Information Retrieval is simply a field concerned with organizing information. In other terms, IR is emphasizing the range of different materials that need to be searched. Others researcher said that IR is the contrast between the strong structure and typing a database system with the lack of structure in the objects typically searched in IR. The actual process in information retrieval systems is it has to deal with incomplete or under specified information in the form of the queries issued by users. IR uses the techniques of storing and recovering and often disseminating recorded data especially through the use of a computerized system.
IR systems receiving such queries need to fill in the gaps of the user’s underspecified query. For example, user typing “nuclear waste dumpling” into the search engine such as Google is probably searching for multiple number of documents that describing the topic. Some of the documents might not archive what user need as the search engine search documents that relate to the three worlds only. The content being searched is typically unstruc...
Databases always used to fascinate me from my under graduation with great curiosity to know how large data is managed and queried. This led me to do Masters in computer science concentrating in the field of Data Management. In the course of my study, I understood the concepts of DBMS which provides a robust and efficient way of managing and mining data. Through the courses like Database Systems (ITCS 6160), Knowledge Discovery in Databases(ITCS 6162) and Knowledge Based Systems(ITCS 6155) I gained enough theoretical and practical knowledge about the importance of proper organization of data, good techniques to build an efficient database management system and how well the data can be managed.
SEARCH-BASED APPLICATIONS: SBAs use semantic technologies to process and classify unstructured and structured content across multiple databases, and employ technologies for accessing information.
It is generally accepted that information is a vital commodity for the successful operation of today’s organizations. Nowadays modern business organizations are using computerized information systems in order to obtain such information. However as the technology advances rapidly the main issue is how can an organization should effectively use such an information system - which its management sometimes can be unpredictable - in order to effectively help the whole organization structure to improve and take the most out of it.
Most users will find what they are looking for the first times when conducting searches due to the database sufficiently being able to decode natural language. As users navigate through the website they will find many icons and tabs to help them through their searches. One does not have to be an expert to conduct searches using this database and will be able to use the simple search index to retrieve a desirable number of sources if the user knows exactly what they are trying to retrieve. This database would be an essential tool for students, teachers, or any patron to meet their informational
Information systems are a vital necessity to healthcare institutions in the United States and other nations with the ominous need to keep up with technology, research, and science in the 21st. Century. Most of healthcare institutions in Africa still depend on physical documentation, written by hand and afterword’s stored in binders locked away in storing facilities. With the growing populace in Africa, gathering information concerning patients health documents is costly, hard to maintain, and unethical. Therefore, in this case scenario I’m going to target my research, in developing countries in Africa in general, who are striving to improve ideal management information system. The goal is to aim efforts to improve public health through enhanced supervision through healthcare information, such the ability to collect, store and analyze accurate health data, service transfer proficiency, improve data accuracy, value of involvement, increase accountability and to learn about trends. The objective of this information system is to record information on health events and check the quality of services at different stages of health care. The data collected will also help to notify forthcoming healthcare policy determinations.
The vector space model is used to enhance search results by representing them as two vectors, the document vector and query vector. Each dimension in the vector corresponds to a different term. If the term occurs in the document, its value in the vector is a non-zero value. Several different ways of computing the term weights have been developed, one of which is the frequency-inverse document frequency (tf-idf) weights. The frequency portion of td-idf refers to the frequency of the term within the document.
In today’s fast paced technology, search engines have become vastly popular use for people’s daily routines. A search engine is an information retrieval system that allows someone to search the...
But, the drawback here is that the result size for each query is inconvenient to control and also, difficult to manage the volume of the search result and with that also to avoid excluding the relevant documents required for the search.
Database management system (DBMS) is a collection of interrelated data and a set of programs to access the data. The collection of data, usually referred to as a database, contains the information related to the Company, the company's system at workplace, detailed information as an example employee personal information stored in the data. The goal of a database management system is to provide a way how to store and retrieve data information more efficiently. For examples, of the data, consider the name, telephone number and address are known, the recorded data is indexed address book, can be stored on a floppy disk, using a personal computer and software such as dBase IV or V, Microsoft Access or Excel
An information retrieval system (IRS) is the activity of obtaining information resources relevant to an information need for a collection of information resources. Searches can be based on metadata or on full text (or content based) indexing. The automated information retrieval system is used to reduce what has been called “information overload”. Many universities and public libraries use information retrieval system to provide access to books, journals, and other documents. Web search engines are the most visible information retrieval application.
Information seeking is a fundamental human activity in the pattern of collecting information and satisfying the users’ information needs. Information seeking behavior (ISB) can be defined how a user proceeds in gathering information from the recognizing a lack of knowledge to fulfillment of understanding.

Web 3.0 also means that if the user was to search for something such as ‘man’ it would not just display results just for ‘man’ it will also know to display ...
Since the publication of the World Wide Web in 1991 people have been using search engines to obtain their information (Berners-Lee). These sources of information have greatly evolved over the past two decades and are continuing to become more efficient. Even though most any person with a computer uses a search engine, many do not know how it works. For starters, there are two main types of web searches: crawler based and human powered.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
