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...
Users can be guided through each search method by using the Help option to find resources. Wildcard and Truncate search options are available for convenience if users are unsure of their search terms. However, like most search options the best way for a user to narrow in on a search is to use a Boolean statement. ProQuest offers many other options to help users export and save their searches for future use and for users to be a part of a network linking its users to computer systems
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.
Information Retrieval (IR) is to represent, retrieve from storage and organise the information. The information should be easily access. User will be more interested with easy access information. Information retrieval process is the skills of searching for documents, for information within documents and for metadata about documents, as well as that of searching relational databases and the World Wide Web. According to (Shing Ping Tucker, 2008), E-commerce is rapidly a growing segment in the internet.
SEARCH-BASED APPLICATIONS: SBAs use semantic technologies to process and classify unstructured and structured content across multiple databases, and employ technologies for accessing information.
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.
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.
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...
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.
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.

The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.

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.
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.
