Now is the era of cloud computing and related buzzwords are the virtualization, resource sharing, Big Data. With the advent of new technologies, gadgets or simply IOT has enabled the advanced connectivity of devices, systems, and services and with this the data is being produced at an enormous rates from these devices be it form sensors, GPS data, log files from different sources etc. which is ...

One of the key advantages of XML is its capacity to combine structured and unstructured (text) data. Many languages, based on database-oriented approaches or on information retrieval-oriented approaches, have been proposed in the literature for querying XML corpus. However, they respectively accentuate document structure querying or text querying, but they do not manage to combine it in an attr...

A model to query document databases by both their content and structure is presented. The goal is to obtain a query language which is expressive in practice while being eeciently imple-mentable, features not present at the same time in previous work. The key ideas of the model are a set-oriented query language based on operations on nearby structure elements of one or more hierarchies, together...

Japio performs various patent-related translation businesses, and owns the original patent-documentderived bilingual technical term database (Japio Terminology Database) to be served for the translators. Currently the database contains more than 780,000 J-E technical terms. To adapt the database to the Patent Translation Task, Japio compiled machine translation dictionaries from it. 34 technica...

The design and performance of a system for spotting handwritten Arabic words in scanned document images is presented. Three main components of the system are a word segmenter, a shape based matcher for words and a search interface. The user types in a query in English within a search window, the system finds the equivalent Arabic word, e.g., by dictionary look-up, locates word images in an inde...

Schemaless databases, and document-oriented databases in particular, are preferred to relational ones for storing heterogeneous data with variable schemas and structural forms. However, the absence of a unique schema adds complexity to analytical applications, in which a single analysis often involves large sets of data with different schemas. In this paper we propose an original approach to OL...

This chapter introduces a complete storage and retrieval architecture for a database environment for XML documents. DocBase, a prototype system based on this architecture, uses a flexible storage and indexing technique to allow highly expressive queries without the necessity of mapping documents to other database formats. DocBase is an integration of several techniques that include (i) a formal...
