In an embodiment, the size of a filter in a search engine is dynamically adjusted in order to reduce filter error. The filter, for example, may be a domain filter that contains domain(s) of preferred search results. A search engine processes the query and the domain filter to create a set of search results that are relevant to the query terms and for which a selected portion of the search results satisfy the domain filter, in that such portion of the documents come from domains in the filter. The search results may then be provided to the user, as a set of search results that are relevant to the query terms and which include some portion of results that match the query labels. The construction of the domain filter may be done with a Bloom filter approach, using domain prefixes from annotations.

The present disclosure provides a webpage data search method, device and system. The method may include the steps of: obtaining a search keyword; searching through multiple search engines according to the search keyword and obtaining search results from the multiple search engines; obtaining quality information of the search results; determining a recommended search result from among the search results from the multiple search engines according to the quality information; and providing the recommended search result to one or more users. The disclosure may provide for automatic selection of search results with increased relevance and provide increased flexibility for users in comparing search results. Thus, the disclosure may simplify user operation and improve search quality.

The invention relates to an SE (search engine) ordering method based on user participation, and belongs to the technical field of software. The method is based on an SE ordering system, a user scores all information and search results by expressing opinions such as agreement, love, disagreement, rejection and the like on a display list of search results, according to scores of the search results, one search result with high scores is ordered at the top automatically according to a high-low order of scores when the search results are searched next time, and a program for preventing malicious scoring is set. Systems which are established for implementing the method comprise a user and SE ordering system, a model processing system and an output system. With the adoption of the method, user participation can be enhanced, opinion expression is performed aiming at search information, reference is provided for other users, so that the search quality can be effectively improved, the user can perform selection by referring to opinions, the search time of the user is effectively shorted, and work efficiency and ability of obtaining information are improved.

The invention discloses a high-voltage breaker moving contact movement track real-time identification method based on priori knowledge. The method includes the following steps: a red square marker is fixed on a breaker insulating pull rod; the position of a high-speed camera is adjusted, and a marker image sequence is obtained; a tracking target template is determined; a maximum search range of a current frame is determined according to priori knowledge; a priority search sequence of a next frame of target is determined according to priori knowledge, and coarse search is performed on each pixel point of an embedded dual hexagons in sequence; rhombus fine search is performed around an optimal pixel point, the position of the target is determined, and a priori knowledge base is updated at the same time; and the position of the target in an image in each frame is recorded, and a movement track is generated. The high-voltage breaker moving contact movement track real-time identification method provide by the invention is based on a breaker motion characteristic monitoring priori knowledge base, makes improvements on an existing target tracking algorithm, fully excavates and utilizes effective information of the priori knowledge base, proposes an embedded dual hexagon-rhombus fast search algorithm on this basis, and can realize real-time and precise moving contact movement track identification.

The invention discloses a water resource information vertical search method based on a cloud platform. The method comprises the following steps: constructing a seed site list; capturing the water resource webpage of the seed site by using a web crawler and preserving the water resource webpage into a local webpage database; constructing a water resource terminology standard set, and organizing all water resource terminologies in the standard set into a dictionary for the water resource field; carrying out analysis and text extraction on the webpage in the local webpage database; extracting the semi-structured data of the webpage to be structured data which can be conveniently stored and indexed; establishing inverted index for the structured data of the webpage and storing the index result in the index database; and searching the index database according to the search request submitted by a user and returning the search result. According to the method, the quality of the water resource webpage can be optimized, the search quality is improved, distributed search is realized, and the search efficiency is improved.

The present invention relates to a method computer program product for datamining with constant search time, the method and computer program product comprises the steps of: traversing a search tree to a leave, retrieving a one or more data store identifier from said leave, read data pointed to by said data store identifier, locating one or more value in said data, referencing one or more data descriptor, retrieve the n-nearest data descriptor neighbors, terminate said search.

The invention relates to a search engine ranking method based on user participation and belongs to the technical field of software. The method is based on a search engine ranking system and a user can express approval, like, disapproval, opposition and other opinions on a display list of search results and perform scoring on all of information and search results; and according to score values of the search results, in next search of the results, the results will be automatically ranked according to the score values, the results with high scores will be ranked ahead and a program for preventing malicious scoring is set. A system established for implementing the method comprises users, the search engine ranking system, a model processing system and an output system. By adopting the method of the invention, the user participation can be strengthened, the expression of the opinions can be performed on the search information and other users can take the opinions as references, thereby effectively improving search quality, facilitating the selection of the users by referring to the opinions, further effectively reducing search time of the users and improving handling efficiency and capability of learning information.
