Conditional Random Fields for XML Trees

Abstract : We present Conditional Random Fields (XCRFs), a framework for building conditional models to label XML data. XCRFs are Conditional Random Fields over unranked trees (where every node has an unbounded number of children). The maximal cliques of the graph are triangles consisting of a node and two adjacent children. We equip XCRFs with efficient dynamic programming algorithms for inference and parameter estimation. We experiment XCRFs on tree labeling tasks for structured information extraction and schema matching. Experimental results show that labeling with XCRFs is suitable for these problems.
