4.component of expert system
The document discusses the components of an expert system, including the user interface, inference engine, and knowledge base. It provides details on each component: the user interface allows communication between the user and system, the inference engine applies rules to the knowledge base to derive conclusions, and the knowledge base contains factual and heuristic knowledge about the domain in the form of if-then rules. The knowledge is acquired from human experts and organized by a knowledge engineer.
Introduction and architecture of expert system
An expert system is an interactive computer program that uses knowledge acquired from experts to solve complex problems in a specific domain. It consists of an inference engine that applies rules and logic to the facts contained within a knowledge base in order to provide recommendations or advice to users. The first expert system was called DENDRAL and was developed in the 1970s at Stanford University to identify unknown organic molecules. Expert systems are used in applications like diagnosis, financial planning, configuration, and more to perform tasks previously requiring human expertise. They have benefits like increased productivity and quality, reduced costs and errors, and the ability to capture scarce human knowledge. However, they also have limitations such as difficulty acquiring and representing human expertise and an inability to operate outside their
Rule Based System
Rule based systems are specialized software that encapsulate human intelligence and knowledge to make intelligent decisions quickly and repeatedly. They represent knowledge using if-then rules and work memory. There are two types of rules - forward chaining which is data-driven and deductive, and backward chaining which is goal-driven and inductive. While rule engines are the core of applications, fully utilizing them requires additional components for interfacing, data exchange, data storage, and version management. Examples of companies using rule engines include Dell, Cisco, Vodafone, and Blue Cross Blue Shield.

Expert Systems
Expert systems are computer programs that use human knowledge about a specific domain to solve problems through reasoning. They gather knowledge from experts to create a knowledge base of facts and rules. A knowledge engineer collects data, designs the knowledge base and rules base, and creates the inference engine. The inference engine uses forward chaining, backward chaining, or a combination to reason through problems by applying rules to facts and generate solutions or further questions for the user through the interface.

Strict implementation of regulations is needed.

This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.

Understanding User Needs and Satisfying Them
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs

Expert system
- 1. Expert System Presented by: Mukul, Pankaj & Divya
- 2. Expert System: Meaning An expert system is a computer system that competes with the decision-making ability of a human expert. Designed to solve complex problems by reasoning about knowledge, like an expert, and not by following the procedure of a developer as is the case in conventional programming.
- 3. Meaning Continued It is a computer program that represents and reasons with knowledge of some specialist subject with a view to solving problems or giving advice It is divided into two parts. Fixed, independent of the expert system: the inference engine. Variable: the knowledge base. Conversational: A dialog interface to communicate with users.
- 4. Software architecture The rule base or knowledge base In expert system technology, the knowledge base is expressed with natural language rules IF ... THEN ... For examples :"IF it is living THEN it is mortal" "IF his age = known THEN his year of birth = date of today - his age in years.
- 5. The inference engine The inference engine is a computer program designed to produce a reasoning on rules. In order to produce a reasoning, it is based on logic. With logic, the engine is able to generate new information from the knowledge contained in the rule base and data to be processed.
- 6. Advantages Evolving an expert system is to add, modify or delete rules. Since the rules are written in plain language, it is easy to identify those to be removed or modified. Quick availability and opportunity to program itself. The reliability of an expert system is the same as the reliability of a database, i.e. good, higher than that of a classical program.
- 7. Disadvantages Knowledge collection and interpretation into rules, the knowledge engineering. Expert knowledge is not well understood: there is a lack of rules, rules are contradictory, and some are poorly written and unusable. Expert systems most often use an engine incapable of reasoning. Therefore, oftentimes the expert system works poorly and the project is abandoned
- 8. On a lighter side
- 9. Application field Highly interactive or conversational applications, IVR, voice server. Fault diagnosis, medical diagnosis Decision support in complex systems, process control, interactive user guide. Educational and tutorial software. Logic simulation of machines or systems Knowledge management. Constantly changing software.
- 10. Thank You IF= Nerds are bad, THEN = Politicians are… error !
Editor's Notes
- As the rule base is in everyday language (the engine is untouchable), expert system can be written much faster than a conventional program, by users or experts, bypassing professional developers and avoiding the need to explain the subject.
