The invention relates to a job search recommendation method and system based on semantic matching. According to the job search recommendation method and system based on the semantic matching, by using a semantic matching technology, the job search is conducted, a job seeker can quickly obtain personalized position recommendation which conforms to experiences after providing his or her own basic information. The job seeker does not need to think hard about the possibilities of his or her position tiles and repeatedly conducts information inputting and screening; the job seeker does not need to be afraid that a large amount of irrelevant information is obtained and judged due to ambiguity of the position tiles; the job seeker does not need to face the situation that the a result can not be found after inputting the position title of a minority; the job seeker does not need to spend much time in looking over position descriptions item by item to determine whether the positions are relevant to himself or herself. The job search recommendation method and system based on the semantic matching aims at solving the several problems existed in a traditional position searching system.

Estimation method for unknown position based on internet initiative iteration detection

InactiveCN103077201AImplement Approximate Range EstimationSpecial data processing applicationsDatabase queryThe Internet
The invention relates to an estimation method for an unknown position based on internet initiative iteration detection. The estimation method comprises the following steps: 1, checking a user input position, and if the database query fails, utilizing a network engine to obtain a webpage set related to the position; 2, extracting a position description in the webpage and classifying; 3, calculating a credible rate Cs of a searching result, if the Cs meets a threshold Cmin, skipping to the step 5; 4, repeating the step 1 to step 3 for a fuzzy position in the searching result, till the credible rate meets the threshold or achieves a times limit; and 5, calculating a geographical range of the position description, fusing and obtaining an approximate geographical range of a target position. According to the estimation method provided by the invention, the rich and dynamically changing geographic knowledge resources in the internet are fully utilized and the approximate range of the unknown position is estimated. Specific to the text position description in various forms in the internet, a semantics based multi-scale position extracting method is adopted and a Point-Radius algorithm is utilized to estimate the approximate geographical range of the position.
