Example one
Fig. 1 is a schematic flow chart of a method for establishing a patent database with double search according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a method for building a patent database with double search, where the method includes:
step 110: a first patent document is obtained, wherein the first patent document has a first keyword.
Specifically, the first patent document is a target patent document, that is, a patent document to be searched, and a keyword thereof is determined by analyzing the content, title, and classification number of the first patent document, and the keyword is an information content input by a user when using a search engine, and can maximally summarize the information content that the user desires to search for. Keywords that are spoken in the search engine optimization SEO industry often refer to the core and main content of a web page. For a search engine, your web page is mainly about what aspect is that aspect can be attributed one (more often multiple) keyword. For a patent document, a keyword is a core description content of a patent document description subject, and a word capable of locating a main body and important invention content of the patent document.
Step 120: and obtaining a first patent database from the patent retrieval data platform according to the first keyword.
Specifically, after determining keywords of a first patent document, the keywords are used for searching a patent document database, the existing mature patent search data platform is mainly used for searching, such as enterprise search, patent office web pages and the like, the determined keywords are recorded through linking the patent search data platform, and a corresponding keyword patent document database is obtained, wherein the patent document database is a first patent database.
Step 130: a second patent document is obtained, both of which are the target patent documents.
Specifically, the second patent document is also a target patent document, that is, a patent document requiring a search, as in the first patent document, that is, the present embodiment has a double search request, and it is necessary to perform search processing on both the first patent document and the second patent document, and satisfy the search request concerning both the patent documents.
Step 140: determining whether the second patent document exists in the first patent database.
Specifically, the first patent database is obtained after the search processing of the first patent document, and the first patent database is a set of all patent documents which are obtained by searching the patent data platform through the first keyword of the first patent document and meet the requirement of the first keyword, namely are related to the first keyword. Whether the second patent document is in the first patent database or not, that is, whether the second patent document and the first patent document have a certain correlation or not is determined. The determination of whether the second patent document exists in the first patent database may be performed by searching using the title and/or the patentee information of the second patent document to determine whether the second patent document exists in the first patent document.
Step 150: and when the second patent document exists in the first patent database, obtaining a second keyword according to the second patent document.
Specifically, if the second patent document exists in the first patent database, it is described that the second patent document is related to the first patent document, and at least the second patent document has the same first keyword as the first patent document. In this case, the second keyword of the second patent document is determined according to the content, title, classification number information, and the like of the second patent document, the second keyword is a core word of the second patent document, and is a word capable of expressing the core content of the second patent document, and the second keyword may be the same as or different from the first keyword. And if the second keyword is the same as the first keyword, determining that the first patent database is a final patent search result, and if the second keyword is different from the first keyword, further performing search processing on the second keyword. In addition, in some patents, there may be a plurality of keywords, and the keywords may be further analyzed to determine the keywords that better meet the content of the invention of the second patent document as the second keywords, or the keywords may be searched separately. Of course, if there are a plurality of keywords, in which case the keywords are the same as the first keyword, the keywords may be removed and the search may be performed using another keyword other than the same keyword.
Step 160: and obtaining a second patent database from the patent retrieval data platform according to the second keyword.
Specifically, since the second patent database is obtained by performing data search again using the second keyword, which is the keyword of the second patent document, by using the patent search data platform, the second patent database is a collection of all patent documents including the second keyword in the patent documents that have been published in the past.
Step 170: and obtaining a third patent database according to the first patent database and the second patent database.
Specifically, a first patent database and a second patent database are obtained through analysis and search of a first patent document and analysis and search of a second patent document, in order to meet the double search requirements of the two patent documents, the two databases are merged, namely, the first patent database and the second patent database are merged to obtain a third patent database, the third patent database comprises all search results of the first patent document and the second patent document, and needless to say, repeated patents are possibly existed, the repeated patents are merged, so that the technical effects of processing the double patents according to the search requirements respectively, realizing automatic establishment of the double search result databases, ensuring the comprehensiveness of the search results and improving the search efficiency are achieved. Therefore, the technical problems that in the prior art, manual operation is needed to be carried out for double retrieval, the process is complicated, time and labor are consumed, and a retrieval database is incomplete are solved.
Further, the obtaining a third patent database according to the first patent database and the second patent database includes: judging whether the first keyword and the second keyword are words of the same type; and when the first keyword and the second keyword are words of the same type, obtaining a third patent database according to the first patent database and the second patent database.
Further, the same type means that keywords can be mutually replaced based on the first patent document and the second patent document in the patent data retrieval platform.
Specifically, when the first patent database and the second patent database are merged, firstly, whether the first keyword and the second keyword are words of the same type is judged, the same type judgment can be performed from multiple aspects such as the attribute, the word meaning and the used context of the first keyword, for example, the ratio given to the parameter is used for scoring, the similarity value is obtained through weighting calculation, then, the comparison is performed according to the set similarity threshold, and if the requirements are met, the first keyword and the second keyword are determined to be words of the same type. And when the first keyword and the second keyword meet the requirements of the same type of words, merging the first patent database and the second patent database, combining the first patent database and the second patent database and deleting the words repeatedly to obtain a finally determined retrieval database. The method realizes effective processing of double-patent retrieval results and ensures the integrity and the effectiveness of the retrieval database.
Further, after the determining whether the first keyword and the second keyword are words of the same type, the method includes: when the first keyword and the second keyword are not words of the same type, obtaining the number of the same patents in the first patent database and the second patent database; judging whether the number of the same patents in the first patent database and the second patent database meets a preset condition or not; and when the number meets the preset condition, obtaining a third patent database according to the first patent database and the second patent database.
Further, when the number meets a predetermined condition, the method includes: the number is up to 50% or more of the first patent database, and/or the number is up to 50% or more of the second patent database.
Specifically, if it is determined that the first keyword and the second keyword do not belong to the same type of word, that is, the first keyword and the second keyword cannot be replaced, the patents in the first patent database and the second patent database are further analyzed, the determination is performed according to the number of the same patents in the first patent database and the second patent database as a standard, when the number of the repeated patents in the first patent database and the second patent database is large, the content relevance of the two patents is also large, and when the number requirement is met, the first patent database and the second patent database are combined to obtain a finally determined search result, that is, a third patent database. If the number of the repeated patents in the first patent database and the second patent database is not large or is not large, the correlation between the first patent database and the second patent database is low or not correlated, and the correlation between the corresponding first patent document and the corresponding second patent document is also low or not correlated, at this time, the two patent databases cannot be merged, and the value of retrieval reference is not available. When the similarity of the number of the patent databases is judged, the number of the repeated patents is at least 50% of the number of the first patent database or/and the number of the repeated patents in the second patent database, and of course, the number of the repeated patents can be adjusted as required according to the reference requirement of the retrieval data result to ensure the effectiveness of the retrieval database.
