Why Use WordPress? What Can You Do With WordPress?

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?

WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:

1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.

2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.

3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.

4. Shortcodes
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.

5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.

6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.

FIBC/Jumbo Bags manufacturer & suppliers in India - Alpine FIBC Pvt Ltd

Bulk bags are a popular packaging solution for large quantities of products such as aggregates and waste. They have many names including, ton bags, garbage bags, FIBC, builders bags
The range of sizes and specifications of bulk bags is wide and each type will suit a different use. Specifications can also be quite detailed and technical, which can sometimes make it difficult to determine what type will be needed for the required use.
When deciding on the correct type of FIBC, the following points should be considered;

• Physical or chemical properties of the product intended to ent****er the bulk bag, such as:
  • Required volume
  • Weight of the product to contain
  • Bulk Density
  • Characteristics of the content flow
  • Degree of aeration.
  • Particle shape and size
  • filling temperature
  • If food grade is required
• FIBC filling, handling, transport, storage and emptying methods.
  See below for a complete summary of the terms of this popular packaging solution and their meaning. This will help make informed decisions about the type of bag needed.
  Terminology information
  IBC class = Single trip, reusable standard service or reusable heavy duty.
  Safe Working Load (SWL) = This is the capacity of the bag and is related to the maximum weight or volume of the product that the bulk bag can safely hold. Usually it will be displayed in kilograms and ranges from 250kg to 2000kg.
  Size = This will generally be displayed in external dimensions and in centimeters.
  Factor of Safety = Standard ton bags will have a factor of safety of 5: 1, which means a 1000kg capacity bag will not break, tear, or rip weighing less than 5000kg. A factor of safety of 6: 1 is a bulk bag made of thicker woven polypropylene fabric and tested to a higher standard, and is generally a heavy-duty or multi-ride FIBC.
  Filling and unloading functions
  Flat Base - This is a standard flat base on the bottom of the bulk bag that gives it a cube shape. All standard construction bags will come with a smooth base.
  Lifting Loops - Strong loops are sewn into each corner of the bag allowing a forklift to lift and handle it. All FIBCs will come with 4 lift loops.
  Fill Inlet: There are two types of fill inlets. They are;
  Filling nozzle: a long tube that allows contents to flow easily into the bag
  Skirt Top - Additional fabric on the top of the bag that can be secured around the filling device to prevent any loss of content, ensuring that all content flows easily to the IBC.
  Baffles = Additional inner baffles are inserted into the corners of the bulk bag. This can help stabilize the bag and make it stiffer and is used specifically for unstable or fluid products.
  Discharge nozzle = A tube made of woven polypropylene fabric is sewn into the bottom of the bulk bag. This provides easier flow of the content out of the bag when it is held on a hopper and the content is unloaded.
  Food grade = Food grade manufacturing relates to the conditions under which the FIBC has been manufactured and stored prior to delivery to the customer. These conditions are based on strict standards that allow the bag to be suitable for use in food. Food grade bulk bags generally come with an internal polyethylene lamination.
  There are two main types of food grade conditions;
  Clean room = Manufacturing / storage facilities are free of loose threads, dirt and dust. Usually best suited for poultry seeds and feed
  BRC Compliant Food Grade Bulk Bags = Manufactured and stored in strict BRC compliant conditions. This ensures that food grade fiber is suitable for packaging food ingredients without risk of contamination.
  Linings: An internal polyethylene liner provides additional protection for the interior content. Liner can be:
  • Loosely inserted or flanged
  • Handcuffed, where the lining is inserted and the top section is rolled over the top of the bag to make it more secure.
  • With tabs, the lining is sewn in place at the corners to ensure stability inside the bag.

Word Embeddings Versus Bag-of-Words: The Curious Case of Recommender Systems

Are word embeddings always the best choice?

If you can challenge a well-accepted view in data science with data, that’s pretty cool, right? After all, “in data we trust”, or so we profess! Word embeddings have caused a revolution in the world of natural language processing, as a result of which we are much closer to understanding the meaning and context of text and transcribed speech today. It is a world apart from the good old bag-of-words (BoW) models, which rely on frequencies of words under the unrealistic assumption that each word occurs independently of all others. The results have been nothing short of spectacular with word embeddings, which create a vector for every word. One of the oft used success stories of word embeddings involves subtracting the man vector from the king vector and adding the woman vector, which returns the queen vector:

Very smart indeed! However, I raise the question whether word embeddings should always be preferred to bag-of-words. In building a review-based recommender system, it dawned on me that while word embeddings are incredible, they may not be the most suitable technique for my purpose. As crazy as it may sound, I got better results with the BoW approach. In this article, I show that the uber-smart feature of word embeddings in being able to understand related words actually turns out to be a shortcoming in making better product recommendations.

Word embeddings in a jiffy

Simply stated, word embeddings consider each word in its context; for example, in the word2vec approach, a popular technique developed by Tomas Mikolov and colleagues at Google, for each word, we generate a vector of words with a large number of dimensions. Using neural networks, the vectors are created by predicting for each word what its neighboring words may be. Multiple Python libraries like spaCy and gensim have built-in word vectors; so, while word embeddings have been criticized in the past on grounds of complexity, we don’t have to write the code from scratch. Unless you want to dig into the math of one-hot-encoding, neural nets and complex stuff, using word vectors today is as simple as using BoW. After all, you don’t need to know the theory of internal combustion engines to drive a car!

Understanding Search Engine Filtering of Customer Reviews

In the digital era, you see people dropping reviews online as customers. We can even see companies seeking a platform to provide them with online reviews to boost their business. You might have heard or read about online review filters and how it might have caused frustrations or confusion. Understanding search engine filtering of customer reviews can help you minimize this vagueness.

Why do we need to filter reviews?

We can see an obvious sky-rocket in searching among people in the past decade. People depend on their search results and the reviews they read about a particular thing.

Reviews can be an excellent scale to measure the popularity of a business. It also gives real-life experience to searchers for a specific kind of business or service or etc.

If reviews are so cool and helpful, why do we need an algorithm to filter them?

Since the development of technology, you see that robots also can drop reviews. Some companies even hire people who even might not be customers to give them good reviews. We can also see companies dropping reviews for themselves. So, there you have the reasons for the filtering of customer reviews. For instance, on social media platforms, Instagram uses the filtering algorithm for cleaning the purchased followers.

How does the filtering work?

The specific details of these kinds of algorithms have not been revealed, but the general sense of the mechanism is out there, which is the backbone of most filtering algorithms. Filtering gets triggered when one or more of the following happens:

• Sudden increase in the number of reviews in a short period of time

• Abnormal usage of keywords

• Overuse of complimenting adjectives or swearwords

• Link usage in the reviews

Some of the more advanced and cutting-edge filters do not only stop at the aforementioned points. They also check the characteristics of users, such as:

• The IP addresses

• Number of reviews written by a single user on a website

• How often a user leaves reviews on a particular site

Considering the points above, one could understand how probable it is for the fake reviewers to get stuck in the filter, all thanks to the smart algorithm.
