Abstract
Abstract A semantic network is described in which data is stored in data storage areas at nodes of the network, there being a root node from which all other nodes depend, in a branched structure, and in which data stored at each node includes relationship information about related nodes other than nodes linked by a branch from said node. The relationship information includes a token identifying the type of relationship. The other node in a relationship may be a virtual node, which does not actually exist, but whose data content is stored within the relationship information.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
124 words
A database arranged as a semantic network in which: data is stored in data storage areas at nodes of the network, there being a root node from which all other nodes depend in a branched structure; data stored in data storage areas at a first node includes: a value of a subject of the first node; and relationship information about one or more relationships from the first node to one or more second related nodes, said relationship information including a token identify a relationship type and second nodes, not being linked in the branched structure to said first node wherein the token is a shortened representation of a corresponding relationship name; and the database comprising information relating the tokens to the corresponding relationship names.
Claim 2
Dependent Claim
124 words
A database arranged as a semantic network in which: data is stored in data storage areas at nodes of the network, there being a root node from which all other nodes depend in a branched structure; data stored in data storage areas at a first node includes: a value of a subject of the first node; and relationship information about one or more relationships from the first node to one or more second related nodes, said relationship information including a token identify a relationship type and second nodes, not being linked in the branched structure to said first node wherein the token is a shortened representation of a corresponding relationship name; and the database comprising information relating the tokens to the corresponding relationship names.
Claim 3
Dependent Claim
27 words
A database as claimed in claim 1 in which said relationship information includes a flag indicating a type of a related subject corresponding to said related node.
Claim 4
Dependent Claim
30 words
A database as claimed in claim 2 in which said relationship information includes a flag indicating that the relationship points in a direction towards this node from a related node.
Claim 5
Dependent Claim
33 words
A database as claimed in claim 1 in which said relationship information relates to a virtual node and said relationship information itself includes the data which would have been in the virtual node.
Claim 6
Dependent Claim
27 words
A database as claimed in claim 4 in which said relationship information includes a flag indicating a type of a related subject corresponding to said related node.
Claim 7
Dependent Claim
35 words
A database as claimed in claim 5 in which the data for said virtual node is stored at a location pointed to by the relationship information, the location not being part of the branched structure.
Claim 8
Dependent Claim
30 words
A database as claimed in claim 5 in which said relationship information includes a flag indicating that the relationship points in a direction towards this node from a related node.
Claim 9
Dependent Claim
29 words
A database as claimed in claim 7 in which branches in said branched structure comprise a relationship, whose flag indicates that the relationship is part of the branched structure.
Claim 10
Dependent Claim
30 words
A database as claimed in claim 8 in which said relationship information includes a flag indicating that the relationship points in a direction towards this node from a related node.
Claim 11
Dependent Claim
137 words
A computer system comprising a memory, a display device, an input device and a database arranged as a semantic networks, in which: data is stored in data storage areas at nodes of the network, there being a root node from which all other nodes depend in a branched structure; data stored in data storage areas at a first node includes: a value of a subiect of the first node; and relationship information about one or more relationships from the first node to one or more second related nodes, said relationship information including a token identify a relationship type and second nodes not being linked in the branched structure to said first node, wherein the token is a shortened representation of a corresponding relationship name; and the database comprising information relating the tokens to the corresponding relationship names.
Claim 12
Dependent Claim
137 words
A computer system comprising a memory, a display device, an input device and a database arranged as a semantic networks, in which: data is stored in data storage areas at nodes of the network, there being a root node from which all other nodes depend in a branched structure; data stored in data storage areas at a first node includes: a value of a subiect of the first node; and relationship information about one or more relationships from the first node to one or more second related nodes, said relationship information including a token identify a relationship type and second nodes not being linked in the branched structure to said first node, wherein the token is a shortened representation of a corresponding relationship name; and the database comprising information relating the tokens to the corresponding relationship names.
Claim 13
Dependent Claim
28 words
A computer system as claimed in claim 10 in which said relationship information includes a flag indicating a type of a related subject corresponding to said related node.
Claim 14
Dependent Claim
31 words
A computer system as claimed in claim 11 in which said relationship information includes a flag indicating that the relationship points in a direction towards this node from a related node.
Claim 15
Dependent Claim
34 words
A computer system as claimed in claim 10 in which said relationship information relates to a virtual node and said relationship information itself includes the data which would have been in the virtual node.
Claim 16
Dependent Claim
28 words
A computer system as claimed in claim 13 in which said relationship information includes a flag indicating a type of a related subject corresponding to said related node.
Claim 17
Dependent Claim
36 words
A computer system as claimed in claim 14 in which the data for said virtual node is stored at a location pointed to by the relationship information, the location not being part of the branched structure.
Claim 18
Dependent Claim
31 words
A computer system as claimed in claim 14 in which said relationship information includes a flag indicating that the relationship points in a direction towards this node from a related node.
Claim 19
Dependent Claim
30 words
A computer system as claimed in claim 16 in which branches in said branched structure comprise a relationship, whose flag indicates that the relationship is part of the branched structure.
Claim 20
Dependent Claim
31 words
A computer system as claimed in claim 17 in which said relationship information includes a flag indicating that the relationship points in a direction towards this node from a related node.
