    Elements of Discourse Understanding.Aravind K. Joshi, Bonnie L. Webber & Ivan A. Sag (eds.) - 1981 - Cambridge, UK: Cambridge University Press.
    The questions of how human beings produce and comprehend language continue to engage a variety of researchers and scholars, and it is becoming increasingly clear that only interdisciplinary approaches will yield productive answers. This complex issue of discourse processing is the subject of this volume, and the contributors address it from the varying perspectives of cognitive psychology linguistics, and computer science. The chapters provide a fascinating overview of emerging theories in the new discipline of cognitive science. A useful introductory chapter (...)

  2. Partial proof trees as building blocks for a categorial grammar.Aravind K. Joshi & Seth Kulick - 1997 - Linguistics and Philosophy 20 (6):637-667.
    We describe a categorial system (PPTS) based on partial proof trees(PPTs) as the building blocks of the system. The PPTs are obtained byunfolding the arguments of the type that would be associated with a lexicalitem in a simple categorial grammar. The PPTs are the basic types in thesystem and a derivation proceeds by combining PPTs together. We describe theconstruction of the finite set of basic PPTs and the operations forcombining them. PPTS can be viewed as a categorial system incorporating someof (...)

    Starting with complex primitives pays off: complicate locally, simplify globally.Aravind K. Joshi - 2004 - Cognitive Science 28 (5):637-668.
    In setting up a formal system to specify a grammar formalism, the conventional (mathematical) wisdom is to start with primitives (basic primitive structures) as simple as possible, and then introduce various operations for constructing more complex structures. An alternate approach is to start with complex (more complicated) primitives, which directly capture some crucial linguistic properties and then introduce some general operations for composing these complex structures. These two approaches provide different domains of locality, i.e., domains over which various types of (...)

    LTAG-spinal and the Treebank.Lucas Champollion & Aravind K. Joshi - unknown
    We introduce LTAG-spinal, a novel variant of traditional Lexicalized Tree Adjoining Grammar (LTAG) with desirable linguistic, computational and statistical properties. Unlike in traditional LTAG, subcategorization frames and the argument-adjunct distinction are left underspecified in LTAG-spinal. LTAG-spinal with adjunction constraints is weakly equivalent to LTAG. The LTAG-spinal formalism is used to extract an LTAG-spinal Treebank from the Penn Treebank with Propbank annotation. Based on Propbank annotation, predicate coordination and LTAG adjunction structures are successfully extracted. The LTAG-spinal Treebank makes explicit semantic relations (...)

    D-LTAG system: Discourse parsing with a lexicalized tree-adjoining grammar. [REVIEW]Katherine Forbes, Eleni Miltsakaki, Rashmi Prasad, Anoop Sarkar, Aravind Joshi & Bonnie Webber - 2003 - Journal of Logic, Language and Information 12 (3):261-279.
    We present an implementation of a discourse parsing system for alexicalized Tree-Adjoining Grammar for discourse, specifying the integrationof sentence and discourse level processing. Our system is based on theassumption that the compositional aspects of semantics at thediscourse level parallel those at the sentence level. This coupling isachieved by factoring away inferential semantics and anaphoric features ofdiscourse connectives. Computationally, this parallelism is achievedbecause both the sentence and discourse grammar are LTAG-based and the sameparser works at both levels. The approach to an (...)
