In context of our country, there are many people who are facing problems in English languages due to various reasons. So there are various English- Nepali dictionaries available in the market today. Such dictionaries come under the category of Bilingual dictionaries 1. These types of dictionaries can be of two types unidirectional and bidirectional.

Unidirectional dictionaries provide only one way meaning searching whereas the bidirectional can do in the both way. Our application is based on the learning approaches which is a major component of the AI of the computer science field. Before describing learning, let us briefly know about artificial intelligence and its other factors. It is also popularly called robitics as such agents are normally called robots also. Intelligent Agents: Intelligent agents are the devices or any sofwares that perfoms the tasks automatically with some facts given in them.

An agent generally recieves the outer environment though its sensors and show its action to the environment through its actuators. The matching also called the rule firing is done by matching the input with the knowledge and firing the actual rule. Intelligent agents acquire and store facts into its knowledge base by means of learning. Learning are also categorised in two categories. The training data consist of a set of training examples.

In supervised learning, each example is a pair consisting of an input object typically a vector and a desired output value also called the supervisory signal. A supervised learning algorithm analyzes the training data and produces an inferred function, which can be used for mapping new examples.

Unsupervised Learning: Unsupervised learning is the problem of finding the hidden structure in unlabeled data. In this type of learning, since the data given to the learner are unlabeled, there is no reward or error signal to evaluate a potential solution.

We are now concerned with development of English- Nepali bilingual dictionary. This project comes under the supervised learning of artificial intelligence beceause we have the knowledge base stored in the memory of the agent i. But they are of other languages and there are rare for our language.

The dictionaries currently available use a database containing meaning of the English word for the given language of the dictionaries. Such dictionaries are limited to certain thousands of the words and needs to be updated with the addition of the words in it.

So to overcome the problems created by the traditional dictionaries, a new concept has been arised. The concept is the corpus based dictionary. Before actually diving through the corpus based dictionaries lets us know some terms used in this type of dictionary. Such texts are also used used for checking 10 occurances and validating the rules within a specific language or territory.

The corpora may contain the structured text in a single language which is known as the Monolingual corpora and also might have been formated or devleoped for the side by side comparison of two languages. Such corpus contains the text in two languages and is termed as multilingual corpus.

Such dictionaries are used mainly to translate words from one language to another language. Like English to Nepali or any other two languages.

In corpus based dictionary, the corpus files are downloaded and are parsed and a database of the words and meanings is created and user searches the meaning in the database for both game and search in our app. The tradiotional dictionaries are limited to certain thousands of words and needs updatings with the increase of the words. But in case of corpus based dictionaries the addition of words and meanings is easy and need not update in the application or system built with increase of the words.

Another interesting advantage in our view in CBD than normal dictionries is the multilingual expansibility.

Apart from this the application has the following objectives. User friendly UI: - All the application for any plateform will be finally used by the user. The user may feel tedious or boring if the UI of the application is not good and properly managed.

So in Learning Dictionary, we have tried to use the user friendly UI as far as possible. It will help the user to use the application efficiently. It also 11 had been made supportable to coming up versions of Android like Kitkat and LemonPie.

It can be useful to the language learners to learn Nepali with the English language. The major limitation of this application is the size of the SD Card that the user is using. Another limitation of the application is the Android lower versions like Cupcake and Donnut since the application is target of the application is from Android Eclair.

Currently this application cannot display the parts of speech of the words you are searching. This application can currently show only the Nepali meaning of the words you entered in English. It also focuses on the specification of the software boundaries. Requirement analysis is to clearly distinguish new functionalities from existing ones supported by the current running system, and a clear distinction has to be done between their functionalities.

It is used by analysts to help identify business problems and propose solutions. It is a process that produces a set of requirements that, when realized, will satisfy an expressed need. It is a way of converting raw customer requirements into well-formed and organized ones.

System requirement specification does not result in a set of instructions. We use it to ensure communication between the technical community and agreement on what the system must do to achieve its goals.

During design and development, we use it to determine the requirements of the various parts we determine the system must have. We use it to develop test plans. We use it to verify the system operation when we believe we are done.

A function is described as a set of inputs, the behavior, and outputs. Nonfunctional requirements are difficult test; therefore, they are usually evaluated subjectively. Application must be updatable based on the arrival of new words.

Feasibility analysis of Learning Dictionary: 14 Learning Dictionary is the android based application that simplifies user to search the meaning of the words in Nepali from the English language.

The following are feasibility analysis of the application. The technical requirements of the application to run are as follows: The system required android based plateform to operate. During the development of the application, the minimum SDK level of the application is set to 7 so it can operate from Android 2. It is operatable on the androids latest version ie. Economical feasibility: Generally it may be expensive or rare to find the English to Nepali dictionary in the market. Though we may find it, it may not give the new words i.

So it might be difficult and expensive to download each new version of the dictionary with new words. Taking this in mind, we have come to develop this application, which can provide the frequent update of the new words in the application from the online stored corpus. So it might be easy and economically feasible to the user of these application than to download the new edition of the paper dictionary for each of some thousand new words. Operational feasibility: This application is operated on the android plateform.

The application will have two files i. The application contains update vocabulary method. The method will parse the. It uses Java as the programming language for the activities of the application. Such activities are coded as java classes. The application also contains other helper class for defining the SQlite database and for other purposes. The arrangement of all the classes can be diagramatically presented as the below class diagram. The mobile operating system is the software platform on top of which other programs, called application programs, can run on mobile devices.

Originally released in for the iPhone. Apple update and test various version of IOS for iPhone, they focus on different types of mobile application for iPhone user. Latest version of IOS is 7. Unlike Windows Mobile, Windows Phone 7 also referred to as WinPho7 is targeted more to the consumer market than the enterprise market, and it replaces the more traditional Microsoft Windows OS. The latest release is Windows Phone 8, which was launched on October 29, With Windows Phone, Microsoft created a new user interface.

It was initially developed by Android, Inc, which Google backed financially and later bought in Android is open source, This open-source code and permissive licensing allows the software to be freely modified and distributed by device manufacturers, Android has recently introduce Android 4.

Which Google backed financially and later bought in Android is open source, This open-source code and permissive licensing allows the software to be freely modified and distributed by device manufacturers. Android has a large community of developers writing applications "apps" that extend the functionality of devices, written primarily in the Java programming language.

In October , there were approximately , apps available for Android, and the estimated number of applications downloaded from Google Play, Android's primary app store, was 25 billion. Android provided various version of OS for mobile application user they are following 4. The Android 1. There were plenty of changes behind the scenes, too.

Cupcake brought features like improved Bluetooth support, camcorder functions, and new upload services like YouTube and Picasa. While not very rich in the eye-candy department, Android 1.

To the end user, the two biggest changes would have to be the improvements to the Android Market, and universal search. Behind the screen, Donut brought support for higher resolution touchscreens, much improved camera and gallery support, and perhaps most importantly, native support for Sprint and Verizon phones.

Without the technology in Android 1. The devices released with Android 1. Introduced in late , Android 2. Google Maps Navigation also was born in Android 2. And to date, the Droid remains the phone phone to have explicitly received Android 2. The now-defunct Google Nexus One was the first device to receive Android 2.

From there, the rollout of Android 2. Manufacturers skipped Android 2. The single largest change was the introduction of the Just-In-Time Compiler -- or JIT -- whichsignificantly speeds up the phone's processing power. Along with the JIT, Android 2. That means you can play your favorite Flash-based games in Android's web browser. Take that, iPhone! Froyo also brought native support for tethering, meaning you could use your Android smartphone's data connection to provide Internet wirelessly or with a USB cable to just about any device you want.

Sadly, most carriers will strip this native support in exchange for some sort of feature they can charge for. Can't really blame them, can you? Gingerbread brings a few UI enhancements to Android, things like a more consistent feel across menus and dialogs, and a new black notification bar, but still looks and feels like the Android we're used to, with the addition of a slew of new language support.

Gingerbread brings support for new technology as well. Further optimizations for better battery life round out a nice upgrade. Behind the scenes, the fellows at Mountain View spent time with more JIT the Just-In-Time compiler optimizations, and made great improvements to Androids garbage collection, which should stop any stuttering and improve UI smoothness.

Round that out with new a multi-media framework for better support of sound and video files. X - Honeycomb Android 3. It's the first version of Android specifically made for tablets, and brings a lot of new UI elements to the tablet. Things like a new System bar at the bottom of the screen to replace the Status bar we see on phones, and a new recent applications button are a great addition for the screen real estate offered by Android tablets.

Some of the standard Google applications have also been updated for use with Honeycomb, including the Gmail app and the Talk app. Both make great use of fragments, and the Talk app has video chat and calling support built in. Under the hood, 3D rendering and hardware acceleration have been greatly improved. We can't talk about Honeycomb without mentioning that it also shows Google's new distribution method, where manufacturers are given the source code and license to use it only after their hardware choices have been approved by Google.

This dampens third party development, as the source code is no longer available for all to download and build, but Google assures us they will address this issue in the future. Dubbed Ice Cream Sandwich and finally designated Android 4. Later in the year, the release of the Nexus 10 andNexus 4 updated things 21 from 4. The release polished the UI designstarted in Ice Cream Sandwich, and brought several great new features to the table.

Besides the new focus on responsiveness with Project Butter, Jelly Bean brings multi-user accounts, actionable notifications, lock screen widgets, quick-settings in the notification bar, Photosphere to the "stock" Android camera and Google Now. Jelly Bean is hailed by many as the turning point for Android, where all the great services and customization options finally meet great design guidelines. It's certainly very visually pleasing, and we'd argue that it's become one of the nicest looking mobile operating systems available.

We're not yet sure what manner of goodies we'll find in the next version of Andorid, because Google has been understandably cryptic with details. Their US partner in the deal, Hershy, hasn't been so quiet.

They promise an update that really does taste as good as it looks, and offers adjustable orientation that works perfectly in portrait or landscape. If you enjoy a little tongue-in-cheek humor, have a look here and speculate with everyone else. In todays practice, the work of making a device follow our command is generally done by building applications or operating systems that run on the devices.

Developing an operating system is considered to be a difficult task and is done by some companies like Microsft, Apple and Google.

So what we mean here is developing an application on the OS developed by those companies is known as programming or developing also called app development. Though there are a lot of plateforms to work on, we have choosen android development in this project because we are gaining knowledge on exciting use of XML and java language in hand held device programming.

Here we want to mention a little on various components in android programming. While developing an application in android plateform, we need to be fimiliar with some terminologies.

These terms are used in another plateforms of programming as well which are; SDK Software Development Kit : It is the basic set of tools that allows the creation of application for a certain package, software framework or hardware platerform, computer systems or any other such development packages. This is a general development tool for all the developing plateform.
