Research On Project Risk Analysis Methods Based On Text Mining

Project risk analysis plays an important role in project management. Project Risk Analysis is the uncertainty factor will affect the role of the achievement of project objectives identified, and measure the impact of the changes on elements of the project. Text data items generated during the operation of stakeholders scattered comments or various elements of the project is expected to run the state, at the same time with the development of information and communication means and lower communication costs, project stakeholders in work in the informal exchange of project-related elements of its state changes, such as a personal point of view as text displayed in all types of vehicle. Stakeholders text information in these projects represent changes in the operating conditions of the project indicates that may occur can be used to assist in project risk analysis.Studied in this paper is using of text mining techniques to identify the text data from the mass of the project risk factors and risk metrics, including design analysis method based on text mining projects and the realization of the project risk identification and analysis processes based on text mining technology work. Firstly, in order to study the project stakeholder management theory and actor-network theory in project risk management is based on a project to build a network of risk analysis, to define the scope of the project risk factors, the risk of the project into a project network nodes risk and risk caused by the network connection changes caused by changes; combining text mining constraints and project risk analysis tasks require technology, gives the text mining technology solutions can be used to identify project risks through comparative analysis. Then designed based on text mining project risk identification methods - A text mining technology framework, describes the working steps should complete the task and complete the task of inputs, processes, and outputs; and design changes in the risk of project elements measure. Finally, the actual project as a case study describes the practical implementation of the project risk analysis and risk analysis methods of risk analysis results with previous results were compared to verify the feasibility and effectiveness of the results of the risk analysis method.The proposed project risk analysis based text mining methods of risk analysis risk of changes in project work into a network structure formed by text mining to analyze, to start the analysis is not limited by project type or category of risk from the network structure to solve the use of text mining techniques can be used to analyze the limitations of a certain type of project risks. At the same time, risk-based text mining techniques to identify ways to automate the process of risk analysis, so that you can promptly identify emerging risk factors project and complete the analysis process, so that managers have more time to develop risk response plan to improve the Project emergency management capabilities.
