CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines
Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective.
The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines.
From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research
A Technology Proposal for a Management Information System for the Director’s Office, NAL.
This technology proposal attempts in giving a viable solution for a Management Information System (MIS) for the Director's Office. In today's IT scenario, an Organization's success greatly depends on its ability to get accurate and timely data on its operations of varied nature and to manage this data effectively to guide its activities and meet its goals. To cater to the information needs of an Organization or an Office like the Director's Office, information systems are developed and deployed to gather and process data in ways that produce a variety of information to the end-user. MIS can therefore can be defined as an integrated user-machine system for providing information to support operations, management and decision-making functions in an Organization. The system in a nutshell, utilizes computer hardware and software, manual procedures, models for analysis planning, control and decision-making and a database. Using state-of-the-art front-end and back-end web based tools, this technology proposal attempts to provide a single-point Information Management, Information Storage, Information Querying and Information Retrieval interface to the Director and his office for handling all information traffic flow in and out of the Director's Office
Data integration support for offshore decommissioning waste management
Offshore oil and gas platforms have a design life of about 25 years whereas the techniques and tools
used for managing their data are constantly evolving. Therefore, data captured about platforms during
their lifetimes will be in varying forms. Additionally, due to the many stakeholders involved with a facility
over its life cycle, information representation of its components varies. These challenges make data
integration difficult. Over the years, data integration technology application in the oil and gas industry
has focused on meeting the needs of asset life cycle stages other than decommissioning. This is the
case because most assets are just reaching the end of their design lives.
Currently, limited work has
been done on integrating life cycle data for offshore decommissioning purposes, and reports by industry
stakeholders underscore this need.
This thesis proposes a method for the integration of the common data types relevant in oil and gas
decommissioning. The key features of the method are that it (i) ensures semantic homogeneity using
knowledge representation languages (Semantic Web) and domain specific reference data (ISO 15926);
and (ii) allows stakeholders to continue to use their current applications. Prototypes of the framework
have been implemented using open source software applications and performance measures made.
The work of this thesis has been motivated by the business case of reusing offshore decommissioning
waste items. The framework developed is generic and can be applied whenever there is a need to
integrate and query disparate data involving oil and gas assets. The prototypes presented show how
the data management challenges associated with assessing the suitability of decommissioned offshore
facility items for reuse can be addressed. The performance of the prototypes show that significant time
and effort is saved compared to the state-of‐the‐art solution. The ability to do this effectively and
efficiently during decommissioning will advance the oil the oil and gas industry’s transition toward a
circular economy and help save on cost
