OMFM: A Framework of Object Merging Based on Fuzzy Multisets

Abstract EN

Information fusion is a process of merging information from multiple sources into a new set of information.

Existing work on information fusion is applicable in various scenarios such as multiagent system, group decision making, and multidocument summarization.

This paper intends to develop an effective framework to solve object merging problem based on fuzzy multisets.

The objects defined in this paper are data segments in document fusion task, referring to the concepts with semantic-related terms of different semantic relations embedded.

The fundamental operation is the merge function mapping data segments in multiple fuzzy multisets onto one object, which is a solution.

Under this framework, we define quality measures of purity and entropy to quantify the quality of the solutions, balancing accurateness, and completeness of the results.

Merge function that yields this kind of solutions is VI-optimal merge function and a series of theoretical properties concerning it are studied.

Finally, we investigate the proposed framework in a special application scenario (i.e., document fusion) which is related to the task of multidocument summarization and show how the framework works with illustrative example.
