Jiang, H; Lin, P and Qiang, M (2016) Public-opinion sentiment analysis for large hydro projects. Journal of Construction Engineering and Management, 142(2): 05015013, ISSN 0733-9364
Abstract
Public opinion is becoming increasingly involved in feasibility studies, construction, and post-evaluation of large hydro projects. Recently, with the rapid development of social network services, sentiment analysis can provide officials and managers with fresh perspectives on public-relation problems in project management. An effective sentiment analysis method can enable projects to gain from public participation. In this paper, a project sentiment analysis (PSA) system using a lexicon-based method is proposed. This system collects user opinions from social network sites, establishes emotion dictionaries, and builds basic rules that calculate those sentiment values embodied in a collection of messages. The Three Gorges project (TGP) was used as a case study for demonstrating the effectiveness of the proposed PSA. Sentiment analysis results show that about half (47.7%) of the collected messages expressed negative emotions towards the TGP, while the other messages were positive or neutral. The case study is of help to Chinese government and project managers in future decision-making regarding the TGP. The PSA system provides a new theoretical perspective and a practical method to assess public opinion during the whole life-cycle of a large hydro project.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
