Resource bounded searches in an information marketplace

V. Lesser, B. Horling, A. Rja, Xiaoqin Zhang, T. Wagner
2000 IEEE Internet Computing  
For example, a client can instruct BIG to recommend a database package for Windows 98 and specify constraints on both the search process and the product characteristics.  ...  Over the past five years, we have been developing a Web-based, resource-bounded, information-gathering agent-called BIG, for Bounded Information Gathering-to support a human decision process.  ...  Thus far we have illustrated the DTC planner's capabilities and TAEMS using a small example. Figure 4 shows a complete TAEMS task structure generated by the task assessor.  ...
