GutenTag: A Multi-Term Caching Optimized Tag Query Processor for Key-Value Based NoSQL Storage Systems

However, NoSQL systems do not efficiently support services referring more than one data object, e.g. the term-based search for data objects. ...
To address this issue we propose our architecture based on an inverted index on top of a NoSQL system. ...
However, a keyword-based search solely using a singleterm inverted index scales poorly in terms of bandwidth consumption in large distributed systems. ...

Fundamental issues in text analysis include the lack of structure in document datasets, the need for various preprocessing steps %(e.g., stem or lemma extraction, part-of-speech tagging, named entities ...
Thus, we propose in this paper a new generic text analysis architecture, where document structure is flexible, many preprocessing techniques are integrated and textual datasets are indexed for efficient ...
DODBMSs are a class of NoSQL systems that aim to store, manage and process data using a semistructured model. DODBMSs encapsulate data in collections of documents [8] . ...
