Increasing complexity in construction projects requires intensive research for their performance analysis. Implementation of informatics and Building Information Modelling (BIM) further affect project performance. Construction management processes can be analysed and assessed effectively through interdependence with their administrators and other users. In this literature review, we propose actors...
In order to measure the different values of a great number of knowledge spreading in virtual communities, we build a knowledge diffusion measurement model based on information entropy. The model quantifies the knowledge entropy of different nodes in the spreading process in terms of users' behaviors. Consequently, transmitted knowledge can be sorted by the knowledge entropy, making the measurement...
In recent years, we have witnessed a flourishing of location -based social networks. A well-formed representation of location knowledge is desired to cater to the need of location sensing, browsing, navigation and querying. In this paper, we aim to study the semantics of point-of-interest (POI) by exploiting the abundant heterogeneous user generated content (UGC) from different social networks. Our...
