A Semi-Supervised Learning Approach for Morpheme Segmentation for an Arabic Dialect
We evaluate our approach by applying morpheme segmentation to the training data of a statistical machine translation (SMT) system. Experiments show that our approach is less sensitive to the availability of annotated stems than a previous rule-based approach and learns 12% more segmentations on our Iraqi Arabic data.

Leveraging graph locality via abstraction
The use of abstraction to speedup problem solving is ubiquitous in AI, especially in the field of heuristic search where abstraction has proven a crucial technique for creating highly accurate memory-based heuristics known as pattern databases (PDBs).

Regression testing for grammar-based systems
This paper describes best practices in two closely related regression testing frameworks used in grammar-based systems: MedSLT, a spoken language translation system based on the Regulus platform, and a search and question answering system based on PARCs XLE syntax-semantics parser.

An LFG Chinese grammar for machine use
This paper describes the Chinese grammar developed at PARC, including its three basic components: the tokenizer and tagger, lexicon and syntactic rules.

PARC’s Bridge question answering system
This paper describes a system designed to robustly map from natural language sentences to logical, abstract knowledge representations (the Bridge system).

Results from Levels 2/3 Fusion Implementations: Issues, Challenges, Retrospectives and Perspectives for the Future an Annotated Perspective
This paper is a retrospective annotated view of the invited panel discussion organized by Ivan Kadar (first author), supported by John Salerno, in order to provide both a historical perspective of the evolution of the state-of-the-art (SOA) in higher-level “Levels 2/3” information fusion implementations by looking back over the past ten or more years (before…

Adapting Scenario-Based Curriculum Materials To Community College Technical Courses
This 3-year case study examined how 7 instructors and 78 students in California and Texas responded to the changes involved in implementing one type of reform program—the scenario-based curriculum.

Efficient Message Passing and Propagation of Simple Temporal Constraints
We first show that for an STN, these messages can be represented compactly as sub-STNs. We then present an efficient message passing scheme for computing the minimal constraints of an STN.
