Publication number: 20130238607Abstract: Systems and methods for seed set expansion are provided. A context-based extractor (22) generates a set of context-based candidate members of a seed set from a set of web pages associated with an organization as words connected with a seed set member by a contextual pattern and a context confidence value for each candidate member. A list-based extractor (24) generates a set of list-based candidate members from elements within a plurality of lists in the set of web pages and a list confidence value associated with each candidate member. A confidence arbitrator (26) determines an intersection set of candidate members present in both sets of candidate members and determines a final confidence value for each of the intersection set of candidate members based on their respective context confidence value and list confidence value. A candidate selector (28) selects a candidate member for inclusion in a seed set (21).Type: ApplicationFiled: November 10, 2010Publication date: September 12, 2013Inventors: Cong-Lei Yao, Yuhong Xiong, Li-Wei Zheng
