  • Patent number: 12165744
    Abstract: A method for making a recombinant gene includes searching a database using a nucleotide sequence of a coding region, a nucleotide sequence that encodes an amino acid sequence, or an amino acid sequence, of a gene, for one or more nucleotide sequences having homology; selecting one or more nucleotide sequences other than nucleotide sequences only derived from a genome from the selected nucleotide sequences; for ones of the selected one or more nucleotide sequences comprising an upstream or downstream nucleotide sequence, analyzing whether the upstream or downstream nucleotide sequence is a functional sequence to select one or more first functional sequences; for ones of the selected one or more nucleotide sequences comprising no upstream or downstream nucleotide sequence, analyzing whether a gene information has any description indicating a functional sequence to select one or more second functional sequences; scoring the selected functional sequences; and selecting one or more functional sequences.

  • Publication number: 20210294860
    Abstract: A system extracts one or more topic words from a set of seed documents of one or more seed documents, and creates a useful document model which is a model including the one or more topic words and a weight of each of the one or more topic words. A seed document is a document which may be a useful document. The system extracts one or more documents matching a search condition from a document search range including one or more documents according to a search request in which the search condition is specified. The system determines, for each of the one or more extracted documents, a document score of the document based on the above-described useful document model, and outputs a search result on descending order of document scores of the one or more extracted documents.

  • Patent number: 8321485
    Abstract: To achieve high speed document search, an inverted index is compressed at high compressibility by an encoding method decodable in a high process speed. In compressing an identification number of a document to obtain a byte sequence by the variable byte method, w bits are used to represent the number of occurrences of the indexing term in the document, and x bits are used to represent additional information of the posting, where x and w are integers given as parameters. When the number of occurrences cannot be represented within w bits, a certain value indicating a numeric value that cannot be represented by w bits is stored is written to the said w bits, and anther byte sequence that represents the value by the variable byte method follows. Additionally provided is a means for reading a compressed posting from any position of a list of postings called inverted lists, allowing a binary search on an inverted list.

  • Patent number: 7966307
    Abstract: A document search apparatus capable of an index-type search and a scan-type search performs a search in a combination of the two search types while compensating for the disadvantages of the two search types with each other. A search query for index-type search and a search query for scan-type search are constructed based on a search query consisting of a logical formula of keywords. Then, a character 2-gram for performing an index search is set to shorten the whole search time, and the index-type search is performed. Finally, a scan-type search is performed on this search result of the index-type search.

  • Publication number: 20080178297
    Abstract: An information management system comprises a coordinate acquiring device for specifying a position on a paper sheet and a content server for storing data. The content server stores document data, event data, and stroke information. When the coordinate acquiring device specifies the position of the stoke information on the paper sheet concerning the document data, the content server retrieves event data relevant to the stroke information corresponding to the specified position, judges whether or not the user who has specified the position of the stroke information can read the retrieved event data, and transmits the event data if the user is judged to be able to read the event data.

  • Patent number: 7277881
    Abstract: Ordering is properly performed for document databases registered in an associative search server. In an associative search server capable of performing an associative search by correlating a plurality of document databases, the history of the associative search is stored as an associative search recording table by associative search recording table storing means. By using this associative search recording table, a showing order of document databases presented by document database selecting means is properly set by showing order changing means. Alternatively, by registration fee calculating means, calculation is properly carried out as to registration fees of the document database registered in the associative search server.

  • Publication number: 20060179041
    Abstract: Both a first kind of terms and a second kind of terms are designated. A user desires to obtain a relationship between these terms. By employing relations between these terms having been previously stored in a storage in advance, the manner in which these terms are correlated is dynamically displayed, while nodes and edges are gradually increased. In this manner, relations are easily found for concepts (terms) that seem not to be correlated, and an efficient search can also be performed.

  • Patent number: 7065518
    Abstract: A system for displaying the results of a search provided by one of two different search systems enabling continuous searching. One search system includes a search takeover data production command used to output search takeover data articles from the search. The other search system includes a search takeover data reading command used to read search takeover data. A document identifier correspondence table associates the identifiers specified in the search takeover data. When a user clicks a search system transfer instruction button in one search system, the search takeover data producing command is executed to produce search takeover data which is passed to the other search system. The latter search system regards the list of identifiers of articles which was passed by the search takeover data reading command as the search results, and thus operates continuously.
