Word suggestion java

We are given a Trie with a set of strings stored in it. Now the user types in a prefix of his search query, we need to give him all recommendations to auto-complete his query based on the strings stored in the Trie. We assume that the Trie stores past searches by the users. Prerequisite Trie Search and Insert. How can we improve this?

The number of matches might just be too large so we have to be selective while displaying them. We can restrict ourselves to display only the relevant results. By relevant, we can consider the past search history and show only the most searched matching strings as relevant results. Now when we want to show the recommendations, we display the top k matches with the highest hits.

Try to implement this on your own. This article is contributed by Hemang Sarkar. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

For example, if the user types "d", the textbox appears under the jtextfield with a suggested word like "dog" along with any other words that start with "d". So far, I think I need to create an array list of words to compare to what the user types and then maybe have a jcombobox positioned under the text field and set visibility to true when the user types.

What should I do? You can use jquery autocomplete.

Here is a example that helped me. Thanks Moh-Aw!!Have some basic understanding about — CDF and N — grams. Problem Statement — Given any input word and text file, predict the next n words that can occur after the input word in the text file. Note — For illustarting the example, I have assigned the variable corpus to some text.

If you want to test data on real world text data, you can find the data here. Solution — We can approach this problem using the concepts of probability.

Firstly we must calculate the frequency of all the words occurring just after the input in the text file n-grams, here it is 1-gram, because we always find the next 1 word in the whole data file. Then using those frequencies, calculate the CDF of all these words and just choose a random word from it.

To choose this random word, we take a random number and find the smallest CDF greater than or equal the random number. We do so because we want the most probable answer for each case. So that can be achieved by cdf as it gives the cumulative probability for each word in the list.

After finding the CDF, we can easily find the corresponding word and append that word to the output string. Now, if you wish, you can also append the word to the input string and send the whole string to repeat the process to find the next word, or you can just send the word that you found out using cdf. I have done that using the former approach.

Note — You will get a different output if you enter the same word multiple times. That depends on the size of your data file. Larger the file, more probability of a different output. The concept shown above is used in fields like Natural Langauage Processing. This is a naive approach just to illustrate the concept. Actually, there are much more algorithms out there for word prediction. You can find one of them here. Attention geek!

IntelliSense is a general term for various code editing features including: code completion, parameter info, quick info, and member lists. IntelliSense features are sometimes called by other names such as "code completion", "content assist", and "code hinting.

VS Code supports word based completions for any programming language but can also be configured to have richer IntelliSense by installing a language extension. Below are the most popular language extensions in the Marketplace. Click on an extension tile below to read the description and reviews to decide which extension is best for you. VS Code IntelliSense features are powered by a language service.

A language service provides intelligent code completions based on language semantics and an analysis of your source code. If a language service knows possible completions, the IntelliSense suggestions will pop up as you type. If you continue typing characters, the list of members variables, methods, etc.

Pressing Tab or Enter will insert the selected member. Tip: The suggestions widget supports CamelCase filtering, meaning you can type the letters which are upper cased in a method name to limit the suggestions.

For example, "cra" will quickly bring up "createApplication". If you prefer, you can turn off IntelliSense while you type. The accompanying documentation for the method will now expand to the side. The expanded documentation will stay so and will update as you navigate the list. When applicable, a language service will surface the underlying types in the quick info and method signatures. In the image above, you can see several any types. Because JavaScript is dynamic and doesn't need or enforce types, any suggests that the variable can be of any type.

The JavaScript code below illustrates IntelliSense completions. IntelliSense gives both inferred proposals and the global identifiers of the project.

The inferred symbols are presented first, followed by the global identifiers shown by the Word icon. VS Code IntelliSense offers different types of completions, including language server suggestions, snippets, and simple word based textual completions.

The settings shown below are the default settings. You can change these settings in your settings. The editor supports "tab completion" which inserts the best matching completion when pressing Tab.

This works regardless of the suggest widget showing or not. Also, pressing Tab after inserting a suggestions will insert the next best suggestion.
