The old Asian legend about the blind men and the elephant comes to mind when looking at how different authors of scientific papers describe a piece of related prior work. It turns out that different citations to the same paper often focus on different aspects of that paper and that neither provides a full description of its full set of contributions. In(More)
Multiple sequence alignment techniques have recently gained popularity in the Natural Language community, especially for tasks such as machine translation, text generation, and paraphrase identification. Prior work falls into two categories, depending on the type of input used: (a) parallel corpora (e.g., multiple translations of the same text) or (b)(More)
Multimodal conversation systems allow users to interact with computers effectively using multiple modalities, such as natural language and gesture. However, these systems have not been widely used in practical applications mainly due to their limited input understanding capability. As a result, conversation systems often fail to understand user requests and(More)
This interactive presentation describes LexNet, a graphical environment for graph-based NLP developed at the University of Michigan. LexNet includes LexRank (for text summarization), biased LexRank (for passage retrieval), and TUMBL (for binary classification). All tools in the collection are based on random walks on lexical graphs, that is graphs where(More)
We consider the problem of tracking information over time and across sources in clusters of news stories about emergency events. While previous approaches have focused on finding new information at the document and sentence levels (e.g. TDT FSD and the TREC Novelty track, respectively), we are interested in following information at the factual level.(More)
Representation of business rules in contracts has been widely studied in AI literature. Courteous Logic Programs (CLP) developed at IBM explicitly incorporates prioritized conflict handling into its declarative semantics [1][2]. Business Rules Markup Language (BRML), an XML encoding of CLP, features the representation with simple parsing, easy integration(More)
Motivation: A substantial amount of knowledge about biomolecular interactions resides in the biomedical literature and has been increasingly made available as structured, curated database entries. Although recent research in biologicalassertion extraction has mostly focused on automatically detecting interacting entities, automated generation of provenance(More)
