Comprehenders do not wait until the end of the sentence before they build a syntactic or semantic representation for the sentence.
the challenges of successfully applying the incremental joint model to this problem formulation are: 1) how can we design an effective decoding algorithm for identifying the relations between the nodes in an incremental fashion, given a partial sequence of spans, i.e., a partial sequence of goldstandard concept fragments; 2) further, if given a sentence, how can we design an incremental framework to perform concept identification and relation identification simultaneously.
