Abstract: Technical interviewing is important for organizations for assessing a candidate to make hiring decision. For effective technical interviewing, predicting difficulty of long form technical questions is crucial. The present disclosure provides systems and methods for predicting difficulty of long form technical questions using weak supervision from textbooks. Further, zero shot pre-trained large language models and unsupervised template-based technique are used for generating questions. Furthermore, a difficulty score is assigned to the generated questions based on context difficulty and task difficulty. The context difficulty for the generated questions is computed using hierarchical structure of the textbooks, and the task difficulty is computed by determining a similarity between the generated questions and Bloom's taxonomy levels.

Abstract: A method for optimizing quantitative return-on-investment performance in an online advertising campaign. The advertising campaign has a finite campaign period and a finite spending budget within a system that includes a bidding facility for bidding on a plurality of advertising slots. The method seeks to optimize performance of the campaign according to an objective function that includes a marginal return on investment variable, which variable is maintained throughout a series of iterations. Techniques are disclosed for capturing campaign parameters and constraints from advertisers, and mathematical techniques are used in determining a selected advertising slot upon which to bid at each iteration. A tracking system provides a history of winning bids and forecast of inventory. After bidding, the value of the marginal return on investment variable is changed based on the results of the bidding. The next bidding operations are based on the value of the marginal return on investment variable.

Abstract: A system for performing adaptive bidding to secure Internet advertising impressions in an auction. Included are systems for analyzing advertising campaign objectives, including a campaign period, a target number of impressions, a target budget. An exemplary technique defines a bidding agent for performing the adaptive bidding seeking the minimum target spending of the budget. Objective results of the campaign such as average cost per won impression, total campaign duration relative to desired campaign period, and total expenditure relative to campaign budget can be optimized based on an empirically determined forecast. Techniques for adapting bids include statistically modeling winning bids during an exploration bidding phase, performing iterations for adjustment of the bid amounts using learn-while-bid adaptive bidding, learn-then-bid adaptive bidding, and guess-double-adjust adaptive bidding.

An ad story from the pool of ad stories is chosen by dynamically evaluating ad value associated with each ad story in the pool based on continued surfing by the user such that the identified ad story provides the maximum ad value when rendered on the webpage. The identified ad story is scheduled for rendering on the webpage while providing relevant ad content at the webpage.

Abstract: A social network is managed by applying connectivity and similarity measures to social network information to identify possible new relationships between social network users, and then automatically suggest those identified relationships to the social network users. The social network information can include user profile information and indicate existing social relationships between the users in the social network. Users can provide feedback regarding the suggestions, including indications whether the relationship was accepted, consummated, or declined. The social network information can be updated using the feedback. Similarity measures can be based on one or more of shared contacts, or common interests or activities, or content associated with social network users, or ratings within the social network of users and/or their content. Possible relationships having similarity measures that suggest the users likely to already know each other, can be omitted and not suggested.

Abstract: A sponsored search auction system is configured to receive bids for queries from advertisers. Each bid on a particular query relates to a particular context, such as an age, sex, or location of a user that may submit the query to a search engine. A valuation is provided for each available context of the query by each advertiser. The bids are processed to generate one or more context bundles. The context bundles are groupings of contexts. Not necessarily all contexts are bundled. The bundled and unbundled (if present) contexts may be sold to the advertisers as bundled. Selling of contexts in bundled form may enable increased revenue to be generated as compared to auction systems that sell each context separately or sell contexts bundled into a single group.

Abstract: The various embodiments of the present invention provide systems and methods to incentivize online users to reveal their online purchasing interests so that advertisements matches their online purchasing interests can be displayed to the users. When users follow the displayed advertisements that match their online purchasing interests to make purchases, users are rewarded by sharing a portion of the advertising (or advertisement) revenue that are related to their online purchases and are collected by the web site(s) that displays the advertisements. The payout for the advertisements by the advertisers to the web site(s) is based on click-per-action (CPA) model, which generally pays more substantially per purchase action. Therefore, the users, who share a portion of the advertisement revenue directly related to their online purchases, can receive more substantial rewards. The reward is mainly monetary (or financial gain) and can come in various forms, such as discount, or credit.
