Exploring Knowledge Learning in Collaborative Information Seeking Process

Yu Chi, Shuguang Han, Daqing He, Rui Meng
2016 Annual International ACM SIGIR Conference on Research and Development in Information Retrieval  
However, there still lacks a fine-grained understanding of users' knowledge change patterns within a search process and users' adoption of different sources for learning.  ...  Knowledge learning is recognized as an important component in people's search process. Existing studies on this topic usually measure the knowledge growth before and after a search.  ...  Several other studies [3, 15] regarded users' knowledge as a function of users' search behaviors and thus the knowledge change can be implicitly reflected by the changes of users' search behaviors.  ...

Schema evolution for object-based accounting database systems [chapter]

Jia -Lin Chen, Dennis McLeod, Daniel O'Leary
1994 Lecture Notes in Computer Science  
Second, we explore how domain-specific knowledge can be used to guide the use of evolution operators to complete the evolution task.  ...  This research proceeds in the following three steps. First, we define a set of basic evolution schema operators and employ the evolution heuristics to guide the evolution process.  ...  However, their research did not employ heuristics or domain knowledge to guide an end-user in completing evolution tasks.  ...
