When and how to use the Query tab?

You can use the Query tab when you are looking for results featuring one specific characteristic (a type of biomass or pretreatment e.g.) and/or specific values (an interval of glucose yield values e.g.). You can also use Query if you are looking for a specific paper which you don’t remember the name but only a few characteristics (cf. I would like to access an annotated paper but I can’t find it. Where and how can I look for it?).

On how to use Query, refer to the Querytutorials.

Here is an example of querying in biorefinery:  let’s say you want to look for a document which you remember features biomass crystallinity values around 2% you will select the relation Biomass crystallinity relation in the Query scope and then go to the second step of querying, defining value domains. Select crystallinity in the attribute pull-down menu and then click on define value domain. Here you can choose the interval you will accept to have values in and also the interval in which the best values should be. You will then need to precise if the intervals you have chosen are going to be mandatory or desirable in your query. Here, since you are looking for 2% crystallinity, you can have a preferred interval of 0-5% and an acceptable interval of 0-10%, both listed as mandatory.

You can also specify the reliability of the paper if you know it in the step define values parameters, and/or choose a topic (according to the sequel of pretreatments you think the paper describes) in the query scope.

The more you refine your query, the more your query results will be narrowed down.
