Fast statistical parsing of noun phrases for document indexing

Chengxiang Zhai
1997 Proceedings of the fifth conference on Applied natural language processing -  
This paper proposes a new probabilistic model for noun phrase parsing, and reports on the application of such a parsing technique to enhance document indexing.  ...  The experiment's results show that supplementing single words with syntactic phrases for indexing consistently and significantly improves retrieval performance.  ...  Naturally, the author alone is responsible for all the errors.  ...

Systems AI: A Declarative Learning Based Programming Perspective

Parisa Kordjamshidi, Dan Roth, Kristian Kersting
2018 Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence  
We review key efforts made by various AI communities to provide languages for high-level abstractions over learning and reasoning techniques needed for designing complex AI systems.  ...  Unfortunately, current technologies do not make such techniques easy to use for application experts who are not fluent in machine learning nor for machine learning experts who aim at testing ideas on real-world  ...  For example, we can have all phrases in a relational database and query for all pairs of phrases that have a specific distance between them in the sentence.  ...

Unsupervised Concept Categorization and Extraction from Scientific Document Titles

Adit Krishnan, Aravind Sankar, Shi Zhi, Jiawei Han
2017 Proceedings of the 2017 ACM on Conference on Information and Knowledge Management - CIKM '17  
In the second phase, we propose an approach based on adaptor grammars to extract fine grained concept mentions from the aspect-typed phrases without the need for any external resources or human effort,  ...  We apply our technique to study literature from diverse scientific domains and show significant gains over state-of-the-art concept extraction techniques.  ...  Phrase mining techniques such as [3] and [10] study the extraction of signi cant phrases from large corpora, however they do not factor aspects or typing of phrases in the extraction process.  ...

Handling Uncertainty in Information Extraction

Maurice van Keulen, Mena B. Habib
2011 International Semantic Web Conference  
We discuss the problem of managing and manipulating probabilistic dependencies.  ...  This position paper proposes an interactive approach for developing information extractors based on the ontology definition process with knowledge about possible (in)correctness of annotations.  ...  Although many probabilistic and fuzzy techniques abound, some aspects often remain absolute: extraction rules absolutely recognize and annotate a phrase or not, only a top item from a ranking is chosen  ...

Probabilistic question answering on the Web

Dragomir Radev, Weiguo Fan, Hong Qi, Harris Wu, Amardeep Grewal
2005 Journal of the American Society for Information Science and Technology  
The process entails five steps: query modulation, document retrieval, passage extraction, phrase extraction, and answer ranking.  ...  In this paper we describe some probabilistic approaches to the last three of these stages. We show how our techniques apply to a number of existing search en-answering.  ...  The PPR technique (Probabilistic Phrase Reranking) relies on an existing search engine to return documents that are likely to contain the answer to a user question.  ...
