We present the results of the Joint Student Response Analysis and 8th Recognizing Tex-tual Entailment Challenge, aiming to bring together researchers in educational NLP technology and textual entailment. The task of giving feedback on student answers requires semantic inference and therefore is related to recognizing textual entailment. Thus, we offered to(More)
This paper reports on a shared task involving the assignment of ICD-9-CM codes to radiology reports. Two features distinguished this task from previous shared tasks in the biomedical domain. One is that it resulted in the first freely distributable corpus of fully anonymized clinical text. This resource is permanently available and will (we hope) facilitate(More)
We describe an application of sentence alignment techniques and approximate string matching to the problem of extracting lexicographically interesting word-word pairs from multilingual corpora. Since our interest is in support systems for lexicographers rather than in fully automatic construction of lexicons, we would like to provide access to parameters(More)
This paper describes a novel approach to syntactically-informed evaluation of machine translation (MT). Using a statistical, treebank-trained parser, we extract word-word dependencies from reference translations and then compile these dependencies into a representation that allows candidate translations to be evaluated by string comparisons, as is done in(More)
The ReachOut clinical psychology shared task challenge addresses the problem of providing an automatic triage for posts to a support forum for people with a history of mental health issues. Posts are classified into green, amber, red and crisis. The non-green categories correspond to increasing levels of urgency for some form of intervention. The Thomson(More)
We describe an implementation in Carpenter's typed feature formalism, ALE, of a discourse grammar of the kind proposed by Scha, Polanyi, et al. We examine their method for resolving parallelism-dependent anaphora and show that there is a coherent feature-structural rendition of this type of grammar which uses the operations of prwrity union and(More)
