Abstract: A system and method for optimization of a plurality of campaigns for programmatic employment advertising. Preferably such optimization is guided according to the goals and parameters of each campaign.

Abstract: A system and method for programmatically testing a plurality of employment posting variants in a systematic and hierarchical manner, while being guided by current and historical employment posting data, including with regard to costs and success rate. According to at least some embodiments, the system first creates a plurality of different job posting title and text variants, as an expanded set of job postings or “expansion”. Optionally particular feature(s) are selected for expansion, such as for example job posting location or geography, job title, description and so forth. Such particular feature(s) may be selected according to historical data. Optionally all expanded job postings are considered for testing, but alternatively, the set of job postings may be initially limited according to an analysis of historical data.

Abstract: A method of machine learning for generating a predictive model of a response characteristic based on historical data elements using a processor may include receiving historical data elements and historical values for the response characteristic related to uses of the historical data elements in web pages. A plurality of key-value pairs may be generated defining values of a plurality of predefined features representing properties of the historical data elements. Each of a plurality of n features may be represented by an axis in an n-dimensional space are extracted from the historical data elements. The extracted plurality of key-value pairs for each historical data element may be projected onto the n-dimensional space. The plurality of vectors may be input into a model generator to generate a predictive model predicting a value of the response characteristic for a new data element.

Abstract: A system and a method for automatic facility management, including automatic analysis of at least one facility system according to at least one facility plan.
