Algae as a source of food
Microalgae as a food source for humans has beenconsidered for overpopulated countries and for spacetravel since as early as 1961.If algae is grown under proper environmental conditions,the protein yield from it may be quite high.Algae have been collected for more than 4000 years inChina and Japan for use as human food.Spirulina algae is considered to be one of the mostnutritious food on the planet.

Algaculture
Algal production operations can be quite diverse in the sizeof the plant and the scope of their produce.They vary from small units producing specialty chemicalsand nutraceuticals to large scale farms involved in theproduction of food products and biofuels.This diversity makes a uniform analysis of algalproductivity a challenging endeavour.

EnAlgae: Energetic Algae
Aims to reduce CO2 emissions and dependency onunsustainable energy sources in North West Europe.4 Year Strategic initiative of Interreg IVb NWE programme.
19 partners and 14 Observers across 7 EU states.
Coordinated set of activities focussing on sharing bestpractice, developing effective stakeholder engagement andencouraging transnational cooperation.

EnAlgae: Some of the objectives
Accelerate development of sustainable technologies forBiomass production.Create a network of pilot scale algal facilities across NWEin order to address the current lack of verifiable informationon algal productivity.Maintain an up to date inventory in which pilots collect andshare data in a standardised manner.Combine information across the entire algal bioenergydelivery chain into a comprehensive and user friendlyDecision Support System for practitioners, policy makersand investors

The problem
Lack of a unified underlying standard that provides a set ofmetrics to facilitate a uniform and accurate assessment ofthe economic and environmental footprint of theoperations.Lack of a shared, accumulative and consistent knowledgebase that can support funding bodies and investmentstakeholders in making decisions.

Minimum Descriptive Language(MDL)
Standard developed by the Algal Biomass Organisation(ABO),To uniformly capture the footprint of an algal productionoperation.To eliminate the prevailing heterogeneity in the recording ofplant-specific metricsTo facilitate the generation and sharing of a uniform andconsistent knowledge baseTo harmonise the terminology to be used acrossproduction operations and stakeholders.

OntoMDL
Advantages of building ontologies from standards
Already built-in-consensus on the use of key domainspecific terminologiesMinimal semantic loss as standards informally include therelationships between concepts and ease of knowledgetransfer.

Knowledge Acquisition Phase
An algal production unit can bea newly established plant with no access to knowledgebases from existing plants (Competitive markets can drivethe situation).a newly established plant which has access to and wouldlike to benefit from knowledge bases acquired fromexisting plants.an existing plant which would like to benefit from a wellrecorded history of knowledge bases.

[email protected] Semantic Web and Agri-Food, 13th June 2012
Assessment Phase
Assessment of identified standards, assessing otherontologies identified for reuse.Merging ontologies, reengineering ontologies.Refrain from using NLP techniques in the initial iterations.A detailed perusal of the standards by knowledgeengineers, guided by domain experts, for knowledgeextraction.Iterative evolution of the standards based on the ontologiesdeveloped.
After a few iterations of the standards-ontology mapping, NLPtechniques guided by the lessons learned can be explored.
