Introduction • Content management • Referred as content management system (CMS) • System used to manage the content of a web site • Personalization • Software system that allows an internet site to provide the user with a web page the reflects the interest, needs, and action of the users
Portals:The Basics • Portal • A web page that offers links to other websites • Can be broad or narrow • Does the portal provide a wide range of resources or a specific set of materials? • For example, while some portals archive information on every subject area in all formats, others focus on a specific content area or type of resource such as science videos, historical information, or lesson plans • Specific or general
What is a Portal • A portal is - a web site (Internet, www, html on TC/IP) - an entry point to other web resources - virtual workplaces where enterprises meet… • employees (B2E portals: intranet/extranet) • customers & providers (B2C, B2B) • vertical portals (vortals) • enterprise portals (EP) • corporate portals (CP) • They can be all these things together!
Portals • Some sites that started as search engine sites grew into portals • Portals offer a variety of other services including email and chats • Portals are also “doorways” to other Web sites • Unlike ISPs, portals do not provided connections to the Internet
Portals:The Basics Portals are considered to be virtual workplaces that: • Promote knowledge sharing among different categories of end users • Provide access to stored structured data • Data warehousing, database, transactional systems • Organize unstructured data • Electronic documents, lessoned learned
The Basics (cont’d) Portals are tools that could ( adv ): • Simplify access to data stored in various application systems • Facilitate collaboration among employees • Assist the company in reaching its customers
The Basics (cont’d) Web portals • Allow producers and users of knowledge to interact • Web portals provide two kinds of interfaces: • The knowledge producer interface • The knowledge consumer interface
The Basics (cont’d) Portal disadvantages • Difficulty integrating with other applications • The need for additional investment in technology • The difficulty of retaining skilled staff
EVOLUTION OF PORTALS • According to subject Portal can be • Horizontal Portal • Electronic exchange that focuses on many subject ( yahoo, MSN) • Focus on many subjects (public portal) • Categorize personal interest into group • Vertical Portal • Focus on specific subjects (webMD)
EVOLUTION OF PORTALS • Also Portal can be • Internet public portal • Enterprise Portal • Belongs to a specific company and organization • Deals with information with this company
EVOLUTION OF PORTALS • Search engines • Employ simple search technology for locating information on the web • Navigation sites • Search engine • Categorize personal interest into group (news, sport,…) • Portals evolved to include advanced search capabilities and taxonomies
EVOLUTION OF PORTALS • Enterprise Information Portals are tools that should: • associated with large organizations • Simplify access to data stored in various application systems • Facilitate collaboration among employees • Assist the company in reaching its customers
Knowledge Portal • A webpage or a facility that offers a single , uniform point from which all of an enterprises data sources can be accessed • Less on information content • More on improving knowledge worker productivity • Provide verity of information on various topics and can be customized to meet user individual needs on line
Knowledge Portal • Two Type of interface • The knowledge producer interface • Allows the knowledge worker to gather, analyze, and collaborate with peers to generate new knowledge • The knowledge consumer interface • Customization
Enterprise Knowledge Portal • Distinguish knowledge from information’ • Provide facility for producing Knowledge from data and information • Provide basis for making decisions
Information & Knowledge Data processing Information inferring Knowledge
Knowledge Portals Versus Information Portals Enterprise Information Portals • Use both “push” and “pull” technologies to transmit information to users through a standardized Web-based interface • Integrate disparate applications into a single system • Have the ability to access both external and internal sources of data Enterprise Web Portals • Are goal-directed toward knowledge production, knowledge acquisition, knowledge transmission, and knowledge management • Are focused on enterprise businessprocesses • Provide, produce, and manage information about the validity of the information they supply • Include all EIPsfunctionalities
Key characteristics • User-customizable message on the web page • Directory search • Knowledge channels • Powerful search engine • Acquisition Knowledge center • Officer career announcement • Calendar and FAQs
A Portal has a number of keycomponents • Registration • The ability for a user to sign onto the portal and have the ability to access all resources from one login • Searching • The ability to traverse internal and external data sources and present back to the user a simple view of findings • Personalization • The ability for the user to manage the layout of the desktop and to provide a profile to contain areas of interest • Alerting • The ability to integrate with common services (e.g. e-mail) to notify the user of immediate changes and actions • Content Management • The ability to manage content directly on the portal • Integration • The ability to connect to legacy and enterprise applications
Summary • Many websites are not portals themselves, but often become an element of a portal. • a major starting point for web users • portals are defined as "user-driven" and "customizable" interfaces to web resources • Some people refer to their favorite portal as their home on the web
Search Engines • Software agent whose task is to find information by looking at keywords or by following a certain guidelines or rules
Search Engines • Search engines are vary in • Database size • Navigation format • Collection methods
Search Engines • Engines can collect website data by employing • Crawler • Human editor • Paid subscriber
Search Engines • Crawlers • Computer automated program that search the internet for web links • Links added to DB and categorized by keyword and relevancy for future • Human editor • Employ web surfing to find links to added to DB • But it categorized by human analysis • Paid subscriber • Add web site to their DB with understanding that he will paid for each Website
Search Engines • Most important attributes in the success of Search engine is a way of ranking pages • Is the algorithm assumes that the more links a page has the better it is • The search is determined by • Content ( keyword) • Links ( ranking)
Business Challenges • To optimize the performance of operational processes in order to reduce costs and enhance quality • Companies need to commercialize their products at the lowest price possible
Portals and Business Transformation • The explosion of key business information captured in electronic documents • Many organization losing grip on information as they transform into new system and process upgrade • The speed by which the quantity and kinds of content is growing
Portals and Business Transformation • Challenges (Organization): • Shorter time to market • Knowledge worker turnover • Organization that do not tap into their employee mind and take advantage of the knowledge within will fall behind quickly • More demanding customers and investors
Market Potential • Knowledge portal is a key tool for supporting the knowledge workplace • 85% of organization plan to invest in portal during next 5 years • Portal can provide easier, unified access to business information and better communication among customer and employee

Web Portals Components • Content management • Business intelligence • Data warehouses and data mining • Data management
Web Portal Technologies • Main goal of a portal is to provide a single point of access to all information sources • portal must contain the following functionality • Gathering • Categorization • Distribution • Collaboration • Publish • Personalization • Search/navigate
Web Portal Technologies • Gathering • Documents created by knowledge workers are stored in variety of location( files, database, …) • Data and document needed to be captured in a common repository
Capture & Gather • Documents are typically written in multiple formats and stored in multiple places. • E.g.: • file systems on individual workstations • file systems on intranet servers • web sites (http servers) • file repositories (ftp servers) • Other DM Systems (like Lotus Notes) • So they need to be collected, hence standardized, and registered to be further manage
Capture & Gather • The process of capturing a document is called Crawling and it is often performed by “simple” softbots (software robots) or agents. • They start from a given URL (Uniform Resource Locator), i.e. a specific document – and recursively follow all the links in each document. • At this step the system must cope with access and security issues (broken links, restricted area, crypted sources, etc..).
Capture & Gather • Gathering requires a first-level analysis. This is performed by a content analyzer. Its task is to extract data and meta-data and put them in a standard format (like XML). • Multiple-formats issues are coped with. • Data is intrinsic at the document (ie the textual content); meta-data (creation date, author, confidentiality, etc..) is an extrinsic feature.
Web Portal Technologies • Categorization • Organize information on the repository in meaningful ways for navigation and searching • Portal should support categorization at all levels ( customer , employee,…) and in various dimension ( process, product,..)
Web Portal Technologies • Distribution • Portal should help individuals acquire knowledge • Through active ( search ) or passive (push) mechanisms • Support distribution of structured and unstructured information
Web Portal Technologies • Collaboration • Achieve through messaging, work flow, discussion DB • This functionality expands the role of portal from passive information provider to an interface for all types of an organizational interface
Web Portal Technologies • Publish • Publish information to all types of users • Personalization • Necessary for successful portal • Allow individuals to enhance their productivity • Search/navigate • Provides tools for identifying and accessing specific information
Collaborations • Is a fundamental starting point for e-business transformation • goal is to support information sharing
Types of Collaborations • Asynchronous collaboration • is human-to-human interactions via computer • sub-systems having no time or space constraints. • Queries, responses, or access occur anytime and anyplace • Synchronous collaboration • is computer-based, human-to-human interaction that occurs immediately (within 5 seconds). • It can use audio, video, or data technologies
Requirements for successful collaborations tools • E-mail system that support collaborative services (shared calendars, task lists,..) • Web browser for browsing and presenting the documents to the users • Simple search functionality • Collaboration services • Web services for providing the access layer to documented knowledge • Indexing services for full-text search of documents • Well organized central storage location (server, database)
