2013 Proceedings of the 2013 international conference on Management of data - SIGMOD '13  
In this paper, we propose a new approach of building a massively-parallel search engine using a DB-IR tightly-integrated parallel DBMS.  ...  To estimate the performance, we propose a hybrid (i.e., analytic and experimental) performance model for the parallel search engine.  ...  Section 2 introduces techniques of DB-IR integration as a preliminary. Section 3 proposes the architecture of ODYS, a massively parallel search engine using a DB-IR tightly integrated parallel DBMS.  ...

DB-IR integration using tight-coupling in the Odysseus DBMS

Kyu-Young Whang, Jae-Gil Lee, Min-Jae Lee, Wook-Shin Han, Min-Soo Kim, Jun-Sung Kim
2013 World wide web (Bussum)  
ACM SIGMOD discusses application of the Odysseus DBMS to a massively-parallel search engine architecture.  ...  As many recent applications require integration of structured data and text data, unifying database (DB) and information retrieval (IR) technologies has become one of major challenges in our field.  ...  Since this engine is mainly based on prefix search (IR features) and join (DB features), it can be considered as one of DB-IR integration systems.  ...

D-Hive: Data Bees Pollinating RDF, Text, and Time

Srikanta J. Bedathur, Klaus Berberich, Ioannis Patlakas, Peter Triantafillou, Gerhard Weikum
2013 Conference on Innovative Data Systems Research  
Although the problem of integrating IR and DB solutions is considered "old", the increasing importance of big data analytics and its formidable demands for both enriched functionality and scalable performance  ...  Our goal is to develop a system that will make large corpora aware of entities and relationships (ER), addressing the challenges in searching and analyzing ER patterns in web data and social media.  ...  We are convinced that now is the right time to reconsider and advance the cross-pollination of DB and IR methods at Web scale for analytics applications that need to integrate RDF, text, and time.  ...

A COMPARATIVE STUDY AMONG THE MAIN CATEGORIES OF NoSQL DATABASES

2020 Al-Azhar Bulletin of Science  
But when it comes to Bigdata, we need to use more flexible databases that satisfy the need to handle semi-structured and unstructured data. These databases are called NoSQL (Not only SQL) databases.  ...  This paper's main purpose is to present a comparative study of the five main categories of NoSQL databases; key-value stores, document stores, column family stores, graph stores databases, and object store  ...  Column Stores are designed to deliver random, real-time, and read or write access to huge data and to run Map Reduce jobs on huge databases; Search engines and Analyzing log data.  ...

Iterative Query Refinement for Exploratory Search in Distributed Heterogeneous Linked Data

Laurens De Vocht
2015 International Semantic Web Conference  
We show that the set of techniques facilitates web applications in fulfilling task-oriented searches more effectively and that user interaction with search results indeed gradually refines search queries  ...  Formulating a search query is particularly difficult in case of distributed Linked Data sources, because they have many different relationships and vocabularies.  ...  I would like to thank my supervisors: Ruben Verborgh, Erik Mannens and Rik Van de Walle, for their support and the opportunity for the realization of this work.  ...

Boyu Ning, Zhongbao Tian, Zhi Chen, Chong Han, Shaoqian Li, Jinhong Yuan, Rui Zhang
2022 arXiv   pre-print
To compensate for the propagation loss, the ultra-massive multiple-input-multiple-output (UM-MIMO) can be applied to generate a high-gain directional beam by beamforming technologies.  ...  Specifically, we first present the system model of THz UM-MIMO and identify its channel parameters and architecture types.  ...  In the non-IRS-assisted scheme, we treat IRS as an indoor wall whose first-order ray attenuation is randomly set to between 5.8 dB and 19.3 dB compared to the LoS [207] .  ...

Big Data Analytics = Machine Learning + Cloud Computing [chapter]

Like Apache Lucene, it was not an executable search application rather than a toolkit or information retrieval (IR) library [65] .  ...  However, Lucene was not an executable application or search engine rather than a toolbox or searching tool kits that enable many applications to borrow or use it. Lucene is just classification index.  ...  Cafarella created it in early 2006, their original idea was to build Apache Nutch (or a web crawler engine) on a cheaper infrastructure.  ...
