I'm beginning in semantic web. I want to develop a semantic web recommend-er system. The most important part of my project is moddeling. How can I start it? How long does it take? What soft-wares or tools can I use to develop that?
You can use Protege Ontology Editor to create your data models and create semantic rules with SWRL. Also you need a semantic rule engine too.

JHipster provides some great tools for generating JPA entities and related objects and classes. The site showcases and describes comparisons between a few of these options:
Using a simple questionnaire entity-subgenerator (via jhipster entity) for generating very basic entities
Creating a UML with the JHipster-UML tool, or a similar UML tool
Using a DSL tool called JHipster-JDL with some nice IDE plugins or JDL-Studio
The Entity Sub-Generator (for beginners)
I've found that the entity-subgenerator is lacking for advanced users and is very limited on what it can do. However, it's great for new JHipster or Java/Spring users to understand what an entity is or how JHipster works regarding code generation.
JHipster-UML or JHipster-JDL (for advanced users)
That being the case, I'd only be interested in using JHipster-UML or JHipster-JDL for entity generation. My questions pertain just to those two techniques and when I would use JHipster-UML vs. JHipster-JDL:
What features does one have that the other does not have?
JHipster-JDL seems to have been created specifically for JHipster while JHipster-UML seems to use existing UML DSLs. Should I only use a UML tool only if I have some tool or language-familiarity preference?
These items are not clear on the docs on the website, so I'd love some clarification. Would be happy to update the OS docs to clarify this question for others not coming in with a preference for the two and trying to decide what direction to go with them.
JDL is more powerful than JHipster-UML because it has more features that go beyond class modeling like generating all your microservices applications at once from one file and JHipster 6 will add more features to JDL.
I usually recommend newcomers to start with entity sub generator because you don't have to learn a new language, you create few entities and then you use jhipster export-jdl to export these entities as JDL. From there you can easily switch to JDL only.
I'm trying to build my first app on Hybris, but I'm not sure what is the best approach to build such applications. Let's say I sell flowers in my store. Currently there are 2 ways how to do it:
Create accelerator template and then reconfigure application.
Building app from the beginning.
The first solution may look very attractive, but I don't think it is better solution because:
Hybris doesn't provide an accelerator for my specific solution (flowers), application reconfiguration may take a lot of time.
Some accelerators contain more that one store - other stores should be removed.
The mess in the database. I have to spend time and understand which tables should be removed.
The second approach seems the most logical, but in this case I have some doubts, because the speed of development will be significantly reduced. Moreover, I think that developing a simple store on Spring Boot will be much faster than learning the Hybris platform's extensions and how they work together.
In this case, how should I start develop my application?
Honestly, I don't have experience with building complete SAP Hybris application from the scratch yet, but I have some experience related to development of the SAP Hybris extensions, so I'll try to provide my potential approach because I don't see many answers here.
I'd do it as follows:
Get the whole commerce suite
Run one of the recipe with the installer script (choose one, which will be the best for you - one of the most popular/common recipes is b2c_acc)
Remove unwanted extensions from the localextensions.xml file if necessary
Add another extensions, if you need them
Depending on your use case, create your own extension basing on the one of templates with ant extgen task inside the hybris/bin/platform/ dir (e.g. yacceleratorstorefront, ybackoffice, yempty, etc.)
Add your custom extension (or extensions) to localextensions.xml file
Start your development within your custom extension created out of available template
I know, it's kind of "specific" platform. I hope this answer will help a bit.
Cheers
VS2013 update 5, MVC5 using Areas
I have a stand-alone function programmed for a website. The functionality is a specific user interface to collect survey responses in a particular way. It has several controllers, a model and a group of views. The functionality is completely contained in an Area of the project, except for the Shared _Layout file that provides the main menu for consistency.
'Is it possible for me to' / 'how do I' compile this Area into a single or set of .dll file(s) that I could then add conveniently to other websites? I'm assuming creating something for transfer/download is very standard functionality. For example, I used Elmah.MVC for this site. What I want to do is pretty much create a package that can be downloaded in a similar way to how we integrate Elmah.MVC into a site. (Be certain I'm not talking about creating error logging software, I'm only using Elmah.MVC as an example of software that is easily integrated into other website applications.)
I've never compiled any website functionality into a .dll(s) for use elsewhere and would appreciate either some specific guidance, or perhaps what would be easier is to provide a link with a good step by step tutorial or explanation for how to do this. Most of what I've found on the web describes bits and pieces of doing this, but it's not enough for me to feel confident with it.
It seems to me there are a lot of 'moving parts' to taking a particular piece of an MVC application and turning it into something that is easily added to other projects.
A particular issue I don't quite grasp is the difference in downloaded packages between getting code and getting just the .dll(s). For instance, when I download an MVC5 site, I get controllers, models and views, but when I download Elmah I get a .dll and no code files. Also, I do understand the concept of transforms, but I'm just struggling right now with even getting from my programmed application into a 'package' regardless of the transforms that make it easy to integrate into another website.
These are just some of my questions I have about how to perform this particular process in developing deliverable and/or shareable software.
What you are looking to do is create a portable MVC Area project. A Portable Area is a set of reusable multi page functionality can be dropped into an application to provide rich functionality without having to custom build functionality that is literally the same in every application. An MVC Portable Area is really just a dll that contains the views, controllers, scripts, etc… needed to use in a website that is either a Web Forms website or an MVC website. A developer can use them for a reusable widget or a complete engine. I have actually used them for both. Here is a link with some basic info to get started. http://elegantcode.com/2012/04/06/mvc-portable-areas/
What is the best language and approach to build the widgets website like http://www.pageflakes.com/. By best I mean rapid development, performance, smoothness and by approach I mean that some one will use drag and drop plug in jQuery (some issues) etc.
Two functionality will be main in my site:
selecting the widget and then dragging on the specified position i like
saving the state without login for the user.
You don't mention your existing language skills which might be the most important detail here. Also, are you prepared to learn a new language/framework for this project?
Some generic advice assuming you would be using Java: since the site in consideration looks more like a web application as opposed to a "web site", a framework which supports rich controls/Ajax natively might work wonders here. A GWT based framework like SmartGWT might be an interesting candidate.
I'm looking for a free, simple and efficient CMS for building website for a small company.
Prerequisites are:
The website is nothing more than a presentation - with informative content and gallery. The website should contain a nice-looking gallery with js/ajax flavour. Nothing more is planned for now, but it would be nice if CMS would feature some more generic modules/extensions in case I would like to use them in future.
Design templates should be easy to adopt and change.
Coding as little as possible.
I thought about Drupal, but is there any other CMS which would better fit to these requirements?
Please don't list available CMS-es here. Give it a reason!
Wordpress is nice too :p It has a big community behind...
I say Drupal.
Drupal is really good in content management. You can create different content types, and assign them fields (in Drupal 6, you will need the CCK contrib module). You can create a gallery with Views and it's output plugins. There are dozens of them, using different layout and JavaScript effects (mostly different jQuery plugins, but there are plugins for lightbox and thickbox also).
Drupal has a group of themes called "starter themes". These themes are half-ready, and it is very easy to create your own custom themes with them. All you need is to create a subtheme. (Basically making an info file and copy some other files. There are really a lot of howtos out there.) There are also starter themes for 960 (CSS framework), so you can make the site layout really fast. The most famous starter theme is called Zen. You might want to use that.
Except for the theme, I don't think that you have to write any code. Writing a theme for Drupal is not hard, since it uses PHP to render the themes.
Still in beta (0.5) phase but looking very promising: Orchard, a new ASP.NET MVC based CMS created by the people from Microsoft.
Orchard will create shared components for building ASP.NET applications and extensions, and specific applications that leverage these components to meet the needs of end-users, scripters, and developers. Additionally, we seek to create partnerships with existing application authors to help them achieve their goals. Orchard is delivered as part of the ASP.NET Open Source Gallery under the CodePlex Foundation. It is licensed under a New BSD license, which is approved by the OSI.
The intended output of the Orchard project is three-fold:
Individual .NET-based applications that appeal to end-users , scripters, and developers
A set of re-usable components that makes it easy to build such applications
A vibrant community to help define these applications and extensions
In the near term, the Orchard project is focused on delivering a .NET-based CMS application that will allow users to rapidly create content-driven Websites, and an extensibility framework that will allow developers and customizers to provide additional functionality through module extensions and themes.
It depends on what kind of CMS you are after
pity you don't like programming otherwise i would suggest django, an awsome CMS framework
if you are after something simple like a few static pages and a news feed or something like that then wordpress might suit your needs well, except i have found i don't like how it handles gallery's
if you need anything more, like more advanced custom content types for products, i would recommend Joomla or Drupal, and have plug-ins that has good support for photo galleys
Joomla! will probably be a better choice. It is very easy to use and is highly extensible.

If you have a little C# experience then you can try Umbraco.
It is a very powerfull CMS written in C# for ASP.NET
It is one of the most powerfull both free and commercial CMS out there.
i recommend to check out the Feature Matrix so you can see if it fulfills your needs.
As an example http://asp.net uses Umbraco
have you tried DotNetNuke ?
