In this paper, we describe the Adaptive Place Advisor, a user adaptive, conversational recommendation system designed to help users decide on a destination, specifically a restaurant. We view the selection of destinations as an interactive, conversational process, with the advisory system inquiring about desired item characteristics and the human responding. The user model, which contains preferences...
This chapter introduces the field of natural language processing to the computer scientist or logician outside of the field. We first discuss some concepts from the field of linguistics, which focuses on the language half of the NLP equation, then move on to some of the common computational methods used to process and understand language. No previous knowledge of NLP is assumed.
Determining the semantic role of sentence constituents is a key task in determining sentence meanings lying behind a veneer of variant syntactic expression. We present a model of natural language generation from semantics using the FrameNet semantic role and frame ontology. We train the model using the FrameNet corpus and apply it to the task of automatic semantic role and frame identification, producing...
In this chapter, we present relational learning algorithms for two natural language processing tasks, semantic parsing and information extraction. We describe the algorithms and present experimental results showing their effectiveness. We also describe our application of active learning techniques to these learning systems.We applied certainty-based selective sampling to each system, using fairly...
We developed a measure of work-family culture (i.e., the shared assumptions, beliefs, and values regarding the extent to which an organization supports and values the integration of employees' work and family lives) and examined its relationship to work-family benefit utilization, organizational attachment, and work-family conflict. Using survey data from 276 managers and professionals, we identified...
The authors surveyed 86 pregnant women (73%White, 8% Asian, 7% African American, 6% Hispanic, and1% Native American) to examine individual andorganizational factors associated with organizationalcommitment and planned timing of their maternity leavesand return to work after childbirth.
