Keyword search in geospatial database
Proceedings of the 18th SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2010Geospatial databases usually contain features of different geometries, associated with thematic attributes. The features have implicit spatial relationships which are not explicitly captured (unless the relationships have their own attributes, which is rare), and hence geospatial databases contain a few or no foreign keys.

Pattern Exploration as Keyword Search
2020 IEEE International Conference on Big Data (Big Data), 2020Frequent pattern mining is one of the central tasks in data mining with broad applications in diverse domains. The mining process typically returns an overwhelmingly large number of patterns, making pattern evaluation and exploration extremely difficult.

Subword scheme for keyword search
2014 IEEE Spoken Language Technology Workshop (SLT), 2014Keyword search (KWS) is an important application of spoken language technology. The technique of Large Vocabulary Continuous Speech Recognition (LVCSR) is playing an important role in KWS system. However, for a language with large vocabulary and relatively insufficient text corpus, the vocabulary size keeps going up very quickly with the increasing ...

Strategies for Vietnamese keyword search
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014We propose strategies for a state-of-the-art Vietnamese keyword search (KWS) system developed at the Institute for Infocomm Research (I 2 R). The KWS system exploits acoustic features characterizing creaky voice quality peculiar to lexical tones in Vietnamese, a minimal-resource transliteration framework to alleviate out-ofvocabulary issues from ...

Keyword Searching in Hypercubic Manifolds
Fifth IEEE International Conference on Peer-to-Peer Computing (P2P'05), 2005The authors presented a novel approach for keyword searching for file sharing applications based on a simple hash function and extension to current distributed hash tables (DHT) topology. Depart from standard hash methods on DHT systems, this approach is to develop a locality preserving hash function so that objects containing the same keyword tend to ...

Searching activity trajectory with keywords
World Wide Web, 2018Driven by the advances in location positioning techniques and the popularity of location sharing services, semantic enriched trajectory data has become unprecedentedly available. While finding relevant Point-of-Interests (PoIs) based on users’ locations and query keywords has been extensively studied in the past years, it is, however, largely untouched

Oblivious Conjunctive Keyword Search
2006We study the problem of keyword search in which a server contains various multimedia contents and a user of server wishes to retrieve some multimedia item containing specific keywords without revealing to the server which item it is. Recently, Ogata and Kurosawa introduced an interesting keyword search scheme called oblivious keyword search by using ...

Negation in Relational Keyword Search
2019Keyword search in relational databases frees users from writing complicated SQL queries. However, negation is still not allowed in keyword queries, limiting its expressiveness. This work addresses the problem of supporting negation in keyword queries. Our solution considers the keyword matches and the scope of negation.

Proceedings of the 2009 ACM SIGMOD International Conference on Management of data, 2009
Keyword search in relational databases (RDBs) has been extensively studied recently. A keyword search (or a keyword query) in RDBs is specified by a set of keywords to explore the interconnected tuple structures in an RDB that cannot be easily identified using SQL on RDBMS.
