摘要:
The invention relates to a method for searching within elements of a hierarchically structured database (10), wherein each element has one or more hierarchically structured nodes for defining attributes of said element and wherein one or more nodes of the searched element must fulfill one or more search conditions (c0,ci, . . . ) the method comprising the steps of a. selecting a plurality of nodes and assigning a unique identifier (EID) to each of the selected nodes; b. creating a reference index (20), that allows to derive for each unique identifier (EID) of a selected node the corresponding element of the database (10); c. for each of the one or more search conditions (c0,ci, . . . ): retrieving a set (L, Ei) of unique identifiers for ancestor nodes of nodes, which fulfill the respective search condition (c0,ci, . . . ); d. intersecting the sets (L, Ei) to obtain a final set (L) of unique identifiers; and e. retrieving the searched elements of the database (10) based on the final set (L) of unique identifiers (EID) and the reference index (20).

A method of and system for associating an electronic signature with an electronic record in a computer system. In one embodiment the method comprises allowing a user to define an event that, upon occurrence, generates an electronic record that requires an electronic signature; allowing a user to define the fields stored in the electronic record; allowing a user to generate a map that maps data from underlying database tables to at least some of the fields defined for the electronic record; allowing a user to define a layout for displaying data in the electronic record on a computer display when an electronic signature for the data record is collected; allowing a user to identify a signatory approver for the electronic record; generating the electronic record and displaying the electronic record to the signatory approver according to the defined layout in response to the occurrence of the event; receiving an electronic signature from the signatory approver; and associating the electronic signature with the electronic record. Some embodiments further comprise verifying the electronic signature prior to associating the signature with the electronic record.
摘要:
A query in which a sibling relationship among document parts, which are elements of a structured document, can be designated as a search condition is input, and a query tree which represents the query in a tree structure is created. A query converting unit refers to a hierarchical index in which a hierarchical relationship among document parts of each structured document to be searched is expressed in a tree structure, and converts the query tree to a Boolean expression. A text-index referring unit refers to a text index in which is registered information representing a relationship between each set including a character string in text data and a part-ID of a meta part and a document-ID of a document, thereby searching a document corresponding to the Boolean expression converted from the query tree.
摘要:
An index structure of metadata provided for searching for information on contents and a method for providing indices of the metadata, and a method and an apparatus for searching for the metadata using the index structure of the metadata are provided, in which the index structure of the metadata includes values of multi-keys and identification information of the metadata corresponding to the values of the multi-keys, wherein the multi-keys are structured by a combination of predetermined fields of the metadata.
摘要:
A method and a computer system for indexing and searching the data content of nested field records, such as those in Extensible Markup Language (XML). The system includes an indexing and searching engine that constructs an improved full-text search index on the input XML data and then performs searches using the index. The system supports exact matches and partial matches using a wildcard character. The method transforms the input XML data into a form that encodes the data structural information by suffixing each word with its corresponding field qualifiers or an equivalent numerical pattern thereof. The resulting encoded words are then stored in a full-text index structure. Various types of full-index search may be performed. One alternative embodiment is to combine string matching and numeric or integer pattern matching to identify a particular word in a particular field. The portion of the word without field qualifiers is matched against the words in the index, and the pattern of numerals representing the word's field qualifiers is matched against the numeral patterns of the words in the index that correspond to their respective field qualifiers. Therefore, evaluation of complex field criteria is reduced to simpler and faster numeric matching.

A method and system for conducting a search on a network is disclosed. The network has a plurality of sites. One or more of the sites has a plurality of documents wherein at least one of the documents comprises a plurality of tags. The method and system comprises identifying at least one of the plurality of tags, receiving a query, parsing the query, and matching the parsed query with at least one of the plurality of tags of the at least one of the plurality of documents. Accordingly, through the use of a method and system in accordance with the present invention, the extraction of information from networks comprising XML documents is done in a more precise fashion.

To efficiently search an evaluation result of a plurality of XPath expressions with respect to a data file such as an XML document: an evaluation result of an XPath expression is obtained by generating a data structure with a redundant element by evaluating what common part or dependency has been omitted from a plurality of XPath expressions to be evaluated, and then the data structure is used with respect to a data file to be processed.
摘要:
A system for automatically creating databases containing industry, service, product and subject classification data, contact data, geographic location data (CCG-data) and links to web pages from HTML, XML or SGML encoded web pages posted on computer networks such as the Internet or Intranets. The web pages containing HTML, XML or SGML encoded CCG-data, database update controls and web browser display controls are created and modified by using simple text editors, HTML, XML or SGML editors or purpose built editors. The CCG databases may be searched for references (URLs) to web pages by use of enquiries which reference one or more of the items of the CCG-data. Alternatively, enquiries referencing the CCG-data in the databases may supply contact data without web page references. Data duplication and coordination is reduced by including in the web page CCG-data display controls which are used by web browsers to format for display the same data that is used to automatically update the databases.
摘要:
A method, apparatus and article of manufacture for computer-implemented creation of an index in a database system is defined, wherein a structured document, interactively entered by an operator or already stored in the database system, is parsed into at least one corresponding element, then abstracted using a predefined abstraction procedure to obtain a set of abstracted values, the set of abstracted values being stored in the index for efficient execution of structured queries.

A text cataloging method includes a step of cataloging already-analyzed-text data obtained from an analysis of a logical structure of a text to be cataloged in a text database, a step of creating a structure index by sequentially superposing logical structures of texts to be cataloged, wherein a single metaelement is used for representing a group of elements in the texts having the same position of appearance in one of the texts and the same element type, a single piece of meta-character-string data is used for representing a group of pieces of character-string data in the texts having the same position of appearance in one of the texts, and a context identifier is assigned to each metanode composing a tree-like structure of the structure index for uniquely identifying the metanode; a step of generating structured-full-text data composed of definitions of associative relations between all pieces of character-string data-included in already-analyzed-text data of each text to be cataloged, and context identifiers of pieces of meta-character-string data in the structure index used for representing the pieces of character-string data; and a character-string-index updating step, including the sub-steps of extracting partial character strings, generating structured-character-position information, and updating a character-string index.
