Abstract: The disclosed search engine and search engine system apply a variety of criteria to find specific information within a full-text dataset, even when its user cannot recall the exact text or exact spelling of the desired information. The criteria cause retrieval of text not only when the sequence of words in the query matches the sequence of words in the text identically but also when the difference between sequences is that one of the words in a sequence is missing, added, replaced, or replaced with a synonymous word or a word having phonetic similarity. Another criterion is that the two words in the query sequence differ in order from the two words in the text sequence to be retrieved. The above criteria are applied after stop list words are disregarded. The search engine accordingly enables a user to find text more easily in large full-text datasets by inexact text searching.

Abstract: A computing system identifies an incoming voice call from a user device to an agent device associated with the computing system. The computing system generates a transcription of the incoming voice call using one or more natural language processing techniques. The computing system extracts a problem description from the transcription. The problem description indicates a topic for the incoming voice call. A first machine learning model estimates a situation vector from the problem description. A second machine learning model identifies a pre-existing situation vector that closely matches the estimated situation vector. The computing system retrieves a situation description that corresponds to the identified pre-existing situation vector.

Abstract: A method involves receiving search queries, having search terms, submitted to at least one computerized search engine. For each query, a corresponding pairwise relation in the search queries is calculated. The corresponding pairwise relation is a corresponding probability of a potential edge relationship between at least two terms. Thus, potential edges are formed. A general graph of the terms is constructed by selecting edges from the potential edges. The general graph is nodes representing the terms used in the search queries. The general graph also is edges representing semantic relationships among the nodes. A hierarchical graph is constructed from the general graph by altering at least one of the edges among the nodes in the general graph to form the hierarchical graph.

Abstract: The present teaching relates to generating combination distributions for ads. A prediction model is obtained via machine learning with respect to a criterion. Training data are associated with multiple ads each having multiple attributes, and include combinations with recorded performance for each ad. Each combination has multiple assets representing respective attributes of an ad. Using the prediction model, performance of each combination of each ad can be predicted and used for generating combination distributions for the ads. Such generated combination distributions are then sent to an explore/exploit layer (EEL) at a frontend ad serving engine so that it can draw a combination associated with an auction winning ad for rendering on a webpage viewed by a user on a user device.

Abstract: The present teaching relates to generating combination distributions for ads. Features are computed based on training data associated with ads, each of which has a plurality of attributes. The training data include asset combinations with past performance thereof for each of the ads. Each combination includes multiple assets representing respective attributes of an ad. The features are used in machine learning to obtain an auxiliary model, which is used to generate combination distributions for each ad based on predicted performance for each combination associated with the ad. Such generated combination distributions are sent to an explore/exploit layer (EEL) for a frontend ad serving engine to draw a combination therefrom for an auction winning ad for rendering on a webpage viewed by a user on a user device.

Abstract: The present teaching relates to displaying ads. An explore/exploit layer (EEL) is provided at frontend ad serving engine for storing combination distributions with respect to multiple ads. Each ad has multiple attributes. Each attribute can be instantiated using one of multiple assets. The frontend ad serving engine requests a recommended ad for bidding an ad display opportunity in a slot of a webpage viewed by a user on a user device. The recommended ad is one of the multiple ads. When the auction is successful, a combination of assets for the ad is drawn from the combination distributions in EEL and each of the assets instantiates a corresponding attribute of the ad. The combination is transmitted to the user device to render the ad.

Abstract: Exemplary implementations of a thermally-efficient slidable fenestration assembly are glass window systems or glass door systems having one or more sliding glass panels. The fenestration assemblies are adapted to be mounted in an architectural structure such as a building or house. Accessory channels in the fenestration framework may be provided to facilitate nail-fin, retro-fit or screen adaptors as means to attach the assembly to the surrounding architecture. Stiles, tracks and rails of the assembly are specifically configured to reduce heat transfer across the fenestration assembly, while simultaneously maintaining the structural integrity and durability of the overall assembly. Certain stile, track and rail components may comprise materials of relatively low conductivities. Preferred stile configurations include interlock elements arranged to reduce the assembly's vulnerability to tampering from a position outside of the fenestration.
