Minimal Deterministic Finite Automaton

How to Add Facebook Style Autocomplete for WordPress Posts

Prefix trees handle common prefixes efficiently, but other shared word parts are still stored separately in each branch. For example, suffixes, such as -ing and -ion, are common in the English language. Luckily, there is a way to store shared word parts more economically.

A prefix tree is an instance of a class of more general data structures called acyclic deterministic finite automata . There are well-established algorithms for transforming a DFA into an equivalent DFA that has as few nodes as possible.

The minimal DFA for words need, nested, seed and speed consists of only 9 nodes compared to 17 nodes in the original prefix tree in the previous picture.

Minimizing a prefix tree DFA reduces the size of the data structure. A minimal DFA typically fits in the memory even when the vocabulary is large. Avoiding expensive disk accesses is key to a lightning fast autocomplete.

Additional Code And Resources

I used a MySql database containing a table listing each of the recipient names, and the following PHP file to accept the data sent by the getJSON method and pull matching recipients from the database:

< ?php//connection information$host = "localhost" $user = "root" $password = "your_mysql_password_here" $database = "test" $param = $_GET //make connection$server = mysql_connect $connection = mysql_select_db //query the database$query = mysql_query //build array of resultsfor   $x <  $numrows  $x++) //echo JSON to page$response = $_GET . " . ")" echo $response mysql_close ?> 

To run the downloadable example files, you’ll need a development web server with PHP installed and configured, as well as MySql and the appropriate database and table. When a letter is typed into the ‘to’ field, this letter is passed to the server and used to pull out each name that begins with the letter that was typed. The matching names are then passed back to the page as JSON and displayed in the suggestion menu:

The recipients would need to have some kind of meaning to back-end system of course, and would probably be mapped to email addresses in the database. We’d need to retrieve the textual content of each of the < span> elements before passing back to the server, although this would be a fairly trivial matter.

How To Change The Limit For The Autocomplete List

Because this configuration is untested, we don’t recommend it. If you have a larger AutoComplete list, you could also lose a larger number of cached entries if your AutoComplete cache becomes unusable because of corruption. Given this disclaimer, you can use the following registry data to increase the AutoComplete list limit in Outlook.


This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry,see How to back up and restore the registry in Windows.

  • Adding A Query Suggestions Database

    Facebook Now Testing

    This code has the same finite dataset of terms we used previously. Were still prototyping. Youll need to connect your back-end API to a database. The query delay will become even more important when each call includes a round trip HTTP call, which itself calls a database.

    The benefit is clear, though: by accessing a database, you can suggest a robust set of query suggestions that match the users characters as they type. A query suggestions database contains prior queries saved by the search engine as it processes every query. These queries are usually ranked by popularity. Google provides an example of this:

    Theres a lot to consider for your database. Is it especially built for search terms? Or do you need to connect to an existing source, such as a product or content database? And how will you tune it to these frequent, short queries?

    These are big questions that will likely point to a need to pull results from multiple sources, a concept called federated search.

    Data Structures For Fast Autocomplete

    Autocomplete is a feature that suggests a complete word or phrase after a user has typed just a few letters. The feature increases text input speed especially on mobile devices, because one doesn’t have to type every letter in a word. Autocomplete functionality is commonly found on search engines and messaging apps.

    A good autocompleter must be fast and update the list of suggestions immediately after the user types the next letter. This blog post studies algorithms and data structures that are necessary for attaining a satisfactory speed.

    Antti Ajanki

    Lead Data Scientist

    An autocompleter can only suggest words that it knows about. The suggested words come from a predefined vocabulary, for example all distinct words in Wikipedia or in the Oxford English Dictionary. The number of words in the vocabulary can be large: Wikipedia contains millions of distinct words. The vocabulary grows even larger if the autocompleter is required to recognize multi-word phrases and entity names.

    The heart of an autocompleter is a function that takes in the beginning of a word, or a prefix, and searches for vocabulary words that start with the given prefix. Typically, only a small number of possible completions are returned. There are many ways to implement such a function. Let’s take a look at a few of the possibilities. We start from a straightforward but slow implementation and build progressively more efficient methods on top of that.

    The Chatbot Breaking Sex

    Im always intrigued to see brands utilizing chatbots in new and interesting ways. However, I find it even more inspiring when the technology is used for social good. Planned Parenthoods new bot, Roo, is an amazing case study in how chatbots can provide the perfect solution to increasingly difficult challenges. The challenge:

    • Issues with the administration of sex education in the US means that 84% of teens turn to the internet for help.
    • It can be hard to know what information to trust online.
    • Gen-Z are very wary of their privacy online and their digital footprint, particularly when it comes to more sensitive subjects.

    The solution:

    Roo provides answers to any questions a user may have about sexual health all while providing them with complete anonymity.

    • Roo uses Natural Language Processing to anticipate the question and also anticipate the sentiment of the question to be able to answer it.
    • A content strategist has crafted the responses to ensure theyre suitable in voice and tone.
    • Educators have reviewed the content to approved its medically accurate and up to date.

    If you want to know more about Roo, theres a great article over on Recode and a podcast with the bots creator. Alternatively, you can revisit your awkward teenage years and ask Roo a question yourself.

    And thats it for another couple of weeks. As usual, you can carry on the conversation at

    How Does This Help

    One method suggested as part of this SC is to use the HTML 5.2 autocomplete attribute with appropriate tokens. This helps the browsers to store very specific personal data and fill them as appropriate. Further, for people who find difficult to understand words, an assistive technology can add a personalized symbol after identifying the programmatically determinable purpose of the input fields. For example, a birthday cake picture can be added close to the field that asks for date of birth so that the users can fill their date of birth.

    Facebook Begins Roll Out Of Facebook Pay

    Android Phone : How to Clear Autofill data on Facebook App

    One thing is for certain, Facebook is serious about its consumer payment and finance aspirations. While theyre ploughing on with plans to launch their blockchain-based cryptocurrency Libra in 2020, just last week they began .

    While making payments on Facebook is nothing new, Facebook Pay streamlines the process by allowing users to save their preferred payment method instead of having to re-enter their information every time.

    At the moment, Facebook Pay is limited to users in the US for fundraisers, in-game purchases, event tickets, person-to-person payments on Messenger and purchases from select Pages and businesses on Facebook Marketplace.

    However, I think its only a matter of time before businesses will be able to utilize Facebook Pay within Messenger. It will also fit seamlessly with Instagram Shopping and the newly launched WhatsApp Catalogs, providing consumers with a range of complete shopping experiences contained within messaging apps.

    Currently, the world of e-commerce UX is synonymous with websites but this new development is a huge opportunity for brands to leverage exciting new revenue streams.

    What Are The Google Autocomplete Guidelines

    Not all search queries are deemed appropriate to display as predictions.

    These types of predictions go against :

    • Violence and gore
    • Sexually explicit, vulgar, or profane language, though medical and scientific terms are allowed
    • Anything related to hate speech or approval of hateful acts
    • Sensitive information or terms about named individuals
    • Dangerous predictions, meaning searches for things that could allow serious harm to people or animals to happen

    Google admits that while they do their best to remove inappropriate predictions, they dont always get it right, so they provide a way to report a prediction.

    How To Implement Autocomplete With Javascript On Your Website

    Youve likely seen autocomplete searches before, where users get suggested searches as they type. Not only does it save keystrokes and time for your users, it can also uncover potential results they might not have found otherwise.

    For example, if someone types apple into your product catalog search, theyll get various suggestions as they type. To provide matches, youll need to pull these potential results from somewhere a database, an API, or a list of known terms.

    Before going down the rabbit hole into building your own autocomplete, lets take a look at a robust, production-level solution:

    Weve written about this autocomplete solution, which can transform the simple drop down into a rich and multi-faceted interactive user experience. When todays users start typing a query, they expect to see more than just suggested queries they want access to a variety of datasources and results, multiple filters, categories, and images with helpful and highlighted text.

    This autocomplete library is open sourced and fully customizable for any industry and UI/UX design.

    In this article, we take a step back and show you how to build a simple autocomplete with Javascript, to help you understand the principles of our more production-level version. Well also show that to tune your autocomplete search correctly, youll need to work with additional front-end and back-end code that does the heavy lifting for you.

    Federated Search: Query Multiple Dynamic Data Sources

    Most search engines youve used are likely pulling from more than one database. Unlike the basic autocomplete example, they dont have the benefit of a small, static set of potential searches. If youre concerned about the performance impact on a single database, its even more difficult with federated search.

    Not only do you have multiple sources, but each is dynamic. The products database may update nightly, while the inventory management system aims to be real-time. Your reviews are likely stored elsewhere and published several times per day. You may want comments to be available more quickly to generate discussion.

    Each of these databases has fields you probably want searchable and others you dont. Product names, descriptions, and metadata clearly need to be included. But internal identifiers or product codes might not be necessary. Similarly, user-generated content can provide rich search terms, but youll want to make sure personal information like email or IP addresses are kept from the search suggestions.

    The left image shows how your front end calls a back-end API that itself makes multiple requests to your databases. It would need to merge and filter these responses into a single set of search suggestions or results for the front end to display.

    There are many different approaches to how you merge and filter federated search results. To provide the best user experience for searchers, you may want to consider some additional ways to tune your results.

    How To Use The Jquery Ui Autocomplete Widget

    In this tutorial we’ll be looking at one of jQuery UI 1.8’s newest components – the Autocomplete widget. Auto-completing text fields can be a popular choice with visitors to your site because they make entering information much easier. They can be used on product search fields for example, or when a visitor must enter a country, or a city, or anything else that may be a choice from a common dataset. As well as being popular with visitors, the jQuery UI Autocomplete is popular with developers because it’s easy to use, powerful and flexible.

    I’m not a massive fan of Facebook, I much prefer Twitter , but one Facebook feature I do like is the messaging feature which lets you send a message to a friend or friends. I like how the autocomplete is used to make selecting your friend’s names easier, and how the names are formatted once they have been selected and added to the ‘to’ field, e.g. they each have a close link in them that allows the name to be easily removed without having to select any text.

    In this tutorial we’ll use the jQuery UI Autocomplete widget to replicate this aspect of Facebook’s messaging system. We won’t be looking at actually sending messages however. This is what we’re going to create:

    Basic Implementation Using Static Data

    To start, lets create a proof of concept autocomplete example. Our goal is to allow the user to start typing into a search box and see matching terms below the search form autocompleting the users input as its typed into a search bar.

    Any JavaScript autocomplete search is going to need the following:

    • HTML for the search form
    • CSS to display the results
    • A data source of results
    • JavaScript, of course

    Since were starting with a basic implementation, well return exact match results from a set of predetermined search terms. Well use an online store as our example, where the user is searching for a specific item. If what they have typed in the search box can be completed to match an item, the website suggests that item.

    Lets see how that search box looks in some simple HTML:

    123 < form autocomplete=”off”> < input type=”text”name=”q”id=”q”< span style=”font-weight: 400 “> onKeyUp< /span> =”showResults” /> < div id=”result”> < /div> < /form>

    Disabling autocomplete might seem a little strange, but this needs to be done to disable the browsers automatic suggestions, which will get in the way of our own.

    A couple of other things to note are the onKeyUp attribute, which calls our JavaScript function, and uses an empty div for results.

    Next, heres the JavaScript to receive the search value, match it against the known terms, and display suggestions:

    1 res.innerHTML='< ul> ‘+list+'< /ul> ‘ }

    A little CSS can complete the style, which you can customize to match your site:

    1 background:#eee }
