    • Acceptance of Mobile Technology by Older Adults: A Preliminary Study 

      Kim, Sunyoung; Gajos, Krzysztof Z; Muller, Michael; Grosz, Barbara J. (2016)
      Mobile technologies offer the potential for enhanced healthcare, especially by supporting self-management of chronic care. For these technologies to impact chronic care, they need to work for older adults, because the ...
    • Agent Decision-Making in Open Mixed Networks 

      Gal, Ya'akov; Grosz, Barbara J.; Kraus, Sarit; Shieber, Stuart M. (Elsevier, 2010)
      Computer systems increasingly carry out tasks in mixed networks, that is in group settings in which they interact both with other computer systems and with people. Participants in these heterogeneous human-computer groups ...
    • AI Support of Teamwork for Coordinated Care of Children with Complex Conditions 

      Amir, Ofra; Grosz, Barbara J.; Gajos, Krzysztof Z; Swenson, Sonja M.; Sanders, Lee M. (AAAI Press, 2014)
      Children with complex health conditions require care from a large, diverse set of caregivers that includes parents and community support organizations as well as multiple types of medical professionals. Coordination of ...
    • Applying MDP Approaches for Estimating Outcome of Interaction in Collaborative Human-Computer Settings 

      Kamar, Ece; Grosz, Barbara (2007)
      This paper investigates the problem of determining when a computer agent should interrupt a person with whom it is working collaboratively as part of a distributed, multi-agent team, which is operating in environments in ...
    • Attention, Intentions, and the Structure of Discourse 

      Grosz, Barbara; Sidner, Candace L. (Association for Computational Linguistics/MIT, 1986)
      In this paper we explore a new theory of discourse structure that stresses the role of purpose and processing in discourse. In this theory, discourse structure is composed of three separate but interrelated components: the ...
    • "But you Promised": Methods to Improve Crowd Engagement In Non-Ground Truth Tasks 

      Elmalech, Avshalom; Grosz, Barbara J. (2017)
      Crowdsourcing platforms were initially designed to recruit people to perform tasks that were simple cognitively but difficult for computers. One challenge in these settings is to identify an incentive mechanism for ...
    • Centering: A Framework for Modeling the Local Coherence of Discourse 

      Grosz, Barbara; Joshi, Aravind; Weinstein, Scott (Association for Computational Linguistics/MIT, 1995)
      This paper concerns relationships among focus of attention, choice of referring expression, and perceived coherence of utterances within a discourse segment. It presents a framework and initial theory of centering intended ...
    • Centering: A Framework for Modelling the Local Coherence of Discourse 

      Grosz, Barbara J.; Joshi, Aravind K.; Weinstein, Scott (1995)
      Our original paper (Grosz, Joshi, and Weinstein, 1983) on centering claimed that certain entities mentioned in an utterance were more central than others and that this property imposed constraints on a speaker's use of ...
    • Collaborative Health Care Plan Support 

      Amir, Ofra; Grosz, Barbara J.; Law, Edith Lok Man; Stern, Roni (ACM, 2013)
      This paper envisions a multi-agent system that assists patients and their health care providers. This system would support a diverse, evolving team in formulating, monitoring and revising a shared "care plan" that operates ...
    • Collaborative Plans for Complex Group Action 

      Grosz, Barbara; Kraus, Sarit (Elsevier, 1996)
      The original formulation of SharedPlans by B. Grosz and C. Sidner (1990) was developed to provide a model of collaborative planning in which it was not necessary for one agent to have intentions-to toward an act of a ...
    • Colored trails: A multiagent system testbed for decision-making research (demonstration) 

      Ficici, Sevan; Pfeffer, Avrom; Gal, Ya'akov Kobi; Grosz, Barbara; Shieber, Stuart (Association for Computing Machinery, 2008)
      With increasing frequency, computer agents participate in collaborative and competitive multiagent domains in which humans reason strategically to make decisions. The deployment of computer agents in such domains requires ...
    • A Combinatorial Auction for Collaborative Planning 

      Hunsberger, Luke; Grosz, Barbara (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      When rational, utility-maximizing agents encounter an opportunity to collaborate on a group activity they must determine whether to commit to that activity. We refer to this problem as the initial-commitment decision problem ...
    • Computing the communication costs of item allocation 

      Rauenbusch, Timothy W.; Shieber, Stuart; Grosz, Barbara (Association for Computing Machinery, 2005)
      Multiagent systems require techniques for effectively allocating resources or tasks to among agents in a group. Auctions are one method for structuring communication of agents’ private values for the resource or task to a ...
    • Conceptions of Limited Attention and Discourse Focus 

      Grosz, Barbara; Gordon, Peter (Association for Computational Linguistics/MIT, 1999)
      Walker (1996) presents a cache model of the operation of attention in the processing of discourse as an alternative to the focus space stack that was proposed previously by Grosz and Sidner (Grosz 1977a; Grosz and Sidner ...
    • Deploying Affect-Inspired Mechanisms to Enhance Agent Decision-Making and Communication 

      Antos, Dimitrios (2012-12-20)
      Computer agents are required to make appropriate decisions quickly and efficiently. As the environments in which they act become increasingly complex, efficient decision-making becomes significantly more challenging. This ...
    • Deploying AI Methods to Support Collaborative Writing: A Preliminary Investigation 

      Gehrmann, Sebastian; Urke, Lauren; Amir, Ofra; Grosz, Barbara J. (2015)
      Many documents (e.g., academic papers, government reports) are typically written by multiple authors. While existing tools facilitate and support such collaborative efforts (e.g., Dropbox, Google Docs), these tools lack ...
    • Determining the Value of Information for Collaborative Multi-Agent Planning 

      Sarne, David; Grosz, Barbara J. (Springer Verlag, 2013)
      This paper addresses the problem of computing the value of information in settings in which the people using an autonomous-agent system have access to information not directly available to the system itself. To know whether ...
    • DIALOGIC: A Core Natural-Language Processing System 

      Moore, Robert; Robinson, Jane; Grosz, Barbara; Martin, Paul; Hobbs, Jerry; Haas, Norman; Rosenschein, Stanley J.; Hendrix, Gary (Association for Computational Linguistics/ Academia Praha, Czechoslovakia, 1982)
      The DIALOGIC system translates English sentences into representations of their literal meaning in the context of an utterance. These representations, or "logical forms," are intended to be a purely formal language that is ...
    • Discourse structure and intention recognition. 

      Lochbaum, Karen; Grosz, Barbara J.; Sidner, Candace (Marcel Dekker, 2000)
    • Discourse Structure in Spoken Language: Studies on Speech Corpora 

      Nakatani, Christine; Hirschberg, Julia; Grosz, Barbara (Assocation for the Advancement of Artifical Intelligence, 1995)
      A better understanding of the intonational characteristics of spoken discourse may lead to new empirical techniques for identifying discourse structure from speech, as well as new algorithms for enhancing the naturalness ...
