On the Potential of Lexico-logical Alignments for Semantic Parsing to SQL Queries [article]

Tianze Shi, Chen Zhao, Jordan Boyd-Graber, Hal Daumé III, Lillian Lee
2020 arXiv   pre-print
Large-scale semantic parsing datasets annotated with logical forms have enabled major advances in supervised approaches. But can richer supervision help even more?  ...  We propose and test two methods: (1) supervised attention; (2) adopting an auxiliary objective of disambiguating references in the input queries to table columns.  ...  Acknowledgments We thank the members of UMD CLIP, Xilun Chen, Jack Hessel, Thomas Müller, Ana Smith, and the anonymous reviewers and meta-reviewer for their suggestions and comments.  ...

From information to knowledge

Gerhard Weikum, Martin Theobald
2010 Proceedings of the twenty-ninth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems of data - PODS '10  
There are major trends to advance the functionality of search engines to a more expressive semantic level.  ...  The goal is to automatically construct and maintain a comprehensive knowledge base of facts about named entities, their semantic classes, and their mutual relations as well as temporal contexts, with high  ...  For a universal knowledge base, one would need to process a very large set of Web sources, potentially on a daily basis, as the world progresses rapidly.  ...

Question answering over knowledge bases with continuous learning [article]

Abdalghani Abujabal, Universität Des Saarlandes, Universität Des Saarlandes
2019
Templates are an important asset for QA over KBs, simplifying the semantic parsing of input questions and generating formal queries for interpretable answers.  ...  For issue (iii), we introduce a neural network model based on subword units for named entity recognition. The model learns word representations using a combination of characters, bytes and phonemes.  ...  Next, nodes in the dependency parse of u are aligned with semantic items in q.  ...

Integrating deep and shallow natural language processing components : representations and hybrid architectures [article]

Ulrich Schäfer, Universität Des Saarlandes, Universität Des Saarlandes
2007
We describe basic concepts and software architectures for the integration of shallow and deep (linguistics-based, semantics-oriented) natural language processing (NLP) components.  ...  WHITEBOARD is the first hybrid architecture to integrate not only part-of-speech tagging, but also named entity recognition and topological parsing, with deep parsing.  ...  XQuery adopts from SQL the FLWOR query concept (FLWOR for the for-letwhere-order-return query structure, loosely analogous to SQL's SELECT-FROM-WHERE) and combines it with XPath 2.0 to a powerful query  ...

Computer Systems and Software Engineering  
Even if one is able to bridge across these formats and paradigms to interoperate a new application, one crucial consideration is the semantic interoperability to insure that similar data is reconciled  ...  The design and deployment of an ontology for any system is very specific, created in isolation to suit the specific needs with limited reuse in the same domain.  ...  There was a similar convergence in the database community, first on standardizing the Structure Query Language (SQL) and later in the use of XML and XMI to export/import both a database schema and the  ...
