The interface is similar to a class in Java, but it is a collection of abstract methods. A class can have more than one interface. A class is a blueprint for creating objects. A class contains methods and variables which are a class instance. The interface supports multiple inheritances. An abstract class would contain constructor. The interface does not contain a constructor.

    Deep learning is computer software that mimics the network of neurons in a brain. It is a subset of machine learning and is called deep learning because it makes use of deep neural networks. The basic OOPS principle are: 1 encapsulation, 2 abstraction, 3 inheritance and 4 polymorphism. The difference between compiler and interpreter is: Compiler Compiled code run faster. Interpreted code run slower. Generates output program in the form of exe , which can be run independently from the original program. Do not generate an output program. So the programmer evaluates the source program at every time during execution. The target program executes independently and does not require the compiler in the memory. The interpreter exists in the memory during interpretation. Difficult to implement as compilers cannot predict what happens at turn time. It is best suited for the program and development environment. It takes an entire program as an input.

    Closed-domain question answering deals with questions under a specific domain for example, medicine or automotive maintenance , and can exploit domain-specific knowledge frequently formalized in ontologies. Alternatively, closed-domain might refer to a situation where only a limited type of questions are accepted, such as questions asking for descriptive rather than procedural information. Question answering systems in the context of machine reading applications have also been constructed in the medical domain, for instance related to Alzheimer's disease. On the other hand, these systems usually have much more data available from which to extract the answer. Multimodal question answering uses multiple modalities of user input to answer questions, such as text and images. LUNAR, in turn, answered questions about the geological analysis of rocks returned by the Apollo moon missions.

    Both question answering systems were very effective in their chosen domains. Further restricted-domain question answering systems were developed in the following years. The common feature of all these systems is that they had a core database or knowledge system that was hand-written by experts of the chosen domain. It simulated the operation of a robot in a toy world the "blocks world" , and it offered the possibility of asking the robot questions about the state of the world.

  • Introduction

    Again, the strength of this system was the choice of a very specific domain and a very simple world with rules of physics that were easy to encode in a computer program. In the s, knowledge bases were developed that targeted narrower domains of knowledge. The question answering systems developed to interface with these expert systems produced more repeatable and valid responses to questions within an area of knowledge. These expert systems closely resembled modern question answering systems except in their internal architecture. Expert systems rely heavily on expert-constructed and organized knowledge bases , whereas many modern question answering systems rely on statistical processing of a large, unstructured, natural language text corpus. The s and s saw the development of comprehensive theories in computational linguistics , which led to the development of ambitious projects in text comprehension and question answering.

    Berkeley in the late s. The system answered questions pertaining to the Unix operating system. It had a comprehensive hand-crafted knowledge base of its domain, and it aimed at phrasing the answer to accommodate various types of users. Another project was LILOG, a text-understanding system that operated on the domain of tourism information in a German city. The systems developed in the UC and LILOG projects never went past the stage of simple demonstrations, but they helped the development of theories on computational linguistics and reasoning. Specialized natural language question answering systems have been developed, such as EAGLi for health and life scientists.

    Architecture[ edit ] As of , question answering systems typically included a question classifier module that determines the type of question and the type of answer. It thus makes sense that larger collection sizes generally lend well to better question answering performance, unless the question domain is orthogonal to the collection. The notion of data redundancy in massive collections, such as the web, means that nuggets of information are likely to be phrased in many different ways in differing contexts and documents, [9] leading to two benefits: By having the right information appear in many forms, the burden on the question answering system to perform complex NLP techniques to understand the text is lessened. Correct answers can be filtered from false positives by relying on the correct answer to appear more times in the documents than instances of incorrect ones. Some question answering systems rely heavily on automated reasoning. Open domain question answering[ edit ] This section needs additional citations for verification.

January Learn how and when to remove this template message In information retrieval , an open domain question answering system aims at returning an answer in response to the user's question. The returned answer is in the form of short texts rather than a list of relevant documents. The system takes a natural language question as an input rather than a set of keywords, for example, "When is the national day of China?

  • Computer Science Interview Questions

    Having the input in the form of a natural language question makes the system more user-friendly, but harder to implement, as there are various question types and the system will have to identify the correct one in order to give a sensible answer. Assigning a question type to the question is a crucial task, the entire answer extraction process relies on finding the correct question type and hence the correct answer type. Keyword extraction is the first step for identifying the input question type. In the example above, the word "When" indicates that the answer should be of type "Date". POS part-of-speech tagging and syntactic parsing techniques can also be used to determine the answer type.

    In this case, the subject is "Chinese National Day", the predicate is "is" and the adverbial modifier is "when", therefore the answer type is "Date". Unfortunately, some interrogative words like "Which", "What" or "How" do not give clear answer types. Each of these words can represent more than one type. In situations like this, other words in the question need to be considered. First thing to do is to find the words that can indicate the meaning of the question. A lexical dictionary such as WordNet can then be used for understanding the context. Once the question type has been identified, an information retrieval system is used to find a set of documents containing the correct keywords.

    For questions such as "Who" or "Where", a named-entity recogniser is used to find relevant "Person" and "Location" names from the retrieved documents. Only the relevant paragraphs are selected for ranking. A vector space model can be used as a strategy for classifying the candidate answers. Check if the answer is of the correct type as determined in the question type analysis stage. An inference technique can also be used to validate the candidate answers. A score is then given to each of these candidates according to the number of question words it contains and how close these words are to the candidate, the more and the closer the better. The answer is then translated into a compact and meaningful representation by parsing. In the previous example, the expected output answer is "1st Oct. The resulting formula is translated into a computable form, allowing the user to insert values for the variables.
