This paper presents SemFrame, a system that induces frame semantic verb classes from WordNet and LDOCE. Semantic frames are thought to have significant potential in resolving the paraphrase problem challenging many language-based applications. When compared to the handcrafted FrameNet, SemFrame achieves its best recall-precision balance with 83.2% recall(More)
Fgfs direct embryogenesis of several organs, including the lung, limb, and anterior pituitary. Here we report male-to-female sex reversal in mice lacking Fibroblast growth factor 9 (Fgf9), demonstrating a novel role for FGF signaling in testicular embryogenesis. Fgf9(-/-) mice also exhibit lung hypoplasia and die at birth. Reproductive system phenotypes(More)
This paper explores factors correlating with lack of inter-annotator agreement on a word sense dis-ambiguation (WSD) task taken from SENSEVAL-2. Twenty-seven subjects were given a series of tasks requiring word sense judgments. Subjects were asked to judge the applicability of word senses to polyse-mous words used in context. Metrics of lexical ability were(More)
This paper describes automatic techniques for mapping 9611 entries in a database of English verbs to WordNet senses. The verbs were initially grouped into 491 classes based on syntactic categories. Mapping these classiied verbs into WordNet senses provides a resource that may be used for disambiguation in multilingual applications such as machine(More)
This paper focuses on an important step in the creation of a system of meaning representation and the development of semantically annotated parallel corpora, for use in applications such as machine translation, question answering, text summarization, and information retrieval. The work described below constitutes the first effort of any kind to annotate(More)
