GUI design – conceptual, semantic, syntactic and lexical levels

In terms of symbols or icons, that can conceptual level is defined as the mental model of the viewer; semantic level is the meaning that it conveys; syntactic level is attributed to its aesthetic quality or its arrangement on the screen;

How would you describe that? "lexical level" in connection with the iconography?

Release Management – Switching to semantic versioning of simple version numbers

There is a software library / application / framework that currently uses "simple version numbers". So it is currently (say) version 135 and releases occur at irregular intervals when "enough for a new release exists". The next release would be 136 in this scheme.

I would like to change this to use the semantic versioning (version numbers) and Release behavior of course).

Which version should I use for the "first" semantic version?

That is, should be the next release 135.1.0 … or 136.0.0, Or 1.0.0? What is the "right" approach and what approach breaks the least number of version comparison algorithms?

Neural Networks – Placement of categorization and semantic mapping on a mobile robot

I am currently working on a project where I have to create a semantic map of the environment through which my robot moves. An RGB-D camera is mounted on the robot. So, as it moves through the environment, it can perceive a continuous stream of images, each directed through a CNN trained to identify various locations such as kitchen, elevator, corridor, door, etc., and the result the location classification is then iterated through a Bayesian filter to create an occupancy grid map of the environment that is labeled with different location categories (colors corresponding to different locations) as described in this document. An example is shown below:

Enter image description here

Now the problem is here, if you look at yourself Point X Although the robot is in the corridor at this time, the camera already recognizes an office (orange) and therefore identifies part of the corridor as an office.

I am looking for a solution to circumvent this and segment the map as accurately as possible in real time as the robot moves through the environment. This can also be done iteratively, z. For example, to refine the result when the robot crosses point X again sometime in the future.

P.S. The robot is also equipped with two laser rangefinders to create the occupancy map. Maybe I can somehow combine the laser range point cloud with the depth point cloud of the RGB D camera.

To create a semantic / accessible list using the Load More button

Here is a simple example of what I would like to do:


  • Item 1
  • Item 2
  • Item 3


// Pseudo code

Logically, it's a bit simple and it would work well with the keyboard. I'm not sure how to make this feature more accessible to screen readers, so I'll be alerted when new items are added to the list.

Does anyone have an option / kickstart how to do that?

I did not find anything in my search. Maybe I'm looking for the wrong keyword.

Thanks a lot!

seo – Semantic Markup itemprop Name / Description on multilingual website

I'd like to set up a semantic markup for products such as a language stay on a site that's available in fr, en, and it languages.

I wonder if I can have the name of the product and its description in its three languages! Example:

The page in French:


The same page in English:


Is it possible to have the name and description of a product in multiple languages ​​because they have the same unique itemprop / mpn code? Is it good for SEO or not recommended?

Thank you for your advice,

Semantic Versioning – How Does a Software Developer Perform Two Minor Updates Simultaneously?

In a web application I'm just creating, two smaller functions might be running at the same time: implementing a new web page and implementing the notification bar. After merging both in Master on GitHub and resolving existing conflicts, I'll release them.

My current version is v0.9.1

When I release it again, there are two new minor changes. Would it be 0.11.0, 0.10.0? The seems to give no insight into this scenario.

Note: I would ask this on webapps SE, but the semantic versioning does not have its own tag. It seemed more likely to get an answer on this page.

Semantic Web – When should the "mentions" property of be used for what kind of references?

The mentions Property can be used on Creative workSo everyone items and website, The value for this property is thing,

This gives the webmasters very comprehensive possibilities. In theory mentions should be used very often, but it is not really. Why? Do I misunderstand the definition of

Indicates that CreativeWork has a reference to a concept but does not necessarily refer to it.

Anytime the content of a web page contains a link to another web site or digital document on my server that can serve as a "reference" I can use it mentions Property, could not I? For example, I mention some references for my work on my aboutme page, may be a digital document (.jpg, .pdf, etc.) of my last course or an article about me on a website of the authority ect.

is mentions really the all-purpose weapon that I take or use better Quote Property for my purposes?
