Abstract: Systems and methods for natural language communication with a computer. A builder module constructs tables in a database by generating concept symbols for each language element in an expression to form a string of ordered concept symbols, and, in a series of rounds, combining pairs of concept symbols into newly generated concept symbols to form shortened strings of concept symbols until a single concept symbol remains. Each generated concept symbol is stored in a row in the database. A parser module may then utilize the database to parse an input expression by identifying rows in the database that correspond to language elements of the input expression to generate a string of concept symbols, and, in a series of rounds, replacing pairs of concept symbols in the string of concept symbols by identifying rows in the database that comprise the pairs of concept symbols until a single concept symbol remains.

Abstract: A system for accessing a webpage through natural language communication with a computer comprises a registry database configured to store at least one table the table configured to store associations between a concept in a text string and all natural language variations of the text string and associated concept identifiers, the concept in the text string an variations thereof relating to an object; and a parser interfaced with the database and configured to receive the text string or a variation thereof, the parser further configured to identify the concept represented by the text string or variation thereof and associate the identified concept with the object.

Abstract: A system for natural language communication with a computer, comprising a database configures to store at least one table the table configured to store associations between concepts in a text string and associated concept identifiers; and a builder interfaced with the database, the builder configured to construct a concept defined by a text string by performing a process comprising the following steps: assigning a unique identifier to the concept, breaking the concept into sub-concepts, assigning a unique identifier to each sub-concept, using legal joins to join sub-concepts into higher order sub-concepts, assigning a unique identifier to the higher-order concepts, and repeating the steps until the higher order sub-concepts join to form the concept, and storing the concept, sub-concepts, higher order sub-concepts and unique identifiers in a table in the database.

Abstract: A system for knowledge representation in a computer that can enable unrestricted natural language communication with a computer, comprising a database configured to store at least one table, the table configured to store associations between concepts in a text string and associated concept identifiers; and a builder interfaced with the database, the builder configured to construct a table that represents knowledge defined by a text string, the text string comprising (n) operands and (n?1) operators, by performing a process comprising the following steps: combining concepts in the text string into first order sub-concepts according to precedence defined by the operators, combining the first order sub-concepts into higher order concepts according to the precedence defined by the operators, repeating the steps until the higher order sub-concepts join to form a concept that represents the entire text string, and storing the concept, first order sub-concepts, and higher order sub-concepts in the database.
