Keyword-Based Search Over Databases: A Roadmap for a Reference Architecture Paired with an Evaluation Framework [chapter]

Sonia Bergamaschi, Nicola Ferro, Francesco Guerra, Gianmaria Silvello
2016 Lecture Notes in Computer Science  
To overcome this issue, keyword search in databases is becoming the technology of choice, even if it suffers from efficiency and effectiveness problems that prevent it from being adopted at Web scale.  ...  In this paper, we motivate the need for a reference architecture for keyword search in databases to favor the development of scalable and effective components, also borrowing methods from neighbor fields  ...  Structured Query Language (SQL) queries over relational databases or SPARQL Protocol and RDF Query Language (SPARQL) queries over Linked Data graphs.  ...

A Path-Oriented RDF Index for Keyword Search Query Processing [chapter]

Paolo Cappellari, Roberto De Virgilio, Antonio Maccioni, Mark Roantree
2011 Lecture Notes in Computer Science  
Most of the recent approaches to keyword search employ graph structured representation of data. Answers to queries are generally sub-structures of the graph, containing one or more keywords.  ...  In this paper, we present an indexing scheme for RDF that exposes the structural characteristics of the graph, its paths and the information on the reachability of nodes.  ...  , a graph-oriented logical data model) datasets from data that had previously been stored using traditional models [1] , contributing to the definition of what is today called the Web of Data.  ...

Tejashree R. Shinde, Prof. Sanchika A. Bajpai
2015 International Journal of Engineering Research and  
In this information searching is done with the help of keyword which is known as query keyword and searching is called as keyword searching.  ...  In day to day life every person need some information which can be extracted from web through the various search engine.  ...  XRANK considers element to element links in addition to document to document links. 5) Keyword Search over Linked Data Existing work on keyword search relies on an elementlevel model (data graphs) to  ...

VisiNav: A system for visual search and navigation on web data

Andreas Harth
2010 Journal of Web Semantics  
In this paper we introduce a formal query model comprised of four atomic operations over object-structured datasets: keyword search, object focus, path traversal, and facet specification.  ...  To this end, we present VisiNav, a system based on an interaction model designed to easily search and navigate large amounts of web data (the current system contains over 18.5m RDF triples aggregated from  ...  Introduction Keyword search over hypertext documents is an established technology and is used by a large majority of web users [14] .  ...

Graph-of-Entity: A Model for Combined Data Representation and Retrieval

José Devezas, Carla Lopes, Sérgio Nunes, Michael Wagner
2019 Symposium on Languages, Applications and Technologies  
We tackle entity-oriented search using graph-based approaches for representation and retrieval.  ...  Modern search is heavily powered by structured knowledge, but users still query using keywords or, at the very best, telegraphic natural language.  ...  In this section, we approach the literature about graph-based entity-oriented search by covering two main aspects: entity-oriented search and graph-based search. Entity-oriented search.  ...

Thesaurus-Based Search in Large Heterogeneous Collections [chapter]

Jan Wielemaker, Michiel Hildebrand, Jacco van Ossenbruggen, Guus Schreiber
2008 Lecture Notes in Computer Science  
In the context of the E-Culture demonstrator we have shown earlier that such virtual collections can be effectively explored with keyword search and semantic clustering.  ...  In this paper we describe the design rationale of ClioPatria, an open-source system which provides APIs for scalable semantic graph search.  ...  to the graph search API are: -abstract(Boolean): enables the abstraction of the graph search paths over rdfs:subClassOf and rdfs:subPropertyOf, reducing the number of clusters.  ...

IQ: The Case for Iterative Querying for Knowledge

Yosi Mass, Maya Ramanath, Yehoshua Sagiv, Gerhard Weikum
2011 Conference on Innovative Data Systems Research  
This calls for going beyond keyword search, towards more expressive ways of entity-relationship-oriented querying with graph constraints or even full-fledged languages like SPARQL (over graph-structured  ...  We present two instantiations for IQ, one based on keyword search over labeled graphs combined with structural constraints, and another one based on extensions of the SPARQL language.  ...  There are other systems for keywords search over data graph [11] , but only [1] facilitates search in both dimensions, namely, answers and their schemas.

AN APPROACH TO EXTENDING QUERY SENTENCE FOR SEMANTIC ORIENTED SEARCH ON KNOWLEDGE GRAPH

TẠ DUY CÔNG CHIẾN
2021 Journal of Science and Technology - IUH  
Therefore, this paper introduces an approach to extending query sentences for semantic oriented search on knowledge graph.  ...  However, using relational databases do not sufficiently support the semantic orientated search by Structured Query Language (SQL) and the searching speed is slow.  ...  In general, there are many researches relevant to semantic orientation extraction and semantic search over relational databases.  ...

Andreas Wagner, Günter Ladwig, Thanh Tran
2011 Lecture Notes in Computer Science  
Faceted search enables users to browse and discover relevant items from a large collection such as the Web of data.  ...  Existing faceted search solutions assume a precise information need, and thus optimise relevance, interestingness, and costs of fulfilling an information need.  ...  Data, Query and Facet Model Data and Query Model. As different types of structured Web data may be represented as graphs (including RDF), we employ a general graph-structured data model.  ...
