<scribe> meeting: Chemistry for the Web and Publishing

Semantics of Chemistry in MathML

<scribe> Scribe: George

CS: I will lead the discussion

Dan is on the call as well.

CS: I missed the MathML call, and today we want to focus on Chemistry related matters in MathML.

NS: MathML group is a refresh CG. MathML 4 is one focus that will work well with browsers. Igalia is doing great work that will work with Chrom.

Their code base is going into Chromium. By the fall of 2020 we expect Chrom will display MathML natively. We want to masure the other browsers will follow the same approach to get identical presentation of MathML on the web.

The sccond track is to add semantics. There has always been a presentation layer and a content.

The second track is to "allow" to have authors add more semantics to their content.

This would allow applications like TTS, do not need to guess.

We want to be able to disambiguate.

We have a math-role that can add semantics. This name will probably change.

NS: is giving examples of the disambuigation.
... getting to Chemistry, we can guess that this expression is water, but if we put in a "subject" area we then know that this relates to Chemistry.

CML is a much more structured approach.

MS: what I really want from this group is what are the things that are ambigious?

I have tried to add what I know in the document, but Chemistry and this group can provide.

CS: S and P are two items that have two meanings.

F is another item.

NS: I am adding things to the document.

GK: I will not add these details to these notes, because they are going into the semantics document.

DB: I will I will send feedback on how to read documents.

NS: I have focused on on the disambiguation. I will also look at speaking rules.

CS: beside the speech, how does this impact braille rendering.

<volker> q

NS: if you know it is Chemistry, then the braille translator can focus on those rules.

<volker> queue

Volker: Have you ever learned Chemistry Braille notation?

<volker> http://www.brl.org/chemistry/

Anybody on the call know chem braille notation?

CS: I do know it is being used.

<Dan_B> George: Ability to disambiguate would give the richest experience.

<Dan_B> George: Will these attributes be hard coded or it will be a seperate doc?

NS: The attribute names will be added to the specification.

The values will probably be an external document that can change over time.

<Dan_B> Neil: Attribute names will be hard coded, but the values will change. We haven't quite resolved how to do this yet. We don't know if values will be in the spec or come later on.

We need to figure out how those values may be in an appendix or in some other document.

CS: the different branches of chemistry exists.

NS: at the moment we don't have the sub divisions. Physical chemistry, for example.

DB: If I have equations in my book, who adds the markup.

<Michael_Panno> queue

NS: there will be some kind of tool that is used, and it depends on the tool on what markup is produced.

The idea is to "allow" to add the additional information. It may be that the document is enhanced to add this semantic information.

GK: Does it change the presentation or content?

NS: This is purely for interreperation. We are looking at what people are actually using, which is presentational MathML, so you are adding more information.

JW: Are there different areas that require different markup?

CS: There are many different domains so, the H can have different semantics.

GK: if you have different subjects does it ripple through?

NS: that is the point to identify the defaults that work most of the time. There would be the need to markup the item if it is different than the default.
... we also need to explore the size of the context before you can correctly infer the semantics.

Blare Brown: On the publishing if we cannot get it into the tool, we will never be able to include this in the distributedd publication.

We have so much trouble already, and we see that this may really help us.

We would love to push this on our side.

NS: One thing there is a LaTex system called pretext that allows for a process for semantic disambituation.

If you could do this with a Chem book where the semantics are ambigitious. Get in touch with me and we can add them to this work.

CS: A lot of chem symboloty is contectual. The challange is toget the software to properly read the information.

The student's perspective is that this information is so contextual that the presentation and speech needs to be correct.

NS: is it important to present the speech information in particular ways?

Do you want to force an exact speech.

CS significant figures is important to get it right.

TS: was that you who were asking for content in LaTex?

NS: If you have LaTex and call out the items that are ambigious then this information would be useful to us. These real world examples are important to get to us.

TS: we have many journals in LaTex and I can put them in touch with you.

DB: MathML, LaTex, Aria are confusing. What is what?
... MathML, LaTex, Aria are confusing. What is what?

NS: the defaults and the exceptions are important to

Next call will be January 9 at the same time. GK will send out the invite.
