Recent research has focused on enabling the representation of, and selection from among, different opinions, while discussion among people has been ignored. This paper reports on a discussion process aimed at reconciling inconsistent perspectives in distributed workgroups. The Speech Act Theory (SAT) of Austin was extended to define both non-spatial and spatial speech acts in the context of a negotiation. A coordination process was modeled by these speech acts. Then, inconsistent perspectives were reconciled using detection of inconsistency, or initial integration of perspectives, or reconciliation of collaborators. The method we propose makes it possible to effectively describe the speech acts and use them to naturally represent the reconciliation process. A prototype system based on this approach was implemented in experiments. Their results demonstrate that a good abstraction of the negotiation process will facilitate the coordination of discussion among people and provide a criterion for system designers.

Assessment of the urban development plan of Beijing by using a CA-based urban growth model / J. Chen in Photogrammetric Engineering & Remote Sensing, PERS, vol 68 n° 10 (October 2002)

An adaptive Monte-Carlo method was used to automate the calibration of factor weights used in the CA transitional rules. We used one scene of Landsat MSS imagery from 1975 and three scenes of TM imageiy from 1984, 1991, and 1997 to classify the land-use patterns, and we used the results to calibrate the CA model. We applied the model to assess the general urban development plan entitled "disperse polycentric urban development plan" of Beijing City and found that the plan failed to meet its objectives.
