Abstract

This invention pertains to a dictionary-linked text base apparatus having a text searching function and text searching methods using this apparatus at various levels. This realizes a searched result with a higher degree of accuracy and, by linking a text base with an electronic dictionary, this invention enables searches at three levels: all texts containing the morpheme included in a searched object word at a morpheme level; all texts related to the grammatical attribute of the item in the electronic dictionary matching or including the morpheme at a syntactical level; and all texts related to no less than one concept of the item in the electronic dictionary at a semantic level. The invention includes an electronic dictionary for storing, in correspondence with an identifier for each item, no less than one morpheme identifier forming the item, an identifier of the grammatical attribute of the item, and a concept identifier. In addition, it includes a relative information part for showing an identifier for the related text in the electronic dictionary, in correspondence with each of the morpheme identifiers, the grammatical attribute identifier and the concept identifier in the electronic dictionary.

Claims

a text editing part, operatively connected to said input/output controlling part, for performing an edit processing control of a text in said text base; and

a data controlling part, operatively connected to said search controlling part, said dictionary editing part, and said text editing part, including said electronic dictionary, relative information part and text base.

3. A dictionary-linked text base apparatus according to claim 2, further comprising:

an input/output including a first part of said input/output controlling part;

a controlling device, operatively connected to said input/output device, including a second part of said input/output controlling part, said searching controlling part, said dictionary editing part, and said text editing part;

a secondary memory device, operatively connected to said data controlling device, for storing all information in said data controlling part; and

a primary memory device, operatively connected between said controlling device and said secondary memory device, for storing only the information necessary for processing information of said data controlling part stored in said secondary memory device.

4. A dictionary-linked text base apparatus according to claim 1 wherein:

said grammatical attribute identifier corresponding to an identifier of the item in said electronic dictionary is singular; and

either one of said morpheme identifier and said concept identifier can be in a complex form in which a plurality of respective identifier is sequenced, while at least an other one of said morpheme identifier and said concept identifier must be in a singular form in which only one respective identifier is used.

5. A dictionary-linked text base apparatus according to claim 1 wherein said relative information part comprises:

a morpheme table, operatively connectable to said electronic dictionary and said text base, for storing an item identifier in said electronic dictionary and a text identifier in said text base, corresponding to said morpheme identifier;

a grammatical attribute table, operatively connectable to said electronic dictionary and said text base, for storing said item identifier in said electronic dictionary and said text identifier in said text base, corresponding to a said grammatical attribute identifier; and

a concept table, operatively connectable to said electronic dictionary and said text base, for storing the item identifier in said electronic dictionary and the text identifier in said text base, corresponding to said concept identifier.

6. A dictionary-linked text base apparatus according to claim 5 wherein:

said text base stores a sequence of said morpheme identifiers in said text, a sequence of said grammatical attribute identifiers, and a relationship of said concept identifiers, corresponding to identifiers of respective text.

7. A dictionary-linked text base apparatus according to claim 6 wherein:

when a searching level is a morpheme level, a primary memory device for a searching process reads said morpheme table in said relative information part, the elements in said morpheme table are compared with a morpheme which is a searched object word, said text base is searched by using the text identifier corresponding to said morpheme identifier of an element matching said searched object word, and a text is created by searching a morpheme table using the morpheme identifiers sequenced in correspondence with the identifier for the searched text.

8. A dictionary-linked text base apparatus according to claim 6 wherein:

when a searching level is a syntactical level, a primary memory device for a searching process reads said morpheme table and said grammatical attribute table in said relative information part, the elements in said morpheme table are compared with a morpheme which is a searched object word, said electronic dictionary is searched by using an identifier for an item in said electronic dictionary corresponding to the identifier for the element matching said searched object word, said grammatical attribute table is searched by using said grammatical attribute identifier corresponding to the identifier for the searched item, and by presenting at least one element searched in the grammatical attribute table, it is determined whether said element and a user'"'"'s searching request match;

said text base is searched by using a text identifier corresponding to said grammatical attribute identifier of an element in said grammatical attribute table matching the user'"'"'s searching request, and a text is created by searching the morpheme table using the morpheme identifiers sequenced in correspondence with the identifiers for the searched text.

9. A dictionary-linked text base apparatus according to claim 6 wherein:

when a searching level is a semantic level, a primary memory device for a searching processing reads said morpheme table and said concept table in said relative information part, the elements in said morpheme table are compared with a morpheme which is a searched object word, said electronic dictionary is searched by using the identifier for the item in said electronic dictionary corresponding with said morpheme identifier for the element matching said searched object word, and said concept table is searched using said concept identifier corresponding to the identifier for said searched item,

by presenting at least one element searched in said concept table, it is determined whether said element and the user'"'"'s searching request match,

said text base is searched using the text identifier corresponding to said concept identifier of the element matching the user'"'"'s searching request;
