Topic-based browsing within a digital library using keyphrases

Steve Jones, Gordon Paynter
1999 Proceedings of the fourth ACM conference on Digital libraries - DL '99  
Automatic keyphrase extraction is exploited to identify link anchors, and keyphraseÐbased similarity measures are used to select and rank destinations.  ...  Two implementations are described: one that applies these techniques to existing WWWÐbased digital library collections using standard HTML, and one that uses a wider range of interface techniques to provide  ...  Many thanks also to Carl Gutwin for implementation of the first Phrasier prototype, and producing the keyphrase indexes originally used by Phrasier.  ...

Improving browsing in digital libraries with keyphrase indexes

Carl Gutwin, Gordon Paynter, Ian Witten, Craig Nevill-Manning, Eibe Frank
1999 Decision Support Systems  
Automatically-extracted keyphrases form the basic unit of both indexing and presentation, allowing users to interact with the collection at the level of topics and subjects rather than words and documents  ...  Conventional systems often operate at the wrong level, indexing words when people think in terms of topics, and returning documents when people want a broader view.  ...  Kea, the system used to extract keyphrases for Keyphind, is available from www.nzdl.org/Kea/.  ...

Learning Feature Representations for Keyphrase Extraction [article]

Corina Florescu, Wei Jin
2018 arXiv   pre-print
Our model represents the document as a graph and automatically learns feature representation of phrases. The proposed model obtains remarkable improvements in performance over strong baselines.  ...  In supervised approaches for keyphrase extraction, a candidate phrase is encoded with a set of hand-crafted features and machine learning algorithms are trained to discriminate keyphrases from non-keyphrases  ...  Introduction Keyphrase extraction (KE) is the task of automatically extracting descriptive phrases or concepts that represent the main topics of a document.  ...

WikiRank: Improving Keyphrase Extraction Based on Background Knowledge [article]

Yang Yu, Vincent Ng
2018 arXiv   pre-print
Keyphrase is an efficient representation of the main idea of documents.  ...  In this paper, we propose WikiRank, an unsupervised method for keyphrase extraction based on the background knowledge from Wikipedia. Firstly, we construct a semantic graph for the document.  ...  Automatic keyphrase extraction concerns "the automatic selection of important and topical phrases from the body of a document".  ...

Creation and evaluation of large keyphrase extraction collections with multiple opinions

Lucas Sterckx, Thomas Demeester, Johannes Deleu, Chris Develder
2017 Language Resources and Evaluation  
A first systematic evaluation of ranking and classification of keyphrases using both unsupervised and supervised AKE techniques on the test collections shows a superior effectiveness of supervised models  ...  While several Automatic Keyphrase Extraction (AKE) techniques have been developed and analyzed, there is little consensus on the definition of the task and a lack of overview of the effectiveness of different  ...  known as Flanders Innovation & Entrepreneurship) and Innoviris.  ...
