Image meta search (or image search engine) is a type of search engine specialised on finding pictures, images, animations etc. Like the text search, image search is an information retrieval system designed to help to find information on the Internet and it allows the user to look for images etc. using keywords or search phrases and to receive a set of thumbnail images, sorted by relevancy.
Specialized search engines, like in the fields of image search, are among the fastest growing search services on the internet. In 2005 alone the number of image searches increased by 91% (Nielsen/NetRatings 2006-03-31).
Many of the sites that today offer image search use a service powered by one of the big three; Google, Picsearch or Yahoo.

SEM Expert
Search engine marketing, or SEM, is a form of Internet marketing that seeks to promote websites by increasing their visibility in search engine result pages (SERPs) through the use of paid placement, contextual advertising, and paid inclusion.. The Pay Per Click (PPC) lead Search Engine Marketing Professional Organization (SEMPO), also includes search engine optimization (SEO) within its reporting, but SEO is a separate discipline with most sources, including the New York Times defining SEM as 'the practice of buying paid search listings'.
SEM Expert are those who excel in search engine marketing.
Vested interests appear to use the expression SEM to mean exclusively Pay per click advertising to the extent that the wider advertising and marketing community have accepted this narrow definition. Such usage excludes the wider search marketing community that is engaged in other forms of SEM such as Search Engine Optimization and Search Retargeting.

Content management
Content management practices and goals vary with mission. News organizations, e-commerce websites, and educational institutions all use content management, but in different ways. Content management, or CM, is a set of processes and technologies that support the evolutionary life cycle of digital information. This digital information is often referred to as content or, to be precise, digital content. Digital content may take the form of text, such as documents, multimedia files, such as audio or video files, or any other file type which follows a content lifecycle which requires management.
Content management is an inherently collaborative process. It often consists of the following basic roles and responsibilities:
Administrator - responsible for managing access permissions to folders and files, usually accomplished by assigning access rights to user groups or roles. Admins may also assist and support users in various ways.
Publisher - responsible for releasing the content for use.
Consumer, viewer or guest- the person who reads or otherwise takes in content after it is published or shared.
Editor - responsible for tuning the content message and the style of delivery, including translation and localization.
Creator - responsible for creating and editing content.

Crawling the Deep Web
A vast amount of Web pages lie in the deep or invisible Web. These pages are typically only accessible by submitting queries to a database, and regular crawlers are unable to find these pages if there are no links that point to them. Google’s Sitemap Protocol and mod oai (Nelson et al., 2005) are intended to allow discovery of these deep-Web resources.
Deep web crawling also multiplies the number of web links to be crawled. Some crawlers only take some of the

Information technology
Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.
Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases. A few of the duties that IT professionals perform may include data management, networking, engineering computer hardware, database and software design, as well as the management and administration of entire systems.
When computer and communications technologies are combined, the result is information technology, or "infotech". Information Technology (IT) is a general term that describes any technology that helps to produce, manipulate, store, communicate, and/or disseminate information. Presumably, when speaking of Information Technology (IT) as a whole, it is noted that the use of computers and information are associated.
