Abstract
Incomplete and fuzzy portions in input information are detected by making a reference to world knowledge and knowledge of a specific field in a knowledge base prior to understanding the input information indicating a concept. The detected incomplete portion is completed and the detected fuzzy portion is resolved. The knowledge base makes a reference to knowledge of other concepts when the value of an instructed attribute of a specific concept is acquired. Moreover, a concept common to and upper than a plurality of concepts can be determined so that another word, concept or meaning is searched for from one word, concept or meaning.
Claims17
An information processing system comprising:
- input means for inputting information representing a concept;
- a knowledge base for storing knowledge including rules for completion of the concept;
- detection means which refers to conditions of the rules for completion in said knowledge base to detect an incomplete portion of the inputted information supplied from said input means;
- completing means for completing the incomplete portion detected by said detection means by referring to actions of the rules for completion in said knowledge base;
- and
- output means for outputting the inputted information, the incomplete portion of which having been completed by said completing means.
3 more elements
An information processing method comprising the steps of:
- inputting information representing a concept;
- a knowledge based for storing knowledge including rules for completion of concept;
- detecting an incomplete portion of the information inputted in said inputting step by referring to conditions of rules for completion of concept stored in a knowledge base;
- completing the incomplete portion detected in said detecting step by referring to actions of the rules for completion in said knowledge base;
- and
- outputting the inputted information, the incomplete portion of which having been completed in said completing step.
3 more elements
An information processing system comprising:
- concept input means for inputting information representing a word, a concept associated with a word, and a meaning of a word;
- a concept knowledge base storing knowledge of concepts associated with words and expressed by words and conditions for use;
- a meaning knowledge base storing knowledge of the meanings of the words;
- a grammar knowledge base storing knowledge of relationships among words in a case where the words are used in a sentence;
- instruction means for instructing the searching of the concept knowledge data base and/or the meaning knowledge data base when a word is input by said input means, and for instructing the searching of the meaning knowledge data base and/or the grammar knowledge data base when a concept is input by said input means, and for instructing the searching of the grammar knowledge data base and/or the concept knowledge data base when a meaning is input by said input means;
- searching means for searching the concept knowledge data base and/or the meaning knowledge data base when a word is input by said input means, for searching the meaning knowledge data base and/or the grammar knowledge data base when a concept in input by said input means, and for searching the grammar knowledge data base and/or the concept knowledge data base when a meaning is input by said input means all in accordance with the instructing of said instruction means;
- and
- output means for outputting a result of search performed by said searching means.
5 more elements
An information processing system comprising:
- a knowledge base for storing values of predetermined and plural attributes of objects and categories of the objects, wherein each object has associated therewith a plurality of attribute slots, wherein each attribute slot defines a different attribute of the object and includes a value of the attribute, wherein the attribute slots can also include a pointer identifying an attribute of another object providing further information about the attribute of the attribute slot including the pointer;
- instruction means for instructing the reading of an attribute slot and its associated value;
- reading means for reading the one attribute slot and its associated value as instructed by said instruction means, from said knowledge base;
- and
- control means for controlling said reading means to read the attribute of the another object pointed by a pointer in said knowledge base in response to said reading means reading the pointer.
2 more elements
An information processing system comprising:
- a knowledge base for storing values of predetermined and plural attributes of objects and categories of the objects, wherein each object has associated therewith a plurality of attribute slots, wherein each attribute slot defines a different attribute of the object and includes data further specifying the attribute, wherein at least one attribute is shared by a plurality of objects, wherein the data of the plurality of objects further specifying the at least one shared attribute is arranged and stored hierarchically in said knowledge base;
- instruction means for instructing the reading of the at least one shared attribute of two objects of the plurality of objects;
- reading means for reading an attribute slot of two objects which comprises the at least one shared attribute as instructed by said instruction means from said knowledge base;
- and
- determining means for reading the hierarchically arranged data further specifying the at least one shared attribute to determine a common portion of the hierarchically arranged data shared by the read attribute slots of the two objects.
