own, the accuracy of the placement of the list of provinces for searching and the speed at which the data are presented. All variables exhibited the prediction accuracy of the overall information presentation capability of 87.2, with multiple coefficients value of .934, which was significant. The user performance components tended to be in the same direction, while the user opinions components varied with the relevant context. |
