Abstract: A method and an apparatus for serializing a plurality of information elements that are extracted from a plurality of information sources and represented by nodes in a semantic network. The nodes are connected to other nodes via a plurality of connecting edges, and each of the connecting edges has at least one edge property value. The method includes selecting an initial node of the plurality of nodes and determining one of the at least one node property values of first order connecting nodes connected to the initial node, determining a first node connected to the initial node by the connecting edge having a highest value of the at least one node property value, examining further first order connecting nodes connected to the first node and determining a relevance order of the further first order connecting nodes connected to the first node and serializing the plurality of information elements in accordance with the relevance order of the further first order connecting nodes to produce a serial list.

Abstract: A method and an apparatus for semantic parsing of electronic text documents. The electronic text documents can comprise a plurality of sentences with several language components. The method comprises analyzing at least one sentence of the electronic text document and dynamically generating a graph from the analyzed sentence of the text document. The graph represents a semantic representation of the analyzed one or more sentences. The method continues the analysis until an ambiguous sentence is determined and analyzed by evaluating at least a portion of the generated graph.

Abstract: A method and an apparatus for extraction of information from a plurality of electronic text documents. The method comprises defining and generating a reference graph. The reference graph represents a specific theme of a reference text document. The method further comprises comparing the reference graph with a second graph using an extraction criterion. The second graph represents a specific theme of a second text document. Further, the result of the comparison is checked if the result falls within the extraction criterion boundary value. Then, the checked result of the comparison is extracted if the result falls at least within the extraction criterion boundary value. The method continues the comparison and the checking of the result of the comparison of the defined and generated reference graph with a further graph.

Abstract: A method and apparatus for the collaborative knowledge-based creation and extension of an information graph are taught. The method comprises a first step of retrieving items of a given, human-made information graph in a database, a second step of retrieving relations between the given elements, not yet drawn in the information graph or of retrieving characteristics of the given elements, or of retrieving information about the given elements, a third step of attaching these new relations and/or retrieved elements to the given graph on a graphical device and a fourth step of manually adding these proposed items of information to the information graph. The items of information include elements of information and relations between the elements of information. The elements of information are displayed as nodes on the relation map and the relations as lines on the relation map.
