Language Model Based Arabic Word Segmentation

Authors: nan

Publication: TIPSTER (2003)

DOI: nan

We approximate Arabic’s rich morphology by a model that a word consists of a sequence of morphemes in the pattern prefix*-stem-suffix* (* denotes zero or more occurrences of a morpheme). …...

Abstract Syntax Networks for Code Generation and Semantic Parsing

Authors: nan

Publication: TIPSTER (2017)

DOI: nan

AbstractTasks like code generation and semantic parsing require mapping unstructured (or partially structured) inputs to well-formed, executable outputs. We introduce abstract syntax networks, a modeling framework for these problems. The …...

Cross-Domain Generalization of Neural Constituency Parsers

Authors: nan

Publication: TIPSTER (2019)

DOI: nan

AbstractNeural parsers obtain state-of-the-art results on benchmark treebanks for constituency parsing—but to what degree do they generalize to other domains? We present three results about the generalization of neural parsers …...

RAT-SQL: Relation-Aware Schema Encoding and Linking for Text-to-SQL Parsers

Authors: nan

Publication: TIPSTER (2020)

DOI: nan

AbstractWhen translating natural language questions into SQL queries to answer questions from a database, contemporary semantic parsing models struggle to generalize to unseen database schemas. The generalization challenge lies in …...

Chase: A Large-Scale and Pragmatic Chinese Dataset for Cross-Database Context-Dependent Text-to-SQL

Authors: nan

Publication: TIPSTER (2021)

DOI: nan

AbstractThe cross-database context-dependent Text-to-SQL (XDTS) problem has attracted considerable attention in recent years due to its wide range of potential applications. However, we identify two biases in existing datasets for …...

Bridging the Gap between Synthetic and Natural Questions via Sentence Decomposition for Semantic Parsing

Authors: nan

Publication: TIPSTER (2023)

DOI: nan

AbstractSemantic parsing maps natural language questions into logical forms, which can be executed against a knowledge base for answers. In real-world applications, the performance of a parser is often limited …...

Context Generation Improves Open Domain Question Answering

Authors: nan

Publication: TIPSTER (2023)

DOI: nan

AbstractClosed-book question answering (QA) requires a model to directly answer an open-domain question without access to any external knowledge. Prior work on closed-book QA either directly finetunes or prompts a …...
