## Intelligent retrieval from database, Computer Engineering

Assignment Help:

Intelligent Retrieval from Database: Database system are large bodies of facts about some subjects, which are used to answer users queries about that subject. The design of database systems is a very active field in the area of computer science even today. From the point of view of AI. The field becomes even more interesting if the answers require deductive reasoning with the facts in the database.

There are numerous problems that confront an individual trying to build such an intelligent retrieval system.

a. The problem of understanding queries stated in an natural language like English.

b. Assuming that the system has fully understood the query how should it deduce the answer .

c. For the given facts there are some queries which require common knowledge.
